1. A practical nurse (PN) is preparing to administer enoxaparin to a client. What is the most important action for the PN to take before administering this medication?
- A. Assess the client's blood pressure.
- B. Check the client's platelet count.
- C. Monitor the client's urine output.
- D. Review the client's blood glucose level.
Correct answer: B
Rationale: The correct answer is to check the client's platelet count. Enoxaparin can lead to thrombocytopenia (low platelet count), which can increase the risk of bleeding. Therefore, assessing the platelet count before administering enoxaparin is crucial to ensure that it is within a safe range. Assessing the client's blood pressure (Choice A) is not directly related to enoxaparin administration. Monitoring urine output (Choice C) and reviewing blood glucose levels (Choice D) are not essential actions before administering enoxaparin.
2. 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.
3. A client with amyotrophic lateral sclerosis (ALS) has been taking riluzole for two weeks. The nurse notes that the client remains weak with observable muscle atrophy. What action should the nurse take?
- A. Explain that the medication may take time to show improvement in symptoms
- B. Withhold the medication and notify the healthcare provider
- C. Advise the client to undergo liver function tests
- D. Document the assessment findings in the electronic health record
Correct answer: D
Rationale: In this scenario, the nurse's priority is to document the assessment findings in the electronic health record. This action is crucial for maintaining an accurate record of the client's health status and can provide valuable information for the healthcare team. While it is important to monitor the client's response to riluzole, explaining that the medication may take time to show improvement (Choice A) would be more appropriate if the client was expecting immediate results. Withholding the medication and notifying the healthcare provider (Choice B) should not be the initial action without further assessment or guidance. Advising the client to undergo liver function tests (Choice C) is not directly related to the current situation of weakness and muscle atrophy.
4. A client with a diagnosis of generalized anxiety disorder is prescribed sertraline. The nurse should instruct the client that this medication may have which potential side effect?
- A. Nausea
- B. Drowsiness
- C. Insomnia
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Nausea. Sertraline, a selective serotonin reuptake inhibitor (SSRI), is known to commonly cause gastrointestinal side effects such as nausea. It is recommended for clients to take sertraline with food to help minimize this potential side effect. Choice B, Drowsiness, is less commonly associated with sertraline use. Insomnia, choice C, is not a typical side effect of sertraline; in fact, it may help improve sleep in some individuals. Headache, choice D, is also not a common side effect of sertraline.
5. A client vomits 30 minutes after receiving a dose of hydromorphone on the first postoperative day. What initial intervention is best for the practical nurse (PN) to implement?
- A. Obtain a prescription for nasogastric intubation.
- B. Administer a prn dose of ondansetron.
- C. Reduce the next scheduled dose of hydromorphone.
- D. Assess the client's abdomen and bowel sounds.
Correct answer: B
Rationale: In this scenario, the client's vomiting is likely due to the hydromorphone administration, indicating a need for an antiemetic such as ondansetron to address the nausea. Nasogastric intubation (Choice A) is not necessary at this point as the client is vomiting, not experiencing an obstruction. While reducing the dose of hydromorphone (Choice C) may be considered later, the immediate focus should be managing the client's symptoms. Assessing the client's abdomen and bowel sounds (Choice D) can be important but is not the initial priority when addressing the vomiting post hydromorphone administration.
