Correct Answer: D

Rationale: The correct answer is D. Swelling in the feet can indicate worsening heart failure due to fluid retention, and clients should report this to their healthcare provider immediately. Choices A, B, and C are incorrect because weighing once a week may not provide timely information on fluid retention, timing of diuretic medication is usually advised in the morning to prevent nocturia, and limiting fluid intake to 3 liters per day may not be appropriate for all clients with heart failure.

Correct Answer: A

Rationale: Measuring the client's abdominal girth daily is the most effective way to monitor the reduction of ascites and fluid retention in clients with liver cirrhosis. This measurement helps assess the effectiveness of treatment in managing ascites by monitoring changes in abdominal size. Monitoring the client's hemoglobin level (Choice B) is not directly related to assessing the effectiveness of ascites treatment. Administering lactulose as prescribed (Choice C) is important in managing hepatic encephalopathy, not ascites. Weighing the client weekly (Choice D) may not provide real-time feedback on the reduction of ascites compared to daily abdominal girth measurements.

Correct Answer: A

Rationale: The correct answer is A: 'If I eat 500 fewer calories per day, I should lose 1 pound per week.' This statement is accurate because a reduction of 500 calories per day typically results in a weight loss of 1 pound per week. This is based on the principle that a calorie deficit of 3,500 calories equals about 1 pound of body fat. Choices B, C, and D are incorrect because they do not align with the established relationship between calorie reduction and weight loss. Eating 450 fewer calories per day would not lead to a weight loss of 2 pounds per week; similarly, reducing calories by 250 or 300 per day would not result in losing 2 pounds or 1 pound per week, respectively.

Correct Answer: B

Rationale: In chronic kidney disease, the kidneys have impaired ability to activate vitamin D, leading to decreased production of calcitriol. Calcitriol is essential for calcium absorption in the intestines. Therefore, hypocalcemia is a common finding in chronic kidney disease. Hypernatremia (increased sodium levels) is not typically associated with chronic kidney disease. Low potassium and low magnesium are possible electrolyte imbalances in chronic kidney disease, but they are not as directly related to the impaired activation of vitamin D as hypocalcemia.

Correct Answer: C

Rationale: The correct action the nurse should take is to wrap monitoring cords with stockinette. This measure ensures that the latex in the cords does not come into contact with the client's skin, reducing the risk of an allergic reaction. Applying tape to the client's skin before surgery (Choice A) may expose the client to latex if the tape contains latex. Ensuring the surgical suite is well-ventilated (Choice B) is important for overall safety but does not specifically address the client's latex allergy. Scheduling the surgery at the end of the day (Choice D) is not directly related to preventing latex exposure and allergic reactions.
