The nurse observes that a client is experiencing melena.Which serum laboratory test should the nurse monitor in response to this finding?

White blood cell count (WBC).

Blood urea nitrogen (BUN).

Hematocrit.

Glucose.

Answer and Explanation

The Correct Answer is C

Choice A rationale
White blood cell count (WBC) is typically monitored to assess for signs of infection or inflammation. While it’s important to monitor WBC count in certain situations, such as suspected infection, melena itself is not directly indicative of an increased risk of infection.
Choice B rationale
Blood urea nitrogen (BUN) levels can be elevated in cases of gastrointestinal bleeding due to the breakdown of blood proteins in the gut. However, BUN is not the primary test to monitor in response to melena.
Choice C rationale
Hematocrit is the correct answer. Hematocrit levels are crucial to monitor in cases of melena because they provide information about the client’s red blood cell volume and can indicate the extent of blood loss.
Choice D rationale
Glucose levels are not directly related to melena. Monitoring glucose levels is essential for managing diabetes and other metabolic conditions but is not relevant to assessing the impact of gastrointestinal bleeding.

Correct Answer is ["B","C","E"]

Explanation

Choice A rationale
Measuring skin elasticity around the ankles is not directly related to assessing the cause of cold feet. It is more relevant for assessing hydration status and skin turgor.
Choice B rationale
Assessing the volume of the pedal pulses is crucial to determine if there is adequate blood flow to the feet.
Choice C rationale
Palpating the dorsal surface of the feet for warmth helps assess the temperature and circulation to the feet.
Choice D rationale
Testing for a positive Babinski reflex is not relevant to assessing cold feet. It is used to assess neurological function.
Choice E rationale
Observing the color of the feet and toes helps assess circulation and potential issues such as cyanosis or pallor.

A. Place a mark where DP pulse is auscultated. B. Use a doppler to assess an audible DP pulse. C. Assess capillary refill distal to the DP pulse. D. Review client’s history for vascular disease.

Correct Answer is B

Explanation

Choice A rationale
Placing a mark where the DP pulse is auscultated can help in future assessments but does not address the immediate need to locate the pulse.
Choice B rationale
Using a Doppler to assess an audible DP pulse is the correct answer. A Doppler ultrasound device is helpful when it is impossible or difficult to assess a pulse or when pulses are not palpable.
Choice C rationale
Assessing capillary refill distal to the DP pulse is important but should be done after attempting to locate the pulse with a Doppler.
Choice D rationale
Reviewing the client’s history for vascular disease is essential for understanding the underlying cause but does not address the immediate need to locate the pulse.
