Medication Administration - Exam Verified Questions And Answers LATEST UPDATE// Medication Administration


A nurse is preparing to administer an IM injection to a client who is overweight. Which of the following sites should the nurse select for the injection?

a. the lower, medial quadrant of the buttock near the coccyx b. the side hip between the iliac crest and anterior iliac spine c. the tissue of the posterior upper arm d. the lower, inner thigh 4 finger widths above the patella - CORRECT ANSW-b. the side hip between the iliac crest and anterior iliac spine

Ventrogluteal injection: the nurse should prepare for injection by placing a hand on the client's greater trochanter (right hand on left hip, for example) with the first two fingers touching the iliac crest and anterior superior iliac spine, forming a "V" shape.

a. dorsogluteal site poses greater risks (sciatic nerve) c. this site would appropriate for subQ injections d. to inject in the vastus laterals site, the nurse should select one hand width below the greater trochanter and one hand width above the patella

Classification of medications - CORRECT ANSWBased on:

- effects on body system - symptoms relieved by medication - medication's desired effect

Pharmacokinetics - CORRECT ANSW-The study of how medications enter the body, reach their site of action, metabolize, and exit the body.

ADME

Absorption - CORRECT ANSW-Passage of medication molecules into the blood from the site of administration

Factors that alter absorption: - route - ability of medication to dissolve - blood flow to site of administration - body surface area (increased surface area = increased absorption) - lipid solubility of medication (BBB)

Distribution - CORRECT ANSW-After absorbed, the medication is distributed to body tissues/organs (the site of action)

Rate/extent depends on:
- physical/chemical properties of medication - physiology of client ** circulation (blood flow to liver decreases with age) ** membrane permeability ** protein binding (decreased albumin with age)

Metabolism - CORRECT ANSW-Metabolized into a less potent/inactive form

Biotransformation: enzymes detoxify, break down, & remove active chemicals

Occurs mostly in the liver, but also in the kidneys, blood, intestines, & lungs

Excretion - CORRECT ANSW-Medications are excreted by the: - kidneys - liver - bowel - lungs - exocrine glands

Chemical makeup of medication determines organ of excretion

Therapeutic effect - CORRECT ANSW-expected or predicted physiological response that a medication causes
