Question 1 of 5
The client calls a clinic 2 weeks after taking oral carbidopa-levodopa, stating that the medication has been ineffective in controlling the symptoms of PD. What nursing action is most important?
Correct Answer: C
Rationale: A: Reviewing the method for taking carbidopa-levodopa, including foods to avoid, may be important, but option C is most important. More information is needed to determine whether the client is taking it correctly. B: A dosage change is unnecessary because it has been only two weeks since the client started carbidopa-levodopa. C: With oral administration of carbidopa-levodopa (Sinemet), it usually takes 1 to 2 months before an effect is noted, although in some cases it may require up to 6 months. D: A high-protein diet can slow or prevent absorption of carbidopa-levodopa. Vitamin B6 increases the action of decarboxylases that destroy levodopa in the body's periphery, reducing the effects of carbidopa-levodopa. Foods high in pyridoxine should be avoided.
Question 2 of 5
You are caring for a 78-year-old woman who is wondering why she was diagnosed with glaucoma. Although she has several risk factors, which of these is not one of them?
Correct Answer: D
Rationale: Age over 60 and Mexican-American ancestry are both risk factors for glaucoma. Elevated blood pressure also is a risk factor as it can cause optic nerve damage. 20/80 vision, while poor, is not a causal factor for glaucoma.
Question 3 of 5
In teaching bleeding precautions to a client with leukemia, the PN should include which of the following instructions?
Correct Answer: A
Rationale: A soft toothbrush minimizes gum bleeding in leukemia clients with low platelets. Dental floss and razors increase bleeding risk, and pressure should be held for 5-10 minutes.
Question 4 of 5
The client's dose of mirtazapine was increased from 15 to 30 mg at bedtime two days ago. When the nurse is preparing to administer mirtazapine, the client reports having insomnia, irritability, and panic attacks. What should the nurse do next?
Correct Answer: A
Rationale: Mirtazapine (Remeron) is an antidepressant. Adverse effects include insomnia, irritability, panic attacks, and suicidal ideation. A change in medication may be needed rather than a dosage increase.
