Nursing Elites

1. When drawing blood from the diabetic patient for a glycosylated hemoglobin (HBA1c) test, the nurse explains to the woman that the test is used to determine:

• A. The highest glucose level in the past week.
• B. Her insulin levels.
• C. Glucose levels over the past three months.
• D. Her usual fasting glucose level.

Correct answer: C

Rationale: The glycosylated hemoglobin (HBA1c) test reflects the average blood sugar levels over the past three months. It provides a more comprehensive view of the individual's glucose control compared to a single point-in-time measurement like a fasting glucose level or the highest glucose level in the past week. Choice A is incorrect because it focuses on a single high glucose level rather than the overall control over a period. Choice B is incorrect as HBA1c is not a test for insulin levels. Choice D is incorrect as the HBA1c test does not reflect a single fasting glucose level but rather an average over a more extended period.

2. The word hormone is derived from the Greek 'hormao' meaning 'I excite or arouse.' Hormones communicate this effect through their unique chemical structures recognized by specific receptors on their target cells, their patterns of secretion, and their concentrations in the general or local circulation. Which of the following is NOT a function of hormones?

• A. Producing new offspring
• B. Promoting growth and enhancing beauty
• C. Maintaining body temperature
• D. Fighting infections

Correct answer: A

Rationale: Hormones play a crucial role in various bodily functions such as regulating metabolism, growth, and maintaining homeostasis. However, producing new offspring involves reproductive processes controlled by other systems in the body, not directly by hormones.

3. Which of the following is not an infectious cause of diarrhea?

• A. Allergy
• B. Bacteria
• C. Parasite
• D. Virus

Correct answer: A

Rationale: The correct answer is A: Allergy. Allergy is not an infectious cause of diarrhea. Diarrhea caused by bacteria, parasites, and viruses is due to infection, while an allergy triggers an immune response that can lead to diarrhea but is not caused by an infectious agent. Choices B, C, and D are incorrect because bacteria, parasites, and viruses are known infectious causes of diarrhea, resulting from infections by these microorganisms.

4. What should be the drop rate per minute using a drop factor of 20 drops/ml?

• A. 19 drops/min
• B. 23 drops/min
• C. 36 drops/min
• D. 46.7 drops/min

Correct answer: A

Rationale: To calculate the drop rate per minute when using a drop factor of 20 drops/ml, you simply divide 60 (minutes) by the drop factor (20 drops/ml), giving you 3. Therefore, the drop rate per minute would be 3 drops x 20 drops/ml = 60 drops/min. However, since the question asks for the drop rate using a 20 drops/ml factor, the correct answer is slightly less than 60. By rounding down, the closest option is 19 drops/min, which is the correct calculation when considering the drop factor.

5. The instructor is teaching a group of new mothers about infant care. Which statement indicates that further teaching is needed?

• A. I should put my baby to sleep on their back.
• B. I can give my baby water if they seem thirsty.
• C. Breastfeeding provides all the nutrients my baby needs.
• D. I should burp my baby after each feeding.

Correct answer: B

Rationale: The correct answer is B. Newborns do not need additional water as breast milk or formula provides all the necessary hydration. Giving water to infants can be harmful and is not recommended as it can interfere with the balance of electrolytes in their bodies. Choice A is correct as placing babies on their back for sleep is the recommended safe sleeping position. Choice C is also correct as breastfeeding does provide all the essential nutrients for babies. Choice D is correct as burping the baby after each feeding helps prevent discomfort from trapped air.
