A charge nurse is planning a room assignment for a client who has a productive cough, a questionable chest x-ray, and a positive Mantoux test. Room 208 is a private, negative-pressure airflow room; room 212 is a semi-private, positive-pressure airflow room; 214 is a negative-pressure, semi-private room; and room 216 is a private, positive-pressure airflow room. To which of the following rooms should the nurse assign the client?

A. Bone density: Passive range of motion exercises do not significantly impact bone density. Weight-bearing exercises are more effective for increasing bone density.
B. Joint flexibility: Passive range of motion exercises help maintain or improve joint flexibility by moving the joints through their full range of motion.
C. Muscle mass: Passive range of motion does not increase muscle mass. It is used to maintain flexibility and prevent contractures rather than to build muscle.
D. Muscle strength: Passive range of motion exercises do not increase muscle strength. Active range of motion or resistance exercises are required to improve muscle strength.

A. Orthostatic hypotension increases a client's risk of a fall: Correct. Orthostatic hypotension can lead to dizziness or lightheadedness when standing, increasing the risk of falls.
B. Orthostatic hypotension is indicated by a decrease in systolic blood pressure of 10 mm Hg: This is not specific enough. Orthostatic hypotension is typically defined by a decrease in systolic blood pressure of 20 mm Hg or more when standing.
C. Orthostatic hypotension increases a client's risk of a pulmonary emboli: This is not directly related. Orthostatic hypotension mainly affects balance and fall risk, not the risk of pulmonary emboli.
D. Orthostatic hypotension is indicated by a decrease in diastolic blood pressure of 5 mm Hg: This is incorrect. Orthostatic hypotension is more commonly assessed by a significant drop in systolic blood pressure rather than diastolic pressure.
