A nurse is reinforcing teaching with a client who is going to take guaifenesin, an expectorant, to help manage a cough. The nurse should explain that this type of medication treats coughs by which of the following mechanisms?

Stimulates and thins secretions

Suppresses the urge to cough

Reduces inflammation

Dries mucous membranes

Answer and Explanation

The Correct Answer is A

A. Guaifenesin works as an expectorant by stimulating and thinning respiratory tract secretions, making it easier for the client to cough up and clear mucus from the airways.
B. Suppressing the urge to cough is the action of antitussive medications, not expectorants like guaifenesin.
C. Guaifenesin does not have significant anti-inflammatory properties; its primary action is on mucus clearance.
D. Drying mucous membranes is not the mechanism of action for guaifenesin; it focuses on facilitating mucus removal.

Explanation

To administer the correct dose of aspirin, the nurse needs to calculate the number of 325 mg tablets that would equal the prescribed 650 mg dose. By dividing the prescribed dose (650 mg) by the strength of the available tablets (325 mg), we find that it equals exactly 2.

A. Ask the client to remain in a side-lying position with the affected ear down for several minutes after instillation. B. Pull the client's pinna down and back prior to instillation. C. Warm the medication to room temperature before administration. D. Press a cotton ball into the client's ear canal after instillation.

Correct Answer is C

Explanation

A. Asking the client to remain in a side-lying position comes after administering the drops to facilitate medication retention, but it's not the first action.
B. Pulling the client's pinna down and back straightens the ear canal, but this technique is used for children < 3years. For adults the pinna should be pulled upwards and outwards.
C. Warming the medication may not be necessary to prevent dizziness.
D. Placing a cotton ball in the ear canal after instillation is not necessary for otic medication administration and should not be done routinely.
