A nurse is teaching a client who was diagnosed with prolonged grief disorder about the importance of cognitive behavioral therapy (CBT), which of the following client statements indicates an understanding of the teaching?

Rationale:

A. Placing a client with active tuberculosis in a room with another client increases the risk of airborne transmission of the infection, which is inappropriate for infection control.

B. A room with air exhaust directly to the outdoor environment is ideal for a client with active tuberculosis because it provides negative pressure, helping to contain and prevent the spread of the infectious airborne particles.

C. The ICU is typically reserved for critically ill patients requiring intensive monitoring and care, and it may not provide the necessary infection control measures for TB.

D. A room near the nurses' station would not ensure the negative pressure ventilation needed to prevent airborne transmission of tuberculosis.

Rationale:

A. An inverted P wave is not specifically associated with hypokalemia; it can be seen in various other conditions.

B. An elevated ST segment is not characteristic of hypokalemia; it is more associated with other conditions such as myocardial ischemia.

C. A wide QRS complex can occur with hypokalemia but is also seen in other conditions.

D. An abnormally prominent U wave is a classic sign of hypokalemia and can be seen in EKG changes associated with low potassium levels.
