Nursing Elites

1. 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.

2. A healthcare provider is assessing a client with a history of hypertension who is currently taking a diuretic. Which assessment finding is most important to report to the healthcare provider?

• A. Potassium level of 3.2 mEq/L
• B. Blood pressure of 148/90 mmHg
• C. Pulse rate of 62 beats per minute
• D. Blood glucose level of 130 mg/dl

Correct answer: A

Rationale: A potassium level of 3.2 mEq/L is low and places the client at risk for cardiac arrhythmias, requiring immediate intervention. Hypokalemia can result from diuretic use and can lead to serious complications such as irregular heart rhythms. Monitoring and correcting potassium levels are crucial in preventing adverse cardiac events. The other options, though important, do not pose an immediate life-threatening risk compared to the low potassium level.

3. The healthcare provider explains through an interpreter the risks and benefits of a scheduled surgical procedure to a non-English speaking female client. The client gives verbal consent, and the healthcare provider leaves, instructing the nurse to witness the signature on the consent form. The client and the interpreter then speak together in the foreign language for an additional 2 minutes until the interpreter concludes, 'She says it is OK.' What action should the nurse take next?

• A. Ask for a full explanation from the interpreter of the witnessed discussion.
• B. Have the client sign the consent form.
• C. Document the conversation and witness the consent.
• D. Ask the client directly if she has any questions.

Correct answer: A

Rationale: The correct action for the nurse to take next is to ask for a full explanation from the interpreter of the witnessed discussion. Verbal consent is not sufficient; it is crucial to ensure that the client fully comprehends the risks and benefits of the surgical procedure. By asking the interpreter to provide a detailed explanation of the discussion, the nurse can confirm that the client has given informed consent. Having the client sign the consent form (Choice B) without ensuring complete understanding may lead to potential misunderstandings. Documenting the conversation and witnessing the consent (Choice C) is not enough to guarantee the client's comprehension. Asking the client directly if she has any questions (Choice D) may not be effective if language barriers persist.

4. After multiple attempts to stop drinking, an adult male is admitted to the medical intensive care unit (MICU) with delirium tremens. He is tachycardic, diaphoretic, restless, and disoriented. Which finding indicates a life-threatening condition?

• A. Widening QRS complexes and flat T waves
• B. Tachycardia and elevated blood pressure
• C. Restlessness and anxiety
• D. Diaphoresis and dehydration

Correct answer: A

Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.

5. A female client has been taking a high dose of prednisone, a corticosteroid, for several months. After stopping the medication abruptly, the client reports feeling 'very tired'. Which nursing intervention is most important for the nurse to implement?

• A. Measure vital signs
• B. Auscultate breath sounds
• C. Palpate the abdomen
• D. Observe the skin for bruising

Correct answer: A

Rationale: The correct answer is to measure vital signs. Abrupt withdrawal of exogenous corticosteroids can precipitate adrenal insufficiency, potentially leading to shock. Monitoring vital signs is crucial in identifying any signs of adrenal insufficiency, such as hypotension or tachycardia. Auscultating breath sounds (choice B) may be important in other situations, such as respiratory conditions, but it is not the priority in this case. Palpating the abdomen (choice C) and observing the skin for bruising (choice D) are not directly related to the potential complications of corticosteroid withdrawal and adrenal insufficiency.
