Correct Answer: B

Rationale: The correct answer is B: Bradycardia. Bradycardia, or a slow heart rate, is a common finding in clients with hypothyroidism because of the decreased metabolic rate associated with this condition. Weight gain is also a common symptom of hypothyroidism due to the metabolic changes, making choice A incorrect. Tachycardia, or a rapid heart rate, is typically seen in hyperthyroidism, not hypothyroidism, so choice C is incorrect. Heat intolerance is more commonly associated with hyperthyroidism rather than hypothyroidism, making choice D incorrect.

Correct Answer: A

Rationale: The correct answer is to place the client in a private room with negative airflow. This is crucial for preventing the spread of tuberculosis (TB) infection. Option B, wearing an N95 respirator when caring for the client, is important for staff protection but does not address the need for isolation precautions. Option C, placing the client in a positive pressure room, is incorrect as TB clients should be in negative pressure rooms to prevent the spread of airborne pathogens. Option D, maintaining the client on droplet precautions, is not sufficient for TB, which requires airborne precautions.

Correct Answer: C

Rationale: In Cushing's disease, there is increased cortisol production, which can lead to various metabolic disturbances. One of the common findings is an increased serum potassium level. The other options are incorrect because Cushing's disease typically causes hyperglycemia, not decreased serum glucose levels (A), lymphocytopenia, not increased lymphocyte count (B), and hyponatremia, not decreased serum sodium level (D).

Correct Answer: C

Rationale: Using an abduction pillow between the client's legs is essential in maintaining proper alignment and preventing dislocation of the hip joint following a hip arthroplasty. Encouraging the client to lie flat in bed (Choice A) is not recommended as early mobilization is crucial for preventing complications. Applying heat to the incision site (Choice B) is not typically done immediately postoperatively. Placing a trochanter roll under the client's knees (Choice D) is not as beneficial as using an abduction pillow to maintain proper positioning.

Correct Answer: C

Rationale: The correct answer is lean beef because it is a good source of protein and essential nutrients. When providing dietary recommendations to clients with hypertension, it is important to focus on lean protein sources to promote a balanced diet. Bananas, although a healthy fruit, may not be the best choice due to their high potassium content, which can sometimes be a concern for individuals with hypertension. Whole grains are generally a good choice, but lean protein like beef is more suitable in this scenario. Canned soup often contains high levels of sodium, which is not recommended for individuals with hypertension.
