The nurse has taught nutrition management for a client diagnosed with oxalate kidney stones.
Which of the following food choices by the client would indicate that the client requires more teaching?
Venison stew and ice cream.
Poached salmon and green beans.
Spinach salad and rhubarb pie.
Sautéed mushrooms and fried rice.
The Correct Answer is C
Choice A rationale
Venison stew and ice cream are low in oxalate content. Oxalate kidney stones are formed due to high urinary oxalate levels, often from consuming oxalate-rich foods. Venison provides protein but does not contribute significantly to oxalate levels, while dairy products like ice cream have calcium which binds oxalate, reducing absorption in the gut.
Choice B rationale
Poached salmon and green beans are suitable choices as they have low oxalate content. Salmon provides omega-3 fatty acids, which can reduce kidney stone risk, and green beans are a low-oxalate vegetable, making this meal appropriate for oxalate management.
Choice C rationale
Spinach and rhubarb are high in oxalates. Spinach contains around 750 mg oxalates per 100 grams, and rhubarb contains 860 mg per 100 grams. Consuming these increases urinary oxalate excretion, elevating the risk of stone formation, indicating a need for further dietary education.
Choice D rationale
Sautéed mushrooms and fried rice are acceptable as both are low in oxalates. Mushrooms provide nutrients like selenium and vitamin D, while rice is a carbohydrate source free from oxalate, making this option suitable for oxalate kidney stone prevention.

Correct Answer is C
Explanation
Choice A rationale
Trouble breathing is a hallmark symptom of left-sided heart failure. Suggesting that it should not occur would be inaccurate. The failure of the left ventricle leads to blood accumulation in the pulmonary vessels, creating pulmonary congestion and shortness of breath. Prompt provider notification may be necessary but does not address the underlying pathophysiology. Pulmonary symptoms are expected in this type of heart failure.
Choice B rationale
While left-sided heart failure can eventually lead to right-sided heart failure, the initial problem is with left ventricular dysfunction. This causes reduced forward blood flow and pulmonary congestion due to backflow of blood into the lungs. Right-sided heart failure is not the primary event leading to pulmonary symptoms in left-sided heart failure.
Choice C rationale
The left ventricle's inability to pump effectively results in blood backing up into the pulmonary circulation, causing pulmonary congestion and symptoms like shortness of breath. This is consistent with the hemodynamics of left-sided heart failure. Pulmonary capillary pressure increases, leading to fluid leakage and impaired gas exchange, explaining the client's breathing difficulty.
Choice D rationale
Although difficulty breathing with exertion (dyspnea on exertion) is common, resting symptoms, including orthopnea and paroxysmal nocturnal dyspnea, can also occur in left-sided heart failure due to fluid redistribution. Limiting symptoms to exertion inaccurately portrays the clinical presentation and disregards other significant pulmonary signs.
Correct Answer is A
Explanation
Choice A rationale
Corticosteroids are used in thrombocytopenia because they suppress the immune response, particularly in immune thrombocytopenic purpura (ITP). They reduce platelet destruction by inhibiting autoantibody formation and increasing platelet lifespan. Normal platelet count ranges from 150,000 to 400,000/µL. Thrombocytopenia occurs when platelets drop below 150,000/µL, increasing bleeding risk. Corticosteroids can also decrease capillary permeability, minimizing petechiae and ecchymoses.
Choice B rationale
Diphenhydramine, an antihistamine, is used for allergic reactions but has no role in treating thrombocytopenia. It does not address the underlying immune or hematologic causes of low platelet counts. Its primary actions include H1 receptor antagonism, reducing histamine-mediated symptoms like itching and swelling. However, it lacks immunosuppressive or hematologic-stimulating effects essential for managing thrombocytopenia.
Choice C rationale
Desmopressin (DDAVP) is a synthetic antidiuretic hormone analog used for certain bleeding disorders like von Willebrand disease or mild hemophilia A. It increases factor VIII and von Willebrand factor levels, improving clotting. However, it is not indicated for thrombocytopenia as it does not address platelet count deficiencies or immune-mediated platelet destruction.
Choice D rationale
Hydrochlorothiazide (HCTZ) is a thiazide diuretic used for hypertension and edema. Its mechanism of action involves inhibiting sodium reabsorption in the distal tubule, promoting diuresis. HCTZ has no effect on platelet counts or immune mechanisms and is not used in thrombocytopenia. Its side effects, like electrolyte imbalances, may complicate patient management.
