A nurse is collecting data from a client who is 8 hr postoperative following abdominal surgery. The client's blood pressure is 94/56 mm Hg. Which of the following actions should the nurse take first?

A. Temperature: The temperature remains stable and within normal limits. A postoperative temperature range of 36.3° C (97.3° F) to 36.4° C (97.5° F) is not indicative of infection or other complications at this time.

B. Heart rate: The heart rate has increased from 84/min to 104/min, indicating sinus tachycardia. This could be a compensatory response to decreased blood volume or another underlying issue, necessitating further assessment.

C. Skin findings: The skin findings are described as warm and dry, which is normal. No abnormalities are noted, so this does not require follow-up.

D. Respiratory rate: The respiratory rate has increased slightly to 24/min but is not significantly abnormal. This may not be a priority for follow-up unless other symptoms are present.

E. Oxygen saturation: The oxygen saturation is within normal limits (96% on room air), suggesting adequate oxygenation. No immediate concerns are evident based on this measurement.

F. Blood pressure: The blood pressure has dropped from 106/74 mm Hg to 88/54 mm Hg, indicating possible hypotension. This drop could signal hypovolemia or bleeding, requiring prompt follow-up to investigate the cause.

G. Urinary output: The urinary output of 110 mL over 6 hours is low, which might indicate dehydration or renal issues. Monitoring and addressing this finding are important to ensure adequate fluid balance and kidney function.

A. Clean the client's finger with hexachlorophene: Hexachlorophene is not recommended for cleaning the skin before blood glucose testing; a mild soap and water or an alcohol swab is typically used.
B. Apply the first drop of blood to the test strip: The first drop of blood is often not used due to potential contamination; the nurse should usually wipe away the first drop and use the second one.
C. Hold the client's finger in a dependent position: This is correct as holding the finger downward can help increase blood flow to the fingertip, facilitating easier blood collection.
D. Prick the central tip of the client's finger: Pricking the central tip can be painful; the sides of the fingertip are preferred for less discomfort and to avoid nerve endings.
