A nurse is reviewing a client's cardiac rhythm strips and notes a constant P-R interval of
0.35 seconds. Which of the following dysrhythmias is the client displaying?
Premature atrial complexes
Complete heart block
Atrial fibrillation
First-degree atrioventricular block
The Correct Answer is D
A. Incorrect. Premature atrial complexes do not typically affect the P-R interval. They are characterized by an early P-wave followed by a QRS complex.
B. Incorrect. Complete heart block is characterized by a dissociation between the P-waves and QRS complexes, resulting in no relationship between atrial and ventricular activity.
C. Incorrect. Atrial fibrillation is characterized by chaotic and irregular atrial activity without distinct P-waves, making the P-R interval irrelevant.
D. Correct. In first-degree atrioventricular block, the P-R interval is prolonged beyond the normal range of 0.12-0.20 seconds. A constant P-R interval of 0.35 seconds indicates a first- degree atrioventricular block.

Correct Answer is A
Explanation
The correct answer is Choice A.
Choice A rationale: “What are the voices telling you?” This is the priority response because it directly addresses the client’s immediate concern. The nurse is acknowledging the client’s experience and seeking to understand more about it. This can help the nurse assess the potential for harm to the client or others, as the voices may be instructing the client to engage in dangerous behaviors.
Choice B rationale: “Have you taken your medication today?” While medication adherence is important in managing schizophrenia, this response does not address the client’s immediate concern about hearing voices. It may also come across as dismissive of the client’s experience.
Choice C rationale: “I realize the voices are real to you, but I don’t hear anything.” This response validates the client’s experience, but it does not gather further information about what the voices are saying, which is crucial for assessing safety.
Choice D rationale: “How long have you been hearing the voices?” While this question is relevant for understanding the client’s history and the progression of their illness, it is not the priority response. The immediate concern should be what the voices are saying to assess for potential harm.
Correct Answer is C
Explanation
A. Incorrect. Urination is not directly related to the evaluation of the effectiveness of a paracentesis procedure.
B. Incorrect. Checking serum albumin levels may be important in managing ascites, but it is not a direct measure of the immediate effectiveness of the paracentesis.
C. Correct. Monitoring the client's weight is a common way to assess the effectiveness of a paracentesis, as the procedure aims to remove excess abdominal fluid (ascites), which can lead to a reduction in body weight.
D. Incorrect. Examining for leakage at the site of the procedure is important for safety but does not directly reflect the effectiveness of the paracentesis.
