Nursing Elites

1. One of the most critical needs of the infant is control of body temperature. The nurse caring for a newborn warms all equipment that comes in direct contact with the newborn to help prevent which type of heat loss?

• A. Convection
• B. Evaporation
• C. Conduction
• D. Radiation

Correct answer: C

Rationale: The correct answer is Conduction (choice C). Conduction heat loss occurs when the newborn’s skin comes into direct contact with a cooler surface, so warming equipment helps prevent this. Choice A, Convection, is the transfer of heat through air or water currents, not direct contact. Choice B, Evaporation, is the loss of heat through moisture on the skin evaporating, not direct contact. Choice D, Radiation, is the transfer of heat in the form of waves or particles, not direct contact.

2. A thorough systemic physical assessment is necessary in the extremely low-birth-weight (ELBW) infant to detect what?

• A. Weight gain reflective of fluid retention
• B. Difficulties in maternal-child attachment
• C. Subtle changes that may be indicative of an underlying problem
• D. Changes in Apgar score over the first 24 hours of life

Correct answer: C

Rationale: In extremely low-birth-weight (ELBW) infants, a thorough systemic physical assessment is crucial to detect subtle changes that may indicate an underlying problem. These infants are highly vulnerable and may show signs of stress through changes in feeding behavior, activity, color, oxygen saturation, or vital signs. Monitoring weight in ELBW infants primarily reflects genitourinary function rather than fluid retention. Difficulties in maternal-child attachment are important but are usually assessed during parental visits and are not the primary focus of a systemic physical assessment. Changes in the Apgar score are used immediately after birth to assess the transition to extrauterine life and are not as relevant in the following 24 hours to detect ongoing subtle issues.

3. The parents of a 4-month-old infant tell the nurse that they are getting a microwave oven and will be able to heat the baby’s formula faster. What should the nurse recommend?

• A. Heat only 8 oz or more.
• B. Do not heat a plastic bottle in a microwave oven.
• C. Leave the bottle top uncovered to allow heat to escape.
• D. Shake the bottle vigorously for at least 30 seconds after heating.

Correct answer: B

Rationale: Heating formula in a plastic bottle in the microwave can cause uneven heating and release harmful chemicals from the plastic.

4. The parent of a 3-month-old infant is concerned because the infant is not able to sit independently. How should the nurse respond to this parent's concern?

• A. Sitting ability and the age of first tooth eruption are not correlated.
• B. Most infants sit steadily at 4 months.
• C. Most infants sit steadily at 3 months.
• D. Most infants do not sit steadily until 6-8 months.

Correct answer: D

Rationale: The correct answer is D because sitting steadily typically occurs closer to 6-8 months of age, not 3 or 4 months. Choice A is incorrect because sitting ability and the age of first tooth eruption are not related. Choice B and C are incorrect as most infants do not sit steadily at 3 or 4 months, and it is more common for infants to achieve this milestone around 6-8 months.

5. A four-year-old boy is admitted to the hospital with leg pain and fever. He is pale-looking and has bruises over various areas of his body. The physician suspects acute lymphoblastic leukemia (ALL). Which test would be used to confirm the diagnosis?

• A. Bone marrow aspirate
• B. Red blood cell count
• C. Lumbar puncture
• D. Bone scan

Correct answer: A

Rationale: A bone marrow aspirate is the definitive test to confirm acute lymphoblastic leukemia (ALL) in this case. It allows for the examination of leukemic cells in the bone marrow, providing a direct assessment of the disease. Red blood cell count (Choice B) is not specific for diagnosing leukemia but may show anemia commonly seen in leukemia patients. Lumbar puncture (Choice C) is used to assess central nervous system involvement, not primarily for confirming ALL. Bone scan (Choice D) is not a standard diagnostic test for ALL and is mainly used for evaluating bone metastases in other conditions.
