a. 5 ml c. 10 ml
b. 7.5 ml d. 15 ml

Explanation:

Step1: Convertir litros a mililitros

Sabemos que \(1\ L = 1000\ mL\). Entonces, para convertir \(2.5\ L\) a \(mL\), multiplicamos \(2.5\times1000\).

$$2.5\times1000 = 2500$$

Step2: Convertir miligramos a gramos

Como \(1\ g= 1000\ mg\), para convertir \(5000\ mg\) a \(g\), dividimos \(5000\div1000\).

$$5000\div1000 = 5$$

Step3: Convertir onzas a mililitros

Sabemos que \(1\ onza = 29.5735\ mL\) (aproximadamente \(30\ mL\)). Entonces, para \(12\ onzas\), multiplicamos \(12\times30\).

$$12\times30 = 360$$

Step4: Convertir libras a kilogramos

Como \(1\ lb = 0.453592\ kg\), para \(150\ lb\), multiplicamos \(150\times0.453592\approx68.04\approx68.1\)

Step5: Convertir grados Fahrenheit a grados Celsius

La fórmula es \(C=\frac{5}{9}(F - 32)\). Sustituyendo \(F = 98.6\):

$$C=\frac{5}{9}(98.6 - 32)=\frac{5}{9}\times66.6 = 37$$

Step6: Calcular la dosis de furosemida

Si tenemos \(40\ mg\) ordenados y la concentración es \(10\ mg/mL\), usamos la fórmula \(V=\frac{D}{C}\) (donde \(V\) es el volumen, \(D\) la dosis y \(C\) la concentración). Entonces \(V=\frac{40}{10}=4\)

Step7: Calcular la dosis de amoxicilina

Si la concentración es \(250\ mg/5\ mL\) (es decir, \(50\ mg/mL\)) y la dosis ordenada es \(500\ mg\). Usando \(V=\frac{D}{C}\), \(V=\frac{500}{50}=10\)

Answer:

1. B. \(2500\ mL\)
2. B. \(5\ g\)
3. C. \(360\ mL\)
4. C. \(68.1\ kg\)
5. B. \(37^{\circ}C\)
6. C. \(4\ mL\)
7. C. \(10\ mL\)
