Nursing Elites

1. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part water and one part concentrate.
• D. When using powdered formula, mix two parts water and one part powder.

Correct answer: A

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is essential for parents to be cautious when warming bottles in a microwave oven to prevent superheating of the milk. Choosing the defrost setting and checking the formula temperature before giving it to the baby helps avoid burns. Discarding partially used bottles after 24 hours when refrigerating formula is crucial as it reduces the risk of harmful bacterial growth. Mixing formula concentrate with water in a 1:1 ratio of one part concentrate to one part water ensures proper dilution of the formula. On the other hand, powdered formula should be mixed following the package instructions, typically using two parts water to one part powder. This accurate mixing ratio provides the necessary balance of nutrients for the baby. Adding fresh formula to partially used bottles can introduce pathogens that may harm the infant, underscoring the importance of discarding partially used bottles and preparing formula correctly. Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.

2. What is the primary theory that explains a family's concept of health and illness?

• A. Health Belief Model
• B. Education-School-Completing Factor
• C. Family Health Expert Factor
• D. Disconnected Family Factor

Correct answer: A

Rationale: The correct answer is the Health Belief Model. This model explains a family's concept of health and illness by focusing on readiness factors, perceived susceptibility, and seriousness of health problems, and positive motivation for wellness. The Health Belief Model is widely used in healthcare to understand and predict health behaviors. Choices B, C, and D are incorrect as they do not specifically address how a family perceives health and illness. The Health Belief Model is the most appropriate choice as it is specifically designed to explain individual and family beliefs and behaviors related to health and illness.

3. How often should the nurse change the intravenous tubing on total parenteral nutrition solutions?

• A. every 24 hours
• B. every 36 hours
• C. every 48 hours
• D. every 72 hours

Correct answer: A

Rationale: The correct answer is 'every 24 hours.' Changing the intravenous tubing on total parenteral nutrition solutions every 24 hours is crucial due to the high risk of bacterial growth. Bacterial contamination can lead to serious infections in patients receiving total parenteral nutrition. Choices B, C, and D are incorrect because waiting longer intervals between tubing changes increases the risk of bacterial contamination and infection, compromising patient safety. It is essential to maintain a strict 24-hour schedule to minimize the risk of complications associated with bacterial contamination.

4. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

5. A nurse assisting with data collection uses the back of the hand to feel the client's skin on both arms and notes that the skin is warm. The nurse makes which determination?

• A. The client has a fever.
• B. The skin temperature is normal.
• C. The client needs to drink additional fluids.
• D. The client needs to have the blanket removed.

Correct answer: B

Rationale: To assess skin temperature, the nurse would first note the temperature of their own hands. Then, using the backs of the hands to palpate the client's skin bilaterally, warmth suggests normal circulatory status if the skin is warm and the temperature is equal bilaterally. The hands and feet may feel slightly cooler in a cool environment. Options A, C, and D are incorrect responses. A warm skin temperature does not indicate a fever, the need for additional fluids, or the need to have the blanket removed.
