HESI Practice Test Pharmacology
1. A client who received a prescription for cyclosporine ophthalmic emulsion for dry eyes asks the practical nurse (PN) if it is safe to continue using artificial tears. What information should the PN provide?
- A. Avoid using artificial tears because they decrease the efficacy of cyclosporine.
- B. Discontinue the use of both products if transient blurring occurs after administration.
- C. Allow a 15-minute interval between the administration of cyclosporine and artificial tears.
- D. Discontinue the use of cyclosporine and artificial tears when tear production reaches a normal level.
Correct answer: C
Rationale: The correct answer is to allow a 15-minute interval between the administration of cyclosporine and artificial tears. Cyclosporine, an ophthalmic emulsion that increases tear production, can be used in conjunction with artificial tears as long as the products are administered 15 minutes apart. This interval helps to prevent any potential interactions between the two products and ensures optimal effectiveness of cyclosporine for treating dry eyes.
2. A client with a diagnosis of generalized anxiety disorder is prescribed venlafaxine. The nurse should instruct the client that this medication may have which potential side effect?
- A. Nausea
- B. Dry mouth
- C. Insomnia
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Nausea. Venlafaxine, a medication used for generalized anxiety disorder, can commonly cause nausea as a side effect. It is essential for clients to be aware of this potential side effect and advised to take the medication with food if nausea occurs. Choices B, C, and D are incorrect because dry mouth, insomnia, and headache are less commonly associated side effects of venlafaxine compared to nausea.
3. A client with a diagnosis of generalized anxiety disorder is prescribed alprazolam. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Alprazolam, a medication commonly used to treat anxiety disorders, can cause drowsiness as a common side effect. Clients should be advised not to drive or operate heavy machinery until they know how the medication affects them to ensure their safety.
4. A client is prescribed clopidogrel. The nurse should monitor for which potential side effect of this medication?
- A. Nausea and vomiting
- B. Bleeding or bruising
- C. Gastrointestinal bleeding
- D. Fatigue
Correct answer: C
Rationale: When a client is prescribed clopidogrel, the nurse should monitor for potential side effects related to bleeding due to its antiplatelet effect. Gastrointestinal bleeding is a severe side effect associated with clopidogrel use. Monitoring for signs of gastrointestinal bleeding, such as black, tarry stools or vomiting blood, is essential to prevent serious complications.
5. A client is receiving heparin to treat a deep vein thrombosis. The nurse should monitor which laboratory result to assist in evaluating the efficacy of the drug?
- A. Platelet count
- B. Prothrombin time
- C. Partial thromboplastin time
- D. Serum levels of protamine sulfate
Correct answer: C
Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.
