The nurse is planning care for several patients in the hospital environment. Which is the greatest risk factor for a patient developing Clostridioides difficile?
Recent use of antibiotics
Prolonged rehabilitation unit stay
Current intensive care unit stay
Recent surgical procedure
The Correct Answer is A
A. Recent use of antibiotics is the greatest risk factor for developing C. difficile infection. Antibiotics disrupt the normal gut flora, allowing C. difficile to overgrow and produce toxins that cause severe diarrhea and colitis.
B. Prolonged rehabilitation stays can increase exposure to hospital-acquired infections but are not as strongly associated with C. difficile as antibiotic use.
C. Staying in the ICU can increase the risk for various infections, but it’s the antibiotic use commonly associated with ICU care that elevates C. difficile risk—not the ICU stay itself.
D. Recent surgery may raise infection risk in general, but it is not as specifically linked to C. difficile as antibiotic therapy is.

Correct Answer is D
Explanation
A. Finding comfort in connecting with family is a healthy coping mechanism and a normal part of the grieving process, not an indicator of clinical depression.
B. Loss of appetite can occur with both grief and depression, so it is not specific enough to indicate clinical depression.
C. Intense sadness is a normal reaction to grief, especially shortly after a loss. It is not necessarily pathological.
D. Loss of interest in pleasurable activities (anhedonia) is a hallmark symptom of clinical depression. When sadness persists and interferes with daily functioning and enjoyment of life, it may signal the transition from normal grief to a depressive disorder.
Correct Answer is A
Explanation
A. A hallmark characteristic of bulimia nervosa is binge eating followed by purging (through vomiting, laxative use, etc.) to prevent weight gain. The client’s statement indicates secretive behavior, which is typical for individuals with bulimia nervosa.
B. The statement "I feel a sense of power by restricting my food intake" is more indicative of anorexia nervosa, where the focus is on restricting food to maintain extreme weight loss.
C. Using laxatives only when constipated is not specific to bulimia nervosa, as this disorder often involves excessive purging (including laxative abuse) during binge episodes.
D. The feeling of "emotional high" during binge episodes is more often related to binge eating disorder than bulimia nervosa, which tends to have a focus on shame and guilt after purging.
