Correct Answer: A

Rationale: The correct answer is A: Avoid alcohol and caffeine. Alcohol and caffeine are diuretics that can increase urine output, leading to fluid loss and potential hypovolemia. This step is crucial in preventing further dehydration. Summary of incorrect choices: B: Increasing milk and dairy products can contribute to fluid intake but does not address the prevention of hypovolemia. C: While dried peas and beans can provide nutrients, they do not specifically address fluid intake or prevention of hypovolemia. D: Avoiding table salt or sodium-containing foods may help in reducing fluid retention but does not directly address fluid intake to prevent hypovolemia.

Correct Answer: C

Rationale: The correct answer is C: Surgical removal. Surgical removal of the cancerous tumor is the best treatment before metastasis because it physically removes the cancer cells. Chemotherapy and radiation are used to treat cancer after it has spread, not as the primary treatment. Choice D is incorrect because not all types of cancer can be effectively treated with all three options.

Correct Answer: B

Rationale: The correct answer is B because it directly reflects the client's progress in physical activity, a key indicator of recovery post-myocardial infarction. Walking 500 meters without chest pain shows improved cardiovascular function and exercise tolerance. Vital signs and lab results from admission (A) are important for initial assessment but not for ongoing evaluation. Physician notes (C) may provide insights but do not directly measure the client's progress. Medications prescribed (D) are important but do not reflect the client's specific improvement in physical activity.

Correct Answer: D

Rationale: The correct answer is D because a regular diet with extra fruits and green vegetables can provide essential nutrients for overall health, potassium-sparing diuretics can help manage potassium levels in the body, and discontinuing oral magnesium salts can prevent further complications in the patient. Option A focuses on promoting a healthy diet, B addresses specific medication for potassium management, and C avoids potential interactions with magnesium salts. Therefore, all of the measures (A, B, and C) are necessary for comprehensive management of the patient's condition.

Correct Answer: B

Rationale: The correct answer is B: Volume overload with hemodilution. In deep partial-thickness burns, there can be fluid shifts leading to volume overload. This excess fluid in the intravascular space can dilute the blood, resulting in a decreased hematocrit (Hct). Reduced Hct indicates lower concentration of red blood cells in the blood. Other choices are incorrect because hypoalbuminemia would lead to hemoconcentration, metabolic acidosis would not directly cause a reduced Hct, and lack of erythropoietin factor would primarily affect erythropoiesis but not directly lead to decreased Hct.
