1. A client diagnosed with multiple sclerosis self-administers beta-1 interferon subcutaneously
- A. Explain to the client that the medication dose may need to be increased
 - B. Instruct the client to withhold the drug until the next exacerbation
 - C. Advise the client to consult the healthcare provider as soon as possible
 - D. Encourage the client to continue taking the medication
 
Correct answer: D
Rationale: Encouraging the client to continue taking the medication is crucial in the management of multiple sclerosis. Beta-1 interferon is a disease-modifying drug used to reduce the frequency and severity of relapses in multiple sclerosis. Discontinuing the medication without medical advice can lead to disease exacerbation. It is essential for the client to maintain regular dosing to achieve optimal therapeutic effects and disease control.
2. What should be obtained prior to starting olanzapine for a male client with bipolar disorder?
- A. Complete blood count
 - B. Family history of hypertension
 - C. History of erectile dysfunction
 - D. Baseline weight
 
Correct answer: D
Rationale: Baseline weight should be obtained prior to starting olanzapine in a male client with bipolar disorder to monitor for potential weight gain associated with the medication. Olanzapine is known to cause weight gain and monitoring the baseline weight can help in assessing any changes during treatment.
3. A client with a diagnosis of schizophrenia is prescribed aripiprazole. The nurse should monitor the client for which potential side effect?
- A. Weight gain
 - B. Dry mouth
 - C. Headache
 - D. Increased appetite
 
Correct answer: A
Rationale: Aripiprazole is known to cause weight gain in patients, so monitoring for changes in weight is essential to assess for this potential side effect and intervene accordingly.
4. A client with a history of atrial fibrillation is prescribed warfarin. The nurse should monitor for which sign of potential bleeding?
- A. Elevated blood pressure
 - B. Bruising
 - C. Shortness of breath
 - D. Nausea and vomiting
 
Correct answer: B
Rationale: Warfarin is an anticoagulant that increases the risk of bleeding. Bruising is a common sign of potential bleeding in clients taking warfarin. Monitoring for bruising is essential as it can indicate a risk of bleeding that needs further assessment and management. Elevated blood pressure, shortness of breath, nausea, and vomiting are not direct signs of potential bleeding associated with warfarin therapy.
5. A client with a diagnosis of generalized anxiety disorder is prescribed hydroxyzine. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
 - B. Dry mouth
 - C. Nausea
 - D. Headache
 
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Hydroxyzine is known to cause drowsiness, so clients should be advised to avoid activities like driving until they understand how the medication affects them. Choices B, C, and D are incorrect because dry mouth, nausea, and headache are not commonly associated with hydroxyzine use. It is crucial for the client to be aware of the potential drowsiness to ensure their safety and well-being while taking this medication.
