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. The nurse observes an unlicensed assistive personnel (UAP) using an alcohol-based gel hand cleaner before performing catheter care. The UAP rubs both hands thoroughly for 2 minutes while standing at the bedside. Which action should the nurse take?

• A. Encourage the UAP to remain in the client's room until the procedure is completed.
• B. Explain that the hand rub can be completed in less than 2 minutes.
• C. Inform the UAP that handwashing helps to promote better asepsis.
• D. Determine why the UAP was not wearing gloves in the client's room.

Correct answer: B

Rationale: The correct answer is B. Explaining that hand rubs can be effective with less time allows the UAP to perform the procedure more efficiently while maintaining asepsis. Choice A is incorrect because the UAP does not need to remain in the client's room until the procedure is completed. Choice C is incorrect as the UAP was using an alcohol-based gel hand cleaner, not handwashing. Choice D is incorrect as the scenario does not mention any issue with glove usage, so it is not relevant to the situation at hand.

3. After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?

• A. Slide the stethoscope across the sternum.
• B. Move the stethoscope to the mitral site.
• C. Listen with the bell at the same location.
• D. Observe the cardiac telemetry monitor.

Correct answer: C

Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.

4. Which assessment finding indicates to the nurse a client's readiness for pulmonary function tests?

• A. Expresses an understanding of the procedure.
• B. NPO for 6 hrs.
• C. No known drug allergies.
• D. Intravenous access intact.

Correct answer: A

Rationale: The correct answer is A: 'Expresses an understanding of the procedure.' This choice indicates that the client is mentally prepared for the pulmonary function tests, as understanding the procedure shows readiness and cooperation. Choices B, C, and D are incorrect. Choice B, 'NPO for 6 hrs,' pertains to fasting status and is not directly related to readiness for the test. Choice C, 'No known drug allergies,' is important information but does not specifically indicate readiness for pulmonary function tests. Choice D, 'Intravenous access intact,' is related to vascular access and not a direct indicator of readiness for the pulmonary function tests.

5. A client with a history of heart failure presents to the clinic with nausea, vomiting, yellow vision, and palpitations. Which finding is most important for the nurse to assess for this client?

• A. Assess distal pulses and signs of peripheral edema
• B. Determine the client's level of orientation and cognition
• C. Obtain a list of medications taken for cardiac history
• D. Ask the client about exposure to environmental heat

Correct answer: C

Rationale: The correct answer is to obtain a list of medications taken for cardiac history. The client's presentation is indicative of digitalis toxicity, commonly associated with medications like digoxin (Lanoxin) used in heart failure treatment. Understanding the client's medication history, particularly the use of digoxin, is crucial in confirming and managing digitalis toxicity. Assessing distal pulses and signs of peripheral edema (Choice A) may be relevant in heart failure but are not the priority in this case. Determining the client's level of orientation and cognition (Choice B) and asking about exposure to environmental heat (Choice D) are not directly related to the client's current symptoms and are less pertinent in this scenario.
