1. The healthcare provider is assessing an infant and notes that the infant's urine has a mousy or musty odor. What would the healthcare provider suspect?

• A. Maple syrup urine disease
• B. Tyrosinemia
• C. Phenylketonuria
• D. Trimethylaminuria

Correct answer: C

Rationale: Phenylketonuria (PKU) is suggested by a mousy or musty odor of the urine, caused by the inability to metabolize phenylalanine. Maple syrup urine disease (Choice A) is characterized by a sweet-smelling urine. Tyrosinemia (Choice B) presents with cabbage-like odor in the urine. Trimethylaminuria (Choice D) results in a fishy odor in the urine, breath, and sweat.

2. A group of students is reviewing information about the endocrine system in infants and children. The students demonstrate understanding of the information when they state:

• A. Endocrine glands begin developing during gestation.
• B. Endocrine glands are fully functional at birth.
• C. Infants may have difficulty regulating glucose and electrolytes.
• D. A child’s endocrine system plays a significant role in growth and development.

Correct answer: C

Rationale: The correct answer is C. Infants may have difficulty regulating glucose and electrolytes due to their immature endocrine systems. This can lead to issues such as hypoglycemia and electrolyte imbalances. Choice A is incorrect because endocrine glands actually begin developing early in gestation, not just in the third trimester. Choice B is incorrect as endocrine glands are not fully functional at birth; they continue to mature and develop after birth. Choice D is incorrect as a child's endocrine system has a significant impact on growth and development through the secretion of hormones that regulate various processes in the body, but it does not specifically address the difficulty in regulating glucose and electrolytes seen in infants.

3. After clearing the airway of a newborn who is not in distress, what is the most important action to take next?

• A. Administer free-flow oxygen
• B. Clamp and cut the cord
• C. Keep the newborn warm
• D. Obtain an APGAR score

Correct answer: C

Rationale: Keeping the newborn warm is crucial immediately after clearing the airway to prevent hypothermia, which can lead to complications in newborns. Administering free-flow oxygen is not necessary if the newborn is not in distress. Clamping and cutting the cord can be done after ensuring the newborn's warmth. Obtaining an APGAR score is important but can be done after ensuring the newborn is kept warm and stable.

4. A 4-year-old fell from a third-story window and landed on her head. She is semiconscious with slow, irregular breathing and bleeding from her mouth. After performing a jaw-thrust maneuver with simultaneous stabilization of her head, what should you do next?

• A. suction the oropharynx
• B. insert a nasopharyngeal airway
• C. initiate positive pressure ventilations
• D. place the patient in the recovery position

Correct answer: A

Rationale: In this scenario, the 4-year-old is presenting with signs of airway compromise due to the fall. After performing a jaw-thrust maneuver to open the airway while stabilizing the head to prevent further injury, the next step should be to suction the oropharynx. Suctioning helps to clear any blood or secretions from the mouth and throat, ensuring a clear airway for proper breathing. Inserting a nasopharyngeal airway or initiating positive pressure ventilations would be premature without first ensuring the airway is clear. Placing the patient in the recovery position is not indicated at this point as the focus should be on managing the airway.

5. Based on developmental norms for a 5-year-old child, a healthcare professional decides to withhold a scheduled dose of digoxin (Lanoxin) elixir and notify the healthcare provider. Below what apical pulse did the healthcare professional withhold the medication?

• A. 60 beats/min
• B. 70 beats/min
• C. 90 beats/min
• D. 100 beats/min

Correct answer: C

Rationale: For a 5-year-old child, an apical pulse below 90 beats/min is an indicator to withhold digoxin. Digoxin is a medication that affects the heart, and in pediatric patients, monitoring the pulse rate is crucial due to the risk of bradycardia (slow heart rate) as a potential side effect. In this case, an apical pulse of 90 beats/min or lower indicates a heart rate that may be too slow for a child of this age, warranting the withholding of digoxin and prompt notification of the healthcare provider. Choices A, B, and D are not within the critical range specified for withholding digoxin in a 5-year-old child and would not necessitate withholding the medication.
