A patient is prescribed 0.5 mg of a drug per kg of body weight. If the patient weighs 80 kg, what is the total dose required?

A clinic sees 240 patients in a 6-day work week. If the number of patients seen each day increases by 10%, how many patients will be seen per day after the increase?

Answer: 44

The original daily rate is 240/6 = 40 patients, and 10% of 40 is 4, so the new daily rate is 44.

A solution contains 250 mL of saline at a concentration of 0.9%. How many grams of salt are in the solution?

0.9% of 250 mL = 0.009 × 250 = 2.25 g of salt.

A hospital pharmacy fills 15 prescriptions per hour. At this rate, how many prescriptions will be filled in a 7.5-hour shift?

A clinical trial has 3 phases. Phase 1 has 20 participants, Phase 2 has 5 times as many, and Phase 3 has twice as many as Phase 2. What is the total number of participants?

Answer: 260

Phase 1 = 20, Phase 2 = 100, Phase 3 = 200; total = 20 + 100 + 200 = 320.

If a doctor earns $180,000 per year and saves 15% of their income, how much do they save per month?
