1. A client with tuberculosis (TB) is taking isoniazid (INH). Which instruction is most important for the nurse to include?
- A. Take the medication with food to avoid stomach upset.
- B. Avoid exposure to sunlight while taking this medication.
- C. Report any numbness or tingling in extremities.
- D. Have liver function tests done regularly.
Correct answer: D
Rationale: Regular monitoring of liver function tests is crucial for clients taking isoniazid (INH) due to the potential risk of hepatotoxicity. Isoniazid can cause liver damage, and early detection through routine liver function tests can help prevent severe complications.
2. A client is on intravenous heparin to treat a pulmonary embolism. The client's most recent partial thromboplastin time (PTT) was 25 seconds. What action should the nurse anticipate?
- A. Decrease the heparin rate.
- B. Increase the heparin rate.
- C. No change to the heparin rate.
- D. Stop the heparin; start warfarin (Coumadin).
Correct answer: B
Rationale: For clients on heparin therapy, a PTT value of 1.5 to 2.5 times the normal range is required to ensure therapeutic anticoagulation. The normal PTT range is 25 to 35 seconds. In this case, the client's PTT of 25 seconds falls below the therapeutic range, indicating that the heparin dose is insufficient. Therefore, the nurse should anticipate increasing the heparin rate to achieve the desired therapeutic effect.
3. A nurse assesses a client who has a history of heart failure. Which question should the nurse ask to assess the extent of the client's heart failure?
- A. Do you have trouble breathing or chest pain?
- B. Are you able to walk upstairs without fatigue?
- C. Do you awake with breathlessness during the night?
- D. Do you have new-onset heaviness in your legs?
Correct answer: B
Rationale: Clients with a history of heart failure generally have negative findings, such as shortness of breath. The nurse needs to determine whether the client's activity is the same or worse, or whether the client identifies a decrease in activity level. Trouble breathing, chest pain, breathlessness at night & peripheral edema are symptoms of heart failure, but do not provide data that can determine the extent of the client's heart failure.
4. A client with hypertension is being taught about lifestyle modifications. Which statement by the client indicates a need for further teaching?
- A. I will reduce my sodium intake to help control my blood pressure.
- B. I need to start walking at least 30 minutes most days of the week.
- C. I can continue drinking alcohol as long as it is not in excess.
- D. I will check my blood pressure regularly at home.
Correct answer: C
Rationale: In hypertension management, it is crucial for clients to limit or avoid alcohol consumption, not just refrain from excess. Alcohol can raise blood pressure and interfere with the effectiveness of antihypertensive medications, making it a key lifestyle modification for individuals with hypertension.
5. A student learns about modifiable risk factors for coronary artery disease. Which factors does this include? (Select one that does not apply)
- A. Age
- B. Hypertension
- C. Obesity
- D. Smoking
Correct answer: A
Rationale: Hypertension, obesity, smoking, and excessive stress are all modifiable risk factors for coronary artery disease, as they can be changed or controlled through interventions. Age, on the other hand, is a nonmodifiable risk factor, meaning it cannot be altered. Understanding the difference between modifiable and nonmodifiable risk factors is essential in preventive healthcare strategies.
