Nursing Elites

1. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding requires immediate intervention?

• A. Peaked T waves on the ECG
• B. Bradycardia
• C. Decreased deep tendon reflexes
• D. Muscle weakness

Correct answer: A

Rationale: Peaked T waves on the ECG are a critical finding in hyperkalemia as they indicate potential life-threatening cardiac arrhythmias. Immediate intervention is necessary to prevent cardiac complications such as ventricular tachycardia or fibrillation. Bradycardia, decreased deep tendon reflexes, and muscle weakness are not typically associated with hyperkalemia and do not pose the same level of immediate risk to the client's life.

2. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Prothrombin time (PT)
• C. Serum sodium level
• D. Hemoglobin level of 12 g/dl

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range to prevent both bleeding and clotting events. Choices B, C, and D are incorrect because while PT is used to monitor warfarin therapy, INR is a more precise indicator of therapeutic levels. Serum sodium level and hemoglobin level are not directly related to monitoring warfarin therapy.

3. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

4. After a third hospitalization 6 months ago, a client is admitted to the hospital with ascites and malnutrition. The client is drowsy but responding to verbal stimuli and reports recently spitting up blood. What assessment finding warrants immediate intervention by the nurse?

• A. Bruises on arms and legs
• B. Round and tight abdomen
• C. Pitting edema in lower legs
• D. Capillary refill of 8 seconds

Correct answer: D

Rationale: In this situation, the client's capillary refill of 8 seconds is the assessment finding that warrants immediate intervention by the nurse. A capillary refill greater than 3 to 5 seconds indicates poor perfusion, which could be a sign of inadequate circulation and oxygenation. Checking capillary refill is a quick and useful way to assess peripheral perfusion. Bruises on arms and legs may indicate a bleeding disorder but are not as urgent as addressing poor perfusion. A round and tight abdomen could suggest ascites, which is already known in this case. Pitting edema in lower legs is a common finding in malnutrition and ascites but does not require immediate intervention as poor capillary refill does.

5. A nurse plans to call the healthcare provider to report an 0600 serum potassium level of 2 mEq/L or mmol/L (SI), but the charge nurse tells the nurse that the healthcare provider does not like to receive early morning calls and will make rounds later in the morning. What action should the nurse take?

• A. Contact the healthcare provider immediately to report the laboratory value regardless of the advice.
• B. Document the finding and report it when the healthcare provider makes rounds.
• C. Notify the charge nurse that you are following the chain of command.
• D. Administer a potassium supplement and notify the provider later.

Correct answer: A

Rationale: A nurse should contact the healthcare provider immediately to report a critically low potassium level of 2 mEq/L. Potassium levels below the normal range can lead to life-threatening complications such as cardiac arrhythmias. Prompt notification is essential to ensure timely intervention and prevent harm to the patient. Option B is incorrect as delaying reporting such a critical value can jeopardize patient safety. Option C is not the priority in this situation; the focus should be on patient care. Option D is dangerous and inappropriate as administering a potassium supplement without healthcare provider's guidance can be harmful, especially with a critically low level.
