A nurse is caring for a client who had IV fluids initiated at 0330. The IV fluids are infusing at 120 mL/hr. The nurse should record how many mL of IV fluids on the intake record at 0600?
The Correct Answer is ["300"]
To calculate the volume of IV fluids infused from 0330 to 0600, you would determine the number of hours that have passed.
From 0330 to 0600 is 2.5 hours. Since the IV is infusing at 120 mL/hr, you would multiply the infusion rate by the number of hours. So, 120 mL/hr * 2.5 hours = 300 mL.
Therefore, the nurse should record 300 mL of IV fluids on the intake record at 0600.

Correct Answer is D
Explanation
A. PaCO2 (partial pressure of carbon dioxide) reflects the respiratory component of acid-base balance. In metabolic acidosis, the respiratory system compensates by increasing ventilation to decrease PaCO2 (hyperventilation). Therefore, PaCO2 is typically below normal (less than 35-45 mm Hg) in metabolic acidosis, not above 45 mm Hg.
B. HCO3 (bicarbonate) is a buffer that helps regulate pH in the body. In metabolic acidosis, there is a primary decrease in HCO3 due to either increased acid production (e.g., lactic acidosis, ketoacidosis) or decreased acid elimination (e.g., renal failure). Therefore, HCO3 is typically below normal (< 22-26 mEq/L) in metabolic acidosis, not above 26 mEq/L.
C. PaO2 (partial pressure of oxygen) measures the oxygen level in the blood. It is not directly related to the diagnosis of metabolic acidosis. Low PaO2 levels may indicate respiratory dysfunction or impaired gas exchange but are not specific to metabolic acidosis.
D. pH below 7.35 indicates acidosis. In metabolic acidosis, the primary defect is a decrease in blood pH due to an excess of acids or a loss of bases. The pH typically decreases below the normal range of 7.35-7.45 in metabolic acidosis.
Correct Answer is A
Explanation
A. This condition occurs because the suctioning can lead to a significant loss of hydrochloric acid from the stomach. Since hydrochloric acid is one of the components that maintain the acid-base balance in the body, its loss can lead to an increase in blood pH, causing alkalosis
B. Respiratory acidosis occurs due to retention of carbon dioxide (CO2), leading to an increase in PaCO2 and a decrease in pH. In the context of a small bowel obstruction with nasogastric tube suctioning, this is less likely unless there are concurrent respiratory issues.
C. This condition occurs because the suctioning can lead to a significant loss of hydrochloric acid from the stomach. Since hydrochloric acid is one of the components that maintain the acid-base balance in the body, its loss can lead to an increase in blood pH, causing alkalosis. Acidosis is, therefore, unlikely.
D. Respiratory alkalosis occurs due to hyperventilation, leading to a decrease in PaCO2 and an increase in pH. This is less likely in the context of nasogastric tube suctioning unless there are other contributing factors.
