A nurse is instructing a client to take guaifenesin 1 tsp PO. How many mL should the nurse instruct the client to take? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

The nurse should instruct the client to take 5 mL of guaifenesin. Here’s the calculation for your reference: In the United States, 1 teaspoon (tsp) is approximately equivalent to 5 milliliters (mL). So, if the client is instructed to take 1 tsp of guaifenesin, this would be: Volume in mL=1tsp×5mL/tsp=5mL However, the question asks to round the answer to the nearest whole number. So, the nurse should instruct the client to take 5 mL of guaifenesin.
