Free ATI NU 160 Exam 1 Spring 2025 Questions

1.

A nurse enters a client's room and finds the client on the floor having a seizure. Which of the following actions should the nurse take

  • Insert a tongue blade in the client's mouth.

  • Place the client on his side.

  • Hold the client's arms and legs from moving.

  • Place the client back in bed.

Explanation

Correct Answer: B. Place the client on his side.

Explanation:

Placing the client on their side
is the priority action when managing a seizure. This prevents aspiration by allowing saliva and any potential vomit to drain from the mouth instead of being inhaled into the lungs. It also helps keep the airway open and reduces the risk of tongue obstruction. Additionally, turning the patient on their side protects them from injury by ensuring a safer position while the seizure runs its course.

Why the Other Options Are Incorrect:

A. Insert a tongue blade in the client’s mouth.

This is dangerous and outdated.

Inserting a tongue blade or any object into the mouth can cause injury
, including breaking teeth, damaging gums, or obstructing the airway.

During a seizure, the jaw may clench, and forcing an object in the mouth can worsen airway obstruction rather than prevent it.

C. Hold the client’s arms and legs from moving.

Restraining the client is unsafe because it can lead to musculoskeletal injuries such as fractures or dislocations. Seizure movements are involuntary, and holding the limbs down does not stop the seizure. Instead of restraining, the nurse should focus on preventing harm, such as removing nearby objects that could cause injury.

D. Place the client back in bed.

Moving a patient during a seizure is unsafe and can increase the risk of falls and further injury. The priority is to protect the patient where they are and allow the seizure to pass before repositioning them safely. After the seizure stops, the nurse can assess the client and assist them back to bed safely.

Summary:

The correct action is B. Place the client on their side
, which helps maintain an open airway and prevents aspiration. The other options are incorrect because inserting a tongue blade can cause airway obstruction, restraining movement can lead to injury, and moving the client during a seizure can worsen their condition. The nurse should stay with the patient, ensure a safe environment, and monitor the duration and characteristics of the seizure to provide appropriate post-seizure care.


2.

Given the following arterial blood gas results: pH 7.50, PaCO2 22 mmHg, HCO3 22 mEq/L, PaO2 42 mmHg, what condition is indicated by these values

  • Metabolic acidosis

  • Respiratory alkalosis

  • Metabolic alkalosis

  • Respiratory acidosis

Explanation

Correct Answer: B. Respiratory Alkalosis





Why the Correct Answer Is Respiratory Alkalosis:

Step 1: Determine if the pH is normal, acidic, or alkalotic.

pH = 7.50 (above normal range)Indicates alkalosis

Step 2: Identify if the cause is respiratory or metabolic.

PaCO₂ = 22 mmHg (low) → Since CO₂ is acidic, a low PaCO₂ suggests excessive CO₂ loss (which makes the blood more alkaline).

HCO₃⁻ = 22 mEq/L (normal) → Since bicarbonate (a base) is within the normal range, the cause is not metabolic.

Conclusion:

Alkalotic pH + Low PaCO₂ + Normal HCO₃⁻ = Respiratory Alkalosis

Why the Other Options Are Incorrect:

A. Metabolic Acidosis

Acidosis means the pH would be low (<7.35)
, but in this case, the pH is high (alkalotic)HCO₃⁻ is normal; if metabolic acidosis were present, bicarbonate would be low (<22 mEq/L).

C. Metabolic Alkalosis

In metabolic alkalosis, HCO₃⁻ would be elevated (>26 mEq/L)
. Here, HCO₃⁻ is normal (22 mEq/L), ruling out a metabolic cause.

D. Respiratory Acidosis

Respiratory acidosis occurs when PaCO₂ is high (>45 mmHg)
, leading to a low pH (<7.35). In this case, PaCO₂ is low (22 mmHg) and pH is high, which is the opposite of respiratory acidosis.

Additional Considerations:

The PaO₂ of 42 mmHg
is severely low, indicating hypoxemia

Common causes of respiratory alkalosis include:

Hyperventilation (due to anxiety, pain, fever, or hypoxia).

Pulmonary disorders (such as pulmonary embolism, pneumonia, or high-altitude sickness).

Mechanical ventilation set at high respiratory rates.

Summary:

This ABG result indicates respiratory alkalosis
, as shown by high pH, low PaCO₂, and normal HCO₃⁻. The low PaO₂ suggests the presence of hypoxemia, which might be causing the hyperventilation leading to CO₂ loss.


3.

A nurse at a rehabilitation center is planning care for a client who had a left hemispheric cerebrovascular accident (CVA) 3 weeks ago. Which of the following goals should the nurse include in the client's rehabilitation program

  • Establish the ability to communicate effectively.

  • Compensate for loss of depth perception.

  • Learn to control impulsive behavior.

  • Improve left-side motor function.

Explanation

Correct Answer: A. Establish the ability to communicate effectively.

Explanation:

A left hemispheric cerebrovascular accident (CVA) primarily affects the language centers
of the brain, such as Broca’s area (speech production) and Wernicke’s area (language comprehension). Clients with a left-sided stroke often experience aphasia (difficulty speaking or understanding language) and dysarthria (slurred speech). Therefore, re-establishing effective communication is a key rehabilitation goal.

Why the Other Options Are Incorrect:

B. Compensate for loss of depth perception

Right hemispheric strokes more commonly affect visual-spatial perception, including depth perception. A left hemispheric stroke primarily affects language and right-sided motor function rather than visual processing.

C. Learn to control impulsive behavior

Right hemispheric strokes tend to result in impulsive, poor judgment, and risk-taking behavior. Left-sided strokes typically cause cautious and slow behavior rather than impulsivity.

D. Improve left-side motor function

A left hemispheric stroke affects the right side of the body, causing right-sided weakness (hemiparesis) or paralysis (hemiplegia)
. Improving right-side motor function would be a more relevant goal.

Summary:

For a client with a left hemispheric stroke
, speech and language rehabilitation is crucial due to aphasia and other communication difficulties. Establishing effective communication should be a primary goal in their rehabilitation plan.


4.

A nurse is caring for a client who is 5 hr postoperative following a transurethral resection of the prostate (TURP). The nurse notes that the client's indwelling urinary catheter has not drained in the past hour. Which of the following actions should the nurse take first

  • Notify the provider.

  • Check the tubing for kinks.

  • Adjust the rate of the bladder irrigant.

  • Irrigate the catheter

Explanation

Correct Answer: B. Check the tubing for kinks.

Explanation:

The first action the nurse should take is to check the tubing for kinks or obstruction. A kinked or twisted catheter tube can block urine flow, leading to bladder distension and discomfort. This is the least invasive and quickest
action to restore drainage before considering other interventions.

Why the Other Options Are Incorrect:

A. Notify the provider.

This is incorrect as the first action. The nurse should assess the catheter tubing for kinks and other potential obstructions before escalating the issue to the provider. If troubleshooting measures do not resolve the issue, then the provider should be notified.

C. Adjust the rate of the bladder irrigant.

This is incorrect because adjusting the irrigation flow rate without first identifying the cause of the blockage can worsen the problem. If the tubing is kinked, increasing the irrigation flow will not resolve the obstruction. Proper assessment should come first

D. Irrigate the catheter.

This is incorrect as the first action. While irrigation may be necessary if there is a clot or blockage, it should not be done before assessing the tubing for external kinks or twists. Unnecessary irrigation can introduce bacteria and increase infection risk.

Summary:

The correct answer is B
, as checking for kinks is the simplest and least invasive way to restore urine flow. If the tubing is not kinked and the catheter remains blocked, further interventions such as irrigation or provider notification may be necessary.


5.

A nurse is teaching a client who has type 1 diabetes mellitus about exercise. Which of the following instructions should the nurse include

  • Examine your feet weekly.

  • Do not exercise if ketones are present in your urine.

  • Avoid eating for 2 hr before exercise.

  • Perform vigorous exercise when blood glucose is less than 100 mg/dL.

Explanation

The correct answer is: B) Do not exercise if ketones are present in your urine.

Explanation:

When managing type 1 diabetes mellitus, exercise can be beneficial but needs to be approached with caution, especially in certain situations. Here's why the selected option is correct and the others are not:
 If ketones are present in the urine, it may indicate that the body is not getting enough insulin and is breaking down fat for energy, which can lead to diabetic ketoacidosis (DKA). Exercise during this time can worsen the condition and increase the risk of complications, so it's important to avoid exercise until ketones are cleared from the urine.

Why the other options are incorrect:

Examine your feet weekly:

While foot care is extremely important for individuals with diabetes, the recommendation should be to examine your feet daily and report any changes or sores immediately. Weekly foot checks are not frequent enough to identify potential issues early.

Avoid eating for 2 hours before exercise:

This is not a recommended guideline for people with diabetes. Exercise can lower blood glucose levels, and it's important to have a source of carbohydrate available to prevent hypoglycemia, especially for people on insulin or other diabetes medications. It's generally advised to eat a balanced meal or snack before exercise if needed.

Perform vigorous exercise when blood glucose is less than 100 mg/dL:

Exercising when blood glucose is too low (hypoglycemia) can increase the risk of worsening hypoglycemia and lead to dangerous symptoms like dizziness, confusion, or even fainting. If blood glucose is less than 100 mg/dL, the client should consume carbohydrates before exercising, rather than engaging in vigorous exercise.

Summary:

​​​​​​​The most important instruction for a client with type 1 diabetes mellitus is to avoid exercise if ketones are present in the urine
, as exercise in this state can increase the risk of diabetic ketoacidosis (DKA).


6.

A nurse is documenting information in a computerized health record. Which of the following nursing actions jeopardizes client confidentiality

  • Preventing an unidentified health care worker from viewing a health record on the computer screen.

  • Using a computer terminal in a non-public area.

  • Logging out of the computer before leaving a terminal.

  • Sharing computer password with coworkers

Explanation

Correct Answer: Sharing computer password with coworkers.

Explanation:

Confidentiality in electronic health records (EHR) is crucial for protecting patient privacy and complying with regulations like the Health Insurance Portability and Accountability Act (HIPAA).
Sharing a computer password with coworkers violates hospital policies and legal guidelines, putting patient information at risk. Each healthcare worker should have individual login credentials to maintain accountability and data security.

Incorrect Answers & Rationale:

"Preventing an unidentified health care worker from viewing a health record on the computer screen."

Incorrect because this action supports client confidentiality. Healthcare workers should only access patient records if they are directly involved in the patient’s care. Allowing an unauthorized individual to view records would be a HIPAA violation.

"Using a computer terminal in a non-public area."

Incorrect because this helps protect confidentiality. Computer screens should be positioned away from public view to reduce the risk of unauthorized access.

"Logging out of the computer before leaving a terminal."

Incorrect because this is a correct and recommended action. Logging out prevents unauthorized users from accessing patient data if the terminal is left unattended.

Summary:

The correct answer is "Sharing computer password with coworkers"
because it jeopardizes patient confidentiality and violates security policies. The other actions promote patient privacy and data security, which are essential in maintaining ethical and legal nursing practices.


7.

A Native American is admitted to the hospital with a rash, cough, and fever. Which is the most important information for the nurse to gather from the nursing assessment

  • Employment status

  • Immunization history

  • Food preference

  • Use of Alcohol

Explanation

Correct Answer:  Immunization history

Explanation:

When a Native American client presents with symptoms like a rash, cough, and fever
, it is essential to consider potential infectious diseases that could be more prevalent or pose a higher risk in certain populations, such as tuberculosis (TB), which historically has had a significant impact on Native American communities. A proper immunization history will help the nurse identify whether the client is up to date on vaccinations, including the BCG vaccine for TB or other routine immunizations, and guide further diagnostic and treatment decisions.

Why the Other Options Are Less Important:

Employment status: While it may be relevant for understanding the client’s lifestyle or exposure risks, employment status does not directly impact the diagnosis or treatment of symptoms like rash, cough, and fever in the immediate context of this presentation.

Food preference: This could be important later, especially in relation to cultural sensitivity, nutrition, or dietary restrictions, but it does not directly relate to addressing the current symptoms of a rash, cough, and fever.

Use of alcohol: While alcohol use may impact the overall health of a person, such as contributing to liver disease or affecting immune function, it is not the most important factor to assess in relation to the acute presentation of symptoms like those described (rash, cough, and fever).

Summary:

The most important information to gather first is the immunization history
, as it can guide the nurse in identifying potential infections that are common in Native American populations, such as tuberculosis, and help determine appropriate interventions. The other options, while potentially useful later, are secondary in this acute assessment.


8.

A nurse is auscultating a client's heart sounds and hears an extra heart sound before what should be considered the first heart sound S1. The nurse should document this finding as which of the following heart sounds

  • A split second heart sound S2

  • The third heart sound (S3)

  • A friction rub

  • The fourth heart sound (S4)

Explanation

Correct Answer: The fourth heart sound (S4)

Explanation:

An S4 heart sound
occurs before the first heart sound (S1) and is often referred to as an atrial gallop. It is caused by atrial contraction pushing blood into a stiff or noncompliant ventricle and is typically associated with conditions such as hypertension, left ventricular hypertrophy, aortic stenosis, and myocardial ischemia. The sound occurs late in diastole, just before S1, and is best heard with the bell of the stethoscope over the apex of the heart.

Why the Other Options Are Incorrect

A split second heart sound (S2)

S2 splitting occurs after S1, not before it. A physiologic split S2 is heard during inspiration due to delayed closure of the pulmonary valve. A fixed split S2 can indicate atrial septal defect (ASD) or right bundle branch block (RBBB), but it does not occur before S1.

The third heart sound (S3)

S3 occurs after S2, during early diastole, and is known as a ventricular gallop. It is associated with heart failure, volume overload, or dilated cardiomyopathy. Unlike S4, which happens before S1, S3 occurs after S2.

A friction rub

A pericardial friction rub
is a high-pitched, scratchy sound caused by pericardial inflammation (e.g., pericarditis). It is not a heart sound like S1, S2, S3, or S4 and does not occur in a predictable phase of the cardiac cycle.

Summary

An S4 heart sound occurs just before S1 and is caused by atrial contraction against a stiff ventricle
. It is commonly found in hypertensive heart disease, aortic stenosis, and ischemic heart disease. Unlike S3 (which follows S2), an S4 sound is heard before S1 and suggests decreased ventricular compliance.


9.

A nurse is caring for an older adult client who has a urinary tract infection (UTI). Which of the following manifestations should the nurse identify as a finding specifically associated with this client

  • Low back pain

  • Urinary retention

  • Confusion

  • Incontinence

Explanation

The correct answer is C. Confusion.

Explanation

In older adult clients, a urinary tract infection (UTI) may not present with the typical symptoms seen in younger adults, such as dysuria (painful urination) or fever. Instead, older adults may exhibit more generalized or atypical symptoms, such as confusion
or altered mental status. This is often referred to as "delirium" associated with infections, and it can be one of the most common signs of a UTI in the elderly population. The infection may cause an inflammatory response that affects the central nervous system, leading to confusion, agitation, or disorientation.

why the other choices are incorrect:

A. Low back pain

Low back pain can occur with a UTI, especially if there is involvement of the kidneys (such as in pyelonephritis), but it is not specifically associated with UTIs in older adults. Older clients with a UTI may not always present with classic flank pain or low back pain.

B. Urinary retention

Urinary retention can occur with a UTI, especially if there is obstruction or a more complicated urinary tract issue. However, urinary retention is not a hallmark sign of UTI in older adults. More commonly, older adults with UTIs experience confusion or incontinence rather than urinary retention.

D. Incontinence

Incontinence can be a symptom of a UTI, particularly in older adults, but it is not as specific to UTI as confusion. Incontinence can also be caused by other factors, such as age-related changes, neurological disorders, or cognitive decline. Although incontinence may be a presenting symptom, it is not as distinctively associated with UTIs as confusion is.

Summary:

For older adult clients with urinary tract infections, confusion
is the manifestation that is most specifically associated with UTIs in this population. Due to age-related changes and potential coexisting conditions, UTIs in older adults often present with atypical symptoms, and confusion is one of the primary signs to look out for.


10.

A nurse in a provider's office is assessing a client who reports dyspnea and fatigue. Physical assessment reveals tachycardia and weak peripheral pulses. The nurse should recognize these findings as manifestations of which of the following conditions

  • Heart failure

  • Asthma

  • Aortic stenosis

  • Aortic valve regurgitation

Explanation

Correct Answer: Heart Failure

Explanation:

Heart failure is a condition where the heart cannot pump blood effectively
, leading to decreased oxygen delivery to tissues and fluid buildup. The client’s symptoms—dyspnea, fatigue, tachycardia, and weak peripheral pulses—are classic manifestations of heart failure, particularly left-sided heart failure. Key features include:

Dyspnea (Shortness of Breath): Due to fluid accumulation in the lungs (pulmonary congestion).

Fatigue: Caused by reduced cardiac output and decreased oxygen supply to muscles.

Tachycardia: The body compensates for poor circulation by increasing heart rate.

Weak Peripheral Pulses: Due to decreased cardiac output and poor perfusion to extremities.

Why the Other Options Are Incorrect:

Asthma

Incorrect because asthma is a respiratory disorder characterized by wheezing, chest tightness, and bronchospasmsNo mention of wheezing or acute respiratory distress in the scenario. Asthma does not typically cause weak peripheral pulses or tachycardia related to heart dysfunction

Aortic Stenosis

Incorrect because aortic stenosis causes dyspnea, fatigue, and weak pulses, but it is usually associated with syncope (fainting) and chest pain with exertion due to decreased blood flow. In severe cases, it leads to murmurs and narrow pulse pressure, which are not described in the scenario.

Aortic Valve Regurgitation

Incorrect because aortic regurgitation causes a bounding pulse, widened pulse pressure, and a water hammer pulse, which are not described in the scenario. While it can lead to heart failure over time, the symptoms in the scenario do not specifically suggest aortic regurgitation.

Summary:

The correct answer is heart failure because the client's dyspnea, fatigue, tachycardia, and weak peripheral pulses
indicate poor cardiac output and pulmonary congestion, hallmark signs of left-sided heart failure. Unlike asthma or aortic valve disorders, heart failure directly explains the combination of symptoms described.
