A nurse is teaching a class about infection control to a group of nurses. The nurse should identify which of the following diseases as requiring the implementation of droplet precautions?
Rubeola
Varicella
Tuberculosis
Pertussis
The Correct Answer is D
A. Rubeola (measles). Rubeola is transmitted through airborne particles and requires airborne precautions, including the use of an N95 respirator and placement in a negative pressure room. Droplet precautions would not provide sufficient protection due to the small particle size and long-range transmission.
B. Varicella (chickenpox). Varicella requires both airborne and contact precautions because it spreads via airborne respiratory droplets and direct contact with lesions. A client with varicella must be isolated in a negative pressure room and healthcare workers should use full PPE.
C. Tuberculosis. Tuberculosis is caused by Mycobacterium tuberculosis and is spread through airborne droplet nuclei, which remain suspended in the air for extended periods. It requires airborne precautions, including an N95 respirator and isolation in a specialized room.
D. Pertussis (whooping cough). Pertussis is a highly contagious bacterial infection that spreads through large respiratory droplets during coughing or sneezing. Droplet precautions are required, which include wearing a surgical mask when within 3 feet of the client and practicing proper hand hygiene to prevent transmission.

Correct Answer is C
Explanation
A. Provide frequent stimulation for the newborn. Excessive stimulation can worsen symptoms in newborns with neonatal abstinence syndrome (NAS), including irritability, tremors, and difficulty sleeping. These infants need a calm, low-stimulation environment to reduce neurologic stress.
B. Encourage frequent eye contact with the newborn during feedings. While bonding is important, prolonged or forced eye contact can overstimulate a newborn with NAS. These infants often have difficulty regulating sensory input and may become more irritable with excessive interaction.
C. Decrease the lighting levels in the nursery. A dim, quiet environment helps soothe infants experiencing NAS. Reducing lighting can minimize sensory overload, promote rest, and support neurologic regulation during withdrawal.
D. Wrap the newborn loosely in a blanket. Loose wrapping does not provide the security and containment that helps calm an overstimulated infant. Instead, swaddling the newborn snugly can reduce tremors, promote sleep, and offer comfort during withdrawal symptoms.
Correct Answer is D,A,B,C
Explanation
D. Transport the client to another area of the nursing unit. The first priority is rescue ensuring the client’s safety by removing them from the immediate area of danger, which is consistent with the "RACE" fire safety protocol (Rescue, Alarm, Contain, Extinguish).
A. Activate the facility's fire alarm system. Once the client is safe, the next step is to activate the fire alarm to notify other staff and initiate emergency protocols throughout the facility.
B. Close all nearby windows and doors. Containing the fire by closing doors and windows limits the spread of smoke and flames, buying time for response teams to arrive and control the situation.
C. Use the unit's fire extinguisher to attempt to put out the fire. If it is safe and the fire is small and manageable, the final step is to extinguish the fire using a fire extinguisher, following appropriate safety procedures.
