1. A client with chronic obstructive pulmonary disease (COPD) is prescribed tiotropium (Spiriva). Which instruction should the nurse include in the teaching plan?
- A. Use the medication as a rescue inhaler.
- B. Rinse your mouth after using the inhaler.
- C. Take the medication on an empty stomach.
- D. Take the medication with a full glass of water.
Correct answer: B
Rationale: Tiotropium (Spiriva) is not a rescue inhaler but a maintenance medication for COPD. The correct instruction for the nurse to include in the teaching plan is to advise the client to rinse their mouth after using the inhaler. This practice helps prevent dry mouth and throat irritation, common side effects of tiotropium. There are no specific recommendations to take tiotropium on an empty stomach or with a full glass of water.
2. Mycophenolate mofetil (CellCept) is prescribed for a client as prophylaxis for organ rejection following an allogeneic renal transplant. Which of the following instructions does the nurse reinforce regarding administration of this medication?
- A. Administer on an empty stomach.
- B. Take the medication with a calcium-type antacid.
- C. Open the capsule and mix with food for administration.
- D. Contact the health care provider (HCP) if a sore throat occurs.
Correct answer: D
Rationale: The correct instruction for administering mycophenolate mofetil (CellCept) is to contact the healthcare provider (HCP) if unusual bleeding or bruising, sore throat, or other adverse effects occur. It is essential not to open or crush the capsules to maintain the medication's efficacy.
3. Phenazopyridine hydrochloride (Pyridium) is prescribed for a client for symptomatic relief of pain resulting from a lower urinary tract infection. The nurse reinforces to the client:
- A. To take the medication after meals
- B. To take the medication before meals
- C. To discontinue the medication if a headache occurs
- D. That a reddish-orange discoloration of the urine may occur
Correct answer: D
Rationale: The nurse should instruct the client that a reddish-orange discoloration of urine may occur. The nurse should also educate the client that this discoloration can stain fabric. It is recommended to take the medication after meals to reduce the possibility of gastrointestinal upset. While a headache is an occasional side effect of the medication, it does not warrant discontinuation of the medication.
4. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the client's teaching plan?
- A. Avoid taking folic acid supplements.
- B. Report any signs of infection immediately.
- C. Take the medication with a full meal.
- D. Limit fluid intake while on this medication.
Correct answer: B
Rationale: The correct instruction for the nurse to include in the client's teaching plan when taking methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the client more susceptible to infections. It is important for the client to promptly report any signs of infection to receive timely medical intervention. Choice A is incorrect because folic acid supplements are often recommended to reduce side effects of methotrexate. Choice C is incorrect as methotrexate is usually taken on an empty stomach unless the client experiences gastrointestinal upset. Choice D is incorrect as there is no need to limit fluid intake while on methotrexate; in fact, maintaining adequate fluid intake is important to prevent complications such as kidney damage.
5. The healthcare provider prescribes exenatide (Byetta) for a client with type 1 diabetes mellitus who takes insulin. What is the appropriate intervention for the nurse?
- A. Administer the medication within 60 minutes before the morning and evening meal.
- B. Withhold the medication and question the prescription with the healthcare provider.
- C. Monitor the client for gastrointestinal side effects after administration of the medication.
- D. Withdraw the insulin from the Penlet into an insulin syringe to prepare for administration.
Correct answer: B
Rationale: Exenatide (Byetta) is specifically indicated for the treatment of type 2 diabetes mellitus and is not recommended for clients with type 1 diabetes mellitus who are taking insulin. Choice A is incorrect because exenatide should not be administered to a client with type 1 diabetes mellitus who takes insulin. Choice C is not the most appropriate initial action when the prescription is not suitable for the client. Choice D is unrelated to the administration of exenatide. Therefore, the appropriate intervention for the nurse is to withhold the medication and question the prescription with the healthcare provider to ensure the safety and appropriateness of the treatment plan for the client.
