AND QUESTIONS SET A+
✔✔A lVN is preparing to administer phenytoin (Dilantin) to a patient with a history of
partial seizures. The nurse is going to administer the phenytoin (Dilantin) and
ondansetron (Zofran) via IV at the same time. Why did the RN stop the LVN prior to the

when administered via IV.
Also, phenytoin (Dilantin) must be pushed slowly to avoid hypotension.
Check renal and liver functions often.
✔✔Which insulin is cloudy in appearance? - ✔✔Only intermediate acting NPH insulin
(Humulin N, Novolin N) is cloudy in appearance.
✔✔How should the nurse prepare the insulin prior to administering it to a patient? -
✔✔Roll the intermediate acting NPH insulin to mix it's content.
Add air into the intermediate action NPH insulin (Humulin N, Novolin N).
Then add air into the short acting aka regular insulin (lispro Humalog, aspart (Novolog),
glulisine (Apidra).
Then draw up the shorting acting insulin then draw up the intermediate acting insulin.
✔✔Which type of insulin has an onset of 5-15 minutes and a peak time of 30-60
minutes? - ✔✔Rapid Acting Insulin:
aspart (Novolog)
lispro (Humalog)
glulisine (Apidra)

Humulin R
Novulin R
Velosulin
