A nurse is caring for a client who has been vomiting and has diarrhea. Which of the following findings should the nurse identify as an indication of fluid volume deficit?

The correct answer is choice d. The client’s output was 60 mL for the past 3 hr.

Choice A rationale:

Voiding three times during the night (nocturia) is common in chronic kidney disease (CKD) due to the kidneys’ inability to concentrate urine. While it should be monitored, it is not the most urgent issue.

Choice B rationale:

Burning and discomfort with urination could indicate a urinary tract infection (UTI), which is important to address but not as immediately critical as low urine output.

Choice C rationale:

A WBC count of 11,000/mm² is slightly elevated and could indicate an infection or inflammation, but it is not as urgent as the low urine output.

Choice D rationale:

Low urine output (oliguria) of 60 mL over 3 hours is a critical finding in CKD patients. It indicates potential acute kidney injury or worsening kidney function, which requires immediate attention to prevent further complications.

The correct answer is choice A.

Choice A rationale:

Count the client's radial and apical pulses simultaneously with another nurse. Rationale: In the presence of an irregular heart rate, a pulse deficit might indicate a discrepancy between the peripheral (radial) and central (apical) pulses. Counting the pulses simultaneously with another nurse helps to accurately assess this deficit. By comparing the two pulse rates, the nurse can identify if there is a difference, which might indicate inadequate circulation or irregular heartbeats that aren't effectively transmitting to the peripheral arteries.

Choice B rationale:

Calculate the client's pulse for 30 seconds and multiply by 2. Rationale: While calculating the pulse rate for 30 seconds and then multiplying by 2 is a valid method to determine the heart rate, it doesn't address the specific concern of a pulse deficit. This approach might help in assessing the overall heart rate but doesn't provide information about potential irregularities or discrepancies between peripheral and central pulses.

Choice C rationale:

Assist the client to a side-lying position. Rationale: Assisting the client to a side-lying position doesn't directly relate to the assessment of a pulse deficit. The position of the client wouldn't significantly impact the assessment of irregular heart rates or pulse deficits.

Choice D rationale:

Auscultate the area of the client's chest over the Erb's point. Rationale: Auscultating the area of the client's chest over the Erb's point is a technique used to assess heart sounds, particularly the S2 heart sound. This technique is not relevant to assessing a pulse deficit. It can provide information about heart valve function but doesn't help in evaluating a discrepancy between peripheral and central pulses.
