A client is receiving Dextromethorphan (Robitussin). The nurse knows the drug is exerting its therapeutic effects with which client report?

A. Cardiac Enzymes

Cardiac enzymes are markers used to assess heart health and are not directly related to myelosuppression caused by chemotherapy. Monitoring cardiac enzymes is important for assessing heart function but is not the primary concern in the context of myelosuppression.

B. Complete Blood Count with differential

This is the correct choice. The complete blood count (CBC) with differential provides information about the levels of red blood cells, white blood cells, and platelets. Since myelosuppression affects blood cell production, monitoring the CBC with differential is crucial to detect and manage any abnormalities in these cell counts.

C. Chemistry Profile

A chemistry profile typically includes measurements of electrolytes, kidney function, and other metabolic parameters. While monitoring overall health is important, the specific concern with myelosuppression and chemotherapy is related to blood cell counts. Therefore, a complete blood count (CBC) is more directly relevant in this context than a chemistry profile.

D. Liver Function Tests

Liver function tests assess the health of the liver and are not directly related to myelosuppression caused by chemotherapy. These tests are important in certain situations, but they do not provide information about blood cell counts, which are the primary concern when dealing with myelosuppression.

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.
