Diagnostic Test 3 Practice Test

A 68-year-old with community-acquired pneumonia is scheduled to receive ceftriaxone diluted in 250 mL of 0.9% sodium chloride. Per protocol, the dose should infuse evenly over 2 hours and 30 minutes using a smart pump that requires a rate in mL per hour. No other piggyback medications will run at the same time. The nurse requests a double-check of the correct pump setting for this infusion.

Which of the following represents the correct infusion rate (mL/hr)?

A 59-year-old woman (height 5 ft 4 in; weight 95 kg) is on CRRT for septic AKI and will receive TPN. Labs: K 3.6 mEq/L, phosphate 2.7 mg/dL, Mg 1.7 mg/dL, SCr 1.9 mg/dL on CRRT. The ICU team requests: use adjusted body weight for energy and protein (25 kcal/kg/day and 2.2 g/kg/day); electrolytes using adjusted body weight: sodium 2 mEq/kg/day and potassium 1.5 mEq/kg/day; magnesium 20 mEq/day; phosphate 45 mmol/day. Calculate daily requirements. (Female IBW = 45.5 kg + 2.3 kg per inch over 5 ft; AdjBW = IBW + 0.4 × ABW − IBW.)

Which of the following represents the correct daily calorie/protein/electrolyte requirement for this patient?
