1. 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.
2. When is the best time for a client to take a daily dose of prednisone?
- A. At noon
- B. At bedtime
- C. Early morning
- D. Anytime, at the same time each day
Correct answer: C
Rationale: The correct time for a client to take a daily dose of prednisone is early morning. Corticosteroids like prednisone should be taken in the morning to mimic the body's natural hormone release pattern. This timing helps reduce the risk of disrupting the body's internal clock and minimizes the potential for insomnia or other sleep disturbances.
3. A healthcare professional is preparing to administer digoxin (Lanoxin), 0.125 mg orally, to a client with heart failure. Which vital sign is most important for the healthcare professional to check before administering the medication?
- A. Heart rate
- B. Temperature
- C. Respirations
- D. Blood pressure
Correct answer: A
Rationale: Before administering digoxin, it is essential to assess the client's heart rate as this medication directly affects cardiac function. Monitoring the heart rate helps identify if it is within the acceptable range for administering digoxin. A pulse rate below 60 beats per minute warrants withholding the medication to prevent potential adverse effects like bradycardia or cardiac arrhythmias.
4. 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.
5. A healthcare professional prepares to administer sodium polystyrene sulfonate (Kayexalate) to a client. Before administering the medication, the professional reviews the action of the medication and understands that it:
- A. Releases bicarbonate in exchange for primarily sodium ions
- B. Releases sodium ions in exchange for primarily potassium ions
- C. Releases potassium ions in exchange for primarily sodium ions
- D. Releases sodium ions in exchange for primarily bicarbonate ions
Correct answer: B
Rationale: Sodium polystyrene sulfonate, such as Kayexalate, is a cation exchange resin that functions by releasing sodium ions in exchange for primarily potassium ions. This medication is commonly used to treat hyperkalemia, a condition characterized by elevated levels of potassium in the blood.
