A nurse explains to a client with hypertension that diastolic pressure is a measurement of what?

Choice A rationale:

Scabies is a skin infestation caused by the Sarcoptes scabiei mite. While it is contagious, it does not require the use of an N95 respirator mask. Standard precautions, including wearing gloves, are sufficient when caring for a client with scabies.

Choice B rationale:

Mycoplasmal pneumonia is a type of pneumonia caused by the bacteria Mycoplasma pneumoniae. It is typically spread through respiratory droplets and does not require the use of an N95 respirator mask. Standard precautions, including wearing a mask, are appropriate for this condition.

Choice C rationale:

Tuberculosis (TB) is a highly contagious bacterial infection caused by Mycobacterium tuberculosis. TB spreads through the air when an infected person coughs or sneezes. To prevent the inhalation of TB bacteria, healthcare workers should wear N95 respirator masks (or higher level respirators) when caring for clients with active TB disease.

Choice D rationale:

Scarlet fever is a bacterial illness that develops in some people who have strep throat. It is caused by group A Streptococcus bacteria and is typically treated with antibiotics. Scarlet fever does not require the use of an N95 respirator mask. Standard precautions, including wearing gloves and a mask, are appropriate when caring for a client with scarlet fever. Wearing an N95 respirator mask is crucial when caring for clients with airborne infectious diseases like tuberculosis. This type of mask is designed to filter out at least 95% of airborne particles, providing a high level of protection for healthcare workers.

Choice D rationale:

When preparing to open a sterile pack, the nurse must touch only the inner surface of the inner wrapper to maintain sterility. This is a fundamental principle of aseptic technique. Sterile items should be handled with care to prevent contamination. By touching only the inner surface of the inner wrapper, the nurse ensures that the contents of the pack remain sterile and safe for use in medical procedures. Any contact with the outer surface or other non-sterile items can compromise the sterility of the contents.

Choice A rationale:

Placing the sterile pack on a clean surface is a good practice but does not ensure the maintenance of sterility. Sterile items should be placed on a sterile surface or field to prevent contamination. Placing the pack on a clean surface may still expose it to potential contaminants, compromising its sterility.

Choice B rationale:

Turning the pack so that the first flap faces the nurse's body is incorrect. The first flap should be opened away from the nurse to avoid the risk of contamination. By opening the flap away from the nurse, any potential contaminants in the air are less likely to come into contact with the sterile contents.

Choice C rationale:

Opening the right-side flap first is not a standard practice for opening a sterile pack. The choice of which side to open first may vary based on individual preference or the design of the packaging. The key factor is to maintain the sterility of the contents by handling the pack appropriately, as mentioned in choice D.
