ECPI NUR 138 Pharmacology Exam 1
Questions and Answers 100% 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" - ✔✔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. - ✔✔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 - ✔✔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 - ✔✔C. A powder




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 - ✔✔B. Levothyroxine (Synthroid) tablets


C. Diphenhydramine (Benadryl) elixir


F. Esomeprazole (Nexium) capsules
