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 with a chronic illness expresses frustration over their condition. What is the nurse's best response to support the client?
- A. Encourage joining a support group for emotional support
- B. Discuss the possibility of a cure in the future
- C. Suggest focusing on positive aspects of their life
- D. Validate their feelings and listen to their concerns
Correct answer: D
Rationale: The best response for the nurse to support a client expressing frustration over their chronic illness is to validate their feelings and listen to their concerns (Option D). This approach helps acknowledge the client's emotions, demonstrates empathy, and establishes a therapeutic relationship. By validating the client's feelings and actively listening to their concerns, the nurse offers a supportive environment for the client to express their frustrations. Choices A, B, and C are not the best responses in this situation. While joining a support group, discussing a cure, or focusing on positive aspects can be beneficial interventions, the immediate priority is to validate the client's feelings and provide a space for them to express their frustrations.
3. A client has active genital herpes simplex virus type 2. Which of the following medications should the nurse plan to administer?
- A. Metronidazole
- B. Penicillin
- C. Acyclovir
- D. Gentamicin
Correct answer: C
Rationale: Acyclovir is the antiviral medication specifically used to treat herpes simplex virus infections, including genital herpes caused by herpes simplex virus type 2. Metronidazole (Choice A) is an antibiotic used for different types of infections, but not for viral infections like herpes. Penicillin (Choice B) is an antibiotic effective against bacterial infections, not viruses like herpes. Gentamicin (Choice D) is an antibiotic mainly used to treat bacterial infections, not viral infections like herpes.
4. The nurse is leading a 'current events group' with chronic psychiatric clients. One group member states, 'Clara Barton was my nurse during my last hospitalization. She was a very mean nurse and wasn't nice to me.' Which response would be best for the nurse to make?
- A. 'Clara Barton was not your nurse.'
- B. 'What did she do to you that was so mean?'
- C. 'I didn't know that Clara Barton was a nurse.'
- D. 'Clara Barton started the American Red Cross.'
Correct answer: D
Rationale: (D) presents the reality of the situation in relation to American culture. The fact that Clara Barton was a nurse during the Civil War should be addressed on an individual basis. Since this is group therapy, the nurse would be illustrating the concept of universality. (A) is likely to promote defensiveness. (B and C) would support the delusion. Therefore, the most appropriate response is (D) as it provides factual information that can redirect the conversation in a constructive manner.
5. A client returns from surgery with two Penrose drains in place. Anticipating frequent dressing changes, what should the nurse use around the incision site?
- A. Montgomery straps
- B. Sterile gauze
- C. Adhesive tape
- D. Elastic bandages
Correct answer: A
Rationale: Montgomery straps are the correct choice in this scenario. They are specifically designed to secure dressings around drain sites, like Penrose drains, and are ideal for frequent dressing changes. Sterile gauze (Choice B) is commonly used for wound dressings but may not provide the best securement for drains. Adhesive tape (Choice C) can cause skin irritation and may not be suitable for securing drains. Elastic bandages (Choice D) are typically used for compression or support but are not appropriate for securing dressings around drain sites.
