The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth)

Answer and Explanation

The Correct Answer is ["5.6"]

Convert pounds to kg 1kg= 2.2 pounds 132pounds= 132/2.2=60kg

Desired dose per minute= 5 mcg/kg= 560=300mcg/min Desired dose per hour= 300mcg60mins= 18000mcg Available dose= 1600mg/500ml

1mg=1000mcg

Available dose = 1600000mcg/500ml Infusion rate:

1600000mcg=500ml 18000mcg=18000500/1600000

= 5.625 mL/hour

Rounded to the nearest tenth: 5.6 ml/hour

Correct Answer is A

Explanation

A. Low-fat dairy products: Dairy products such as milk, yogurt, and cheese are rich sources of calcium, which is essential for bone health and can help prevent osteoporosis, especially in older adults.

B. Fresh fruits and vegetables: While fruits and vegetables are important for overall health, they do not provide significant amounts of calcium, which is the primary nutrient needed for preventing osteoporosis.

C. Iron-rich meals: Iron-rich meals are important for preventing anemia but do not directly contribute to bone health and prevention of osteoporosis.

D. Water and herbal teas: While hydration is important for overall health, water and herbal teas do not provide significant amounts of calcium needed for bone health.

A. Flaky, peeling skin. B. Red bumps across chest. C. White coating on tongue. D. High, protracted fever.

Correct Answer is B

Explanation

A. Flaky, peeling skin (desquamation) occurs in later stages of scarlet fever, typically after the rash begins to fade. It is not an early sign of the disease.
B. A red, sandpaper-like rash that typically begins on the chest and spreads outward is one of the earliest indications of scarlet fever. This rash is caused by exotoxins produced by Streptococcus pyogenes and is a hallmark sign of the illness.
C. A white coating on the tongue, often followed by a characteristic “strawberry tongue,” develops later in the progression of scarlet fever rather than as an early symptom.
D. While fever is a common symptom of streptococcal infections, it is not the earliest indicator of scarlet fever. The rash usually appears within 12 to 48 hours of fever onset, making it a more specific early sign.
