The nurse uses the Standard Precautions, as outlined by the Centers for Disease Control and Prevention (CDC), when:
Caring for patients who have wounds draining body fluids.
Preventing transmission of respiratory and wound infections.
Caring for all patients.
There is a suspicion of or risk of infection.
The Correct Answer is C
Choice A rationale
While it is true that Standard Precautions apply to patients with draining wounds, these precautions are not limited to such scenarios. They are a broader set of practices.
Choice B rationale
Standard Precautions do help prevent the transmission of respiratory and wound infections, but their application is universal, not limited to these conditions.
Choice C rationale
Standard Precautions are designed to be used when caring for all patients, regardless of their diagnosis or infection status, to prevent the spread of infections.
Choice D rationale
Standard Precautions are used routinely with all patients, not only when there is a suspicion or risk of infection. This universal approach helps ensure a high level of infection control.

Correct Answer is D
Explanation
Choice A rationale
Disinfectants are not intended for use on the patient's body. Using them around the eyes or mouth can cause irritation or harm, as they are designed to kill or inhibit the growth of microorganisms on inanimate objects.
Choice B rationale
It is important to thoroughly clean and rinse all soap off equipment before disinfecting, as organic matter and soap residues can interfere with the disinfectant's effectiveness. Proper cleaning removes debris that can protect microorganisms from the disinfectant.
Choice C rationale
Disinfectants cannot sterilize instruments as sterilization refers to the complete elimination of all forms of microbial life, including spores. Bacteriostatic disinfectants only inhibit bacterial growth and do not achieve sterilization.
Choice D rationale
Removing organic matter prior to disinfecting is crucial because organic material can protect microorganisms from the disinfectant, reducing its effectiveness. Proper cleaning ensures that the disinfectant can directly contact and eliminate the microorganisms.
Correct Answer is A
Explanation
Choice A rationale
Creutzfeldt-Jakob disease is caused by prions, which are misfolded proteins that can induce normal proteins in the brain to also misfold. These prions are highly resistant to conventional methods of deactivation and pose a significant infection control challenge.
Choice B rationale
Fungi can cause a variety of infections, but they are not responsible for Creutzfeldt-Jakob disease. Fungal infections typically affect the skin, lungs, or systemic organs.
Choice C rationale
Protozoa are single-celled organisms that can cause diseases such as malaria. They are not related to the prions that cause Creutzfeldt-Jakob disease.
Choice D rationale
Viruses cause a range of diseases, including influenza and HIV, but they are distinct from prions. Prions lack genetic material and reproduce by corrupting normal proteins, which is different from viral replication mechanisms. .
