HESI Fundamentals

Correct Answer: Document in the medical record that these normal findings are expected outcomes

Explanation:

The client's urine output, BUN, and serum potassium levels are within normal limits, and the IV infusion is providing adequate hydration and potassium replacement. These are expected outcomes for a client who has been NPO and receiving maintenance fluids.

Urine output: 400 mL in 8 hours (within the normal range of 30-50 mL/hour).

BUN (Blood Urea Nitrogen): 15 mg/dL (normal range: 7-20 mg/dL), indicating normal kidney function and adequate hydration.

Serum potassium: 3.7 mEq/L (normal range: 3.5-5.0 mEq/L), which is within normal limits and reflects appropriate potassium replacement.

Since all parameters are normal and there are no signs of complications, the appropriate nursing action is to document these findings as expected outcomes.

Why the Other Options Are Incorrect:

Notify HCP and request to change the IV infusion to hypertonic D10W:

 There is no indication of hypoglycemia or nutritional deficits requiring hypertonic fluids like D10W. The current isotonic fluid is sufficient for hydration and potassium replacement.

Decrease in the infusion rate of the current IV and report to the HCP:

 The IV rate is appropriate for maintenance fluid therapy. Reducing the rate may decrease urine output and lead to dehydration.

Obtain potassium chloride 20 mEq in anticipation of a prescription to add to the current IV:

 The serum potassium level (3.7 mEq/L) is within normal limits, so additional potassium is not needed. Over-supplementation can cause hyperkalemia, which can be dangerous.

Summary:

The correct answer is to document in the medical record that these normal findings are expected outcomes because all lab values and clinical parameters are within normal limits, reflecting appropriate hydration and electrolyte balance.

Correct Answer. There will be no judgment against the nurse, whose actions were protected under the Good Samaritan Act.

Explanation:

This is the correct answer because the Good Samaritan Act protects individuals who provide emergency assistance at the scene of an accident from liability, as long as their actions are reasonable and performed in good faith. The nurse’s decision to apply pressure to the bleeding wound is consistent with basic life-saving measures. Since the nurse acted without gross negligence or willful misconduct, the court is unlikely to hold the nurse responsible for the amputation. The law encourages bystanders, including healthcare professionals, to assist in emergencies without fear of legal repercussions if their actions meet reasonable care standards.

Why the Other Options Are Incorrect:

 The Patient's Bill of Rights protects clients from malicious intents, so the nurse could lose the case:

This is incorrect because the Patient’s Bill of Rights primarily applies to hospital or clinical settings and protects clients’ rights to informed consent, confidentiality, and quality care. It does not apply to emergency situations covered by the Good Samaritan Act, especially when no malicious intent or gross negligence is present.

The lawsuit may be settled out of court, but the nurse's license is likely to be revoked:

This is incorrect because the nurse acted appropriately within the scope of emergency care. There is no evidence of malpractice or a breach of professional standards that would warrant revoking the nurse’s license. The Good Samaritan Act provides legal protection as long as care is provided in good faith without reckless behavior.

The client will win because the four elements of negligence (duty, breach, causation, and damages) can be proved:

This is incorrect because not all four elements of negligence can be established. While there was a duty to provide care and an injury (amputation), there is no evidence that the nurse breached the standard of care or that the nurse’s actions directly caused the injury. Applying pressure to a bleeding wound is a reasonable action to prevent further harm, not an act of negligence.

Summary:

The correct answer is that there will be no judgment against the nurse due to protection under the Good Samaritan Act. This law shields those who provide emergency aid from legal liability if their actions are reasonable and performed in good faith. The other options are incorrect because the Patient's Bill of Rights does not apply in this context, there is no basis for revoking the nurse’s license, and the elements of negligence cannot be fully established.

Correct Answer:Loosen the right wrist restraint.

Explanation:

This is the correct answer because blue fingers (cyanosis) indicate impaired circulation to the hand, which may be caused by the restraint being too tight. The priority action is to loosen the restraint immediately to restore blood flow and prevent tissue damage or permanent injury. According to safety guidelines, restraints should be applied snugly but not too tightly, allowing two fingers to fit between the restraint and the client’s skin. Prompt intervention is critical to prevent further circulatory compromise.

Why the Other Options Are Incorrect:

Apply a pulse oximeter to the right hand:

This is incorrect because while a pulse oximeter may provide information about oxygen saturation, it does not address the immediate concern of circulation impairment. The nurse must relieve the pressure from the restraint first before assessing oxygen levels to prevent further harm.

Compare hand color bilaterally:

This is incorrect because while comparing the color of both hands can provide useful baseline information, it does not resolve the immediate problem. The priority is to loosen the restraint to restore blood flow, as delaying this intervention could lead to tissue ischemia or necrosis.

Palpate the right radial pulse:

This is incorrect because although checking the radial pulse can confirm circulation, it does not address the primary issue. If blood flow is compromised, loosening the restraint is the most urgent action. Assessment should follow intervention, not delay it.

Summary:

When a client’s fingers are blue due to a wrist restraint, the first action is to loosen the restraint to restore blood flow and prevent tissue damage. While further assessments (like checking oxygen saturation, comparing color, or palpating the pulse) are important, they should only occur after circulation is immediately relieved. Prompt intervention prevents serious complications such as nerve damage or necrosis.

Correct Answer:  Battery.

Explanation:

Battery is the unlawful or unauthorized touching of another person without their consent, even if the act is intended to help. In this case, the client presented a signed living will with a Do Not Resuscitate (DNR) order, which clearly indicates that they do not want life-saving measures like cardiopulmonary resuscitation (CPR). By performing CPR, the nurse acted against the client's expressed legal wishes, which constitutes battery.

Why the Other Options Are Incorrect:

Assault:

Assault refers to threatening or causing the fear of physical harm without actually making physical contact. Since the nurse performed CPR, which involved actual physical contact, this would be classified as battery, not assault.

Malpractice:

Malpractice involves negligence or a failure to follow professional standards that results in harm to the patient. In this case, the nurse performed CPR, which is an active violation of the client's expressed legal directive, making battery the more appropriate charge.

False imprisonment:

False imprisonment occurs when someone is restrained or held against their will without legal justification. Performing CPR does not involve restricting the client’s movement, so this charge does not apply.

Summary:

The correct legal issue is Battery because the nurse performed unauthorized physical contact by administering CPR despite the client’s DNR status. This action violates the client’s legal right to refuse life-saving interventions as outlined in their living will.

Correct Answer: High risk for infection.

This nursing diagnosis has the highest priority because indwelling urinary catheters significantly increase the client's risk for developing a urinary tract infection (UTI). Catheter-associated urinary tract infections (CAUTIs) are one of the most common healthcare-associated infections and can lead to serious complications, including sepsis if not properly managed. The catheter provides a direct pathway for bacteria to enter the bladder, making infection prevention the primary concern. When caring for a client with an indwelling catheter, the nurse must prioritize interventions to reduce infection risk, such as maintaining a closed drainage system, using sterile technique during insertion, and performing regular hygiene. Because infection poses immediate and potentially life-threatening risks, it takes precedence over the other diagnoses.

Why the other options are incorrect:

Self-care deficit

While a client with an indwelling catheter may have difficulty performing personal hygiene or catheter care independently, this is not the highest priority. This diagnosis focuses on the client’s inability to complete self-care tasks, which is important but does not pose the immediate risk to physical health that infection does.

 Functional incontinence

Functional incontinence refers to involuntary urine loss due to mobility issues, cognitive impairment, or environmental barriers. However, an indwelling catheter bypasses the normal bladder function, making this diagnosis irrelevant while the catheter is in place. Managing infection risk is more urgent.

 Fluid volume deficit

Although monitoring fluid balance is essential for clients with urinary catheters, the presence of the catheter typically allows for accurate measurement of urine output. Unless there is evidence of dehydration, this diagnosis is not the most pressing concern. Preventing infection remains the primary focus.

Summary:

The most urgent nursing diagnosis for a client with an indwelling urinary catheter is high risk for infection. This diagnosis is prioritized due to the increased likelihood of developing a urinary tract infection and the potential for serious complications. While other diagnoses address important aspects of care, preventing infection is the immediate priority to protect the client’s health and safety.

Correct Answer: Gently lower the client to the floor.

Explanation:

When a client starts to fall, the nurse's first priority is to prevent injury. The best action in this situation is to gently lower the client to the floor to minimize the risk of injury from the fall. The nurse should attempt to control the fall to prevent any harm to the client, ensuring that the client is not injured during the process.

Why the other options are incorrect:

 Check the client's carotid pulse: Checking the pulse may be necessary after the fall, but it is not the first priority. The immediate priority is to prevent further harm by lowering the client safely to the floor. Once the client is safely on the floor, the nurse can check the pulse and assess for any other signs of injury or distress.

Encourage the client to get to the toilet: In this situation, the client is reporting feeling faint, which indicates that the client is at risk of falling. Encouraging the client to continue to the toilet would increase the risk of injury and is not appropriate. The nurse should instead focus on safely managing the client’s current condition and preventing the fall.

In a loud voice, call for help: While calling for help is important in some situations, the priority action when a client is about to fall is to ensure their safety first. The nurse should focus on preventing the fall by gently lowering the client to the floor before calling for assistance if needed. Once the client is safe, the nurse can call for help or additional support if required.

Summary:

The priority action when a client starts to fall is to gently lower the client to the floor. This action minimizes the risk of injury and ensures that the client’s safety is prioritized. After the fall, the nurse can assess the client's condition and call for help if necessary.

Correct Answer:  Observe the appearance of the skin under the ice pack.

Explanation:

The nurse’s first action should be to assess the skin under the ice pack to ensure there is no frostbite, tissue damage, or other adverse effects from direct contact with ice. Prolonged or direct exposure to ice can cause cold injuries such as frostbite, so it is crucial to first assess the skin condition before taking any further action.

Why the other options are incorrect:

 Instruct the client regarding the need for the covering:

While educating the client is important, the priority is to assess the skin for any damage before instructing the client on the proper use of the ice pack. The skin condition should be evaluated to ensure that further injury has not occurred.

Reapply the covering after filling with fresh ice:

Reapplying the ice pack with fresh ice is not appropriate until the skin is assessed. If the skin has been damaged or frostbitten, reapplying the ice could worsen the situation. First, the skin should be inspected.

Ask the client how long the ice was applied to the skin:

While it is helpful to know how long the ice has been applied, the immediate priority is to assess the skin for any visible damage before deciding on the next steps. The duration of the ice application can be determined after ensuring the skin is intact.

Summary:

The first priority in this situation is to observe the skin for any damage or adverse effects caused by the ice pack. Once the skin condition is assessed, appropriate action, such as reapplying the ice correctly or providing further instruction to the client, can be taken.

Correct Answer: During the inhalation

Explanation:

The correct technique for using an inhaler involves administering the medication during inhalation to ensure the medication reaches the lungs effectively. This allows the aerosolized medication to be carried deep into the airways, where it can exert its therapeutic effects. Proper inhaler use enhances medication absorption and improves outcomes for conditions like asthma or chronic obstructive pulmonary disease (COPD)

Steps for Correct Inhaler Use:

Shake the inhaler (if required).

Exhale fully to empty the lungs.

Position the inhaler correctly (either in the mouth or a short distance from it, depending on the type).

Inhale slowly and deeply while pressing the inhaler to release the medication.

Hold the breath for 10 seconds (or as long as comfortable) to allow the medication to settle in the lungs.

Exhale slowly and, if needed, wait 1 minute before taking a second puff.

Why the other options are incorrect:

 Immediately after exhalation:

This is incorrect because if the medication is delivered after exhaling, there is no airflow to carry the medication into the lungs. It would be wasted or remain in the mouth and throat, reducing its effectiveness.

At the end of three inhalers:

This is incorrect because it is unsafe and ineffective to wait until the end of three puffs before inhaling the medication. Each puff should be individually inhaled and spaced by at least 1 minute to ensure full delivery and prevent overdosing or ineffective treatment.

Immediately after inhalation:

This is incorrect because the medication must be released during the inhalation to ensure it is drawn deep into the lungs. Delivering the medication after inhaling would result in the loss of most of the medication, making the dose ineffective.

Summary:

The client should administer the inhaler-delivered medication during inhalation to ensure the medication reaches the lungs effectively. Proper inhaler technique is crucial

Correct Answer: B) Inflate blood pressure cuff to 120 mm Hg 

When obtaining a systolic blood pressure by palpation, the nurse inflates the cuff until the radial pulse is no longer palpable — this point estimates the systolic pressure. However, the cuff should be inflated an additional 30 mm Hg beyond the point where the pulse disappears to ensure an accurate reading and avoid underestimating the systolic pressure. 

Since the pulse disappeared at 90 mm Hg, the cuff should be inflated to 120 mm Hg (90 + 30). Releasing the valve immediately would give an inaccurate reading. Documenting the absence of the radial pulse is incorrect — this is an expected and normal part of the palpation technique. Recording 90 mm Hg as the systolic pressure at this point would be premature and inaccurate.
