ATI Pharmacology Exam Practice Questions
Question 1 of 5
The following drugs exert their principal effects by enzyme inhibition:
Correct Answer: D
Rationale: Selegiline inhibits monoamine oxidase-B, reducing dopamine breakdown. Others, like Atropine and Amlodipine, work via different pathways or receptor mechanisms.
Question 2 of 5
A patient diagnosed with cancer is scheduled to receive vincristine. Which nursing assessment will have the highest priority when providing care for this patient?
Correct Answer: D
Rationale: Vincristine is known to cause peripheral neuropathy, a common and potentially debilitating side effect. The nurse should prioritize assessing for signs of neuropathy, such as tingling, numbness, or weakness in the extremities. Alopecia, while distressing, is not as critical as neuropathy, which can affect the patient's mobility and quality of life. Vincristine does not typically cause significant changes in digoxin or phenytoin levels, making these assessments less relevant. Early detection of neuropathy allows for dose adjustments or supportive interventions to minimize long-term damage.
Question 3 of 5
A nurse is completing discharge teaching for a client who has a new prescription for transdermal patches. Which of the following statements should the nurse identify as an indication that the client understands the instructions?
Correct Answer: B
Rationale: Rotating the application sites of transdermal patches is important to prevent skin irritation and enhance absorption efficiency. This practice helps to minimize skin irritation and allows the skin to recover between applications. By rotating the sites weekly, the client can ensure optimal medication delivery and reduce the risk of skin reactions at any specific application site. This indicates that the client understands the importance of proper patch placement and skin care.
Question 4 of 5
Which of the following should the nurse include when providing dietary teaching for the patient receiving warfarin (Coumadin) therapy?
Correct Answer: A
Rationale: The nurse should include the instruction to avoid drinking large amounts of green tea when providing dietary teaching for a patient receiving warfarin (Coumadin) therapy because green tea contains vitamin K, which can interfere with the anticoagulant effects of warfarin. Maintaining consistent intake of vitamin K is important to ensure the effectiveness of warfarin therapy. Therefore, it is recommended for patients on warfarin to consume a consistent amount of vitamin K-containing foods and avoid sudden, significant changes in their intake.
Question 5 of 5
A 56-year-old man with chronic pain injects himself with morphine, which he obtained from a friend who is an emergency department nurse. He is found dead in his apartment by the police. What is the most likely cause of death?
Correct Answer: C
Rationale: Morphine overdose typically causes respiratory depression , leading to hypoxia and death, common in illicit use. Heart failure , hepatitis , edema , and embolism (E) are less likely. Opioid-induced apnea explains his sudden demise.
