The physician writes an order for ziprasidone hydrochloride (Geodon) 80 mg. Each tablet contains 20 mg. How many tablets would you administer?

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.

A. A respiratory rate of 14

A respiratory rate of 14 is within the normal range and is not typically a reason to hold benztropine. Respiratory depression is not a common side effect of this medication.

B. A pulse of 102

A pulse rate of 102 is also within the normal range, and changes in heart rate are generally not a prominent side effect of benztropine. This finding alone is not a typical reason to hold the medication.

C. Blood pressure of 88/60 mmHg

This is the correct choice. Anticholinergic medications, like benztropine, can cause side effects such as a decrease in blood pressure. A blood pressure of 88/60 mmHg may be a concern, and the nurse should hold the dose and notify the physician.

D. A temperature of 100.2°F

An elevated temperature of 100.2°F is not a direct contraindication to benztropine administration. Fever is not a typical side effect of this medication, so an increased temperature alone is not a reason to hold the dose.
