Question 1 of 5
What manifestation is not present in dumping syndrome following a gastrectomy?
Correct Answer: D
Rationale: Borborygmi refers to the audible sounds produced by the movement of gas and fluid in the intestines. This can occur in dumping syndrome due to increased intestinal motility and rapid gastric emptying, making this a present manifestation. Nausea and vomiting can occur in dumping syndrome, particularly shortly after eating, due to the rapid movement of food into the small intestine, which can irritate the gut.
Therefore, this is a present manifestation. Dizziness can occur in dumping syndrome, often as a result of rapid shifts in blood volume and blood sugar levels after eating. This symptom can be attributed to the body's response to the sudden influx of food and fluid into the intestines, leading to symptoms like weakness and dizziness. Hence, this is a present manifestation. Hypertension is not typically associated with dumping syndrome. In fact, many individuals may experience hypotension (low blood pressure) due to the rapid shift of fluid to the intestines, which can reduce circulating blood volume.
Question 2 of 5
The nurse is providing teaching to a patient following a gastric bypass. Which statement by the patient indicates an understanding of the need for lifelong monitoring and lifestyle changes?
Correct Answer: C
Rationale: Docusate may not be needed for all patients. Gastric bypass does not eliminate cholesterol risk. Regular electrolyte checks are necessary due to absorption changes. Daily blood sugar monitoring depends on individual risk factors.
Question 3 of 5
A 3-month-old is being treated for gastroesophageal reflux. The health care provider orders 2mg/kg of ranitidine to be administered every 12 hours. The client weighs 10 pounds. The elixir comes in a strength of 15mg/mL. How many mL of ranitidine should the nurse administer to this client per dose?
Correct Answer: 0.6 mL
Rationale: The infant weighs 10 pounds (4.53692 kg). The dose is 2 mg/kg, so 9.07384 mg per dose. The elixir is 15 mg/mL, so 9.07384 mg ÷ 15 mg/mL = 0.60492267 mL, rounded to 0.6 mL.
Question 4 of 5
When scheduling diagnostic tests, which of the following would the nurse schedule last?
Correct Answer: D
Rationale: EGD requires fasting but can be scheduled flexibly. Barium enema requires bowel prep and is done earlier. Ultrasound is non-invasive with minimal prep. CT scans should be last as residual barium from other tests can interfere with imaging.
Question 5 of 5
A 1-month old infant is admitted to the emergency room with severe diarrhea. Which of the following assessments suggests the infant is severely dehydrated?
Correct Answer: C
Rationale: 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. 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. A depressed fontanelle 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. Moist skin and mucous membranes indicate adequate hydration. Flushed skin may occur with certain conditions but does not suggest severe dehydration.
