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

Stimulates secretions

Suppresses the urge to cough

Reduces inflammation

Dries mucous membranes

Answer and Explanation

The Correct Answer is A

A. Stimulates secretions: Expectorants work by thinning and loosening mucus in the airways, making it easier to cough up and clear out. This mechanism helps to reduce cough by facilitating the removal of mucus.
B. Suppresses the urge to cough: Cough suppressants, or antitussives, work by suppressing the cough reflex, not by stimulating secretions. This choice describes a different type of medication used for dry, unproductive coughs.
C. Reduces inflammation: Anti-inflammatory medications reduce inflammation, but they do not specifically target mucus production or the cough reflex. Expectorants do not primarily work by reducing inflammation.
D. Dries mucous membranes: Drying mucous membranes would typically be the action of antihistamines or decongestants, which are not the primary mechanism of action for expectorants. Expectorants aim to keep mucus hydrated to facilitate its removal.

Correct Answer is B

Explanation

A. ConstipationL Constipation is not a common adverse effect of oxymetazoline, which is a nasal decongestant.
B. Nasal congestion: This is correct. Prolonged use of oxymetazoline can lead to rebound congestion, where the nasal passages become more congested when the medication is stopped.
C. Productive cough: A productive cough is not associated with oxymetazoline use.
D. Sedation: Oxymetazoline does not typically cause sedation; it is a topical decongestant.

Correct Answer is ["10"]

Explanation

VolumetoAdminister=DesiredDose/AvailableConcentration × Volume

=10 mg ÷20mg/5mL

= 10/20 × 5mL

= 0.5×5mL

=2.5mL

So, the nurse should administer 2.5 mL.
