Correct Answer: D

Rationale: All of the factors listed (age, nutritional status, close proximity to other patients, and inadequate stress management) can increase a patient's potential for acquiring a nosocomial infection. Age can weaken the immune system, making individuals more susceptible to infections. Poor nutritional status can impair immune function, making it harder for the body to fight off infections. Close proximity to other patients increases exposure to pathogens, and inadequate stress management can further weaken the immune system, increasing the risk of acquiring infections. Therefore, all these factors can contribute to a patient's potential for acquiring a nosocomial infection.

Correct Answer: C
