1. A client with a history of deep vein thrombosis is prescribed enoxaparin. The nurse should monitor for which potential adverse effect?
- A. Increased risk of bleeding
- B. Decreased risk of bleeding
- C. Increased risk of infection
- D. Decreased risk of infection
Correct answer: A
Rationale: Enoxaparin is an anticoagulant that works by preventing blood clots. One of the potential adverse effects of enoxaparin is an increased risk of bleeding due to its anticoagulant properties. Therefore, the nurse should monitor the client for signs of bleeding, such as easy bruising, petechiae, or blood in stool or urine, to ensure timely intervention and prevent complications.
2. Which action should be taken to assess for analgesic tolerance in a client who is unable to communicate?
- A. Review the client's laboratory values for changes in peak and trough levels of the analgesic
- B. Prolong the interval between analgesic medication doses and monitor the client's vital signs
- C. Observe the client for the presence of pain behaviors before the next analgesic dose is due
- D. Ask family members to report behaviors suggesting that the client's pain has returned
Correct answer: C
Rationale: In clients who are unable to communicate, observing for pain behaviors is crucial in assessing analgesic tolerance. Changes in pain behaviors can indicate if the current analgesic regimen is effective or if tolerance has developed. Therefore, closely observing the client for pain behaviors before the next analgesic dose helps healthcare providers evaluate the client's response to pain management. Reviewing laboratory values may not directly reflect analgesic tolerance. Prolonging the interval between doses and monitoring vital signs may not provide direct information on analgesic tolerance. Relying solely on family members to report pain behaviors may not be as accurate or immediate as observing the client directly.
3. When a client with hypertension is prescribed losartan, what potential side effect should the nurse monitor for?
- A. Hyperkalemia
- B. Dry cough
- C. Bradycardia
- D. Headache
Correct answer: B
Rationale: The correct answer is B: Dry cough. Losartan, an angiotensin II receptor blocker, can lead to a dry cough as a potential side effect. This occurs due to the drug's effect on the bradykinin pathway in the lungs. Monitoring for a dry cough is essential as it may indicate the need for further evaluation or medication adjustment to manage this adverse reaction.
4. A client with gastroesophageal reflux disease (GERD) is prescribed omeprazole. The nurse should reinforce which instruction?
- A. Take this medication in the morning before breakfast.
- B. Take this medication with meals.
- C. Avoid taking this medication with antacids.
- D. Take this medication at bedtime.
Correct answer: A
Rationale: The correct instruction for a client with GERD prescribed omeprazole is to take the medication in the morning before breakfast. Omeprazole works best when taken on an empty stomach, approximately 30 minutes before the first meal of the day. This timing maximizes its effectiveness in reducing stomach acid production and helps manage symptoms of GERD more efficiently. Choice B is incorrect because taking omeprazole with meals may reduce its efficacy as it needs an empty stomach for optimal absorption. Choice C is incorrect because omeprazole can be taken with or without food, but it should not be taken with antacids as they can affect its absorption. Choice D is incorrect because taking omeprazole at bedtime is less effective compared to taking it before breakfast due to the circadian rhythm of gastric acid secretion.
5. A client is prescribed phenobarbital 100 mg daily for the treatment of seizures. Which statement made by the client indicates an accurate understanding of the medication phenobarbital?
- A. I will take my medicine at 10 PM before retiring to bed.
- B. The medication will turn the color of my urine to a pink color.
- C. I should not eat or drink anything for at least 2 hours before taking my medicine.
- D. In the event a seizure occurs in the middle of the day, I need to take an extra dose of my medicine.
Correct answer: A
Rationale: The correct answer is A. Phenobarbital should be taken at the same time every day to maintain blood levels and enhance compliance. Common side effects of phenobarbital include drowsiness, lethargy, dizziness, and nausea; therefore, it is best to take it before bedtime to minimize these effects and improve sleep quality. Choice B is incorrect because phenobarbital does not affect the color of urine. Choice C is incorrect because there is no need to fast before taking phenobarbital. Choice D is incorrect because taking extra doses without healthcare provider guidance can lead to overdose and adverse effects.
