During antibiotic therapy, the nurse will monitor closely for signs and symptoms of a hypersensitivity reaction. Which of these assessment findings may be an indication of a hypersensitivity reaction? (Select all that apply.)

Shortness of breath

Black hairy tongue

Itching

Swelling of the tongue

Wheezing

Answer and Explanation

Correct Answer : A,C,D,E

Choice A rationale:

Shortness of breath is a common symptom of a hypersensitivity reaction. This occurs because the body’s immune system responds to a foreign substance, known as an antigen, by producing specific antibodies. This immune response can cause inflammation and swelling in various parts of the body, including the airways, leading to shortness of breath.

Choice B rationale:

A black hairy tongue is not typically associated with a hypersensitivity reaction. It is a condition that causes the tongue to appear black and hairy, and it’s usually caused by an overgrowth of bacteria or yeast on the tongue. It’s not related to allergies or hypersensitivity reactions.

Choice C rationale:

Itching is another common symptom of a hypersensitivity reaction. When the body encounters an antigen, it triggers an immune response that releases chemicals like histamine. Histamine can cause itching, among other symptoms.

Choice D rationale:

Swelling of the tongue can be a symptom of a severe hypersensitivity reaction known as anaphylaxis. This is a medical emergency that requires immediate attention. The swelling is caused by inflammation in response to an antigen.

Choice E rationale:

Wheezing is a symptom of a hypersensitivity reaction, specifically type I hypersensitivity. This type of reaction includes allergic disorders, which affect the lungs among other parts of the body. The immune response to an antigen can cause the airways to narrow and produce a wheezing sound.

Correct Answer is C

Explanation

Choice A rationale:

Blood glucose levels are not typically affected by rifampin and pyrazinamide. These medications are primarily used to treat tuberculosis and do not have a direct impact on blood sugar levels.

Choice B rationale:

Thyroid function studies are not usually required when a patient is on rifampin and pyrazinamide. These medications do not typically affect the thyroid gland or its function.

Choice C rationale:

Liver function tests are crucial when a patient is on rifampin and pyrazinamide. Both of these medications can cause liver problems, including hepatitis. Therefore, regular monitoring of liver function is necessary to detect any potential damage early and adjust the treatment plan accordingly.

Choice D rationale:

Gallbladder studies are not typically required for patients on rifampin and pyrazinamide. These medications do not have a known direct impact on the gallbladder.

A. Erythromycin B. Amphotericin B C. Amoxicillin-clavulanate D. Gentamicin E. Choice D rationale:

Correct Answer is C

Explanation

Choice A rationale:

Erythromycin Erythromycin is a macrolide antibiotic that is often used as an alternative to penicillin. It is generally safe for use in patients with a penicillin allergy. It works by inhibiting bacterial protein synthesis and is effective against a wide range of bacteria.

Choice B rationale:

Amphotericin B Amphotericin B is an antifungal medication, not an antibiotic. It is used to treat serious, systemic fungal infections. It has no cross-reactivity with penicillin, so it would not be a concern for a patient with a penicillin allergy.

Choice C rationale:

Amoxicillin-clavulanate Amoxicillin-clavulanate is a type of penicillin antibiotic. Patients with a known penicillin allergy should avoid this medication, as they may have a cross-reactivity to it. This is why the nurse should verify this prescription with the provider.

Choice D rationale:

Gentamicin Gentamicin is an aminoglycoside antibiotic used to treat serious bacterial infections caused by gram-negative bacteria. It is not related to penicillin and would be safe for a patient with a penicillin allergy.
