Nursing Elites

1. 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: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.

2. A child who weighs 10 kg is to receive Motrin 8 mg/kg po q4h prn for pain. The label reads 100 mg/5 mL. How much will you administer?

• A. 4 mL
• B. 2 mL
• C. 5 mL
• D. 3 mL

Correct answer: A

Rationale: To calculate the dosage, multiply the child's weight (10 kg) by the dosage (8 mg/kg) which equals 80 mg. Since the concentration is 100 mg/5 mL, to find out how much to administer, you need to determine how many 5 mL doses are in 80 mg. It will be 80 mg ÷ 100 mg * 5 mL = 4 mL. Therefore, the correct answer is 4 mL. Choice B, 2 mL, is incorrect because it does not account for the correct dosage calculation. Choice C, 5 mL, is incorrect as it does not consider the dosage based on the child's weight. Choice D, 3 mL, is incorrect as it does not reflect the accurate dosage calculation.

3. Which one of the following strategies might be recommended for an infant with failure to thrive (FTT) to increase caloric intake?

• A. Vary the schedule for routine activities on a daily basis.
• B. Be persistent through 10 to 15 minutes of food refusal.
• C. Avoid solids until after the bottle is well accepted.
• D. Use developmental stimulation by a specialist during feedings.

Correct answer: B

Rationale: Being persistent through 10 to 15 minutes of food refusal is recommended to help increase caloric intake in infants with FTT. Establishing a routine and using developmental stimulation can also be helpful, but the priority is ensuring adequate caloric intake.

4. The nurse suspects fluid overload in an infant receiving intravenous fluids. What clinical manifestation is suggestive of water intoxication?

• A. Oliguria
• B. Weight loss
• C. Irritability and seizures
• D. Muscle weakness and cardiac dysrhythmias

Correct answer: C

Rationale: Water intoxication can lead to cerebral edema, causing neurological symptoms such as irritability and seizures. Oliguria, weight loss, and muscle weakness are not typical signs of water intoxication.

5. Which immunization is recommended for all newborns?

• A. Hepatitis A vaccine
• B. Hepatitis B vaccine
• C. Hepatitis C vaccine
• D. Hepatitis A, B, and C vaccines

Correct answer: B

Rationale: The correct answer is B, the Hepatitis B vaccine. This vaccine is recommended for all newborns to prevent Hepatitis B infection, which can lead to chronic liver disease and liver cancer. The Hepatitis B vaccine is a crucial part of the routine immunization schedule for infants. Choices A, C, and D are incorrect because the recommended vaccine for newborns is specifically Hepatitis B, not Hepatitis A, Hepatitis C, or a combination of Hepatitis A, B, and C vaccines.
