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. A nurse preparing to assist with data collection of the abdomen asks the client to void and then assists the client into a supine position. Which primary finding does the nurse expect to note on percussing all four quadrants of the abdominal cavity?
- A. Dullness
- B. Tympany
- C. Borborygmus
- D. Hyperresonance
Correct answer: B
Rationale: The nurse expects to primarily note tympany when percussing the abdomen. Tympany should predominate because air in the intestines rises to the surface when the client is in a supine position. Dullness is usually heard over a distended bladder, adipose tissue, fluid, or a mass. Borborygmus, which refers to hyperperistalsis, is typically heard on auscultation, not percussion. Hyperresonance is present with gaseous distention, not the typical finding when percussing all four quadrants of the abdomen.
3. When should rehabilitation services begin?
- A. when the client enters the health care system.
- B. after the client requests rehabilitation services
- C. after the client's physical condition stabilizes.
- D. when the client is discharged from the hospital.
Correct answer: A
Rationale: Rehabilitation services should begin when the client enters the health care system to ensure early intervention and optimal outcomes. Initiating rehabilitation early can help prevent complications, improve recovery, and enhance overall well-being. Option B is incorrect because waiting for the client to request services may lead to delays in starting treatment, potentially affecting the recovery process. Option C is incorrect as rehabilitation can often commence even when the client's physical condition is not fully stabilized, as early intervention is crucial for progress. Option D is incorrect as beginning rehabilitation only after hospital discharge may not be ideal, as early intervention within the healthcare system is preferred for a more effective recovery journey.
4. Which of the following foods is a complete protein?
- A. corn
- B. eggs
- C. peanuts
- D. sunflower seeds
Correct answer: B
Rationale: Eggs are considered a complete protein because they contain all nine essential amino acids required by the human body. In contrast, corn, peanuts, and sunflower seeds are incomplete proteins as they lack one or more essential amino acids. Corn, although a staple food for many cultures, is deficient in the amino acids lysine and tryptophan. Peanuts are low in the amino acid methionine, and sunflower seeds are low in lysine. Therefore, eggs are the correct answer as a complete protein source.
5. Which of the following vaccines contains a live virus?
- A. varicella
- B. IPV
- C. DTaP
- D. hepatitis B
Correct answer: A
Rationale: The correct answer is varicella. Varicella vaccine contains a live, weakened form of the varicella-zoster virus. Choice B, IPV (inactivated poliovirus vaccine), is an inactivated vaccine, not a live virus vaccine. Choices C and D, DTaP (diphtheria, tetanus, and acellular pertussis vaccine) and hepatitis B vaccine, respectively, do not contain live viruses. Varicella is the only live virus vaccine among the options.
