Adverse effects and toxicity
Adverse effects and toxicity ( 5 Questions)
A nurse is teaching a client who is prescribed doxycycline (Vibramycin) for Lyme disease. The nurse instructs the client to avoid exposure to sunlight while taking this drug because it may cause photosensitivity.
Which statement by the client indicates understanding of this instruction?
This statement indicates that the client understands that doxycycline can cause photosensitivity, which is a heightened skin sensitivity or unusual reaction when exposed to UV radiation from the sun or a tanning bed. Photosensitivity can cause damage at the DNA level, painful sunburn-like erythema, blistering, lichenoid eruptions, and photo-onycholysis. The client should avoid excessive sun exposure and use photoprotection methods against both UVB and UVA wavelengths.
Choice B is wrong because taking the drug at night before bed does not prevent photosensitivity during the day. The drug or its metabolites can remain in the skin for several days after ingestion.
Choice C is wrong because drinking plenty of fluids to prevent dehydration is not related to photosensitivity.
Dehydration can occur due to other causes such as vomiting, diarrhea, fever, or excessive sweating.
Choice D is wrong because stopping the drug if a rash develops is not advisable.
The rash could be a sign of photosensitivity or an allergic reaction, and the client should consult their doctor before discontinuing the medication.
Stopping the drug abruptly could also lead to treatment failure or bacterial resistance.
