Correct Answer: B

Rationale: The correct answer is to place the client in a private room. Clostridium difficile (C. diff) infection requires contact precautions, which include isolating the client in a private room to prevent the spread of infection to others. Wearing a face shield may be necessary in certain situations for protection but is not the primary measure for C. diff. Placing the client in a negative pressure room is not specifically indicated for C. diff unless the client has additional respiratory issues. Using alcohol-based hand rub following client care is not sufficient for C. diff control; thorough handwashing with soap and water is recommended due to the spore-forming nature of C. diff.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor for diaphoresis.' Diaphoresis, which refers to excessive sweating, is a common symptom of hypoglycemia. It indicates a low blood sugar level and should prompt immediate treatment. Polyuria (excessive urination), abdominal pain, and thirst are not typically associated with hypoglycemia. Polyuria is more commonly linked to hyperglycemia, while abdominal pain and thirst are not specific symptoms of hypoglycemia.

Correct Answer: B

Rationale: Diminished deep tendon reflexes are a sign of magnesium toxicity. Magnesium sulfate can depress the central nervous system, leading to decreased reflexes. Respiratory rate of 12/min, urine output 40 mL/hr, and systolic blood pressure of 140 mm Hg are not specific findings of magnesium toxicity. Respiratory depression, oliguria, and hypotension are more concerning signs that require immediate attention.

Correct Answer: B

Rationale: Fullness in the throat after a thyroidectomy could indicate bleeding or a hematoma, which can compress the airway, so hemorrhage is the priority concern. Hypocalcemia typically presents with symptoms like tingling around the mouth or in the extremities, muscle cramps, or seizures, not fullness in the throat. Hypoxia would manifest with symptoms like shortness of breath, confusion, or cyanosis, rather than a feeling of fullness in the throat. Hypothyroidism symptoms include fatigue, weight gain, and cold intolerance, but it does not typically cause acute fullness in the throat postoperatively.

Correct Answer: C

Rationale: The correct answer is to instruct the client to restrict protein intake. In chronic renal failure, the kidneys are unable to effectively filter waste products, so limiting protein helps reduce the buildup of waste in the body. Increasing calcium intake (Choice A) is not typically necessary unless there is a specific deficiency. Providing a diet high in potassium (Choice B) is contraindicated as potassium levels need to be monitored and controlled in renal failure. Increasing fluid intake (Choice D) may be necessary depending on the individual's condition, but restricting protein intake is a more critical dietary instruction for clients with chronic renal failure.
