1. Beta-adrenergic agonists such as Salbutamol are given to Reggie, a child with asthma. Such drugs are administered primarily to do which of the following?

• A. Dilate the bronchioles
• B. Reduce secondary infections
• C. Decrease postnasal drip
• D. Reduce airway inflammation

Correct answer: A

Rationale: Beta-adrenergic agonists like Salbutamol are used to dilate the bronchioles in asthma patients. This action helps in relieving bronchospasms and improving airflow to the lungs, making breathing easier for the individual. While reducing inflammation is an essential part of asthma management, beta-adrenergic agonists primarily work by relaxing the smooth muscles around the airways, leading to bronchodilation. Choices B, C, and D are incorrect because beta-adrenergic agonists are not primarily used to reduce secondary infections, decrease postnasal drip, or directly reduce airway inflammation in asthma patients.

2. A group of nursing students is discussing trends that influence pediatric health care today. The students' discussion focuses on which trends?

• A. Family-centered care
• B. Evidenced-based practice
• C. Nursing traditions
• D. A and B

Correct answer: D

Rationale: In pediatric health care, family-centered care and evidenced-based practice are crucial trends that impact care delivery. Family-centered care involves involving the family in decision-making and care planning, recognizing their role in the child's well-being. Evidenced-based practice ensures nursing interventions are based on the best available evidence to provide high-quality care to pediatric patients. Nursing traditions, though important, may not encompass the latest advancements in pediatric care. Therefore, choices A and B are correct as they represent current influential trends in pediatric health care.

3. 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.

4. 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.

5. The healthcare provider is assessing a newborn who had undergone vaginal delivery. Which of the following findings is least likely to be observed in a normal newborn?

• A. (+) Moro reflex
• B. Heart rate is 80 bpm
• C. Respirations are irregular
• D. Uneven head shape

Correct answer: B

Rationale: A heart rate of 80 bpm is least likely to be observed in a normal newborn. The normal heart rate range for a newborn is usually higher than 80 bpm, typically ranging from 120-160 bpm. The Moro reflex (choice A) is a normal newborn reflex, respirations being irregular (choice C) are expected due to the immature respiratory control center, and an uneven head shape (choice D) is common due to molding during vaginal delivery.
