Nursing Elites

1. How often should the intravenous tubing on total parenteral nutrition solutions be changed?

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

Correct answer: A

Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.

2. After undergoing gastric resection, which of the following meals is most likely to cause rapid emptying of the stomach?

• A. a high-protein meal
• B. a high-fat meal
• C. a large meal regardless of nutrient content
• D. a high-carbohydrate meal

Correct answer: D

Rationale: After gastric resection, meals high in carbohydrates are more likely to cause rapid emptying of the stomach. Carbohydrates stimulate the release of gastrin, which accelerates gastric emptying. In contrast, high-fat and high-protein meals tend to delay gastric emptying. While a large meal can slow down gastric emptying, the specific nutrient content, such as high carbohydrates, plays a significant role in promoting rapid emptying. Therefore, a high-carbohydrate meal is the correct choice as it is most likely to lead to rapid gastric emptying compared to the other options.

3. 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.

4. A multigravida pregnant woman asks the nurse when she will start to feel fetal movements. Around which week of gestation does the nurse tell the mother that fetal movements are first noticed?

• A. 16 weeks
• B. 6 weeks
• C. 8 weeks
• D. 12 weeks

Correct answer: A

Rationale: Fetal movements (quickening) are first noticed by multigravida pregnant women at 16 to 20 weeks of gestation and gradually increase in frequency and strength. This is when the mother typically begins to feel the baby's movements. Choices B, C, and D are incorrect because fetal movements are not felt as early as 6, 8, or 12 weeks of gestation. At 6 weeks, the embryo's movements are not yet strong enough to be felt by the mother. By 8 weeks, the movements are still too subtle to be perceived. At 12 weeks, although fetal movements start, they are usually not strong enough to be felt by the mother.

5. A client asks the nurse what risk factors increase the chances of getting skin cancer. The risk factors include all except:

• A. light or fair complexion.
• B. exposure to sun for extended periods of time.
• C. certain diet and foods.
• D. history of bad sunburns.

Correct answer: C

Rationale: The correct answer is 'certain diet and foods.' Risk factors that increase the chances of getting skin cancer include having a light or fair complexion, a history of bad sunburns, personal or family history of skin cancer, outdoor activities with sun exposure, exposure to X-rays or radiation, exposure to certain chemicals, repeated trauma or injury resulting in scars, age over 50, male gender, and living in specific geographic locations. These factors can contribute to the development of skin cancer. Avoiding exposure to the sun, using protective clothing and sunscreen, and regular skin inspections are key preventive measures. Choice C, 'certain diet and foods,' is incorrect as diet is not a primary risk factor for skin cancer. Options A, B, and D are all valid risk factors associated with an increased risk of developing skin cancer.
