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.

A. Blood dyscrasias B. Hyperglycemia C. Urinary retention D. Gingival hyperplasia E. Sedation

Correct Answer is ["A","D"]

Explanation

A. Blood dyscrasias: This is a correct choice. Phenytoin can cause blood dyscrasias, including conditions like leukopenia, thrombocytopenia, and anemia.

B. Hyperglycemia: This is not typically associated with phenytoin. The primary adverse effects related to blood sugar are usually changes in glucose metabolism or hypoglycemia.

C. Urinary retention: This is not a common adverse effect of phenytoin. It is more associated with other medications or medical conditions.

D. Gingival hyperplasia: This is a correct choice. Phenytoin is known to cause gingival hyperplasia, which is an overgrowth of the gum tissue.

E. Sedation: This is not a common adverse effect of phenytoin. Phenytoin is more known for causing CNS-related side effects like nystagmus, ataxia, and dizziness.
