Nursing Elites

1. What test is used to screen for carbohydrate malabsorption?

• A. Stool pH
• B. Urine ketones
• C. C urea breath test
• D. ELISA stool assay

Correct answer: A

Rationale: Stool pH testing is used to screen for carbohydrate malabsorption. A low pH indicates the presence of unabsorbed carbohydrates, which are fermented by bacteria, leading to acidic stool.

2. What may be a clinical manifestation of failure to thrive (FTT) in a 13-month-old include?

• A. Irregularity in activities of daily living
• B. Preferring solid food to milk or formula
• C. Weight that is at or below the 10th percentile
• D. Appropriate achievement of developmental landmarks

Correct answer: C

Rationale: FTT is characterized by weight that falls below the 10th percentile, often accompanied by delayed developmental milestones and poor feeding habits. Regularity in activities and preference for solid food over milk or formula are less commonly associated with FTT.

3. Nurses should be alert for increased fluid requirements in which circumstance?

• A. Fever
• B. Mechanical ventilation
• C. Congestive heart failure
• D. Increased intracranial pressure

Correct answer: A

Rationale: Fever increases metabolic rate, leading to insensible water loss, thus requiring increased fluid intake. Mechanical ventilation, CHF, and increased intracranial pressure generally require fluid restriction rather than increased fluid intake.

4. The nurse is performing an otoscopic examination on a child. Which are normal findings the nurse should expect? (Select all that apply.)

• A. All below
• B. A well-defined light reflex
• C. A small, round, concave spot near the center of the drum
• D. The tympanic membrane is a nontransparent grayish color

Correct answer: A

Rationale: A well-defined light reflex, a small concave spot, and a grayish, nontransparent tympanic membrane are normal findings during an otoscopic examination in a child.

5. 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.
