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. Therapeutic effects may take weeks: the onset of the antisecretory effect of omeprazole is usually achieved within one hour, but it may take up to 4 weeks for it to work fully.
B. This drug should not be taken for a prolonged period of time: prolonged use can lead to complications such as nutrient malabsorption and bone fractures.
C. This drug must be used with antacids to be effective: This is incorrect; omeprazole is a proton pump inhibitor and works independently of antacids.
D. This drug is safe for long-term use: Omeprazole is generally safe for short-term use, but long-term use should be carefully monitored due to potential risks (such as decreased bone density, vitamin B12 deficiency, and kidney disease). It is not considered safe for indefinite or unrestricted long-term use.

Correct Answer is ["250"]

Explanation

DesiredDose=250mg

AvailableConcentration=125mg/5mL

VolumetoAdminister=DesiredDose/AvailableConcentration × Volume

= 250 mg ÷ 125 mg/5mL

= 250/125 × 5mL

= 2 ×5mL

= 10 mL

So, the nurse should administer 10 mL.
