A client has a history of gastric bypass surgery within the past year. She presents to her primary care office for a check-up and states she has been troubled by several seemingly unrelated ailments: a sore tongue, tingling in her fingers, and “almost” falling several times due to lack of balance. The nurse notes that she is pale and slightly tachycardic.
Which type of anemia does the nurse suspect?
Folic acid deficiency anemia.
Aplastic anemia.
Vitamin B12 deficiency anemia.
Acquired anemia.
The Correct Answer is C
This type of anemia is caused by the reduced absorption of vitamin B12 in the small intestine after gastric bypass surgery. Vitamin B12 is needed for the production of healthy red blood cells and nerve function. The symptoms of vitamin B12 deficiency anemia include sore tongue, tingling in the fingers, and balance problems.
Choice A is wrong because folic acid deficiency anemia is caused by the lack of folic acid in the diet or increased demand for folic acid, such as during pregnancy.
Folic acid is also needed for red blood cell production, but it does not cause nerve symptoms.
Choice B is wrong because aplastic anemia is caused by the failure of the bone marrow to produce enough blood cells.
It is not related to gastric bypass surgery or nutrient deficiency. It can be caused by infections, drugs, radiation, or autoimmune diseases.
Choice D is wrong because acquired anemia is a general term for any type of anemia that is not inherited or present at birth.
It can have many causes, such as blood loss, infection, inflammation, or chronic disease.
It does not specify the type of anemia or the underlying mechanism. Normal ranges for hemoglobin are 13.5 to 17.5 g/dL for men and 12 to 15.5 g/dL for women. Normal ranges for vitamin B12 are 200 to 900 pg/mL.

Correct Answer is D
Explanation
Replacing wet clothing with dry clothing is an independent nursing intervention that can help prevent further heat loss and gradually warm the patient. Soaking extremities in hot water (choice A) is not recommended because it can cause vasodilation and hypotension. Administering warmed intravenous fluids (choice B) and administering hot whirlpool therapy (choice C) are not independent nursing interventions because they require a physician’s order. They are also not appropriate for mild to moderate hypothermia because they can cause rapid rewarming and cardiac dysrhythmias.
Correct Answer is A
Explanation
This means that the blood flow to the affected area is reduced due to narrowed or blocked arteries. This can cause tissue death or gangrene. Diabetes can
damage the blood vessels and affect blood flow, increasing the risk of gangrene. Choice B. Stasis is wrong because it refers to a condition where blood pools in the veins of the legs, causing swelling and skin changes. It does not cause gangrene by itself.
Choice C. Venous insufficiency is wrong because it refers to a condition where the veins in the legs have problems sending blood back to the heart, causing swelling and skin ulcers. It does not cause gangrene by itself.
Choice D. Varicose veins are wrong because they are enlarged veins that may cause pain or discomfort, but do not cause gangrene by themselves.
