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. 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.

3. Before preparing a client for the first surgical case of the day, a part-time scrub nurse asks the circulating nurse if a 3-minute surgical hand scrub is adequate preparation for this client. Which response should the circulating nurse provide?

• A. Ask a more experienced nurse to perform that scrub since it is the first time of the day
• B. Validate the nurse is implementing the OR policy for surgical hand scrub
• C. Inform the nurse that hand scrubs should be 3 minutes between cases.
• D. Direct the nurse to continue the surgical hand scrub for a 5-minute duration.

Correct answer: D

Rationale: The correct answer is to direct the nurse to continue the surgical hand scrub for a 5-minute duration. Surgical hand scrubs should last for 5 to 10 minutes, ensuring thorough cleaning and disinfection. Choice A is incorrect because the nurse should be guided to complete the scrub properly rather than having someone else do it. Choice B is incorrect as it does not address the duration of the hand scrub. Choice C is incorrect as it suggests a 3-minute hand scrub is sufficient, which is inadequate for proper preparation before surgery.

4. When obtaining a rectal temperature with an electronic thermometer, which action is most important for the nurse to perform?

• A. Hold the thermometer in place.
• B. Place the disposable pad under the buttocks.
• C. Instruct the client to breathe deeply.
• D. Return the probe to the charger.

Correct answer: A

Rationale: When obtaining a rectal temperature with an electronic thermometer, holding the thermometer in place is crucial. This action ensures accurate temperature measurement and prevents injury to the client. Option B, placing a disposable pad under the buttocks, is not the most important action; it may enhance comfort but does not impact the accuracy of the temperature reading. Option C, instructing the client to breathe deeply, is irrelevant to obtaining a rectal temperature. Option D, returning the probe to the charger, is an incorrect action after temperature measurement.

5. 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.
