ATI Pharmacology Proctored Exam 2023
1. 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?
- A. Fomepizole
- B. Naloxone
- C. Phytonadione
- D. Diphenhydramine
Correct answer: D
Rationale: The client's symptoms of face spasms after receiving Prochlorperazine indicate acute dystonia, a known side effect. Diphenhydramine is commonly administered to manage extrapyramidal symptoms, such as muscle spasms, caused by medications like Prochlorperazine. Therefore, the nurse should anticipate a prescription for Diphenhydramine to alleviate the client's symptoms. Choices A, B, and C are incorrect because Fomepizole is used in methanol or ethylene glycol poisoning, Naloxone is an opioid antagonist used in opioid overdose, and Phytonadione is vitamin K, used to reverse the effects of certain blood thinners.
2. A client is receiving epoetin alfa to treat anemia. Which of the following findings should the nurse monitor?
- A. Leukocytosis
- B. Hypertension
- C. Hyperkalemia
- D. Fever
Correct answer: B
Rationale: The nurse should monitor the client for hypertension when receiving epoetin alfa. Epoetin alfa stimulates red blood cell production, which can lead to increased blood pressure. Monitoring blood pressure is crucial to detect and manage hypertension promptly. Leukocytosis refers to an increased white blood cell count and is not directly related to epoetin alfa treatment. Hyperkalemia is an elevated potassium level, which is not a common adverse effect of epoetin alfa. Fever is not a typical finding associated with epoetin alfa therapy.
3. Which of the following is classified as a class IA Sodium Channel blocker?
- A. Quinidine
- B. Disopyramide
- C. Aminodarone
- D. Propafenone
Correct answer: A
Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.
4. When educating a client prescribed Rifampin, which instruction should the nurse provide?
- A. Expect orange discoloration of urine.
- B. Take the medication with food.
- C. Increase your intake of dairy products.
- D. Discontinue the medication if you experience itching.
Correct answer: A
Rationale: The correct instruction for a client prescribed Rifampin is to expect orange discoloration of urine. Rifampin is known to cause harmless discoloration of bodily fluids, including urine, which is a common side effect of this medication. It is important for the nurse to educate the client about this expected side effect to prevent unnecessary concern or discontinuation of the medication. Choices B, C, and D are incorrect because Rifampin does not require specific dietary considerations like taking it with food or increasing dairy intake. Furthermore, itching is not a common side effect that would necessitate immediate discontinuation of Rifampin.
5. 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.
