Questions and Correct Answers, With
Rationale.2024/2025.
A client is prescribed phenobarbital sodium (Luminal) for a seizure disorder. The
medication has a long half-life of 4 days. Based on this half-life, the medication
will most likely be prescribed
A. once a day.
B. twice a day.
C. three times a day.
D. four times a day.
ANS: A
Medication with long half-lives remain at their therapeutic levels between doses for long
periods of time. Therefore, this medication can be administered once a day.
A nurse educator is reviewing medication dosages and factors that influence
medication metabolism with a group of nurses. Medication dosages may need to
be decreased for which of the following reasons? (Select all that apply.)
A. Increased renal excretion
B. Increased medication-metabolizing enzymes
C. Liver failure
D. Peripheral vascular disease
E. Concurrent use of medication metabolized by the same pathway
ANS: C, E
Liver failure decreases metabolism and thus increase the concentration of medication.
This may require decreasing the dosage of medication. When two medications are
metabolized in the same way, they may compete for metabolism, thereby increasing the
concentration of one or both medications.
Increased renal excretion may decrease concentration of the medication, requiring
increased dosage. Increased medication-metabolizing enzymes can decrease the
concentration of the medication. The dose might need increased. Peripheral vascular
disease may impair distribution, and more of the medication may be needed.
A nurse s preparing to administer eye drops to a client. Which of the following are
appropriate nursing interventions related to this procedure? (Select all that

ANS: C

The skin should be washed with soap and water and dried thoroughly before applying a
transdermal patch. Application sites should be rotated on a daily basis to prevent skin
irritation.

B. Tachycardia
C. Palpable, hard mass above insertion site
D. Cool, pale skin

B. Select the back of the client's hand to insert the IV catheter.
C. Distend the veins by using a blood pressure cuff.
D. Direct the client to raise his arm above his heart.
ANS: C
The nurse should distend the veins using a blood pressure cuff to reduce overfilling of
the vein, which can result in a hematoma.
The nurse should remove excess hair by clipping it with scissors. Shaving with
disposable razors can cause skin damage that lead to infection. In most instances, the
nurse inserts the IV catheter into a distal site, such as the back of the client's hand.
However, when inserting an IV catheter for an older adult, the nurse should use a site
on the arm because older adults typically have fragile veins in the back of their hands.
