An adolescent patient is to receive 50 mL of Cefazolin IV over 40 minutes. With a tubing drop factor of 20 gtt/mL, how many drops per minute (gtt/min) should be given?

A. “We will keep our household hot water heater at 130 degrees.”

The recommended setting for a hot water heater is typically 120 degrees Fahrenheit to prevent scalds. Setting it at 130 degrees may still pose a risk of burns to young children.

B. “We will place poisonous substances in a high cupboard.”

Placing poisonous substances out of reach in a high cupboard is a safety measure to prevent children from accessing potentially harmful substances.

C. “We will place a gate at the top and bottom of stairways.”

Using safety gates at the top and bottom of stairways is an effective way to prevent young children from falling down stairs.

D. “We will put plastic fillers in all electrical plugs.”

Placing plastic fillers in electrical plugs helps prevent children from inserting objects into outlets, reducing the risk of electric shock.

E. “We will turn handles of pans on the stove toward the back of the stove.”

Turning handles of pans on the stove toward the back is a safety measure to prevent young children from reaching up and pulling hot items off the stove.

A. Dark red, macular lesions, and very pruritic:

Varicella lesions are typically pink or red and start as macules (flat, red spots) that develop into papules (raised bumps) and then vesicles (fluid-filled blisters). Dark red macular lesions are not commonly associated with varicella.

B. Various stages of lesions present at the same time, appear in successive crops, and very pruritic:

The presence of various stages of lesions (papules, vesicles, crusts) simultaneously, occurring in successive crops, and being intensely itchy are typical features of varicella.

C. Yellowish, scaly patches present on the scalp:

Yellowish, scaly patches on the scalp are not typical of varicella. This description is more indicative of conditions like seborrheic dermatitis rather than the rash associated with chickenpox.

D. A pink maculopapular rash starts at the hairline and spreads down the body.

Varicella rash usually begins as pink or red spots that develop into small, itchy, fluid-filled blisters (vesicles). These vesicles can then progress to form crusts and scabs. The rash often starts on the face, scalp, or trunk and then spreads to other parts of the body, gradually covering the entire body.
