The nurse is caring for a 32-year old client admitted with pernicious anemia. Which set of findings should the nurse expect when assessing the client?

Correct Answer: D

Rationale: The correct answer is D: Pallor, tachycardia, and a sore tongue. Pernicious anemia is caused by a deficiency in vitamin B12, leading to symptoms such as pallor (due to decreased red blood cells), tachycardia (as the heart works harder to compensate for decreased oxygen-carrying capacity of the blood), and a sore tongue (due to inflammation of the tongue). Choice A is incorrect because bradycardia would not be expected in pernicious anemia, and reduced pulse is not a typical finding. Choice B is incorrect because weight gain is not a common symptom of pernicious anemia. Choice C is incorrect because angina and double vision are not typical findings of pernicious anemia, and anorexia is more likely due to other causes.

Correct Answer: A

Rationale: The correct answer is A because a positive diagnosis for HIV infection is confirmed through laboratory testing, specifically the ELISA and Western blot tests. These tests detect the presence of HIV antibodies in the blood, providing definitive evidence of the infection. Choice B is incorrect as weight loss and fever are symptoms but not diagnostic criteria. Choice C is incorrect as opportunistic infections are a consequence of HIV, not the diagnostic criteria. Choice D is incomplete and irrelevant. In summary, the key to diagnosing HIV is through positive laboratory tests, not just based on symptoms or associated infections.

Correct Answer: C

Rationale: The correct answer is C: Lean red meats. Lean red meats are a rich source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Heme iron helps improve iron levels more effectively in individuals with iron deficiency anemia. Fresh fruits (A) and dairy products (B) contain minimal iron, while breads and cereals (D) provide non-heme iron which is not as readily absorbed.

Correct Answer: B

Rationale: Severe and extensive hemolysis leads to the release of large amounts of hemoglobin into the bloodstream, causing hemoglobinemia. This can result in hemoglobinuria, leading to acute renal failure and ultimately shock. Shock is the correct answer as it is a severe consequence of extensive hemolysis. Leg ulcers (A) may occur in conditions like peripheral arterial disease. Priapism (C) is unrelated to hemolysis. Compromised growth (D) is not a common consequence of hemolysis.

Correct Answer: A

Rationale: The correct answer is A: Infection. After a splenectomy, the client is at risk for infection due to the spleen's role in the immune system. Without the spleen, the body's ability to fight infections is reduced. Infections can be serious and life-threatening. B: Urinary retention is not a typical complication of a splenectomy. C: Congestive heart failure is not directly related to a splenectomy. D: Viral hepatitis is not a common complication of a splenectomy.
