The nurse is teaching the use of crutches. The nurse knows that the client requires further teaching when making the following statement?

"I will go down the stairs with my bad leg first."

"I will adjust my crutches so that they are resting directly in my armpit."

"I will adjust my crutches 3 finger breadths below my armpits."

"I will go up the stairs with my good leg first."

Answer and Explanation

The Correct Answer is B

A. "I will go down the stairs with my bad leg first.": Teaching commonly uses the phrase “down with the bad” -the crutches and the weaker (bad) leg move down first, then the stronger leg follows, to provide the safest sequence.

B. "I will adjust my crutches so that they are resting directly in my armpit.": Crutches should not rest in the axilla; placing weight on the armpit risks axillary nerve and vascular injury. Weight should be supported by the hands on the handgrips, with the crutch tops positioned a couple of finger-breadths below the axilla.

C. "I will adjust my crutches 3 finger breadths below my armpits.": Proper crutch height is about 2–3 fingerbreadths (approximately 2–3 inches) below the axilla when standing, which prevents axillary pressure and allows weight-bearing through the hands.

D. "I will go up the stairs with my good leg first.": Teaching uses “up with the good” -the stronger (good) leg goes up first, then the crutches and the weaker leg follow, which helps maintain stability going up.

Correct Answer is D

Explanation

A. "First draw up the NPH insulin; then draw up the regular insulin in the same syringe.": Drawing the cloudy NPH first then the clear regular risks contaminating the regular insulin vial with NPH; this order increases the chance of altering the short-acting vial.

B. "First draw up and administer the regular insulin, then draw up and administer the NPH insulin.": Giving two separate injections (regular first, then NPH) would avoid mixing errors, but it increases number of injections; when mixing in one syringe, the usual safe procedure is still to draw the clear (regular) before the cloudy (NPH).

C. "First draw up and administer the NPH insulin. Wait at least 15 minutes; then draw up and administer the regular insulin.": Separating administration with a wait is unnecessary and may delay glucose control; also drawing NPH first still risks contaminating the regular vial if mixing is later attempted.

D. "First draw up the regular insulin; then draw up the NPH insulin in the same syringe.": When mixing regular (clear) and NPH (cloudy) in one syringe the standard technique is clear before cloudy -draw the regular insulin first, then the NPH -to avoid contaminating the short-acting vial and ensure accurate dosing.

A. Stomach B. Heart C. Liver D. Pancreas

Correct Answer is C

Explanation

A. Stomach: The stomach aids digestion and can contribute to absorption, but it is not the primary organ for systemic drug metabolism.

B. Heart: The heart circulates blood but is not a major site of drug metabolism.

C. Liver: The liver is the principal organ for drug metabolism (hepatic enzymatic biotransformation and the first-pass effect), making it central to how most medications are processed.

D. Pancreas: The pancreas produces digestive enzymes and hormones like insulin, but it is not the main organ responsible for medication metabolism.
