Dose Calculation Questions

Question 1: 6854 mcg = g

• Conversion required: micrograms (mcg) to grams (g).
• 1 g = 1,000,000 mcg.
• Calculation: $6854 mcg imes \frac{1 g}{1,000,000 mcg} = 0.006854 g$.

Question 2: 52 lbs = kg

• Conversion required: pounds (lbs) to kilograms (kg).
• 1 kg ≈ 2.20462 lbs.
• Calculation: $52 lbs imes \frac{1 kg}{2.20462 lbs} ext{ = 23.6 kg (rounded to the nearest tenth)}$.

Question 3: 45 tsp = L

• Conversion required: teaspoons (tsp) to liters (L).
• 1 tsp ≈ 4.92892 mL, thus 1 L = 1000 mL.
• Calculation: $45 tsp imes 4.92892 mL/tsp imes \frac{1 L}{1000 mL} ext{ = 0.222 L}$.

Question 4: Carprofen Prescription for Dogs

• Dosage: 50 mg of carprofen daily for two weeks (14 days).

• Confirm the amount of chewables (assumed as a specific mg per chewable).

Question 5: Hydroxyzine Dosage

• Weight of Dog: 50 lbs.
• Dose: 2.2 mg/kg, to be administered BID (twice a day).
• Kilogram conversion: $50 lbs imes \frac{1 kg}{2.20462 lbs} ext{ = 22.7 kg}$.
• Total Dose: $2.2 mg/kg imes 22.7 kg ext{ = 49.94 mg per day (rounded to 50 mg)}$.
• Daily Requirement: 50 mg per day × 2 = 100 mg total per day.
• Number of tablets per prescription based on tablet mg (assumed).

Question 6: Sucralfate for a Foal 220 lbs

• Weight of Foal: 220 lbs.
• Dosage: 20 mg/kg.
• Kilogram conversion: $220 lbs imes \frac{1 kg}{2.20462 lbs} ext{ = 99.78 kg}$.
• Total Dose: $20 mg/kg imes 99.78 kg ext{ = 1995.6 mg}$.
• Volume of Suspension: Given concentration is 1 g per 10 mL (1 g = 1000 mg).
• Calculation of mL required: $1995.6 mg imes \frac{10 mL}{1000 mg} ext{ = 19.96 mL (rounded to 20 mL)}$.

Question 7: Azithromycin for a 34 lbs Dog

• Weight of Dog: 34 lbs.
• Dosage: 8 mg/kg SID.
• Calculation of kg: $34 lbs imes \frac{1 kg}{2.20462 lbs} ext{ = 15.42 kg}$.
• Total Dose: $8 mg/kg imes 15.42 kg ext{ = 123.36 mg}$.
• Volume Calculation from Suspension: Each 5 mL contains 200 mg of azithromycin.
• Required volume: $123.36 mg imes \frac{5 mL}{200 mg} ext{ = 3.09 mL (rounded to 3.1 mL)}$.

Question 8: Calcium Gluconate for a 1000 lbs Horse

• Dosage Administered: 500 mL of calcium gluconate.
• Concentration needed for calcium grams calculation (provided concentration unspecified).
• Grams received calculation: (Assumed concentration needed).

Question 9: Prepare 25 mL of 8% Formaldehyde

• Required Volume for Preparation: Desired concentrated solution's percentage requires calculation from a 20% solution.
• Formula: C1V1 = C2V2, where C1 = 20%, C2 = 8%, V2 = 25 mL.
• Solving: 20rac{ ext{{}}}{100}=x imes 25 ext{ mL}$\Rightarrow V1=rac{8 ext{ mL}}{20 ext{ mL}}=20 ext{ mL}.

Question 10: Morphine for a 15 lbs Dog

• Dosage: 1.8 mg/kg IM every 4 hours.
• Weight Conversion: $15 lbs = 6.81 kg$.
• Total Dose: $1.8 mg/kg imes 6.81 kg ext{ = 12.24 mg per dose}$.
• Calculated Volume: For morphine concentration (10 mg/mL): $12.24 mg imes \frac{1 mL}{10 mg} ext{ = 1.22 mL (rounded to 1.2 mL)}$.

Question 11: Triamcinolone for 1348 lbs Horse

• Dosage Required: 0.15 mg/kg IM.
• Weight Conversion: $1348 lbs = 611.93 kg$.
• Total Dose Calculation: $0.15 mg/kg imes 611.93 kg ext{ = 91.79 mg}$.
• Volume Required: Based on provided concentration.

Question 12: Cyanocobalamin for Dog weighing 79 lbs

• Dosage Needed: 0.025 mg/kg/week.
• Weight Calculation: $79 lbs o 35.8 kg$.
• Total Weekly Dose: $0.025 mg/kg imes 35.8 kg ext{ = 0.895 mg/week}$.
• Volume based on concentration: 1,000 mcg/mL.
