The nurse explains that the immunizations against hepatitis B will:

Choice A rationale

Throwing the needle and syringe immediately into a garbage can, even if covered and lined, does not ensure proper disposal of biohazard materials. This practice increases the risk of contamination and injury.

Choice B rationale

Recapping the needle and placing it on the patient's table until leaving the room increases the risk of needle stick injuries and improper disposal, which is unsafe and against best practices for needle safety.

Choice C rationale

Breaking the needle from the syringe using the needle cover to prevent reuse does not eliminate the risk of needle stick injuries and may lead to improper disposal and handling of biohazard materials.

Choice D rationale

Never recapping the needle afterward is the safest practice to avoid the risk of needle stick injuries, as recapping is a common cause of such injuries. Proper disposal in a sharps container immediately after use is the recommended method.

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.
