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 B

Explanation

This is because antibiotics act synergistically with the immune system to subdue infection, and it is critical for success that the host defenses are adequate.

Choice A is wrong becauseAge is wrong because age is a general factor that must be considered when choosing any medication, not just antimicrobials.

Choice C is wrong becauseGenetic heritage is wrong because genetic heritage is also a general factor that may affect the metabolism and excretion of medications, not the selection of antimicrobials.

Choice D is wrong becausePrevious medication reactions is wrong because previous medication reactions are also a general factor that may indicate allergies or intolerances to certain medications, not the selection of antimicrobials.

Normal ranges for immune function vary depending on the type and level of immunity measured, such as innate, adaptive, humoral or cellular immunity.Some common tests for immune function include complete blood count (CBC), immunoglobulin levels, complement levels, antibody titers and skin tests.

Normal ranges for these tests depend on the laboratory and the method used, but some examples are:

• CBC: white blood cell count 4.5-11 x 10^9/L; neutrophils 40-75%; lymphocytes 20-50%; monocytes 2-10%; eosinophils 1-6%; basophils 0-2%.

• Immunoglobulin levels: IgG 7-16 g/L; IgA 0.7-4 g/L; IgM 0.4-2.3 g/L; IgE 0-0.4 g/L.

• Complement levels: C3 0.9-1.8 g

A. Serum creatinine B. Serum potassium C. Serum calcium D. Serum glucose.

Correct Answer is A

Explanation

Gentamicin is an aminoglycoside antibiotic that can cause nephrotoxicity, which is damage to the kidneys.Serum creatinine is a measure of kidney function and should be monitored closely during gentamicin therapy. The normal range for serum creatinine is 0.6 to 1.2 mg/dL for men and 0.5 to 1.1 mg/dL for women.

Choice B is wrong because serum potassium is not affected by gentamicin.

The normal range for serum potassium is 3.5 to 5.0 mEq/L.

Choice C is wrong because serum calcium is not affected by gentamicin.

The normal range for serum calcium is 8.5 to 10.2 mg/dL.

Choice D is wrong because serum glucose is not affected by gentamicin.

The normal range for serum glucose is 70 to 110 mg/dL.
