PASS.
The patient is to receive oral guaifenesin (Mucinex) twice a day. Today, the nurse was busy and
gave the medication 2 hours after the scheduled dose was due. What type of problem does this
represent?
A. "Right route"
B. "Right medication"
C. "Right dose"
D. "Right time" - ANS D. "Right time"
Rationale: "Right time" is correct because the medication was given more than 30 minutes after
the scheduled dose was due. "Dose" is incorrect because the dose is not related to the time the
medication administration is scheduled. "Route" is incorrect because the route is not affected.
"Medication" is incorrect because the medication ordered will not change.
The nurse is administering parenteral drugs. Which statement is true regarding parenteral
drugs?
A. Parenteral drugs bypass the first-pass effect.
B. Absorption of parenteral drugs is affected by reduced blood flow to the stomach.
C. Absorption of parenteral drugs is faster when the stomach is empty.

,D. Parenteral drugs exert their effects while circulating in the bloodstream. - ANS A.
Parenteral drugs bypass the first-pass effect.
Rationale: Drugs given by the parenteral route bypass the first-pass effect. Reduced blood flow
to the stomach and the presence of food in the stomach apply to enteral drugs (taken orally),
not to parenteral drugs. Parenteral drugs must be absorbed into cells and tissues from the
circulation before they can exert their effects: they do not exert their effects while circulating in
the bloodstream.
The nurse is administering medications to the patient who is in renal failure resulting from end-
stage renal disease. The nurse is aware that patients with kidney failure would most likely have
problems with which pharmacokinetic phase?
A. Excretion
B. Absorption
C. Metabolism
D. Distribution - ANS A. Excretion
Rationale: The kidneys are the organs that are most responsible for drug excretion. Renal
function does not affect the absorption and distribution of a drug. Renal function may affect
metabolism of drugs to a small extent.
The patient is complaining of a headache and asks the nurse which over-the-counter medication
form would work the fastest to help reduce the pain. Which medication form will the nurse
suggest?
A. A tablet
B. A capsule
C. A powder
D. An enteric-coated tablet - ANS C. A powder
2026 STUDY MATERIAL @COPYRIGHT RESERVED 2
, Rationale: Of the types of oral medications listed, the powder form would be absorbed the
fastest, thus having a faster onset. The tablet, the capsule, and, finally, the enteric-coated tablet
would be absorbed next, in that order.
Which drugs would be affected by the first-pass effect? (Select all that apply.)
A. Sublingual nitroglycerin tablets
B. Levothyroxine (Synthroid) tablets
C. Diphenhydramine (Benadryl) elixir
D. Penicillin given by IV piggyback infusion
E. Morphine given by IV push injection
F. Esomeprazole (Nexium) capsules
G. Transdermal nicotine patches - ANS B. Levothyroxine (Synthroid) tablets
C. Diphenhydramine (Benadryl) elixir
F. Esomeprazole (Nexium) capsules
For accurate medication administration to pediatric patients, the nurse must take into account
which criteria?
A. Renal output
B. Height
C. Body temperature
D. Organ maturity - ANS D. Organ maturity
Rationale: To administer medications to pediatric patients accurately, one must take into
account organ maturity, body surface area, age, and weight. The other options are incorrect:
renal output and body temperature are not considerations, and height alone is not sufficient.
During discharge patient teaching, the nurse reviews prescriptions with a patient. Which
statement is correct about refills for an analgesic that is classified as Schedule C-III?
