Pharmacology HESI 55 Questions 2023
1. A client has been diagnosed with open-angle glaucoma. The healthcare provider prescribes pilocarpine 1% eye drops. The nurse explains that which action of this drug makes it a useful treatment for the client's condition?
- A. The ciliary muscle contracts, increasing the outflow of aqueous humor in the eye.
- B. Ciliary muscles are paralyzed to decrease accommodation.
- C. Bilateral mydriasis with cycloplegia is accomplished.
- D. The production of aqueous humor in the eyes is decreased.
Correct answer: A
Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye. Choice A is correct because the contraction of the ciliary muscle increases the outflow of aqueous humor, aiding in the treatment of open-angle glaucoma. Choices B, C, and D are incorrect because they do not describe the mechanism of action of pilocarpine in treating glaucoma.
2. A client diagnosed with a herniated disc is prescribed hydrocodone/acetaminophen 10 mg/300 mg prn every 4 to 6 hours. As the practical nurse (PN) enters the client's room to administer the requested medication, the client is seen talking and laughing with visiting family. What action should the PN take?
- A. Hold the pain medication until after the visitors leave.
- B. Notify the healthcare provider of the client's drug-seeking behavior.
- C. Administer analgesia as requested by the client.
- D. Inform the client that the medication is not needed based on their behavior.
Correct answer: C
Rationale: The correct action for the PN in this situation is to administer the analgesia as requested by the client. Pain management is based on the client's self-report of pain, which is the most reliable indicator of pain intensity. Analgesics should be given promptly when pain occurs and before it worsens. Following the administration of medication, the PN should discuss the situation with the charge nurse for further guidance or assessment.
3. A client with a history of deep vein thrombosis is prescribed rivaroxaban. The nurse should monitor for which potential adverse effect?
- A. Increased risk of bleeding
- B. Decreased risk of bleeding
- C. Increased risk of infection
- D. Decreased risk of infection
Correct answer: A
Rationale: When a client with a history of deep vein thrombosis is prescribed rivaroxaban, the nurse should monitor for signs of bleeding as rivaroxaban increases the risk of bleeding. Common adverse effects of rivaroxaban include bleeding events, such as easy bruising, prolonged bleeding from cuts, or blood in the urine or stool. It is crucial for the nurse to assess for these signs to prevent complications and ensure the client's safety. Choices B, C, and D are incorrect because rivaroxaban does not decrease the risk of bleeding, increase the risk of infection, or decrease the risk of infection. Monitoring for bleeding is essential due to the anticoagulant properties of rivaroxaban.
4. A client is prescribed nitroglycerin sublingual tablets. The practical nurse should reinforce which instruction?
- A. Store the tablets in a cool, dry place.
- B. Take one tablet every 5 minutes until pain is relieved, up to three tablets.
- C. Swallow the tablets whole.
- D. Chew the tablets for faster relief.
Correct answer: A
Rationale: Nitroglycerin sublingual tablets are sensitive to heat and moisture, so they should be stored in a cool, dry place to maintain their efficacy. Storing them in a cool, dry place helps prevent degradation of the medication. Choice B is incorrect because nitroglycerin tablets should be taken as directed by the healthcare provider to avoid potential overdose or adverse effects. Choice C is incorrect because sublingual tablets should be placed under the tongue to dissolve and be absorbed, not swallowed, to ensure their quick action. Choice D is incorrect because sublingual tablets should not be chewed; they are meant to be absorbed through the tissues under the tongue, and chewing them may alter their effectiveness.
5. A client is prescribed amitriptyline for depression. The practical nurse (PN) should monitor for which potential side effect?
- A. Insomnia
- B. Weight loss
- C. Dry mouth
- D. Increased appetite
Correct answer: D
Rationale: The correct answer is 'D: Increased appetite.' Amitriptyline, a tricyclic antidepressant, is known to commonly cause increased appetite, leading to weight gain. Monitoring for increased appetite is crucial as it can impact the client's overall health and well-being. Choice A, 'Insomnia,' is less likely as amitriptyline is more associated with sedative effects. Choice B, 'Weight loss,' is incorrect as weight gain is a more common side effect. Choice C, 'Dry mouth,' is a potential side effect of amitriptyline, but it is not directly related to increased appetite, which is the primary concern in this case.
