A nurse is performing the initial history and physical examination of a patient diagnosed with a duodenal ulcer. Which type of pain does the nurse expect the patient to describe?

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.

A. A high specific gravity of urine typically indicates concentrated urine, which can occur in dehydration; however, moist mucous membranes suggest adequate hydration. This combination does not indicate severe dehydration.
B. A low specific gravity of urine usually indicates dilute urine, which is not typical in dehydration; it suggests the kidneys are not concentrating urine due to good fluid intake or other factors. While pale skin can indicate poor perfusion, this option does not specifically indicate severe dehydration.
C. A depressed fontanelle (soft spot on the head) and a capillary refill time greater than 4 seconds are significant indicators of severe dehydration in infants. Depressed fontanelles suggest that the infant is not receiving enough fluids, and prolonged capillary refill time indicates poor perfusion and dehydration.
D. Moist skin and mucous membranes indicate adequate hydration. Flushed skin may occur with certain conditions but does not suggest severe dehydration. This option reflects a well-hydrated status rather than dehydration.
