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? (round to the nearest tenth)

Answer and Explanation

The Correct Answer is ["0.6"]

The infant weighs 10 pounds, which is equivalent to about 4.53692 kilograms (10 x 0.453592). The prescribed dose is 2 mg/kg, so the total dose per administration is 9.07384 mg (2 mg/kg x 4.53692 kg).

Since the elixir's strength is 15 mg/mL, we divide the total dose by the strength of the elixir to find out how many mL to administer: 9.07384 mg ÷ 15 mg/mL = 0.60492267 mL. Rounding to the nearest tenth, the nurse should administer 0.6 mL of ranitidine per dose to the infant.

Correct Answer is C

Explanation

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.

A. Epigastric pain B. Murphy's Sign C. Green colored stool D. Nausea and vomiting

Correct Answer is C

Explanation

A. Epigastric pain is a common symptom of cholecystitis. Patients often experience pain in the upper abdomen, which can radiate to the right shoulder or back. This symptom is typical in cases of gallbladder inflammation.
B. Murphy's sign is a physical examination finding where the patient experiences pain upon palpation of the right upper quadrant during inspiration. This sign is indicative of gallbladder inflammation and is often associated with cholecystitis. Therefore, it is a manifestation of the condition.
C. Green colored stool is not typically associated with cholecystitis. Stool color can vary based on diet, medications, or the presence of bile. While pale or clay-colored stools can occur with obstruction of bile flow (such as with gallstones), green stools are more often related to rapid transit through the intestines, dietary factors, or certain infections rather than cholecystitis itself.
D. Nausea and vomiting are common symptoms of cholecystitis. Patients may experience these symptoms due to the inflammation and irritation of the gastrointestinal tract associated with gallbladder issues.
