A nurse is assisting with staff education about hand hygiene.
Which of the following instructions should the nurse include in the teaching?
Wash hands with soap and water for 20 seconds.
Wear sterile gloves when in contact with body fluids.
Use alcohol-based cleanser when hands are visibly soiled.
Artificial nails can be worn when performing direct client care.
The Correct Answer is A
Choice A rationale:
The nurse should include the instruction to wash hands with soap and water for 20 seconds in the teaching. This is a fundamental aspect of hand hygiene in healthcare settings. The rationale for this choice is that proper handwashing with soap and water for at least 20 seconds is the most effective way to remove dirt, debris, and transient microorganisms from the hands. It helps prevent the spread of infections, including those caused by viruses and bacteria.
Choice B rationale:
Wearing sterile gloves when in contact with body fluids is not directly related to hand hygiene education. While wearing gloves is an essential infection control practice, it is not a substitute for proper handwashing. Hand hygiene should be performed before donning gloves and after removing them.
Choice C rationale:
Using alcohol-based cleanser when hands are visibly soiled is not the best instruction for hand hygiene. Alcohol-based hand sanitizers are effective when hands are not visibly soiled. In cases of visible soiling, handwashing with soap and water is recommended to physically remove dirt and contaminants.
Choice D rationale:
Artificial nails should not be worn when performing direct client care as they can harbor microorganisms and make it challenging to clean the hands adequately. The use of artificial nails can increase the risk of transmitting infections to patients, which is why they should be discouraged in healthcare settings.

Correct Answer is B
Explanation
Choice A rationale:
Hydrogen peroxide. Hydrogen peroxide is not the recommended solution for disinfecting surfaces following a blood spill. While it can be used to clean wounds and may have some disinfectant properties, it is not as effective as bleach in destroying bloodborne pathogens.
Choice B rationale:
Bleach. Bleach is the appropriate choice for disinfecting surfaces contaminated with blood. A 10% bleach solution (1 part bleach to 9 parts water) is effective at killing bloodborne pathogens such as HIV and hepatitis B and C viruses. It should be used in healthcare settings to ensure proper disinfection after a blood spill.
Choice C rationale:
Isopropyl alcohol. Isopropyl alcohol is an effective disinfectant for some purposes, but it may not be as effective as bleach against bloodborne pathogens. It is commonly used for cleaning and disinfecting skin before medical procedures but is not the recommended choice for disinfecting surfaces following a blood spill.
Choice D rationale:
Chlorhexidine. Chlorhexidine is an antiseptic solution often used for skin disinfection before surgical procedures or invasive medical interventions. It is not typically used for disinfecting surfaces contaminated with blood.
Correct Answer is C
Explanation
Choice A rationale:
Relocating the sensor every 8 hours is not necessary when obtaining oxygen saturation readings unless there is a specific clinical reason to do so, such as skin irritation or poor perfusion at the sensor site. Frequent relocation can cause unnecessary disruption for the patient.
Choice B rationale:
Waiting 10 seconds after placing the probe before obtaining the oxygen saturation reading is not required. Modern pulse oximeters provide real-time readings, and there is no need to wait after placing the probe. The reading is usually stable within seconds.
Choice C rationale:
Choosing a finger with a capillary refill time of less than 2 seconds is an essential consideration when obtaining oxygen saturation readings. Capillary refill time is a measure of peripheral perfusion, and choosing a finger with good perfusion ensures accurate oxygen saturation measurements.
Choice D rationale:
Placing the sensor probe on the same extremity as an electronic blood pressure cuff is generally acceptable. However, it is crucial to ensure that the sensor does not interfere with the blood pressure cuff's function and that it is securely attached to the patient's finger for accurate readings.
