A nurse is caring for a client who reports a headache and has a history of a peptic ulcer. Which of the following medications should the nurse administer?

1. . Answer and explanation.

The correct answer is choice C, first-degree atrioventricular block.

This is because the PR interval is longer than normal, which indicates a delay in the conduction of electrical impulses from the atria to the ventricles through the AV node. A normal PR interval is 0.12 to 0.2 seconds, or 3 to 5 small squares on the EKG strip.

In this case, the PR interval is 0.35 seconds, which is more than 5 small squares.

Choice A is wrong because atrial fibrillation is a type of arrhythmia where the atria beat irregularly and rapidly, producing chaotic and variable P waves and an irregular ventricular response.

There is no constant PR interval in atrial fibrillation.

Choice B is wrong because complete heart block is a type of arrhythmia where there is no conduction of electrical impulses from the atria to the ventricles, resulting in independent and dissociated atrial and ventricular rhythms.

There are no consistent P waves or PR intervals in complete heart block.

Choice D is wrong because premature atrial complexes are extra beats that originate from the atria and interrupt the normal sinus rhythm.

They produce abnormal P waves that are different from the sinus P waves, and may have a shorter or longer PR interval depending on the timing of the impulse.

However, they do not cause a constant prolongation of the PR interval.

Choice A reason:

Determine previous coping skills used by the client is not appropriate. Assessing the client's previous coping skills is an essential step in the assessment phase of the therapeutic relationship, not specifically during the orientation phase. This information helps the nurse to understand the client's coping mechanisms and identify potential areas for improvement or support.

Choice B reason:

Facilitate the client's problem-solving skills is not appropriate the nurse may work on facilitating the client's problem-solving skills throughout the therapeutic relationship, including during the working phase. During this phase, the nurse and client collaborate to explore and address the client's concerns and challenges.

Choice Creason:

Assisting the client in expressing alternative behaviours is not appropriate. This action may also be part of the working phase, where the nurse helps the client explore alternative behaviours and coping strategies to address their issues and challenges.

Choice D reason:

The orientation phase is the initial stage of the therapeutic relationship where the nurse and the client get to know each other and establish the groundwork for their working relationship. During this phase, it is essential to clarify the roles and responsibilities of both the nurse and the client to ensure a clear understanding of each other's expectations.
