Patients who have diabetes mellitus should have dilated eye exams at which of the following frequencies?

A. Wrapping hinged instruments in the open, unlocked position: Hinged instruments should be wrapped in the open, unlocked position to ensure that steam can penetrate all surfaces for effective sterilization.
B. Allowing the temperature of the autoclave to reach 200° F before timing: The autoclave should reach the required temperature (typically 250°F or 121°C) for the appropriate amount of time for sterilization, not 200°F.
C. Using a ballpoint pen to label contents: It is not advisable to use a ballpoint pen for labeling sterilized items because ink might not withstand the autoclave's high temperatures. Permanent markers or labels that can endure high temperatures should be used.
D. Stacking wrapped packages tightly into the autoclave: Items should be arranged in a way that allows steam to circulate freely, so tightly stacking packages can hinder proper sterilization.

A. Exposure to a mosquito bite: Hepatitis B is not transmitted through mosquito bites. It is primarily transmitted through contact with infected body fluids, particularly blood.

B. Consumption of raw shellfish: Hepatitis A, not Hepatitis B, can be contracted through the consumption of contaminated food or water, including raw shellfish.

C. Blood splashes to the mucous membranes: Hepatitis B can be transmitted through exposure to infected blood or body fluids, including splashes to mucous membranes (e.g., eyes, mouth).

D. Direct skin contact with a patient who is infected: Hepatitis B is not transmitted through casual skin contact. It requires contact with infected body fluids.
