1. 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.
2. A client with diabetes mellitus type 2 is prescribed canagliflozin. The nurse should include which instruction in the client's teaching plan?
- A. Report any signs of urinary tract infection.
- B. Take this medication with meals.
- C. Avoid alcohol while taking this medication.
- D. Avoid taking this medication with grapefruit juice.
Correct answer: A
Rationale: The correct instruction to include in the client's teaching plan is to report any signs of urinary tract infection. Canagliflozin, a medication used in diabetes mellitus type 2, can increase the risk of urinary tract infections. Instructing the client to report any signs of infection is crucial for early intervention and management. Choices B, C, and D are incorrect because there is no specific requirement to take canagliflozin with meals, avoid alcohol, or restrict grapefruit juice consumption while on this medication.
3. A client who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. While taking the client's history, the nurse determines the client has been self-administering St. John's wort, an herbal preparation, on the advice of a friend. What information is most significant about this finding?
- A. Wort can decrease plasma concentration of Cyclospora
- B. Wort can decrease plasma concentration of Tacrolimus
- C. Wort can decrease plasma concentration of Cyclosporine
- D. Wort can decrease plasma concentration of Mycophenolate
Correct answer: C
Rationale: The most significant information about the client self-administering St. John's wort, an herbal preparation, is that it can decrease the plasma concentration of Cyclosporine. St. John's wort is known to reduce the efficacy of Cyclosporine, which is a common immunosuppressant drug used to prevent transplant rejection. Choices A, B, and D are incorrect because St. John's wort does not affect the plasma concentration of Cyclospora, Tacrolimus, or Mycophenolate.
4. 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.
5. A client is prescribed methylprednisolone for an allergic reaction. The nurse should monitor for which potential side effect of this medication?
- A. Nausea and vomiting
- B. Weight gain
- C. Insomnia
- D. Increased appetite
Correct answer: B
Rationale: When a client is prescribed methylprednisolone, a corticosteroid, the nurse should monitor for weight gain as a potential side effect. Corticosteroids like methylprednisolone can cause weight gain and fluid retention due to their impact on metabolism and sodium retention. Nausea and vomiting are less common side effects of methylprednisolone. Insomnia and increased appetite are not typically associated with methylprednisolone use.
