1. Beta-adrenergic agonists such as albuterol are given to Reggie, a child with asthma, to primarily 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 albuterol are bronchodilators that primarily work by relaxing and dilating the bronchioles, which helps to alleviate bronchoconstriction, a characteristic feature of asthma. This action leads to improved airflow and easier breathing for individuals experiencing asthma symptoms.

2. What is the term for a condition where there is a failure of the pituitary to produce sufficient growth hormone to sustain normal growth in children, with 80% of cases being idiopathic? It may present with familial patterns, affecting males more than females.

• A. Cretinism
• B. Growth hormone deficiency
• C. Hypothyroidism
• D. Precocious puberty

Correct answer: B

Rationale: Growth hormone deficiency refers to a condition where there is inadequate production of growth hormone by the pituitary gland. This results in impaired growth in children. While 80% of cases are of unknown cause (idiopathic), some may have familial patterns. It is more common in males than females. Cretinism is a condition of severe hypothyroidism during infancy, not related to growth hormone. Hypothyroidism is a disorder involving low thyroid hormone levels, and precocious puberty is the early onset of puberty. Therefore, the correct answer is 'Growth hormone deficiency.'

3. Which of the following parameters is the LEAST reliable when assessing the perfusion status of a 2-year-old child?

• A. Capillary refill time
• B. Presence of peripheral pulses
• C. Skin color and temperature
• D. Systolic blood pressure

Correct answer: D

Rationale: Systolic blood pressure is the least reliable parameter when assessing perfusion status in a 2-year-old child. In young children, blood pressure measurements can be variable, affected by factors like anxiety or crying. Capillary refill time, presence of peripheral pulses, and skin color and temperature are more reliable indicators of perfusion status in this age group.

4. A child newly diagnosed with diabetes mellitus has been stabilized with insulin injections daily. A nurse prepares a discharge teaching plan regarding the insulin. The teaching plan should reinforce which of the following concepts?

• A. Always store insulin vials in the refrigerator
• B. Adjust insulin dosage before exercise
• C. Presence of ketones in urine indicates a need for less insulin
• D. Systematically rotate injection sites

Correct answer: D

Rationale: Systematically rotating injection sites is crucial to prevent tissue damage and ensure optimal insulin absorption. This practice helps in preventing lipohypertrophy, a condition characterized by fat accumulation at injection sites, which can affect insulin absorption and lead to inconsistent blood glucose control. By rotating injection sites, the risk of skin and tissue damage is minimized, and insulin's effectiveness is maintained over time.

5. A child was brought to the emergency department with complaints of nausea, vomiting, and fruity-scented breath. The resident on duty diagnosed the child with diabetic ketoacidosis. Which of the following should the nurse expect to administer?

• A. Potassium chloride IV infusion.
• B. Dextrose 5% IV infusion.
• C. Ringer's Lactate.
• D. Normal saline IV infusion

Correct answer: D

Rationale: In diabetic ketoacidosis (DKA), there is a state of dehydration and electrolyte imbalance. Normal saline is the initial fluid of choice to help restore intravascular volume and improve electrolyte balance. It also helps to correct acidosis. Potassium chloride IV infusion is commonly added to the treatment regimen once kidney function is confirmed to prevent hypokalemia. Dextrose 5% IV infusion is not the first-line treatment for DKA as it can worsen hyperglycemia. Ringer's Lactate is not typically used as the initial fluid for managing DKA as it contains potassium and could worsen hyperkalemia.
