A nurse is preparing to administer ivermectin to a client who has onchocerciasis (river blindness).
Which of the following adverse effects should the nurse monitor for in this client?
Hypertension
Tinnitus
Mazzotti reaction
Stevens-Johnson syndrome.
The Correct Answer is C
A Mazzotti reaction is a severe inflammatory response that can occur after taking ivermectin for onchocerciasis (river blindness), a parasitic infection caused by Onchocerca volvulus. The reaction is due to the death of the microfilariae (larvae) of the parasite and can cause fever, rash, itching, joint pain, swollen lymph nodes, and eye inflammation.
Choice A is wrong because hypertension is not a common adverse effect of ivermectin. Hypotension, however, can occur in some cases.
Choice B is wrong because tinnitus is not a common adverse effect of ivermectin. Tinnitus is a ringing or buzzing sound in the ears that can be caused by various factors, such as exposure to loud noise, ear infections, or certain medications.
Choice D is wrong because Stevens-Johnson syndrome is not a common adverse effect of ivermectin.
Stevens-Johnson syndrome is a rare but serious skin reaction that can be triggered by infections or medications.
It causes blisters and peeling of the skin and mucous membranes.
