1. 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.
2. A nurse reinforces discharge instructions to a postoperative client who is taking warfarin sodium (Coumadin). Which statement, if made by the client, reflects the need for further teaching?
- A. I will take my pills every day at the same time.
- B. I will be certain to avoid alcohol consumption.
- C. I have already called my family to pick up a Medic-Alert bracelet.
- D. I will take Ecotrin (enteric-coated aspirin) for my headaches because it is coated.
Correct answer: D
Rationale: Ecotrin is an aspirin-containing product and should be avoided. Clients should avoid alcohol consumption, take prescribed medication at the same time each day, and use a Medic-Alert bracelet for emergency information.
3. A client is receiving meperidine (Demerol) for pain management. Which assessment finding requires immediate action?
- A. Constipation
- B. Drowsiness
- C. Respiratory rate of 10 breaths per minute
- D. Nausea
Correct answer: C
Rationale: A respiratory rate of 10 breaths per minute indicates respiratory depression, a severe side effect of meperidine (Demerol) that necessitates immediate intervention to prevent further complications. Constipation, drowsiness, and nausea are common but less urgent side effects that do not pose an immediate life-threatening risk. Respiratory depression can lead to respiratory arrest and must be addressed promptly to ensure the client's safety and well-being.
4. A child is hospitalized with a diagnosis of lead poisoning. The healthcare provider assisting in caring for the child would prepare to assist in administering which of the following medications?
- A. Activated charcoal
- B. Sodium bicarbonate
- C. Syrup of ipecac
- D. Dimercaprol (BAL in Oil)
Correct answer: D
Rationale: Dimercaprol (BAL in Oil) is a chelating agent indicated for lead poisoning. It works by binding to lead and facilitating its removal from the body. Activated charcoal is used for certain types of poisoning by adsorbing toxins, while sodium bicarbonate can be used to treat acidosis. Syrup of ipecac is no longer recommended for poison treatment due to potential risks.
5. A client taking fexofenadine (Allegra) is scheduled for allergy skin testing and tells the nurse in the healthcare provider's office that a dose was taken this morning. The nurse determines that:
- A. The client should reschedule the appointment.
- B. A lower dose of allergen will need to be injected.
- C. A higher dose of allergen will need to be injected.
- D. The client should have the skin test read a day later than usual.
Correct answer: A
Rationale: Fexofenadine, an antihistamine, can cause false-negative readings in allergy skin testing and should be discontinued 3 days prior. Therefore, the client should reschedule the appointment to ensure accurate test results.
