An older adult male arrives at the healthcare center with lower abdominal discomfort and frequent urination. The nurse asks the client to provide a urine sample. After an extended period of time, the client returns with only a few drops of urine. Which action should the nurse implement?

Answer: B. Cardiac enlargement.

Rationale:

A) Cardiac atrophy:
Cardiac atrophy refers to the reduction in the size of the heart muscles and is not typically detected through percussion. It would present differently, likely through imaging or echocardiography, rather than an increase in the area of dullness during percussion.

B) Cardiac enlargement:
Percussion revealing dullness extending from the 5th left intercostal space upward to the 2nd left intercostal space suggests an increase in the size of the heart. This pattern indicates cardiac enlargement, as the heart’s borders have extended beyond their typical boundaries, which are usually confined to the 5th left intercostal space along the midclavicular line.

C) Benign variation:
A benign variation would not typically cause such a significant change in the area of cardiac dullness. This finding is more concerning for pathology, such as cardiomegaly, than a harmless variation.

D) Expected finding:
The normal borders of the heart should not extend upward to the 2nd left intercostal space during percussion. This finding is not within normal limits and suggests an abnormal enlargement of the heart, rather than an expected physiological outcome.

A. Give the client 8 ounces (236.5 mL) of water to drink:
While encouraging hydration is important for overall urinary function, providing water to drink may not immediately address the client's current situation of difficulty providing a urine sample. It's essential to first determine if bladder distention is contributing to the client's symptoms.

B. Evaluate the client for bladder distention:
Given the client's symptoms of lower abdominal discomfort and difficulty providing a urine sample despite feeling the urge to urinate, bladder distention should be assessed. Bladder distention could indicate urinary retention, which may require intervention to relieve the discomfort and prevent complications such as urinary tract infection or bladder rupture.

C. Instruct the client to attempt to urinate again:
While encouraging the client to attempt to urinate again may be appropriate, it's essential to first assess for bladder distention to determine if there is an underlying issue contributing to the client's difficulty in providing a urine sample.

D. Send the sample for laboratory evaluation:
Sending the urine sample for laboratory evaluation is important for diagnostic purposes, but in this case, it's more important to address the immediate concern of the client's difficulty in providing an adequate sample. Evaluating for bladder distention would help guide further assessment and management.
