A nurse is preparing to administer levothyroxine 50 mcg to a client. Available is levothyroxine 0.025 mg/tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

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.

A. Initiate an oxytocin IV infusion. Oxytocin may be used to augment labor, but it should not be started immediately without first assessing maternal and fetal well-being. Continuous monitoring is necessary before initiating any uterotonic agent.
B. Apply a fetal heart rate monitor. After rupture of membranes, assessing the fetal heart rate is critical to detect signs of umbilical cord prolapse or fetal distress. Continuous electronic fetal monitoring helps evaluate the baby's response to labor.
C. Initiate fundal massage. Fundal massage is performed after delivery of the placenta to help contract the uterus and reduce postpartum bleeding. It is not appropriate during active labor.
D. Insert an indwelling urinary catheter. A catheter may be placed if necessary during labor, especially before epidural anesthesia, but it is not the immediate priority following membrane rupture. Fetal monitoring takes precedence.
