The nurse encourages the 84-year-old patient who is recovering from a hip replacement to:

Keep the bed flat to aid in lung expansion.

Cough frequently to make up for the loss of cilia.

Encourage bed rest.

Restrict fluid to prevent pulmonary congestion.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Keeping the bed flat does not necessarily aid lung expansion and can sometimes increase the risk of aspiration in patients with compromised mobility or cognition.

Choice B rationale

Encouraging the patient to cough frequently helps clear secretions from the lungs, compensating for the diminished function of cilia in elderly patients.

Choice C rationale

Encouraging bed rest can lead to complications such as muscle atrophy, decreased lung capacity, and increased risk of pressure ulcers in elderly patients.

Choice D rationale

Restricting fluid intake to prevent pulmonary congestion is not generally recommended unless there is a specific medical condition requiring fluid restriction, as adequate hydration is vital for overall health.

Correct Answer is D

Explanation

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.

A. Vector. B. Fomite. C. Prions. D. Interferon.

Correct Answer is B

Explanation

Choice A rationale

Vectors are living organisms, such as mosquitoes, that transmit pathogens between humans or from animals to humans. An inanimate object like a glass is not a vector.

Choice B rationale

Fomites are inanimate objects that can carry and transmit pathogens, such as a glass, door handles, or medical instruments.

Choice C rationale

Prions are infectious proteins that cause neurodegenerative diseases, not inanimate objects that transmit infection.

Choice D rationale

Interferons are proteins produced by cells in response to viral infections and do not relate to the transmission of pathogens via inanimate objects. .
