Loc weighs 14 pounds. The HCP prescribes an IV infusion of 5% dextrose in 1/4 normal saline to be infused at 8mL/kg/hr. How many

IRINA_888 [86]

Answer:

50.80 mL/hr

Step-by-step explanation:

The prescription is using kg for the mass unit while the weight use pounds. We have to change the weight unit into kilograms to calculate the dose of the IV infusion. The type of solution should not have any influence on the calculation.

If one kilogram equal to 0.0.453592 pounds, the calculation will be:

14 pounds * (0.0.453592 kg/ pounds) * 8mL/kg/hr=

6.35 kg * 8mL/kg/hr= 50.80 mL/hr

Como Determinar a equação da reta que passa pelos pontos A(-1, -2) e B(5,2)

Komok [63]

Answer:

A equação da reta é dada por: $y = \frac{2}{3}x - \frac{4}{3}$

Step-by-step explanation:

Equação de uma reta:

A equação de uma reta tem o seguinte formato:

$y = ax + b$

Em que a é o coeficiente angular e b é o coeficiente linear.

Coeficiente angular:

Com posse de dois pontos, o coeficiente angular é dado pela mudança em y dividida pela mudança em x.

A(-1, -2) e B(5,2)

Mudança em y: 2 - (-2) = 2 + 2 = 4

Mudança em x: 5 - (-1) = 5 + 1 = 6

Coeficiente angular: $m = \frac{4}{6} = \frac{2}{3}$

Então:

$y = \frac{2}{3}x + b$

Coeficiente linear:

Substituindo um ponto na equação, encontra-se o coeficiente linear.

B(5,2)

Quando $x = 5, y = 2$ . Então:

$y = \frac{2}{3}x + b$

$2 = \frac{2}{3}5 + b$

$b = 2 - \frac{10}{3} = \frac{6}{3} - \frac{10}{3} = -\frac{4}{3}$

Então:

$y = \frac{2}{3}x - \frac{4}{3}$
