ATI Proctored Pharmacology Test
1. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?
- A. These medications work by blocking HIV entry into cells.
- B. These medications work by weakening the cell wall of the HIV virus.
- C. These medications work by inhibiting enzymes to prevent HIV replication.
- D. These medications work by preventing protein synthesis within the HIV cell.
Correct answer: C
Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.
2. What is the pharmacological action of metformin?
- A. Blocks stimulation of beta1 and beta2.
- B. Blocks vasoconstriction and aldosterone.
- C. Acts at many levels in the CNS to produce an anxiolytic effect.
- D. Decreases hepatic glucose production.
Correct answer: D
Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.
3. What is the first type of medication prescribed to prevent angina pain for a client?
- A. Beta blockers
- B. Alpha blockers
- C. Calcium channel blockers
- D. Organic nitrates
Correct answer: A
Rationale: Beta blockers are the first-line medication prescribed to prevent angina pain. They work by reducing the heart rate and blood pressure, decreasing the heart's demand for oxygen. This helps in preventing angina attacks by improving blood flow to the heart. Alpha blockers, calcium channel blockers, and organic nitrates are also used in angina treatment but are typically considered after beta blockers.
4. A client with Atrial Fibrillation is prescribed Dabigatran to prevent Thrombosis. Which medication is prescribed concurrently to treat an adverse effect of Dabigatran?
- A. Vitamin K1
- B. Protamine
- C. Omeprazole
- D. Probenecid
Correct answer: C
Rationale: Omeprazole, a proton pump inhibitor, is prescribed for clients taking dabigatran who experience abdominal pain and other gastrointestinal adverse effects associated with dabigatran use. Proton pump inhibitors help manage these symptoms effectively. Choice A, Vitamin K1, is incorrect as it antagonizes the activity of Dabigatran, counteracting its anticoagulant effect. Choice B, Protamine, is used to reverse the anticoagulant effects of heparin, not dabigatran. Choice D, Probenecid, is not typically used to treat adverse effects of dabigatran.
5. A client has a new prescription for rituximab. Which of the following findings should the nurse instruct the client to report?
- A. Dizziness
- B. Fever
- C. Urinary frequency
- D. Dry mouth
Correct answer: B
Rationale: The nurse should instruct the client to report fever. Fever can be an indication of an infection, a potential complication of rituximab therapy. Monitoring and reporting fever promptly can help in early intervention to prevent further complications. Dizziness, urinary frequency, and dry mouth are not typically associated with rituximab therapy and are less likely to be directly related to the medication. Therefore, they are not the priority findings to report in this scenario.
