A patient has a PRN prescription for ondansetron. For which condition would the nurse administer this medication?
GERD
Paralytic ileus
Diarrhea
Nausea and vomiting
The Correct Answer is D
A. Gastroesophageal reflux disease (GERD) is primarily treated with acid-reducing medications (like proton pump inhibitors) and lifestyle changes. Ondansetron is not indicated for GERD as it does not address the underlying acid reflux issues or symptoms related to that condition.
B. Paralytic ileus is a condition where there is a temporary cessation of bowel activity. While nausea and vomiting may occur as a symptom, ondansetron does not address the cause of ileus and may not be appropriate as a treatment option. Treatment typically focuses on resolving the underlying cause and may include bowel rest and monitoring.
C. Ondansetron is not typically used for diarrhea. Diarrhea management usually involves hydration and possibly medications like loperamide, depending on the cause. Ondansetron is not indicated for treating diarrhea as it primarily targets nausea and vomiting.
D. Ondansetron is specifically indicated for the prevention and treatment of nausea and vomiting, particularly those associated with chemotherapy, radiation therapy, or postoperative states. It works by blocking serotonin receptors in the brain that trigger the vomiting reflex.

Correct Answer is C
Explanation
A. Sucralfate works by forming a protective barrier over the ulcer and is best taken on an empty stomach. Antacids can interfere with the effectiveness of sucralfate if taken simultaneously. It’s usually recommended to wait at least 30 minutes to 1 hour after taking sucralfate before taking an antacid.
B. Sucralfate should be stored at room temperature, away from moisture and heat, but it does not need to be refrigerated. This guidance is essential to ensure that the medication maintains its effectiveness.
C. Sucralfate is typically taken 1 hour before meals and at bedtime to optimize its protective effect on the stomach lining and ulcers. This timing allows it to coat the ulcer effectively before food intake.
D. Sucralfate tablets should be swallowed whole and not crushed or chewed, as doing so may affect how the medication works. This instruction helps ensure that the sucralfate can properly adhere to the ulcer surface.
Correct Answer is ["B","C"]
Explanation
A. Living independently does not inherently increase the risk for C. difficile. Risk factors are more related to antibiotic use, exposure in healthcare settings, and individual health conditions rather than the living situation itself.
B. A weakened immune system (due to conditions like HIV/AIDS, cancer, or immunosuppressive therapy) can increase susceptibility to infections, including C. difficile. Individuals with compromised immunity are less able to fight off infections.
C. The use of antibiotics is a significant risk factor for C. difficile infection. Antibiotics can disrupt the normal gut flora, leading to overgrowth of C. difficile and subsequent infection.
D. While watery diarrhea is a common symptom of C. difficile infection, it is not a risk factor for developing the infection itself. Instead, it indicates that the infection is already present. Thus, this option does not contribute to the risk of developing C. difficile.
E. Fever is often a symptom of an underlying infection but is not a direct risk factor for developing C. difficile. It can occur with C. difficile infection but does not increase the likelihood of becoming infected.
