The nurse recommends a good agent for disinfecting contaminated areas in the home is:

A 10% solution of chlorine bleach.

To soak in a solution of povidone iodine for 30 minutes and rinse with hot water.

A 12% solution of alcohol.

To cover the area with boiling water and let it air dry.

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is D

Explanation

Choice A rationale

While immune globulin can be given to non-immune individuals exposed to chickenpox, the baby already has some protection because the mother has naturally acquired immunity. Hence, giving immune globulin is not necessary in this case.

Choice B rationale

Although the infant has not been immunized against chickenpox, the baby still receives passive immunity through the mother's breast milk. The antibodies transferred via breastfeeding provide some level of protection to the baby.

Choice C rationale

The mother's immunity against chickenpox, acquired from a past infection, remains effective throughout her life. This immunity is transferred to the baby through the placenta during pregnancy and continues through breastfeeding, providing protection to the infant.

Choice D rationale

The mother’s naturally acquired immunity from her childhood infection provides antibodies against chickenpox that she passes on to the baby through the breast milk. This passive immunity helps protect the baby from the infection.

A. Scabies. B. Tuberculosis. C. Scarlet fever. D. Mycoplasmal pneumonia.

Correct Answer is B

Explanation

Choice A rationale

Scabies is a parasitic skin infestation caused by mites. It spreads through direct skin-to-skin contact and does not require an N95 respirator. Standard precautions and contact isolation are usually sufficient.

Choice B rationale

Tuberculosis is an airborne infectious disease. An N95 respirator mask is necessary to protect against inhaling airborne droplets that may contain the bacteria, especially in healthcare settings.

Choice C rationale

Scarlet fever is a bacterial infection caused by group A Streptococcus. It spreads through respiratory droplets, but standard surgical masks are usually adequate. An N95 respirator is not required.

Choice D rationale

Mycoplasmal pneumonia is a type of bacterial pneumonia transmitted through respiratory droplets. While it can be contagious, an N95 respirator is generally not necessary unless in specific aerosol-generating procedures. Standard precautions are usually sufficient. .
