A nurse on the oncology unit is evaluating a client's response after receiving a dose of aprepitant. Which of the following therapeutic effects should the nurse expect?

Occupational therapist. Disuse syndrome is a condition that occurs when a person experiences a reduction in physical activity, resulting in a decline in physical function. An occupational therapist can help the client improve their ability to perform daily activities and improve their overall functioning. A social worker can help the client and their family with emotional and social issues related to the condition. An herbalist is not necessary for the management of disuse syndrome. A dietitian can help the client with their nutritional needs but may not address their physical functioning.

Palpable area of induration, greater than 10 mm (0.4 in) in diameter. This indicates a positive tuberculin skin test (TST) reaction for a person with no known risk factors for TB infection. A positive TST reaction means that the person has been infected with Mycobacterium tuberculosis, the bacterium that causes TB disease, and needs further testing to confirm the diagnosis and rule out active TB disease.

The other choices are not correct because:

- Choice A. Nonpalpable area of redness, less than 5 mm (0.2 in) in diameter. This indicates a negative TST reaction for any person, regardless of their risk factors for TB infection. A negative TST reaction means that the person has not been infected with Mycobacterium tuberculosis or has a very low level of immune response to the bacterium.

- Choice B. Area of ecchymosis, greater than 12 mm (0.5 in) in diameter. This indicates a bruise or bleeding under the skin, not a TST reaction. Ecchymosis is not caused by the injection of tuberculin purified protein derivative (PPD) into the skin, but by trauma or injury to the blood vessels.

- Choice C. Tenderness at the injection site. This indicates a mild local reaction to the injection of tuberculin PPD into the skin, not a TST reaction. Tenderness is not measured in millimeters of induration (firm swelling), which is the standard way of reading TST results.
