A nurse is assisting with the care of a client who is receiving penicillin via intermittent IV bolus.Which of the following should the nurse recognize as a clinical manifestation of anaphylaxis?

Peripheral edema.

Pallor.

Hypertension.

Pruritus.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Peripheral edema is swelling in the tissues due to fluid accumulation, often related to heart or kidney issues, not typically a sign of anaphylaxis.

Choice B rationale

Pallor refers to paleness and is usually a sign of anemia or shock, not specifically linked to anaphylaxis.

Choice C rationale

Hypertension, or high blood pressure, is not a common manifestation of anaphylaxis. Anaphylaxis typically causes hypotension, or low blood pressure.

Choice D rationale

Pruritus, or severe itching, is a common clinical manifestation of anaphylaxis due to the release of histamines in the body.

Correct Answer is B

Explanation

Choice A rationale

Exercise can increase pressure in the middle ear and should be avoided until cleared by a healthcare provider. Engaging in physical activities too soon can impair the healing process after tympanoplasty.

Choice B rationale

Closing the mouth while sneezing reduces the risk of pressure changes in the middle ear, which could disrupt the surgical repair. The client should also avoid actions that can increase ear pressure, such as blowing their nose forcefully.

Choice C rationale

Shampooing hair can introduce water into the ear, potentially causing infection or damage to the surgical site. The client should follow the healthcare provider’s instructions regarding when it is safe to resume washing their hair.

Choice D rationale

Drinking through a straw creates negative pressure that can affect the middle ear and the healing process. The client should avoid using straws and other activities that create pressure changes in the ear.

A. Adverse effects occur more often and are more severe when you take only one antituberculosis medication. B. Taking several antituberculosis medications will protect your liver from toxic effects. C. The organism that causes TB becomes resistant to antituberculosis medications when you only take one medication. D. People who have a severe form of TB need several antituberculosis medications, but those who have less severe TB need just one medication.

Correct Answer is C

Explanation

Choice A rationale

Adverse effects of antituberculosis medications do occur, but taking a single medication doesn't necessarily reduce their frequency or severity. Combination therapy aims to prevent resistance, not specifically to avoid side effects.

Choice B rationale

Multiple medications in TB treatment don't directly protect the liver from toxic effects. In fact, they may increase the risk of hepatotoxicity, but the benefit outweighs the risk due to reduced resistance.

Choice C rationale

The primary reason for using multiple antituberculosis medications is to prevent the development of drug resistance. TB bacteria can quickly become resistant when only one medication is used, leading to treatment failure.

Choice D rationale

TB treatment typically involves multiple drugs regardless of the severity of the disease to ensure effective eradication of the bacteria and prevent resistance.
