Nursing Elites

1. 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.

2. The nurse is taking a sexual history on an adolescent girl. Which is the best way to determine whether she is sexually active?

• A. Ask her, "Are you sexually active?"
• B. Ask her, "Are you having sex with anyone?"
• C. Ask her, "Are you having sex with a boyfriend?"
• D. Ask both the girl and her parent if she is sexually active

Correct answer: A

Rationale: Directly asking the adolescent if she is sexually active is the most straightforward and respectful approach, ensuring privacy and fostering trust.

3. What procedure is most appropriate for the assessment of an abdominal circumference related to a bowel obstruction?

• A. Measuring the abdomen after feedings
• B. Marking the point of measurement with a pen
• C. Measuring the circumference at the symphysis pubis
• D. Using a new tape measure with each assessment to ensure accuracy

Correct answer: B

Rationale: Marking the point of measurement ensures consistent and accurate assessments of abdominal circumference, especially important in conditions like bowel obstruction where changes need to be monitored closely.

4. The nurse is selecting a site to begin an intravenous infusion on a 2-year-old child. The superficial veins on his hand and arm are not readily visible. What intervention should increase the visibility of these veins?

• A. Gently tap over the site.
• B. Apply a cold compress to the site.
• C. Raise the extremity above the level of the body
• D. Use a rubber band as a tourniquet for 5 minutes.

Correct answer: A

Rationale: Gently tapping over the site helps dilate the veins and increase visibility. Applying a cold compress or raising the extremity above the body level constricts the veins, making them harder to access. Prolonged tourniquet use can cause discomfort and venous congestion.

5. Rectal temperatures are indicated in which situation?

• A. In the newborn period
• B. Whenever accuracy is essential
• C. Rectal temperatures are never indicated
• D. When rapid temperature changes are occurring

Correct answer: B

Rationale: Rectal temperatures provide the most accurate measurement of core body temperature and are therefore indicated when accuracy is essential.
