Complete the following sentence by using the list of options.
The nurse should wear an
The Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"C"}
Rationale for correct choices:
• N95 respirator: Mycobacterium tuberculosis is transmitted via airborne particles that remain suspended in the air. An N95 respirator is required to filter airborne droplet nuclei and protect the nurse from inhalation exposure. Standard surgical masks do not provide adequate airborne protection in confirmed TB cases.
• Gloves: As part of Standard Precautions, gloves should always be worn when there is a risk of contact with body fluids, such as sputum or contaminated surfaces in the client's room.
Rationale for incorrect choices:
• Surgical mask: A surgical mask protects against large respiratory droplets but does not filter airborne particles. TB requires airborne precautions, which exceed the level of protection provided by a standard mask. Surgical masks are more appropriate for droplet-based infections.
• Face shield: A face shield protects mucous membranes from splashes or sprays but does not filter inhaled air. TB does not spread via splashes, making this equipment unnecessary for routine airborne precautions. Respiratory protection remains the priority.

Correct Answer is B
Explanation
A. Hematuria: Hematuria is not a typical adverse effect of methylergonovine. This medication primarily affects uterine smooth muscle and vascular tone, so urinary complications are uncommon.
B. Elevated blood pressure: Methylergonovine is a potent vasoconstrictor, which can lead to hypertension. Monitoring blood pressure is essential because severe elevations can increase the risk of stroke or cardiac complications, especially in clients with preexisting hypertension.
C. Uterine relaxation: Methylergonovine promotes uterine contraction, not relaxation. Uterine relaxation would be contrary to the intended therapeutic effect of preventing or controlling postpartum hemorrhage.
D. Diarrhea: Gastrointestinal upset, including nausea, vomiting, or diarrhea, can occur but is less common and typically mild. Blood pressure changes are the primary adverse effect requiring close monitoring.
Correct Answer is D
Explanation
A. Have visitors remain at least 0.91 m (3 feet) away from the client: Varicella zoster is highly contagious and spreads through airborne droplets, so simply keeping visitors a short distance away is insufficient to prevent transmission. More stringent precautions are required.
B. Initiate contact precautions for the client: Contact precautions alone do not adequately prevent the airborne spread of varicella. Airborne precautions must be implemented in addition to standard and contact precautions to protect others.
C. Administer aspirin if the client develops a fever: Aspirin is contraindicated in children with varicella due to the risk of Reye’s syndrome. Alternative antipyretics, such as acetaminophen, should be used instead.
D. Assign the client to a negative pressure airflow room: Airborne precautions, including placement in a negative pressure room, are necessary to prevent the spread of varicella to other clients and healthcare staff. This intervention effectively contains airborne pathogens and is a standard infection control measure.
