A nurse is administering penicillin to a client who has streptococcal pharyngitis. The nurse should monitor for which adverse effect of penicillin therapy?

Hypokalemia

Hyperglycemia

Anaphylaxis

Constipation.

Elevated platelet count.

Answer and Explanation

The Correct Answer is C

Anaphylaxis is a severe allergic reaction that can be life-threatening and requires immediate medical attention. Penicillin is one of the most common causes of anaphylaxis. Symptoms of anaphylaxis include difficulty breathing, swelling of the face, throat, or tongue, hives, itching, low blood pressure, and shock.

Choice A is wrong because hypokalemia (low potassium levels in the blood) is not a common or serious side effect of penicillin therapy. Hypokalemia can cause muscle weakness, cramps, irregular heartbeat, and fatigue.

Choice B is wrong because hyperglycemia (high blood sugar levels) is not a common or serious side effect of penicillin therapy. Hyperglycemia can cause thirst, frequent urination, blurred vision, and headaches.

Choice D is wrong because constipation is not a common or serious side effect of penicillin therapy. Constipation can cause abdominal pain, bloating, and difficulty passing stools.

Correct Answer is D

Explanation

This statement indicates a need for further teaching because linezolid should be taken for the full prescribed course of treatment, even if the symptoms improve or resolve.Stopping the medication too soon can lead to bacterial resistance or recurrence of the infection.

Choice A is wrong because it is a correct statement.Linezolid can cause optic neuropathy or vision changes, so patients should report any changes in their vision to their doctor.

Choice B is wrong because it is a correct statement.

Linezolid can interact with foods that contain tyramine, such as cheese and red wine, and cause a hypertensive crisis.Patients should avoid eating foods that contain tyramine while taking linezolid and for two weeks after stopping the medication.

Choice C is wrong because it is a correct statement.Linezolid can be taken with or without food, but taking it on an empty stomach may help with absorption and effectiveness.

A. Hypertension B. Tinnitus C. Mazzotti reaction D. Stevens-Johnson syndrome.

Correct Answer is C

Explanation

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.
