CORRECT!!!
Question: If a healthcare provider orders a medication with a half-life ($t_{1/2}$)
exceeding 24 hours to be administered more frequently than once a day, why
should the nurse question the order?
A. Once daily
B. Every other day
C. Twice weekly
D. Once weekly
Answer: ✔️✔️ A. Once daily. Drugs with long half-lives stay in the system longer;
giving them more than once a day risks toxic accumulation. As a rule, the dosing
interval usually correlates with the drug's half-life.
Question: While reviewing a patient's chart, a nurse identifies a medication with a
"low therapeutic index." What is the most critical nursing implication regarding
this finding?
A. The drug has a wide margin of safety.
B. The drug has a narrow margin of safety.
C. Blood levels should be measured 1 hour after administration.
D. Blood levels should be measured 10 minutes after administration.
Answer: ✔️✔️ B. A narrow margin of safety. A low therapeutic index means the
difference between a therapeutic dose and a toxic dose is very small, requiring
extremely close monitoring of the patient and their blood plasma levels.
, Therapeutic index refers to the level at which a drug is more helpful than harmful.
If there is a low therapeutic index, then there is a narrow margin of safety.
Which of the following nurse actions should be most appropriate for ensuring
client safety with a medication that has a low therapeutic index?
A. Monitoring a patient's urine output
B. Assessing vital signs hourly
C. Maintaining strict isolation precautions
D. Monitoring serum peak and trough levels -ANSWER✔️✔️D. Monitoring serum
peak and trough levels.
Due to having a narrow margin of safety and effectiveness, the levels of
medication in the blood need to be as consistent as possible.
The nurse reviews the client's medication regimen, including interval of drug
dosage, which is related to which of the following?
A. Stimulation of the receptors
B. Trough level
C. Therapeutic index
D. Half life -ANSWER✔️✔️D. Half life
Half life is determined by when the medication they are taking is only half in their
blood stream. This is the safest and most effective point of replenishing medication
in the body system. This leads to understanding the interval of which a drug should
be administered.
