The nurse is evaluating the outcome of the treatment goals for a client with heart failure.
Which of the following would be the best query for the nurse to ask?
How has your energy level been?
How many pillows are you using to sleep?
Have you been exercising regularly?
Have you had any chest pain?.
The Correct Answer is B
Choice A rationale
Assessing energy levels provides indirect information about cardiac output but lacks specificity regarding fluid overload or pulmonary congestion, which are key indicators of heart failure exacerbation. It is a relevant question but not the best for evaluating treatment outcomes.
Choice B rationale
Asking about pillow use evaluates orthopnea, a common symptom of heart failure due to fluid buildup in the lungs when lying flat. It provides a direct assessment of fluid status and the effectiveness of heart failure management, making it the best question.
Choice C rationale
Exercising regularly is an important lifestyle aspect for heart failure patients but does not directly assess the status of symptoms such as fluid overload or cardiac function. Thus, it is not the most critical outcome measure.
Choice D rationale
Chest pain can indicate ischemia or worsening cardiac function but is not specific to fluid status or pulmonary congestion in heart failure. Therefore, it is a relevant but less optimal question for evaluating treatment goals.

Correct Answer is C
Explanation
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 ["12"]
Explanation
Step 1 is to convert 176 pounds to kilograms. (176 ÷ 2.2) = 80 kg.
Step 2 is to calculate the drug dose. (10 mcg × 80 kg) ÷ 1000 = 0.8 mg/minute.
Step 3 is to find the hourly dose. (0.8 mg × 60 minutes) = 48 mg/hour.
Step 4 is to calculate mL/hour. (48 mg ÷ (1000 mg ÷ 250 mL)) = 12 mL/hour. The final calculated answer is 12 mL/hour.
