The nurse is assessing the client's vital signs and is aware that which assessment data requires immediate attention?

The correct answer is C. Tuberculosis.

Choice A rationale:

Scabies is a skin infestation caused by mites, and it does not require airborne precautions. Standard precautions, such as gloves and hand hygiene, are sufficient.

Choice B rationale:

Mycoplasmal pneumonia is typically spread through droplets, and a regular surgical mask is usually adequate for protection.

Choice C rationale:

Tuberculosis (TB) is an airborne disease, and healthcare workers need to wear an N95 respirator to protect themselves from inhaling the bacteria.

Choice D rationale:

Scarlet fever is spread through respiratory droplets, but it does not require airborne precautions. Standard precautions are usually enough.

Choice A rationale:

A pulse rating of 2+ is not considered an expected finding. It indicates a weaker pulse, which requires further assessment.

Choice B rationale:

A pulse rated as 2+ means the pulse is full volume and bounding. In clinical practice, a 2+ pulse is considered normal and signifies a pulse that is easily palpable and has a normal strength. This is an essential finding for the nurse to understand because it reflects the circulatory status of the client. A 2+ pulse suggests adequate perfusion and a healthy heart pumping blood effectively.

Choice C rationale:

A pulse rating of increased and strong corresponds to a higher numeric value on the scale, indicating a stronger pulse. A 2+ pulse is not categorized as increased but is rather a moderate strength pulse.

Choice D rationale:

A pulse rating of 2+ does not suggest an absent pulse. An absent pulse would mean that no pulse can be felt, which is a critical situation requiring immediate medical attention.
