A nurse is caring for a group of clients on an infectious disease unit.
The nurse should wear an N95 respirator mask when caring for a client who has which of the following disorders?
Scabies.
Mycoplasmal pneumonia.
Tuberculosis.
Scarlet fever.
The Correct Answer is C
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.

Correct Answer is A
Explanation
Choice A rationale:
Proper hand-washing technique involves washing hands for at least 20 seconds. This duration ensures thorough cleansing and removal of germs, dirt, and contaminants from the hands. Washing for a shorter time, such as 10 seconds (Choice B), may not effectively eliminate all harmful microorganisms, increasing the risk of infections and transmission of diseases.
Choice B rationale:
Washing hands for only 10 seconds is insufficient to achieve the necessary level of cleanliness. It is essential to follow recommended guidelines to prevent the spread of infections in healthcare settings and other environments where hygiene is crucial.
Choice C rationale:
Washing hands for 45 seconds (Choice C) is longer than the recommended duration and might not be practical, especially in busy healthcare settings. While thorough hand hygiene is essential, excessively long washing times could lead to reduced compliance among healthcare workers, potentially compromising patient safety.
Choice D rationale:
Proper hand-washing technique involves scrubbing hands for at least 20 seconds, making Choice D incorrect. Following the recommended guidelines is crucial to maintaining a safe and hygienic healthcare environment.
Correct Answer is ["473"]
Explanation
The correct answer is choice: 473.
To convert 4 ounces to milliliters (mL), the following steps can be taken:
Understand the Conversion Factor: 1 fluid ounce (oz) is approximately 29.57 mL. Therefore, 4 oz can be converted to mL using the following calculation: 4 × 29.57 = 118.28
4oz × 29.57mL/oz = 118.28mL.
Convert Cups to Ounces: 1 cup is equal to 8 fluid ounces.
Therefore, 1 cup is 8 × 29.57= 236.56
8oz × 29.57mL/oz = 236.56mL.
So, 1 cup is equal to 236.56 mL. The correct answer is 473 mL (2 cups)
