1. A client with a prescription to take theophylline (Theo-24) daily has been given medication instructions by the nurse. The nurse determines that the client needs further information about the medication if the client states that he or she will:
- A. Drink at least 2 L of fluid per day.
- B. Take the daily dose at bedtime.
- C. Avoid changing brands of the medication without health care provider (HCP) approval.
- D. Avoid over-the-counter (OTC) cough and cold medications unless approved by the HCP.
Correct answer: B
Rationale: The correct answer is B. Taking theophylline at bedtime is inappropriate because it can cause insomnia. The medication should be taken early in the morning to avoid disrupting sleep patterns. It is important to follow the healthcare provider's instructions regarding the timing of the medication to achieve optimal therapeutic effects.
2. A client is taking ticlopidine hydrochloride (Ticlid). The nurse tells the client to avoid which of the following while taking this medication?
- A. Vitamin C
- B. Vitamin D
- C. Acetaminophen (Tylenol)
- D. Acetylsalicylic acid (aspirin)
Correct answer: D
Rationale: Ticlopidine hydrochloride is a platelet aggregation inhibitor. Aspirin or any aspirin-containing product should be avoided as they can precipitate or aggravate bleeding by affecting platelet function and increasing the risk of bleeding complications.
3. A client with chronic pain is prescribed transdermal fentanyl (Duragesic) patches. Which instruction should the nurse include in the teaching plan?
- A. Apply the patch to a different site each time.
- B. Avoid using heating pads over the patch.
- C. Change the patch every 72 hours.
- D. Remove the old patch before applying the new one.
Correct answer: B
Rationale: Clients using transdermal fentanyl (Duragesic) patches should avoid using heating pads over the patch as heat can increase the release of the medication, potentially leading to overdose. The patch should be applied to a different site each time, changed every 72 hours, and the old patch should be removed before applying a new one to prevent accidental overdose or excessive drug absorption.
4. Oral iron supplements are prescribed for a 6-year-old child with iron deficiency anemia. The nurse instructs the mother to administer the iron with which of the following food items?
- A. Milk
- B. Water
- C. Apple juice
- D. Orange juice
Correct answer: D
Rationale: Iron absorption is enhanced by the presence of vitamin C. Orange juice is a good source of vitamin C, which can improve the absorption of iron when taken together. Therefore, administering iron supplements with orange juice is the best choice to optimize iron absorption for the child.
5. Why is prostaglandin E1 prescribed for a child with transposition of the great arteries?
- A. Prevents hypercyanotic (blue or tet) spells
- B. Maintains an adequate hormone level
- C. Maintains the position of the great arteries
- D. Provides adequate oxygen saturation and maintains cardiac output
Correct answer: D
Rationale: Prostaglandin E1 is prescribed for a child with transposition of the great arteries to increase blood mixing, which helps maintain adequate oxygen saturation and cardiac output. This medication does not prevent hypercyanotic spells, maintain hormone levels, or influence the position of the great arteries.
