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

Answer and Explanation

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 ["C","D","G"]

Explanation

Choice A reason:

"Try using an abdominal support belt". This statement is incorrect. There is no indication or relevance for using an abdominal support belt based on the vital signs and weight provided. This statement is not appropriate for the client's teaching.

Choice B reason:

"Take hot showers to help relieve itching" This statement is incorrect. Itching is not mentioned in the vital signs and weight provided. Additionally, taking hot showers might not be relevant to the client's condition or needs. This statement is not appropriate for the client's teaching.

Choice C reason:

"Wear loose-fitting clothing" This is an appropriate statement for the client's teaching. Wearing loose-fitting clothing can provide comfort and allow better circulation, which might be helpful for some clients.

Choice D reason:

"Wear flat or low-heeled shoes" This is an appropriate statement for the client's teaching. Wearing flat or low-heeled shoes can help provide comfort and support, especially if the client has any foot or back issues.

Choice E reason:

"You can douche twice weekly." Douche is not relevant to the vital signs and weight provided, and it is generally not recommended for routine use as it can disrupt the natural balance of vaginal flora. This statement is not appropriate for the client's teaching.

Choice F reason:

"Eat two large meals a day." This statement does not align with a healthy eating pattern, and it might not be appropriate for the client's health needs. The recommendation for a balanced diet usually includes several smaller meals throughout the day. This statement is not appropriate for the client's teaching.

Choice G reason:

"You should avoid fried foods." This is an appropriate statement for the client's teaching. Avoiding fried foods can be beneficial for overall health, especially if the client is trying to manage weight or maintain a balanced diet.

Correct Answer is ["255"]

Explanation

Step 1: Calculate half the total volume. The total volume is 4,080 mL. So, half the total volume is 4,080 mL ÷ 2 = 2,040 mL.

Step 2: Calculate the rate to administer half the total volume in the first 8 hours. So, the rate is 2,040 mL ÷ 8 hr = 255 mL/hr.

Therefore, the nurse should set the IV infusion pump to deliver 255 mL/hr to administer half the total volume in the first 8 hr.
