Nursing Elites

1. A 12-month-old child presents to the clinic for a well visit after missing several appointments. The child began her immunization schedule but has missed several follow-up appointments and doses of immunizations. What is the most appropriate nursing intervention?

• A. Administer initial immunizations from the beginning of the schedule.
• B. The child cannot receive missed immunizations if the schedule is not followed and will not be vaccinated.
• C. The child should only receive the missed doses of immunizations based on the catch-up schedule.
• D. The child should receive double-strength immunizations at this well visit.

Correct answer: C

Rationale: Children who began primary immunization at the recommended age but fail to receive all the doses do not need to begin the series again but should receive only the missed doses. The child may receive missed vaccinations on a catch-up schedule per CDC guidelines.

2. Which electrolyte imbalance is a common concern in children with severe diarrhea?

• A. Hypernatremia
• B. Hypokalemia
• C. Hypercalcemia
• D. Hypomagnesemia

Correct answer: B

Rationale: Hypokalemia is the correct answer because it is a common concern in children with severe diarrhea. Diarrhea can lead to significant potassium loss, resulting in hypokalemia. Hypernatremia (Choice A) is less common in diarrhea as sodium concentration is usually diluted by the fluid loss. Hypercalcemia (Choice C) is not typically associated with severe diarrhea. Hypomagnesemia (Choice D) can occur but is not as common as hypokalemia in this scenario.

3. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed.
• B. Flexed posture favors heat loss.
• C. A large body surface area favors heat loss to the environment.
• D. A thick layer of subcutaneous fat provides excellent insulation.

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

4. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

5. 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.
