A patient is receiving a glucocorticoid medication to treat an exacerbation of COPD and the provider has ordered a slow taper in order to discontinue this medication. The nurse explains to the patient that this is done to prevent which condition?

A. “Drink extra water while taking this medication.”

This is correct. Guaifenesin is an expectorant that works by thinning and loosening mucus in the airways. Drinking extra water helps to enhance its effectiveness by keeping the patient well-hydrated.

B. “Monitor urine output closely.”

Monitoring urine output is not typically necessary with guaifenesin. It does not have a diuretic effect, and excessive monitoring of urine output may not be relevant in this context.

C. “Take it with an oral antihistamine for better effectiveness.”

Guaifenesin is often used in combination with other medications, but taking it with an oral antihistamine is not a standard recommendation. The combination should be based on the specific guidance of the healthcare provider.

D. “Avoid driving or using heavy machinery while on this medication.”

Guaifenesin does not typically cause sedation or impairment, so there is generally no need to avoid driving or using heavy machinery. This instruction may not be necessary for this medication.

A. Take this medication at bedtime because it causes drowsiness.

Oxymetazoline is not known to cause drowsiness. It is a nasal decongestant that works by constricting blood vessels in the nasal passages to alleviate congestion.

B. This medication should only be used for asthma.

Oxymetazoline is not a medication specifically used for asthma. It is primarily used as a nasal decongestant for relieving nasal congestion associated with conditions such as allergies and the common cold.

C. Limit the use of this medication to 3 days to prevent rebound nasal congestion

Oxymetazoline is a nasal decongestant commonly used to relieve nasal congestion due to conditions like seasonal allergies or the common cold. Prolonged use of nasal decongestant sprays like oxymetazoline can lead to rebound congestion, where the nasal passages become more congested when the medication is stopped. Therefore, it is important to limit the use of oxymetazoline to a short duration (typically 3 days) to avoid this rebound effect.

D. Stop this medication immediately.

Abruptly stopping oxymetazoline is not recommended, as it may lead to rebound congestion. The nurse should advise the client to follow the recommended duration of use and, if needed, consult with a healthcare provider before discontinuing the medication.
