The nurse is teaching a patient who has Parkinson's disease about the side effects of carbidopa-levodopa. Which statement by the patient indicates a need for further teaching?

"I may experience urinary retention, dry mouth, and constipation."

"I may feel dizzy at first, but this side effect will go away with time."

"I should report nightmares and mental disturbances to my provider."

"I should take the drug with food to increase absorption."

Answer and Explanation

The Correct Answer is D

A. "I may experience urinary retention, dry mouth, and constipation."

This statement is accurate. Urinary retention, dry mouth, and constipation are common side effects of carbidopa-levodopa. The patient should be aware of these potential side effects and report them to the healthcare provider if they become problematic.

B. "I may feel dizzy at first, but this side effect will go away with time."

This statement is accurate. Dizziness is a common initial side effect of carbidopa-levodopa, and it often improves with continued use. The patient should be encouraged to report persistent dizziness to the healthcare provider.

C. "I should report nightmares and mental disturbances to my provider."

This statement is accurate. Nightmares and mental disturbances can be side effects of carbidopa-levodopa. The patient should report these symptoms to the healthcare provider for further evaluation and potential adjustments to the medication.

D. "I should take the drug with food to increase absorption."

This statement indicates a need for further teaching. Carbidopa-levodopa is best absorbed when taken on an empty stomach. Taking it with food, especially high-protein meals, can reduce its absorption. The patient should be instructed to take the medication at least 30 minutes before meals or one to two hours after meals for optimal effectiveness.

Correct Answer is A

Explanation

A. Aspirin and warfarin

The combination of aspirin and warfarin poses a potential risk of increased bleeding and bruising. Both aspirin and warfarin are anticoagulants, and when used together, they can potentiate each other's effects, leading to a higher risk of bleeding events, including easy bruising.

B. Sulfasalazine and acetaminophen

Sulfasalazine is often used in the treatment of arthritis and inflammatory bowel disease, while acetaminophen is a commonly used pain reliever. There is no significant interaction between these two medications leading to increased bleeding or bruising.

C. Tolmetin and propranolol

Tolmetin is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief, and propranolol is a beta-blocker used for conditions such as hypertension. While both medications have their own potential side effects, there is no specific interaction between them that significantly increases the risk of bleeding or bruising.

D. Meloxicam and amlodipine

Meloxicam is an NSAID, and amlodipine is a calcium channel blocker used for hypertension. Similar to option C, there is no known significant interaction between these two medications that would lead to increased bleeding or bruising.

Correct Answer is ["3"]

Explanation

To calculate the dosage of furosemide (Lasix), a diuretic medication, you need to divide the ordered amount by the tablet strength.

In this case, the ordered amount is 120 mg and the tablet strength is 40 mg.

Therefore, you need to divide 120 by 40, which gives you 3.

This means you would administer 3 tablets of furosemide (Lasix) to the patient.
