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 A

Explanation

A. Sudden and severe abdominal pain is a classic sign of gastrointestinal perforation. When an ulcer perforates, it allows gastric contents to spill into the abdominal cavity, leading to irritation and inflammation of the peritoneum (peritonitis). This can cause acute, intense pain that often starts suddenly and is typically localized to the area of the perforation.
B. Hyperactive bowel sounds may occur due to irritation or inflammation in the gastrointestinal tract but are not a definitive indicator of perforation. In fact, with perforation, bowel sounds may be diminished or absent due to the associated peritonitis and ileus that can occur after a perforation.
C. Bradycardia (a slow heart rate) is not a typical finding associated with gastrointestinal perforation. In fact, perforation often leads to tachycardia (increased heart rate) as a compensatory response to pain, shock, or blood loss. Bradycardia may indicate other issues but is not directly linked to perforation.
D. Increased blood pressure is also not typically associated with gastrointestinal perforation. Patients may experience hypotension due to shock from blood loss and infection resulting from perforation.

A. GERD B. Paralytic ileus C. Diarrhea D. Nausea and vomiting

Correct Answer is D

Explanation

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.
