1. A client is being taught about the use of nitroglycerin (Nitrostat) for angina. Which statement by the client indicates a need for further teaching?
- A. I will sit or lie down when I take the medication.
- B. I can take up to three tablets, 5 minutes apart, if needed.
- C. I will call 911 if my chest pain is not relieved after taking three tablets.
- D. I will keep the medication in its original dark container.
Correct answer: B
Rationale: The correct administration of nitroglycerin for angina is to take up to three tablets, 5 minutes apart. If the chest pain persists after the third tablet, emergency medical services should be called. Taking more than three tablets or reducing the time interval between doses may lead to hypotension and indicates a need for further teaching.
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 client with heart failure is prescribed furosemide (Lasix) and digoxin (Lanoxin). Which instruction should the nurse include in the client's teaching plan?
- A. Avoid foods high in potassium.
- B. Report a pulse rate less than 60 beats per minute.
- C. Take the medications in the morning.
- D. Weigh yourself daily.
Correct answer: B
Rationale: The correct answer is B. The nurse should instruct the client to report a pulse rate less than 60 beats per minute, as it could indicate digoxin toxicity. Consuming potassium-rich foods is encouraged due to the potential for furosemide (Lasix) to cause hypokalemia. The medications should be taken in the morning to prevent nocturia. Weighing oneself daily is important to monitor for fluid retention, a crucial aspect in managing heart failure. Therefore, choices A, C, and D are incorrect as they do not address the specific teaching point related to digoxin and its potential toxicity.
4. 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.
5. Tamoxifen is prescribed for the client with metastatic breast carcinoma. The nurse understands that the primary action of this medication is to:
- A. Increase DNA and RNA synthesis.
- B. Promote the biosynthesis of nucleic acids.
- C. Increase estrogen concentration and estrogen response.
- D. Compete with estradiol for binding to estrogen in tissues containing high concentrations of receptors.
Correct answer: D
Rationale: The primary action of tamoxifen, an antineoplastic medication used in metastatic breast carcinoma, is to compete with estradiol for binding to estrogen receptors in tissues with high receptor concentrations. By doing so, tamoxifen reduces DNA synthesis and estrogen response, leading to its therapeutic effect in inhibiting the growth of estrogen-sensitive breast cancer cells.
