Question 1 of 5
A 22-year-old female accounting student requires a daily cup of coffee upon arising and another cup as she finishes her first class of the day. She prefers to drink caffeinated products. Which of the following is the most plausible mechanism of action of this product?
Correct Answer: A
Rationale: Caffeine's stimulant effect in coffee relies on adenosine receptor blockade . By inhibiting adenosine's sedative action, caffeine increases alertness, fitting her routine. Option , decreasing cAMP, contradicts caffeine's phosphodiesterase inhibition, which raises cAMP. Option , decreasing cGMP, is unrelated. Option , stimulating phosphodiesterase, opposes caffeine's action. Option (E), calcium transport, isn't primary. Adenosine antagonism drives caffeine's wakefulness, supporting her daily use to combat fatigue during study.
Question 2 of 5
A client with gout is prescribed allopurinol (Zyloprim). Which laboratory value should the nurse monitor?
Correct Answer: A
Rationale: Allopurinol reduces uric acid production, treating gout by inhibiting xanthine oxidase. Monitoring serum uric acid tracks efficacy, ensuring levels drop (normal: 3.5-7.2 mg/dL) to prevent flares. BUN reflects kidney function, relevant but secondary unless damage exists. White blood cells and platelets aren't directly affected unless hypersensitivity occurs (rare). Uric acid is the therapeutic target, aligning with allopurinol's mechanism, critical in gout where hyperuricemia drives symptoms. Regular checks confirm treatment success, guiding dose adjustments, making A the key value to monitor.
Question 3 of 5
The nurse will administer medication to a school-age child. What is the preferred action by the nurse?
Correct Answer: A
Rationale: School-age kids (6-12) can understand drug purpose and side effects-e.g., 'This fights infection, you might feel sleepy'-fostering cooperation via cognitive growth. Threats like no recess breed resentment, not trust. Beverage choice helps but lacks education. Play delays, not enhances, administration. Teaching leverages development, improving adherence.
Question 4 of 5
A patient about to receive a morning dose of digoxin has an apical pulse of 53 beats/min. What will the nurse do next?
Correct Answer: D
Rationale: The correct action is to check the radial pulse for 1 full minute. When administering digoxin, it is important to assess the apical pulse before giving the medication. A heart rate of 53 beats/min is below the normal range, especially for a patient taking digoxin, which can slow heart rate further. The nurse should check the radial pulse for a full minute to verify the heart rate accurately and assess for any abnormalities. This step is crucial to ensure patient safety and prevent potential complications associated with bradycardia. In this situation, it is necessary to withhold the dose and notify the prescriber to determine the appropriate course of action based on the assessment findings.
Question 5 of 5
A child is receiving methylphenidate. The mother tells the nurse the patient is having trouble sleeping while on the medication. What is the best response by the nurse?
Correct Answer: A
Rationale: Methylphenidate, a stimulant used to treat ADHD, can cause insomnia if taken too late in the day. Administering the medication earlier in the day (before 4:00 pm) can help minimize sleep disturbances. Giving it at 8:00 pm (B) would worsen insomnia. Stopping the medication abruptly (C) is not recommended without consulting the healthcare provider. Diphenhydramine (D) is not a solution for stimulant-induced insomnia.
