Which prescription written by a health care provider for an eye drop medication is written correctly?
One drop od tid.
One drop ou daily.
One drop right ear bid.
One drop left eye daily.
The Correct Answer is D
One drop left eye daily.
This is because it uses the correct abbreviation for left eye (os) and the correct frequency (daily).
The other choices are wrong because:
Choice A uses od which means right eye, not once daily.
Choice B uses ou which means both eyes, not each eye.
Choice C uses right ear which is not an eye drop medication. Some common eye drop prescription abbreviations are:
- gt or gtt for drop or drops
- od for right eye
- os for left eye
- ou for both eyes
- bid for twice a day
- tid for three times a day
- qid for four times a day
- prn for as needed

Correct Answer is B
Explanation
This outcome indicates that the client has resolved their constipation and has a regular pattern of defecation without difficulty or discomfort.
Choice A is wrong because taking a laxative daily can worsen constipation by causing dependency and reducing the natural peristalsis of the colon.
Choice C is wrong because requesting a bedpan every four hours does not necessarily mean that the client has bowel movements. It may indicate that the client has difficulty passing stool or has a sensation of incomplete emptying.
Choice D is wrong because having a bowel movement within 72 hours is still considered constipation. Constipation is diagnosed when bowel movements are associated with at least two of the following symptoms, occurring in the past three months with an onset of symptoms of at least six months: Less than three spontaneous bowel movements per week, Lumpy or hard stools from at least 25% of bowel movements.
Correct Answer is B
Explanation
This is because older adults have a reduced ability to excrete drugs and their metabolites through the kidneys, which can lead to drug accumulation and toxicity. Decreased renal function can also affect the pharmacokinetics and pharmacodynamics of many drugs, altering their absorption, distribution, metabolism, and elimination.
Choice A is wrong because reduced muscle mass does not directly affect drug metabolism or clearance, although it may affect the volume of distribution of some drugs that are highly protein-bound or lipophilic.
Choice C is wrong because slowed gastrointestinal motility does not increase the risk of adverse drug events in older adults, although it may affect the rate and extent of drug absorption.
Choice D is wrong because thinning of the layers of the skin does not affect drug metabolism or clearance, although it may increase the risk of skin infections or injuries.
