What is the purpose of using cimetidine (Tagamet) for gastroesophageal reflux?
- A. The medication reduces gastric acid secretion.
- B. The medication neutralizes the acid in the stomach.
- C. The medication increases the rate of gastric emptying time.
- D. The medication coats the lining of the stomach and esophagus.
Correct Answer: A
Rationale: The correct answer is A. Cimetidine (Tagamet) is an H2 receptor antagonist that works by reducing gastric acid secretion. This action helps to decrease the acidity in the stomach, which in turn reduces the symptoms of gastroesophageal reflux. Choice B is incorrect because cimetidine does not neutralize acid but rather decreases its production. Choice C is incorrect as cimetidine does not affect the rate of gastric emptying time. Choice D is incorrect as cimetidine does not coat the lining of the stomach and esophagus but instead works to reduce gastric acid secretion.

A school-age child with celiac disease asks for guidance about snacks that will not exacerbate the disease. What snack should the nurse suggest?
- A. Pizza
- B. Pretzels
- C. Popcorn
- D. Oatmeal cookies
Correct Answer: C
Rationale: Popcorn is a safe snack for a child with celiac disease as it is naturally gluten-free. Other options like pizza, pretzels, and oatmeal cookies typically contain gluten unless specifically made with gluten-free ingredients, which can exacerbate celiac symptoms. Therefore, popcorn is the best option to suggest to the child to avoid any adverse effects on their condition.
The nurse is preparing to admit a 6-month-old child with gastroesophageal reflux disease. What clinical manifestations should the nurse expect to observe?
- A. Spitting up
- B. Bilious vomiting
- C. Failure to thrive
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D, as gastroesophageal reflux disease (GERD) in infants typically presents with symptoms such as spitting up, failure to thrive, excessive crying, and respiratory problems due to aspiration. Bilious vomiting is not a common symptom of GERD in infants and may indicate a different or more severe condition, such as intestinal obstruction or other gastrointestinal issues. Therefore, choices A, B, and C are all expected clinical manifestations of GERD in a 6-month-old child, making option D the correct answer.
What is the most appropriate action for a child with epistaxis?
- A. Have the child lie flat
- B. Pinch the nose and lean forward
- C. Apply a warm compress to the nose
- D. Encourage deep breathing
Correct Answer: B
Rationale: The most appropriate action for a child with epistaxis is to pinch the nose and lean forward. This technique helps stop the bleeding and prevent aspiration of blood. By applying pressure to the bleeding vessels and allowing the blood to drain out of the nostrils instead of being swallowed, the risk of nausea and airway obstruction is reduced. Having the child lie flat (Choice A) may lead to blood flowing down the throat, causing potential choking. Applying a warm compress (Choice C) is not typically recommended for epistaxis as cold compresses are more effective. Encouraging deep breathing (Choice D) is not directly related to managing epistaxis.
What is the most common cause of acute kidney injury in children?
- A. Dehydration
- B. Glomerulonephritis
- C. Hemolytic uremic syndrome
- D. Sepsis
Correct Answer: C
Rationale: Hemolytic uremic syndrome is the most common cause of acute kidney injury in children. While dehydration can lead to prerenal acute kidney injury, it is not the most common cause in children. Glomerulonephritis is a common cause of chronic kidney disease but not typically the most common cause of acute kidney injury in children. Sepsis can lead to acute kidney injury, but in children, hemolytic uremic syndrome is more prevalent.
What term describes the invagination of one segment of bowel within another?
- A. Atresia
- B. Stenosis
- C. Herniation
- D. Intussusception
Correct Answer: D
Rationale: Intussusception is the correct answer. It refers to the condition where one segment of the bowel folds into another, leading to an obstruction. Atresia (Choice A) is the absence or abnormal closure of a normal opening or tubular structure. Stenosis (Choice B) is the narrowing of a passage in the body. Herniation (Choice C) is the abnormal protrusion of an organ or tissue through a defect in its surrounding walls. Intussusception is a medical emergency commonly observed in infants and young children and necessitates prompt intervention to prevent severe complications.
