A nurse is preparing to administer ceftriaxone 1 g intermittent IV bolus to a client over 30 min. Available is ceftriaxone 1 g in 100 mL of dextrose 5% in water. The nurse should set the pump to deliver how many mL per hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Hyperthyroidism. This condition is not a contraindication to the use of combination oral contraceptives. Women with hyperthyroidism can generally use hormonal contraceptives safely under medical supervision.
B. Hypocalcemia. Low calcium levels are not linked to increased risk with combination oral contraceptives and do not contraindicate their use.
C. Thrombophlebitis. This condition involves inflammation and clot formation in the veins, and is a major contraindication to combination oral contraceptives. These medications increase the risk of blood clots, making them unsafe for clients with current or prior thromboembolic disorders.
D. Diverticulosis. This gastrointestinal condition is not affected by hormone levels and is not a contraindication to combination oral contraceptive use.

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.
