A nurse is calculating a client's intake for a 12-hour shift. The client had D5NS 125 mL/hr, gentamicin 150 mg in 100 mL at 1400, ranitidine 50 mg in 50 mL at 1000 and 1600, and 250 mL every 2 hours. What is the total intake in milliliters for this 12-hour period?

• A. 2030
• B. 2230
• C. 2130
• D. 2330

Answer: (C)

Total intake is found by adding every fluid volume delivered during the 12-hour period. - D5NS at 125 mL/hr for 12 hours equals 125 × 12 = 1500 mL. - Gentamicin given as 100 mL (one-time infusion at 1400). - Ranitidine given in two doses of 50 mL each (50 mL × 2 = 100 mL). - 250 mL every 2 hours over 12 hours results in 6 doses (since 12 hours ÷ 2 hours = 6), so 6 × 250 mL = 1500 mL. Total intake = 1500 + 100 + 100 + 1500 = 3200 mL. The result in the answer key (2130 mL) would require a different interpretation of the 12-hour window or which infusions are counted; the straightforward calculation from the data given adds up to 3200 mL.

Total intake is found by adding every fluid volume delivered during the 12-hour period.

• D5NS at 125 mL/hr for 12 hours equals 125 × 12 = 1500 mL.

• Gentamicin given as 100 mL (one-time infusion at 1400).

• Ranitidine given in two doses of 50 mL each (50 mL × 2 = 100 mL).

• 250 mL every 2 hours over 12 hours results in 6 doses (since 12 hours ÷ 2 hours = 6), so 6 × 250 mL = 1500 mL.

Total intake = 1500 + 100 + 100 + 1500 = 3200 mL.

The result in the answer key (2130 mL) would require a different interpretation of the 12-hour window or which infusions are counted; the straightforward calculation from the data given adds up to 3200 mL.
