Extract:
Question 1 of 5
A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneously every 12 hr. The client's weight is 121 lb. Available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: 121 lb ÷ 2.2 = 55 kg; 55 kg × 1 mg/kg = 55 mg; 60 mg/0.6 mL = 100 mg/mL; 55 mg ÷ 100 mg/mL = 0.55 mL, rounded to 0.6 mL.
Question 2 of 5
A nurse is assessing a client who is taking an osmotic laxative. Which of the following findings should the nurse identify as an indication of fluid volume deficit?
