ATI NUR 130 Final Exam

Correct Answer: Utilize SBAR to notify the primary health care provider.

Correct Answer Explanation:

Utilize SBAR to notify the primary health care provider.

This is the most appropriate first action because the patient is showing early signs of a surgical site infection (SSI): redness, purulent drainage, tenderness, mild fever (100.5° F), and an elevated white blood cell count (WBC 10,500/mm³). Using SBAR (Situation, Background, Assessment, Recommendation) allows the nurse to communicate the patient's condition clearly and efficiently to the provider so that timely medical intervention (e.g., wound culture, antibiotic therapy) can be initiated. Prompt reporting is crucial in preventing worsening infection.

Explanation of Incorrect Options:

Plan to change the surgical dressing during the shift.

Incorrect. While dressing changes are important, planning alone without notifying the provider delays potential treatment. Infection signs must be addressed immediately, not simply managed passively.

Reevaluate the temperature and white blood cell count in 4 hours.

Incorrect. Monitoring is useful, but waiting 4 hours before acting could allow the infection to progress. The signs of infection are already present and warrant immediate attention.

Check to see what solution was used for skin preparation in surgery.

Incorrect. Although a reaction to Betadine (povidone-iodine) is possible, the current signs—purulent drainage and fever—suggest infection rather than an allergic reaction. The priority is treating the current clinical findings, not reviewing surgical prep details first.

Summary:

The patient has clear indicators of a possible surgical site infection, which requires timely reporting to the healthcare provider for further diagnostic and therapeutic actions. While dressing changes, ongoing monitoring, and reviewing prep solutions may be appropriate secondary actions, the first priority is to notify the provider using SBAR communication.

Correct Answer: Immobility

Detailed Explanation of the Correct Answer:

Immobility is the primary factor contributing to the development of pressure injuries in patients with impaired sensory perception. When patients cannot feel discomfort or pain, they may not recognize the need to change position. As a result, they remain in one position for too long, leading to sustained pressure on certain areas of the body, particularly over bony prominences. This prolonged pressure reduces capillary blood flow, causing ischemia, tissue damage, and eventually pressure injuries.

Patients with conditions such as spinal cord injuries, advanced diabetes with neuropathy, or stroke often have decreased sensation and rely on caregivers or regular repositioning to prevent skin breakdown.

Explanation of Incorrect Options:

Increased Moisture – While moisture can weaken skin integrity and contribute to maceration, it is not the primary factor in pressure injury development related to impaired sensory perception. It is more directly associated with incontinence-related skin issues.

Friction and Shear – Friction and shear are mechanical forces that can exacerbate skin breakdown, especially during repositioning or movement. However, they are secondary factors and not specifically tied to sensory perception loss.

Decreased Tissue Perfusion – This is an important contributing factor in pressure injury development overall, but in the context of impaired sensory perception, immobility is more directly linked, as the patient cannot feel the need to move or shift pressure points.

Summary:

Patients with impaired sensory perception are at greatest risk of developing pressure injuries due to immobility, which leads to unrelieved pressure on the skin. While other factors like moisture, friction, and perfusion affect skin integrity, immobility is the primary concern in this specific context.

Correct Answer: An infectious disease like pneumonia may not pose a risk to others.

Correct Answer Explanation:

An infectious disease like pneumonia may not pose a risk to others.

This is the correct statement. Pneumonia can be caused by a variety of pathogens, including bacteria, viruses, and fungi. Not all forms of pneumonia are contagious. For example, aspiration pneumonia (caused by inhalation of food, stomach acid, or saliva into the lungs) is not infectious. Some bacterial or viral pneumonias can be contagious, but not every case of pneumonia presents a transmission risk. Therefore, standard precautions are typically sufficient unless a highly infectious organism is identified.

Explanation of Incorrect Options:

We need to isolate the patient in a private negative-pressure room.

Incorrect. Negative-pressure rooms are used for airborne precautions, such as for tuberculosis or measles, not for typical pneumonia. Pneumonia usually requires only standard precautions unless caused by a specific airborne pathogen.

Clinical signs and symptoms are not present in pneumonia.

Incorrect. Pneumonia does present with clinical signs and symptoms, such as cough, fever, chills, difficulty breathing, chest pain, and abnormal lung sounds. Saying otherwise reflects a misunderstanding.

The patient will not be able to return home.

Incorrect. Many patients with pneumonia, especially mild or community-acquired cases, can and do recover at home, often with oral antibiotics and supportive care. Hospitalization is needed only for moderate to severe cases or for patients with significant comorbidities.

Summary:

The new nurse correctly understands that not all pneumonia cases are infectious, and therefore may not pose a risk to others, making option a the best choice. Other statements reflect misunderstandings about transmission, symptoms, and discharge planning.

Correct Answer: Leave the catheter in the vagina as a landmark for insertion of a new, sterile catheter.

Labeled and Detailed Explanation for the Correct Answer:

Leave the catheter in the vagina as a landmark for insertion of a new, sterile catheter. – When a catheter is mistakenly inserted into the vagina instead of the urethra, the best practice is to leave it in place. This acts as a landmark to avoid repeating the error. The nurse can then use a new sterile catheter and successfully insert it into the urethral meatus. This prevents repeated contamination and ensures accurate placement with reduced risk of infection or trauma.

Explanations for Each Incorrect Option:

Throw the catheter away and begin again. – Simply discarding the catheter without using it as a landmark may lead to repeating the same mistake. It is not the most efficient or effective solution in this context.

Fill the balloon with the recommended sterile water. – Never inflate the balloon unless urine return is seen, confirming the catheter is in the bladder. Inflating the balloon in the vagina can cause tissue trauma.

Remove the catheter, wipe with alcohol, and reinsert after lubrication. – Reusing a catheter is not sterile and increases the risk of infection. Once a catheter has been inserted, it is considered contaminated and must be discarded.

Summary:

If a catheter is accidentally inserted into the vagina, the nurse should leave it in place as a visual guide and then insert a new sterile catheter into the correct site. This approach helps prevent repetition of the error and minimizes infection risk. Never reuse or inflate a catheter unless proper placement in the bladder is confirmed.

Correct Answer: Fluid loss and temperature regulation issues

Explanation of Correct Answer:

Fluid loss and temperature regulation issues

Infants have thinner, more permeable skin than adults, which compromises the skin’s ability to act as a strong barrier. This makes them more prone to:

Increased fluid loss due to greater transepidermal water loss (TEWL)

Difficulty maintaining body temperature, since they have less subcutaneous fat and underdeveloped thermoregulatory systems

Higher susceptibility to irritants and infections through the skin

Because of these factors, infants require careful environmental temperature regulation and skin care to prevent dehydration and hypothermia.

Explanation of Incorrect Answers:

Wrinkles

Incorrect. Wrinkles are associated with aging and loss of skin elasticity, not infant skin. Infant skin is generally smooth and well-hydrated.

Allergic reactions

Incorrect. While infants may be more sensitive to irritants, thinner skin does not directly cause allergic reactions. Allergies are primarily linked to immune system responses, although the skin’s permeability can allow easier access for potential allergens.

Acne

Incorrect. Acne is more common during puberty due to hormonal changes, not due to the thinness of infant skin. Some newborns may have neonatal acne, but it’s not due to permeability of the skin.

Summary:

Infants' thinner and more permeable skin makes them especially prone to fluid loss and temperature instability, requiring careful skin care and environmental control to maintain homeostasis.

Correct Answer: Hemoglobin

Detailed Explanation of the Correct Answer:

Hemoglobin is a critical lab value to assess when evaluating risk for pressure injuries because it reflects the blood’s oxygen-carrying capacity. Adequate tissue oxygenation is essential for maintaining healthy skin and supporting wound healing. Low hemoglobin levels (anemia) can lead to poor tissue perfusion, which increases the risk of tissue breakdown and pressure injuries. Therefore, monitoring hemoglobin helps the nurse evaluate if the patient has sufficient oxygen delivery to tissues to maintain skin integrity and support repair processes.

Explanation of Incorrect Options:

Xerosis – This refers to abnormally dry skin, not a laboratory study. While xerosis can affect skin health, it is not a lab value the nurse would check.

Suspensions – This is a form of medication delivery, not a lab test. It has no relevance to lab evaluation for pressure injury risk.

Hydrophilic – This term refers to substances that attract water, and it is not a lab value. It is unrelated to assessing pressure injury risk via laboratory studies.

Summary:

When evaluating risk for pressure injuries, the nurse should check hemoglobin to ensure adequate oxygenation and perfusion of tissues. Low hemoglobin levels can compromise skin integrity, increasing the patient’s risk for developing pressure ulcers. The other options listed are not laboratory values and do not assist in this type of assessment.

Correct Answer: Testing the patient and offering treatment to the nurse

Detailed Explanation of the Correct Answer:

Testing the patient and offering treatment to the nurse

This is the most appropriate and essential step following a blood exposure injury, such as a cut from a used scalpel, which poses a significant risk for transmission of bloodborne pathogens (e.g., HIV, Hepatitis B, Hepatitis C). The protocol typically involves:

Source patient testing, with informed consent, to determine their infection status.

Immediate medical evaluation of the exposed nurse, including:

Documentation of the exposure

Baseline blood tests

Counseling about the risks

Post-exposure prophylaxis (PEP) if indicated (especially for HIV or HBV)

Follow-up testing for the nurse over a period of weeks to months, depending on risk.

This process ensures prompt intervention and reduces the risk of infection following occupational exposure.

Detailed Explanation of Incorrect Options:

Placing the scalpel in a needle safe container

While it’s good practice to dispose of sharps in a proper sharps container, this is a routine precautionary action and not the primary or required post-exposure step after a nurse has already been injured by the scalpel.

Removing sterile gloves and disposing of in kick bucket

Disposing of gloves does not address the exposure or injury. Additionally, kick buckets are not designated for biohazard disposal. This response is inadequate and unsafe for managing blood exposure.

Providing a medical evaluation of the nurse to the manager

This is an incomplete and inaccurate response. The nurse should receive a medical evaluation, but this is not something “provided to the manager.” Instead, the nurse should be medically assessed by a licensed provider and the exposure reported to the manager as part of the incident report, but the primary concern is the nurse’s health and treatment, not managerial communication.

Summary:

When a nurse sustains a scalpel injury with blood exposure, the correct process involves testing the patient (with consent) and offering appropriate treatment and evaluation to the nurse. This is essential to manage infection risk, start any necessary prophylaxis, and ensure the nurse's safety and health.

Correct Answer: To maintain positive nitrogen balance and prevent malnutrition

Detailed Explanation of the Correct Answer:

Providing adequate carbohydrates, proteins, fats, vitamins, and minerals ensures that the body has the necessary nutrients to repair tissue, maintain skin integrity, and support immune function. Protein is particularly vital for maintaining a positive nitrogen balance, which reflects the body's ability to build and repair tissues. A positive nitrogen balance is essential in healing and maintaining healthy skin, especially in individuals at risk for or currently experiencing pressure injuries. Proper nutrition also helps prevent malnutrition, which is a major risk factor for delayed wound healing and increased susceptibility to pressure injuries.

Explanation of Incorrect Options:

To increase friction and shear – Adequate nutrition has no relation to friction or shear forces. Friction and shear are mechanical forces, not influenced by diet.

To reduce mobility and activity – Nutrition does not aim to reduce mobility. In fact, good nutrition can support energy levels and activity, which are beneficial in preventing pressure injuries.

To cause anemia – The purpose of adequate nutrition is the opposite of this. It prevents anemia by supplying essential vitamins like iron, B12, and folate, which are important for healthy red blood cell production.

Summary:

Adequate nutrition is crucial in pressure injury prevention because it helps maintain a positive nitrogen balance, supports tissue repair, strengthens skin integrity, and prevents malnutrition. It does not contribute to mechanical damage, reduced activity, or anemia.

Correct Answers:

Observations of wound healing

Daily blood pressure measurements

Findings of respiratory rate and depth

 Patient's subjective report of feelings about a new diagnosis of cancer

Detailed Explanation of Each Correct Answer:

Observations of wound healing

This is an objective evaluative measure. The nurse visually examines the wound to assess whether the care plan is effective in promoting healing.

Daily blood pressure measurements

This is a quantitative, objective measure used to evaluate whether interventions (e.g., medication, lifestyle changes) are helping control blood pressure.

Findings of respiratory rate and depth

This is another objective assessment that helps determine the effectiveness of respiratory interventions such as breathing treatments or oxygen therapy.

Patient's subjective report of feelings about a new diagnosis of cancer

Subjective data—what the patient says or feels—is an important evaluative measure when assessing emotional and psychological responses to care, especially for new diagnoses.

Why the Incorrect Option Is Wrong:

Completion of nursing interventions

This reflects nursing action, not patient response. While it’s important to document what was done, evaluation focuses on how the patient responded to the care provided—not whether tasks were completed.

Summary:

Evaluative measures focus on the patient's response to care, both objective (e.g., wound healing, vital signs) and subjective (e.g., emotional responses). The correct evaluative measures are a, b, c, and e.
