Question 1 of 5
The nurse is caring for a client with a medical prescription for clozapine [Clozaril]. The nurse knows which of the following is the priority laboratory value that should be reviewed prior to medication administration?
Correct Answer: A
Rationale: The correct answer is A: White blood cell count. Prior to administering clozapine, it is crucial to review the white blood cell count due to the risk of agranulocytosis, a potentially life-threatening side effect. A low white blood cell count can indicate a higher risk of developing agranulocytosis, which requires immediate medical intervention. Monitoring the white blood cell count is essential for detecting this adverse effect early on.
B: Potassium level is not the priority value before administering clozapine. While monitoring potassium levels is important, it is not directly related to the potential adverse effects of clozapine.
C: BUN/Creatinine levels are important for monitoring kidney function but are not the priority values before administering clozapine.
D: Sodium level is not the priority value before administering clozapine. While monitoring sodium levels is important, it is not directly related to the potential adverse effects of clozapine.
Question 2 of 5
A client has been prescribed zolpidem (Ambien) for insomnia. The client's spouse reports that the patient drives at night but does not remember it in the morning. Which of the following explains this behavior?
Correct Answer: B
Rationale:
Correct
Answer: B - This is a complex sleep behavior with memory loss associated with this drug.
Rationale:
1. Zolpidem is a sedative-hypnotic medication used for insomnia.
2. Complex sleep behaviors, such as sleep-driving, have been reported with zolpidem.
3. Memory loss or amnesia for events during drug use is a known side effect.
4. The client's behavior of driving at night without memory in the morning aligns with the known effects of zolpidem.
Summary:
A: Incorrect - Side effect does not resolve after 2 weeks.
C: Incorrect - Not indicative of a severe allergic reaction.
D: Incorrect -
Toxic levels typically present with different symptoms.
Overall, choice B best explains the behavior observed in the client.
Question 3 of 5
The nurse is evaluating the therapeutic effects of nitroglycerin transdermal patches prescribed to a client 6 months ago. Which of the following statements by the client would indicate that the medication is effective?
Correct Answer: C
Rationale: The correct answer is C. The statement "I am tolerating exercise without pain on a regular basis" indicates that the nitroglycerin transdermal patches are effective in managing angina. Nitroglycerin works by dilating blood vessels to increase oxygen supply to the heart, allowing the client to exercise without experiencing chest pain. Options A, B, and D are incorrect because they do not directly relate to the therapeutic effects of nitroglycerin in managing angina symptoms. Blood pressure improvement, absence of anginal attacks, and reduction in headaches could be related to other factors and do not specifically indicate the effectiveness of nitroglycerin in managing angina.
Question 4 of 5
The client has been taking a medical prescription of ferrous sulfate [Feosol] for 30 days. During a follow-up assessment, the nurse will observe for which therapeutic response?
Correct Answer: A
Rationale: The correct answer is A: Increased activity tolerance. Ferrous sulfate is an iron supplement used to treat anemia, which leads to symptoms like fatigue and weakness. By increasing the client's iron levels, it can improve oxygen transport and energy production, resulting in increased activity tolerance. Monitoring for this therapeutic response is crucial to assess the effectiveness of the medication.
Choices B, C, and D are incorrect as ferrous sulfate does not directly affect blood glucose levels, low-density lipoprotein, or urinary output.
Question 5 of 5
The nurse is preparing discharge instructions for a patient taking warfarin (Coumadin). Which would the nurse correctly include in the discharge instructions?
Correct Answer: B,C,D
Rationale:
Correct
Answer: B, C, D
Rationale:
B: Carrying an emergency ID is crucial as it alerts healthcare providers about warfarin use in case of emergencies.
C: Avoiding hazardous activities reduces the risk of bleeding, a common side effect of warfarin.
D: Regular follow-up and lab work are essential to monitor warfarin's effectiveness and prevent complications.
Incorrect
Choices:
A: Eating large salads can affect warfarin's effectiveness due to vitamin K content.
E: Alcohol can interact with warfarin, increasing the risk of bleeding.
Summary: The correct choices focus on safety and monitoring while the incorrect choices pose risks of interactions and complications.
