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. Which action should be taken to assess for analgesic tolerance in a client who is unable to communicate?
- A. Review the client's laboratory values for changes in peak and trough levels of the analgesic
- B. Prolong the interval between analgesic medication doses and monitor the client's vital signs
- C. Observe the client for the presence of pain behaviors before the next analgesic dose is due
- D. Ask family members to report behaviors suggesting that the client's pain has returned
Correct answer: C
Rationale: In clients who are unable to communicate, observing for pain behaviors is crucial in assessing analgesic tolerance. Changes in pain behaviors can indicate if the current analgesic regimen is effective or if tolerance has developed. Therefore, closely observing the client for pain behaviors before the next analgesic dose helps healthcare providers evaluate the client's response to pain management. Reviewing laboratory values may not directly reflect analgesic tolerance. Prolonging the interval between doses and monitoring vital signs may not provide direct information on analgesic tolerance. Relying solely on family members to report pain behaviors may not be as accurate or immediate as observing the client directly.
3. After receiving the third dose of a new oral anticoagulant prescription, which action should the nurse implement? Select all that apply.
- A. Notify the healthcare provider of the finding
- B. Provide a PRN NSAID for gum discomfort
- C. Review the most recent coagulation lab values
- D. Complete a medication variance report
Correct answer: C
Rationale: Reviewing the most recent coagulation lab values is crucial after receiving multiple doses of a new oral anticoagulant to ensure the patient is within the desired therapeutic range and to prevent adverse events related to over or under-anticoagulation. It is essential to monitor these values closely to adjust the dosage if needed. Notifying the healthcare provider of any concerning findings is important, but it may not be the immediate priority after receiving the third dose. Providing a PRN NSAID for gum discomfort is not typically indicated with oral anticoagulant therapy, as it may increase the risk of bleeding. Completing a medication variance report is more relevant in cases of medication errors or discrepancies, which may not apply in this scenario.
4. A client with chronic obstructive pulmonary disease (COPD) is prescribed ipratropium. The nurse should assess the client for which potential side effect?
- A. Nausea
- B. Dry mouth
- C. Cough
- D. Palpitations
Correct answer: B
Rationale: The correct answer is B: Dry mouth. Ipratropium can cause dry mouth as a common side effect due to its anticholinergic effects. Anticholinergic medications like ipratropium can lead to decreased salivary flow, resulting in dry mouth. Choices A, C, and D are incorrect because nausea, cough, and palpitations are not commonly associated with ipratropium use.
5. What should be obtained prior to starting olanzapine for a male client with bipolar disorder?
- A. Complete blood count
- B. Family history of hypertension
- C. History of erectile dysfunction
- D. Baseline weight
Correct answer: D
Rationale: Baseline weight should be obtained prior to starting olanzapine in a male client with bipolar disorder to monitor for potential weight gain associated with the medication. Olanzapine is known to cause weight gain and monitoring the baseline weight can help in assessing any changes during treatment.
