1.
A nurse is administering a medication to a patient and wants to
ensure that the medication is given to the correct individual.
Which medication-administration right addresses this
responsibility?
A. Right dose
B. Right route
C. Right patient
D. Right documentation
Rationale: The right patient requires the nurse to verify the
patient's identity using appropriate identifiers before medication
administration. This helps prevent medication errors involving the
wrong individual.
2.
,A patient asks why a medication administered intravenously
produces effects faster than the same medication taken orally.
Which pharmacokinetic principle best explains this?
A. Increased protein binding
B. Delayed absorption
C. Direct entry into systemic circulation
D. Increased hepatic metabolism
Rationale: Intravenous medications enter the bloodstream
directly and therefore bypass the absorption process. This
generally produces a rapid onset of action compared with oral
administration.
3.
Which organ is primarily responsible for the metabolism of most
medications?
A. Heart
B. Lungs
C. Kidneys
D. Liver
Rationale: The liver is the major site of drug metabolism. Hepatic
enzymes, particularly those of the cytochrome P450 system,
chemically modify many medications to facilitate their
elimination.
4.
,A nurse is caring for a patient receiving a medication that is highly
protein bound. Which condition may increase the amount of free
medication in the bloodstream?
A. Increased albumin production
B. Decreased serum albumin
C. Increased renal perfusion
D. Increased gastrointestinal motility
Rationale: Many medications bind to albumin in the blood. When
albumin levels decrease, less medication is protein bound and
more remains free and pharmacologically active, potentially
increasing the risk of toxicity.
5.
Which organ is primarily responsible for the elimination of many
medications and their metabolites?
A. Liver
B. Pancreas
C. Kidneys
D. Spleen
Rationale: The kidneys eliminate many drugs through glomerular
filtration, tubular secretion, and tubular reabsorption. Impaired
renal function can cause medications or metabolites to
accumulate.
6.
, A medication has a half-life of 8 hours. Approximately how much
of the medication remains in the body after 16 hours, assuming
no additional doses are given?
A. 75%
B. 50%
C. 25%
D. 10%
Rationale: One half-life reduces the amount of medication by
approximately 50%. After 8 hours, 50% remains; after another 8
hours, approximately 25% remains.
7.
Which term describes the time required for a medication to
produce its first measurable therapeutic effect?
A. Duration
B. Peak
C. Onset
D. Half-life
Rationale: Onset is the time between administration of a
medication and the beginning of its therapeutic effect. Peak refers
to the time when the medication reaches its maximum effect.
8.
A patient receiving an antibiotic develops wheezing, facial
swelling, and difficulty breathing. What should the nurse do first?
A. Document the reaction
B. Administer the next scheduled dose
