The nurse cautions that a person in the incubation period of an infection:

Will always exhibit symptoms within 48 hours.

Will seek medical attention for the relief of symptoms.

Can transmit the disease although he or she does not feel ill.

Has identifiable signs of a specific illness.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Symptoms of an infection may not always appear within 48 hours. The incubation period varies depending on the infectious agent and can range from hours to weeks, during which the person may not show any signs of illness.

Choice B rationale

A person in the incubation period does not exhibit symptoms and, therefore, is unlikely to seek medical attention for symptom relief. Medical attention is usually sought when symptoms manifest and impact the person's well-being.

Choice C rationale

During the incubation period, the person can transmit the disease to others even if they do not feel ill. This period involves the replication of the pathogen within the host, and the person may be contagious without knowing it.

Choice D rationale

Identifiable signs of a specific illness appear during the symptomatic phase, not during the incubation period. The incubation period is the time between exposure to the pathogen and the appearance of initial symptoms.

Correct Answer is B

Explanation

Choice A rationale

Breaking needles in half before disposal is dangerous and not recommended. It increases the risk of needlestick injuries and exposure to bloodborne pathogens.

Choice B rationale

Not recapping needles, especially after drawing arterial blood gas (ABG) specimens, is a recommended practice to prevent needlestick injuries. This reduces the risk of accidental puncture during the recapping process.

Choice C rationale

Recapping needles and placing them in a wastebasket is unsafe and increases the risk of needlestick injuries and improper disposal of medical waste, which can expose others to bloodborne pathogens.

Choice D rationale

Placing uncapped needles directly into a puncture-proof container after use is a safe practice, but the question specifically asks about preventing needlestick injuries during the handling of ABG specimens, where recapping should be avoided.

A. Dressings. B. Surgical instruments. C. Floors and walls. D. Heat sensitive items.

Correct Answer is D

Explanation

Choice A rationale

Dressings are typically sterilized using steam or other standard methods, not ethylene oxide gas, which is reserved for materials that are sensitive to heat and moisture.

Choice B rationale

Surgical instruments are commonly sterilized using steam autoclaving, which is highly effective and efficient.

Choice C rationale

Floors and walls do not require sterilization with ethylene oxide gas; standard cleaning and disinfection methods are sufficient.

Choice D rationale

Heat-sensitive items require ethylene oxide gas sterilization because it is effective at low temperatures without damaging delicate materials.
