Nursing Elites

1. At which age do most infants begin to fear strangers?

• A. 2 months
• B. 4 months
• C. 6 months
• D. 12 months

Correct answer: C

Rationale: Fear of strangers typically begins around 6 months as infants start recognizing familiar and unfamiliar faces, which is part of their social development.

2. 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.

3. The charge nurse in the pediatric unit is teaching nursing students about pyloric stenosis. A student asks what causes pyloric stenosis. How should the nurse respond?

• A. One portion of the intestines invaginates or telescopes into another
• B. Hypertrophy of the circular pylorus muscle
• C. Relaxed cardiac sphincter
• D. Absent ganglion cells in the colon

Correct answer: B

Rationale: Pyloric stenosis is caused by the hypertrophy (thickening) of the circular muscle of the pylorus, leading to obstruction. Choice A is incorrect as it describes intussusception, not pyloric stenosis. Choice C is incorrect as a relaxed cardiac sphincter is related to gastroesophageal reflux. Choice D is incorrect as it describes Hirschsprung's disease, not pyloric stenosis.
