A client with pernicious anemia takes supplemental folate and self-administers monthly vitamin B12 injections. The client reports feeling increasingly fatigued. Which laboratory value should the nurse review?

Platelet count.

Liver enzymes.

Complete blood count.

Serum electrolytes.

Answer and Explanation

The Correct Answer is C

Choice A reason: Platelet count is important for clotting but does not directly address the cause of fatigue in pernicious anemia.

Choice B reason: Liver enzymes are important for liver function but are not related to pernicious anemia.

Choice C reason:

The correct answer is c) because a complete blood count (CBC) provides information about hemoglobin and hematocrit levels, which are directly impacted by pernicious anemia and can explain the fatigue.

Choice D reason: Serum electrolytes are important but do not directly address the cause of fatigue in pernicious anemia.

A. Bounding pulse, hypertension, and distended neck veins. B. Thready pulse, hypotension, and chest or back pain. C. Urticaria, itching, and wheezing. D. Chills, fever, and tachycardia.

Correct Answer is A

Explanation

Choice A reason:

The correct answer is a) because a bounding pulse, hypertension, and distended neck veins are signs of fluid overload, which can occur during blood transfusions, especially in older adults.

Choice B reason: A thready pulse, hypotension, and chest or back pain are more indicative of shock or severe anemia rather than fluid overload.

Choice C reason: Urticaria, itching, and wheezing suggest an allergic reaction, not fluid overload.

Choice D reason: Chills, fever, and tachycardia can indicate a febrile or transfusion reaction but are not specific to fluid overload.
