LVN Pharmacology exam V questions
n answers rated A+
ch. 41 - ANS ✔✔drugs that effect the gastrointestinal system
antiemetics - ANS ✔✔Medications used prevent or stop nausea/vomiting
motion sickness drugs - ANS ✔✔buclizine (Buc Ladin)
cyclizine (Mare zine)
diphenhydramine (Benadryl)
dimenhydrinate (Dramamine)
meclizine (Antivert)
scopolamine (Scopace-oral, Transderm-Scop-patch)
antiemetics- specific uses - ANS ✔✔before surgery to prevent vomiting during service
immediately after surgery when the pt is recovering from anesthesia
before, during, and after administration of antineoplastic drugs that induce a high degree of
nausea and vomiting
during radiation therapy when the GI tract is in the treatment field
bacterial and viral infections and adverse drug reactions
vertigo and motion sickness
nursing diagnosis for GI system- drugs - ANS ✔✔risk for deficient fluid volume R/T diarrhea,
nausea, & vomiting
imbalanced nutrition: less than body requirements R/T impaired ability to ingest and retain food
and liquids, or offensive tastes and smells
, individual effective therapeutic regimen management R/T inability to take oral form of
medication
Risk for injury R/T adverse effects of drowsiness
plan of care - ANS ✔✔depends on the reason for the upper GI drug administered
nursing implications for antiemetics - ANS ✔✔Antiemetics are administered regularly in the
hospital and home to decrease chemotherapy-related nausea, vomiting, and retching.
Managing these side-effects requires superior assessment skills and extensive knowledge of
pharmacologic actions. Patient and family education on antiemetics is essential in light of
increased administration of outpatient chemotherapy
Z-track technique of IM injection - ANS ✔✔used when a drug is highly irritating to tissues or has
the ability to permanently stain the skin
Z-track procedure - ANS ✔✔draw the drug up into the syringe
discard the needle and place a new needle (on the syringe to prevent any solution that may
remain in the needle from contacting tissues as the needle is put into the muscle)
pull the plunger down to draw approx. 0.1 - 0.2 mL of air into the syringe (air bubble in the
syringe follows the drug into the tissues and seals off the area where the drug was injected
place pt in correct position for administration of an IM injection
cleanse the skin
pull the skin, sub q tissues and fat (that lie over the injection site) laterally, displacing the tissue
to the side (aprox. 1 inch)
Z- track procedure contd - ANS ✔✔while holding the tissues in the lateral position, insert the
needle at a 90 degree angle and inject drug
after drug is injected, wait 10 seconds to permit the medication to disperse into the muscle
tissue, then release the tissue while withdrawing the needle (this technique prevents the
backflow of drug into the sub q tissue
