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.

Answer and Explanation

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.

Correct Answer is ["A","B","C"]

Explanation

Oxacillin, erythromycin and clindamycin are all antibiotics that are sensitive to Staphylococcus aureus according to the culture and sensitivity report.

This means that they can inhibit or kill the bacteria that are causing the wound infection.These antibiotics belong to different classes of drugs that have different mechanisms of action and spectrum of activity.

Choice D and E are wrong because vancomycin and linezolid are antibiotics that are usually reserved for more resistant strains of Staphylococcus aureus, such as methicillin-resistant Staphylococcus aureus (MRSA) or

A. Antibiotic guidelines in critical care reduce the hospital length of stay. B. Inappropriate antibiotic use leads to the emergence of resistance. C. Antibiotic dosing has little effect on antimicrobial resistance. D. An antibiotic stewardship programme leads to an increase in antimicrobial resistance.

Correct Answer is B

Explanation

Inappropriate antibiotic use leads to the emergence of resistance.This is a well-established fact that is supported by the CDC and other organizations.Resistance can occur when antibiotics are used unnecessarily, excessively, or incorrectly, and can lead to infections that are harder to treat and more costly.

Choice A is wrong because antibiotic guidelines in critical care do not necessarily reduce the hospital length of stay.Although some studies have suggested that adherence to pneumonia guidelines may improve outcomes in severe pneumonia, other studies have found no significant effect of antibiotic stewardship on hospital length of stay or mortality in critically ill patients.

Therefore, this statement is not universally true.

Choice C is wrong because antibiotic dosing has a significant effect on antimicrobial resistance.Optimal dosing of antibiotics can help eradicate infections, prevent relapse, and minimize the selection of resistant bacteria.Conversely, suboptimal dosing can lead to treatment failure, prolonged infection, and increased resistance.

Therefore, antibiotic dosing should be carefully adjusted according to the pharmacokinetic and pharmacodynamic properties of the drug and the patient.

Choice D is wrong because an antibiotic stewardship programme leads to a decrease in antimicrobial resistance, not an increase.An antibiotic stewardship programme is a coordinated effort to improve and measure the appropriate use of antibiotics by promoting the selection of the optimal drug regimen, dose, duration, and route of administration.Such programmes have been shown to reduce antibiotic consumption, resistance rates, adverse events, and costs in various settings.

Therefore, this statement is false.
