A nurse is reinforcing teaching with a client regarding application of antiembolic stockings. Which of the following statements by the client indicates an understanding of the teaching?

The correct answer is 1.5 mL. Here is the explanation:

To calculate the amount of mL to administer, the nurse should use the following formula:

mL = (units ordered / units available) x mL available

Plugging in the values from the question, we get:

mL = (15,000 / 10,000) x 1

mL = 1.5 x 1

mL = 1.5

Therefore, the nurse should administer 1.5 mL of heparin with each dose.

Choice A reason: Withholding the medication if the systolic blood pressure is less than 90 mm Hg is an appropriate action, as propranolol is a beta-blocker that can lower blood pressure and cause hypotension, which can impair tissue perfusion and cause dizziness, fainting, or shock.

Choice B reason: Requesting a dosage increase if the apical heart rate is less than 60/min is an inappropriate action, as propranolol can slow down the heart rate and cause bradycardia, which can lead to fatigue, weakness, or cardiac arrest. The nurse should monitor the apical pulse before administering propranolol and withhold it if it is less than 60/min.

Choice C reason: Informing the client to expect increased hair growth is an incorrect statement, as propranolol does not cause hypertrichosis or excessive hair growth. However, another beta-blocker, minoxidil, can cause this side effect.

Choice D reason: Administering the medication with an antacid is not an appropriate action, as antacids can interfere with the absorption of propranolol and reduce its effectiveness. The nurse should administer propranolol on an empty stomach or with food that does not contain antacids.
