Question 1 of 5
A 16-year-old student has a long history of bronchial asthma and has experienced several severe asthmatic attacks during the school year. The school nurse is required to administer 0.2 mL of 1/1000 solution of epinephrine SC during an asthma attack. How does the school nurse evaluate the effectiveness of this intervention?
Correct Answer: C
Rationale: A side effect of epinephrine is fatal ventricular fibrillation owing to its effects on cardiac stimulation. Medications used to treat asthma are designed to decrease bronchospasm, not to increase expectorate of secretions. Epinephrine decreased inspiratory difficulty by stimulating α-, β1, and β2-receptors causing sympathomimetic stimulation (e.g., bronchodilation). The person with asthma fights to inspire sufficient air thus increasing respiratory rate.
Question 2 of 5
The nurse is evaluating the client who was admitted eight hours ago for induction of labor. The following graph is noted on the monitor. Which action should be taken first by the nurse?
Correct Answer: C
Rationale: The most immediate action in cases of suspected fetal distress or hyperstimulation during labor induction with Pitocin is to stop the Pitocin infusion to reduce uterine stimulation and improve fetal oxygenation. Other actions like vaginal exams or pushing are inappropriate without further assessment, and positioning is secondary.
Question 3 of 5
The primary reason for sending a burn client home with a pressure garment, such as a Jobst garment, is that the garment:
Correct Answer: A
Rationale: Pressure garments apply uniform pressure to prevent or reduce hypertrophic scarring, which is critical during the recovery phase of burn care.
Question 4 of 5
The nurse is caring for a client with a recent stroke. Which position is most appropriate for this client?
Correct Answer: C
Rationale: Side-lying with the head elevated 30 degrees reduces intracranial pressure and promotes venous drainage in stroke clients, minimizing complications like cerebral edema. Supine, prone, or sitting positions may increase pressure or risk aspiration.
Question 5 of 5

B), A (
C), and E (
D) do not significantly affect homocysteine.
