A 10-month-old infant is diagnosed with gastroesophageal reflux. An esophageal (pH) probe monitor is ordered. What explanation for the purpose of the esophageal probe should the nurse provide to the parents?
- A. Assist in the passage of formula through the esophagus
- B. Identify the number of reflux episodes that are occurring
- C. Determine the time it takes for the stomach to empty its contents
- D. Monitor the pH within the stomach
Correct Answer: B
Rationale: The correct answer is B. The esophageal pH probe is used to identify the frequency and severity of reflux episodes by measuring the pH in the esophagus. Choice A is incorrect because the probe does not assist in the passage of formula through the esophagus. Choice C is incorrect as determining the time it takes for the stomach to empty its contents would require a different procedure. Choice D is incorrect as the esophageal pH probe monitors the pH in the esophagus, not the stomach.

The nurse is caring for a child with sickle cell anemia with the following order: Morphine Sulfate 2 mg IV every 24 hours. Morphine Sulfate is available in 10 mg/1mL. How many mL should the nurse administer?
- A. 0.2 mL
- B. 0.5 mL
- C. 1 mL
- D. 2 mL
Correct Answer: A
Rationale: To administer 2 mg of Morphine Sulfate when the concentration is 10 mg/mL, the nurse should administer 0.2 mL (2 mg / 10 mg/mL = 0.2 mL). Choice B, 0.5 mL, is incorrect because it is the result of dividing 2 mg by 4 mg/mL instead of 10 mg/mL. Choice C, 1 mL, is incorrect as it would be the result of dividing 2 mg by 2 mg/mL. Choice D, 2 mL, is incorrect as it would be the result of dividing 2 mg by 1 mg/mL.
A mother reports to the nurse that her 6-year-old child is highly active, irritable, irregular in habits, and adapts slowly to new routines, people, or situations. Which pattern of temperament would best describe the child?
- A. The 'easy' child
- B. The 'difficult' child
- C. The 'slow-to-warm-up' child
- D. The 'fast-to-warm-up' child
Correct Answer: B
Rationale: The 'difficult' child is the best way to describe the child in this scenario. This temperament is characterized by high activity levels, irritability, irregular habits, and difficulty adapting to changes. Choice A, the 'easy' child, is known for being generally positive and adaptable. Choice C, the 'slow-to-warm-up' child, typically needs time to adapt to new situations but is not necessarily highly active or irritable. Choice D, the 'fast-to-warm-up' child, adapts quickly to new situations, which contrasts with the child's slow adaptation mentioned in the scenario.
