The situation in which protective eyewear is required is:
Suctioning a tracheotomy.
Changing a baby’s diaper.
Applying a dressing on the leg.
Gathering the linens off a contaminated bed.
The Correct Answer is A
Choice A rationale
Suctioning a tracheotomy involves contact with respiratory secretions which can be infectious. Protective eyewear is necessary to prevent exposure to potentially infectious fluids.
Choice B rationale
Changing a baby’s diaper involves exposure to feces and urine, but does not usually require protective eyewear as splashing is not common.
Choice C rationale
Applying a dressing on the leg generally does not involve significant risk of splashes or sprays to the eyes, making protective eyewear unnecessary.
Choice D rationale
Gathering linens off a contaminated bed poses some risk of contamination, but typically does not involve splashes or sprays that would necessitate protective eyewear.

Correct Answer is D
Explanation
Choice A rationale
Organisms that cause the infection refer to the pathogens such as bacteria, viruses, or fungi. In the context of pneumococcal pneumonia, the organism is Streptococcus pneumoniae. The lungs do not serve as the organisms; they are the site of infection.
Choice B rationale
Transmission of the disease involves the spread of pathogens from one individual to another. Pneumococcal pneumonia is transmitted via respiratory droplets, not the lungs serving as the transmission medium.
Choice C rationale
Mode of transfer refers to the mechanisms by which an infection spreads, such as direct contact, airborne, or vector-borne. The lungs are not a mode of transfer; they are the site of infection.
Choice D rationale
Reservoirs are places where pathogens live, grow, and multiply. In the case of pneumococcal pneumonia, the lungs act as a reservoir where the bacteria can grow and cause infection.
Correct Answer is A
Explanation
Choice A rationale
A 10% solution of chlorine bleach is an effective disinfectant for contaminated areas in the home. Chlorine bleach has broad-spectrum antimicrobial properties, making it suitable for killing various pathogens, including bacteria and viruses.
Choice B rationale
Soaking in a solution of povidone iodine for 30 minutes and rinsing with hot water is not practical for home disinfection. While povidone iodine is effective as a disinfectant, it is typically used for medical purposes and not for cleaning household surfaces.
Choice C rationale
A 12% solution of alcohol is not as effective as a 10% solution of chlorine bleach for disinfecting contaminated areas in the home. Alcohol concentrations above 70% are generally more effective for disinfection purposes.
Choice D rationale
Covering the area with boiling water and letting it air dry is not a reliable method for disinfecting contaminated areas. Boiling water may not effectively kill all pathogens, and this method lacks the broad-spectrum efficacy of chemical disinfectants.
