Your patient weighs 15 kg and is scheduled for to have an abdominal exploratory. You are instructed to provide 0.9% sodium chlor
kumpel [21]

Answer:

V_f=450ml/hr

Step-by-step explanation:

From the question we are told that:

Mass m=15kg

Amount of NaCl IV n=0.9\%

Rate R=30ml/kg/hr

Generally the equation for fluid rate be for your IV pump is mathematically given by

V_f=mR

Since

Rate is

30ml/kg/hr at 1kg patient Weight

Therefore

V_f=15*30

V_f=450ml/hr

Which expression can be used to find the surface area of the following square pyramid
andreyandreev [35.5K]

Answer:

36+15+15+15+15

Step-by-step explanation:

For the surface area we need to add up all the areas in the pyramid:

  • area of the base
  • area of the triangle sides (there are 4 triangles)

Area of the base:

the base is a square, and the area of a square is given by:

a_{base}=l^2

where l is the length of the side: l=6, thus:

a_{base}=(6)^2\\a_{base}=36

Area of the triangles:

one triangle has the area given by the formula:

a_{triangle}=\frac{b*h}{2}

where b is the base of the triangle: b=6

and h is the height of the triangle: h=5, thus we have the following:

a_{triangle}=\frac{6*5}{2} \\\\a_{triangle}=\frac{30}{2} \\\\a_{triangle}=15

the expression that represents the surface area of the pyramid is:

a_{base}+area_{triangle}+area_{triangle}+area_{triangle}+area_{triangle}

substituting our values:

36+15+15+15+15

which is option B
