A patient with a complicated medical history including hypertension, a-fib, and arthritis calls the health care provider's office to speak with a nurse about "all of these bruises I have all of a sudden." Which potential drug interaction should concern the nurse with these symptoms?

Aspirin and warfarin

Sulfasalazine and acetaminophen

Tolmetin and propranolol

Meloxicam and amlodipine

Answer and Explanation

The Correct Answer is A

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 A

Explanation

A. Headache, dizziness, and fatigue

Ondansetron (Zofran) is commonly used to control nausea and vomiting associated with chemotherapy. While it is generally well-tolerated, some common side effects may include headache, dizziness, and fatigue.

B. Anorexia and hair loss

Anorexia (loss of appetite) and hair loss are not commonly associated with ondansetron. These symptoms may be side effects of chemotherapy itself, but they are not typically attributed to ondansetron.

C. Abdominal cramping and irritability

Abdominal cramping and irritability are not common side effects of ondansetron. These symptoms may be related to other factors, but they are not typically associated with this antiemetic medication.

D. Psychosis and middle ear disturbances

Psychosis and middle ear disturbances are not common side effects of ondansetron. These symptoms may be associated with other medications or conditions, but they are not typically attributed to ondansetron.

Correct Answer is ["36"]

Explanation

To calculate the infusion time for an IV of 1,500 mL running at 25 gtt/min. if the drop factor is 15 gtt/mL, we need to use the following formula:

Infusion time (in minutes) = Volume (in mL) x Drop factor (in gtt/mL) / Flow rate (in gtt/min)

Plugging in the given values, we get:

Infusion time = 1,500 x 15 / 25

Infusion time = 900 / 25

Infusion time = 36

Therefore, the infusion time for this IV is 36 minutes.
