Correct Answer is B

Explanation

A. Lithotomy position is used for gynecologic, rectal, or urologic exams and would not be comfortable for a client with low back pain.
B. Dorsal recumbent position is correct because it allows the client to lie on their back with knees bent, reducing strain on the lower back while facilitating assessment of the chest, extremities, and peripheral pulses.
C. Sim’s position is used for rectal examinations or enemas and is not ideal for assessing the chest and extremities.
D. Prone position (lying face down) would exacerbate low back pain and make it difficult to examine the chest and extremities.

A. The client's infection is no longer localized and has become systemic. B. The client likely has a cardiac health problem, not a respiratory health problem. C. The client's signs and symptoms are related to hypothermia rather than infection. D. The client's normothermic temperature does not rule out the presence of an infection.

Correct Answer is D

Explanation

A. Systemic infection can cause fever, but older adults often present with atypical signs, including a lack of fever, rather than the classic response.
B. The presence of a productive cough, abnormal breath sounds, and shortness of breath suggests a respiratory infection rather than a cardiac issue.
C. While older adults may be more susceptible to hypothermia, the client’s symptoms align with infection rather than hypothermia.
D. "The client's normothermic temperature does not rule out the presence of an infection" is correct because older adults may have a blunted febrile response to infection due to age-related changes in thermoregulation. An absence of fever does not exclude infection in elderly patients.
