Question

question: 22 of 25
a nurse is caring for a client who has a pulmonary embolism and has a new prescription for enoxaparin 1.5mg/kg/dose subcutaneous every 12 hr. the client weighs 245 lbs. how many mg should the nurse administer per dose? (round the answer to the nearest whole number. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Convert pounds to kilograms

We know that \(1\space kg = 2.2\space lbs\). So, if the client weighs \(245\space lbs\), then the weight in kilograms \(x\) is given by \(x=\frac{245}{2.2}\space kg\).
$$x=\frac{245}{2.2}\approx111.36\space kg$$

Step2: Calculate the dose

The dose is \(1.5\space mg/kg/dose\). For a weight of \(x = 111.36\space kg\), the dose \(y\) is \(y=1.5\times x\).
Substitute \(x = 111.36\) into the formula: \(y = 1.5\times111.36\)
$$y=1.5\times111.36 = 167.04\space mg$$

Step3: Round the result

Rounding \(167.04\) to the nearest whole number gives \(167\space mg\).

Answer:

$167$
