Which age-related physiological change puts a client at higher risk for adverse medication complications?
Reduced muscle mass.
Decreased renal function.
Slowed gastrointestinal motility.
Thinning of the layers of the skin.
The Correct Answer is B
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.

Correct Answer is D
Explanation
Cleanse from the innermost point outwards with a circular movement. This technique reduces the risk of contaminating the wound with bacteria from the surrounding skin.
Some possible explanations for the other choices are:
Choice A is wrong because hydrogen peroxide and betadine solution can damage healthy tissue and delay wound healing.
Choice B is wrong because cleansing the wound from the outer edges towards the center can introduce bacteria from the skin into the wound.
Choice C is wrong because using 4x4 gauze to the wound and surrounding skin three times can cause trauma and bleeding to the wound.
Normal ranges for pressure ulcer stages are:
- Stage I: A reddened, painful area on the skin that does not turn white when pressed.
- Stage II: The skin blisters or forms an open sore. The area around the sore may be red and irritated.
- Stage III: The skin develops an open, sunken hole called a crater or ulcer. The tissue below the skin is damaged.
- Stage IV: The pressure ulcer has become so deep that there is damage to the muscle and bone, and sometimes to tendons and joints.
Correct Answer is A
Explanation
Rhonchi. Rhonchi are low-pitched, rattling sounds that indicate mucus in the larger airways. They are most evident on expiration and may decrease after coughing.
Choice B is wrong because wheezes are high-pitched, squeaking sounds that indicate narrowed small air passages. They are usually heard on both inspiration and expiration.
Choice C is wrong because crackles are short, high-pitched popping sounds that indicate fluid or inflammation in the alveoli. They are usually heard on inspiration.
Choice D is wrong because pleural friction rubs are creaking or grating sounds that indicate inflammation of the pleura. They are usually heard on both inspiration and expiration and do not change with coughing.
