Correct Answer: D

Rationale: Infections that require airborne precautions necessitate the use of an N95 respirator, a type of mask that filters particles that are 5 micrograms or smaller. Illnesses that require airborne precautions include Measles, Varicella, Severe Acute Respiratory Syndrome (SARS), and tuberculosis. Measles is a highly contagious airborne disease caused by a virus. It can spread through respiratory droplets when an infected person coughs or sneezes. Wearing an N95 respirator helps prevent the nurse from inhaling these infectious particles. Human immunodeficiency virus, Clostridium difficile enterocolitis, and Vancomycin-resistant enterococcus do not require the use of an N95 respirator as they are not transmitted through the air but have other modes of transmission.

Correct Answer: B

Rationale: MSDS sheets, also known as Materials Safety Data Sheets, are essential documents that provide detailed information about chemicals used in the workplace. They are required by OSHA to be easily accessible to all employees to ensure they have the necessary information to handle chemicals safely. MSDS sheets do not contain ordering information for equipment in the office (Choice A) or serve as a treatment guide for injured patients (Choice C). Therefore, the correct answer is that MSDS sheets are required by OSHA to be accessible to all employees of the office.

Correct Answer: C

Rationale: When caring for a client requiring droplet precautions, it is essential for the nurse to wear a mask when within 3 feet of the client. This practice helps prevent the transmission of droplet particles that may be produced when the client coughs or sneezes. Assigning the client to a negative-pressure room is not typically necessary for droplet precautions unless specifically indicated for airborne precautions. Using sterilized equipment when sharing between clients with pertussis is important for infection control but does not directly relate to droplet precautions. Therefore, the correct action to uphold droplet precautions in this scenario is to wear a mask when coming within close proximity to the client.

Correct Answer: C

Rationale: The correct sequence for removing personal protective equipment is crucial to prevent contamination. When exiting a surgical or aseptic situation, the proper sequence is to first remove gloves, followed by the gown, mask, and finally shoe covers. This order ensures that potentially contaminated items are removed first, minimizing the risk of exposure. Choice A, 'Remove gown, gloves, shoe covers, mask,' is incorrect as gloves should be removed before the gown. Choice B, 'Remove mask, gloves, gown, shoe covers,' is incorrect as gloves should be removed first. Choice D, 'Remove shoe covers, mask, gloves, gown,' is incorrect as gloves should be the first item removed to prevent contamination.

Correct Answer: C

Rationale: The correct answer is gloves. When attending a high-risk delivery and handling a newborn immediately after birth, the minimum personal protective equipment required for a nurse includes gloves. This is essential to protect the nurse from potential exposure to the mother's blood or body fluids that may be present on the newborn's skin. Choices A, B, and D include additional protective equipment that is not necessary for this specific scenario. Wearing gloves is crucial for infection control and to prevent the transmission of pathogens.
