1. A client with multiple sclerosis starts a new prescription, baclofen, to control muscle spasticity. Three days later, the client calls the clinic nurse and reports feeling fatigued and dizzy. Which instruction should the nurse provide?
- A. Avoid hazardous activities until symptoms subside
- B. Contact the healthcare provider immediately
- C. Continue taking the medication every day
- D. Stop taking the medication until the unpleasant side effects wear off
Correct answer: A
Rationale: The correct instruction for the nurse to provide is to advise the client to avoid hazardous activities until the symptoms of fatigue and dizziness subside. These side effects can impair the client's ability to engage in activities that require alertness and coordination, posing a risk for accidents. Contacting the healthcare provider immediately may not be necessary unless the symptoms worsen or persist. Continuing to take the medication every day without addressing the side effects can lead to further complications. Stopping the medication abruptly without healthcare provider guidance can also be risky and may not be necessary if the symptoms improve with time.
2. A client with a history of deep vein thrombosis is prescribed warfarin. 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: The correct answer is A: Increased risk of bleeding. Warfarin is an anticoagulant medication that works by prolonging the time it takes for blood to clot. Therefore, a potential adverse effect of warfarin is an increased risk of bleeding. It is crucial for the nurse to monitor the client for signs of bleeding, such as easy bruising, prolonged bleeding from cuts, nosebleeds, or blood in the urine or stool. Monitoring for these signs is essential to prevent serious complications associated with excessive bleeding. Choices B, C, and D are incorrect because warfarin does not decrease the risk of bleeding, increase the risk of infection, or decrease the risk of infection. The primary concern with warfarin therapy is the potential for bleeding complications, so close monitoring for signs of bleeding is essential.
3. The healthcare professional is creating a class for older adults in the community. Which information about laxative use in older adults would be important to include?
- A. Laxatives are not effective in older adults
- B. All laxatives are exactly the same
- C. Over-the-counter laxatives are misused
- D. Laxatives can cause potassium retention
Correct answer: C
Rationale: It is important to include information about the misuse of over-the-counter laxatives in older adults as they often misuse these medications, which can lead to dependency and other health issues. Option A is incorrect as laxatives can be effective in older adults when used appropriately. Option B is incorrect because not all laxatives are the same, they have different mechanisms of action and side effects. Option D is incorrect because laxatives can actually cause electrolyte imbalances like potassium depletion rather than retention.
4. 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.
5. The client is receiving vancomycin, and the nurse plans to draw blood for a peak and trough to determine... the best timing for these levels?
- A. Midway through administration of the IV dose and 30 minutes before the next
- B. Two hours after completion of the IV dose and 30 minutes before the next
- C. Two hours after completion of the IV dose and one hour before the next
- D. Immediately after completion of the IV dose and 30 minutes before
Correct answer: B
Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations. Choice A is incorrect as drawing blood midway through administration does not provide an accurate peak level. Choice C is incorrect as drawing blood one hour before the next dose does not represent the trough level. Choice D is incorrect because drawing blood immediately after completion of the IV dose does not allow enough time for the drug to reach peak levels.
