ATI Pharmacology Proctored Exam 2023 Questions
Question 1 of 5
A client has a new prescription for Nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?
Correct Answer: B
Rationale: The correct administration of Nitroglycerin sublingual tablets involves taking one tablet at the onset of chest pain and repeating every 5 minutes for up to three doses. If the pain persists after three doses, emergency medical services should be contacted for further evaluation and management.
Question 2 of 5
A client has a new prescription for Losartan. Which of the following laboratory values should the nurse monitor?
Correct Answer: A
Rationale: Losartan, an angiotensin II receptor blocker (ARB), can cause hyperkalemia by affecting the renin-angiotensin-aldosterone system. Monitoring serum potassium levels is crucial to detect and manage any potential hyperkalemia, which can lead to serious cardiac arrhythmias.
Question 3 of 5
A client who received Prochlorperazine 4 hours ago reports spasms of his face. The nurse should anticipate a prescription for which of the following medications?
Correct Answer: D
Rationale: An adverse effect of prochlorperazine is acute dystonia, which is evidenced by spasms of the muscles in the face, neck, and tongue. Diphenhydramine is used to suppress extrapyramidal effects of prochlorperazine, making it the most appropriate choice to address the client's spasms.
Question 4 of 5
A healthcare provider is reviewing the health care record of a client who reports urinary incontinence and asks about a prescription for Oxybutynin. The healthcare provider should recognize that Oxybutynin is contraindicated in the presence of which of the following conditions?
Correct Answer: D
Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma due to the potential to worsen the condition by further elevating intraocular pressure, leading to harm. Therefore, choosing option D, Glaucoma, as the correct answer is essential for the client's safety and to prevent exacerbation of their eye condition.
Question 5 of 5
While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
Correct Answer: C
Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation.
