Frequently
Asked Questions
Chapter 30: Medication Administration
What are some examples of the types of oral medication
preparations that require special considerations for administration?
Examples of
the special considerations for administration some types of oral
medication preparations require include (1) chewable tablets must
be chewed thoroughly before swallowing because chewing enhances
gastric absorption, (2) buccal and sublingual medications must dissolve
completely before the client can eat or drink, and (3) suspensions
and emulsions should be administered immediately after shaking and
pouring from a bottle.
What
is the affect of age on pharmacokinetics?
Absorption of
oral medications is delayed in young infants because they have less
gastric acidity than adults. Infants also have a lower protein-binding,
allowing a greater amount of “free” medications in the
blood. The infant’s urine is also less acid, slowing the excretion
of certain medications in the urine.
Older people
often have more body fat, so fat soluble medications have a longer
half-life and longer duration of action. Water soluble medications
are more concentrated because older people have less body water.
Due to decreased liver or liver functioning, medication is metabolized
and eliminated slower in older people, resulting in a greater number
of side effects and drug toxicities. Some of the medications often
prescribed for older people, such as medication for gastric acid
reflux, slow absorption of other medications.
Why
are peak and trough drug levels measured?
Peak and trough
drug levels are measured in clients who are on medications that
are toxic to the kidneys or the ears. The prescribing practitioner,
knowing a client’s peak and trough levels, can adjust doses
of medication to maintain a therapeutic drug level and avoid a toxic
level.
In a
hospital, what happens after the prescriber orders a medication?
After the prescriber
orders a medication in the hospital, the nurse checks the order
for completeness and clarity and the nurse or ward clerk transcribes
the order, sending it on to the pharmacist. The pharmacist processes
the order, clarifies any unclear material, and prepares the medication.
Pharmacists monitor medications for incompatibilities, appropriate
timing, and appropriate dosage. The nurse is responsible for understanding
the actions of a drug and questioning any orders that are not clear
or appear to be inappropriate. Nurses teach clients and families
about the medications. They administer medications according to
“Five Rights:” the right medication to the
right client, in the right dose, by the right route, at the right
time.
How
can the nurse protect the safety of clients when administering medications?
The nurse protects
the safety of clients when administering medications by (1) following
the “five rights” of medication administration; (2)
asking another nurse or the pharmacist to check drug calculations;
(3) checking the placement of the decimal point of the dose ordered
or calculated]; (4) understanding the client’s history and
the actions, side effects, and doses of medications given; (5) asking
for clarification of any orders; (6) not leaving medications at
the bedside for the client to take; (7) checking the client’s
name band before administering medications; (8) teaching clients
about the medications they take; and (9) consulting the pharmacist
and drug references for any questions.
