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. Which action should the nurse implement when taking an axillary temperature?

• A. Take the temperature through one layer of clothing
• B. Add a degree to the result when recording
• C. Place the tip of the thermometer under the arm in the center of the axilla
• D. Hold the child's arm away from the body while taking the temperature

Correct answer: C

Rationale: The correct technique involves placing the thermometer tip in the center of the axilla to ensure an accurate reading, with the arm held close to the body.

3. The nurse observes that a newborn is having problems after birth. What should indicate a tracheoesophageal fistula?

• A. Jitteriness
• B. Meconium ileus
• C. Excessive frothy saliva
• D. Increased need for sleep

Correct answer: C

Rationale: Excessive frothy saliva is a hallmark sign of tracheoesophageal fistula. The abnormal connection between the esophagus and trachea causes difficulty in swallowing, leading to an accumulation of saliva in the mouth. This symptom is crucial for early identification and management of tracheoesophageal fistula. Choices A, B, and D are incorrect as they are not specific indicators of tracheoesophageal fistula.

4. A child has a central venous access device for intravenous (IV) fluid administration. A blood sample is needed for a complete blood count, hemogram, and electrolytes. What is the appropriate procedure to implement for this blood sample?

• A. Perform a new venipuncture to obtain the blood sample.
• B. Interrupt the IV fluid and withdraw the blood sample needed.
• C. Withdraw a blood sample equal to the amount of fluid in the device, discard, and then withdraw the sample needed.
• D. Flush the line and central venous device with saline and then aspirate the required amount of blood for the sample.

Correct answer: C

Rationale: Withdrawing and discarding a sample equal to the amount of fluid in the device ensures that the blood drawn is not diluted by the IV fluids, providing accurate lab results.

5. At what age is it safe to give infants whole milk instead of commercial infant formula?

• A. 6 months
• B. 9 months
• C. 12 months
• D. 18 months

Correct answer: C

Rationale: Whole milk should not be introduced before 12 months because it lacks the necessary nutrients, such as iron, that infants need for proper growth and development.
