A client with intestinal obstruction has a nasogastric tube to low intermittent suction and is receiving an intravenous (IV) infusion of lactated Ringer's at 100 mL/hour.
Which finding is most important for the nurse to report to the healthcare provider? Reference Range: Potassium (3.5 to 5 mEq/L (3.5 to 5 mmol/L).

Choice A rationale:

A pH level of 7.35 to 7.45 and HCO3- level of 22 to 26 mEq/L indicate a resolution of ketoacidosis. The normal pH range for the body is 7.35 to 7.45, and a return to this range indicates that the body’s acid-base balance has been restored. The bicarbonate (HCO3-) level is a measure of the metabolic component of the body’s acid-base balance, and the normal range is 22 to 26 mEq/L. A return to this range indicates that the metabolic acidosis caused by the ketoacidosis has been resolved.

Choice B rationale:

A pH level of 7.25 to 7.35 and HCO3- level of 18 to 22 mEq/L would indicate that the client is still in a state of mild acidosis, as the pH is below the normal range and the bicarbonate level is also slightly low, indicating a metabolic acidosis.

Choice C rationale:

A pH level of 7.15 to 7.25 and HCO3- level of 14 to 18 mEq/L would indicate a moderate acidosis. Both the pH and bicarbonate levels are significantly below their normal ranges, indicating a significant disruption in the body’s acid-base balance.

Choice D rationale:

A pH level of 7.05 to 7.15 and HCO3- level of 10 to 14 mEq/L would indicate severe acidosis, which would be life-threatening if not corrected. Both the pH and bicarbonate levels are far below their normal ranges, indicating a severe disruption in the body’s acid-base balance. In conclusion, choice A is correct because it represents values within the normal ranges for both pH and bicarbonate, indicating a resolution of ketoacidosis.

When the practical nurse (PN) notices that one of the unlicensed assistive personnel (UAP) consistently records subnormal temperatures when using the thermometer, the first action the PN should take is to observe how the UAP obtains temperatures. This allows the PN to directly assess the UAP's technique and determine if any errors or inaccuracies are occurring during temperature measurement. By observing the process, the PN can identify any potential issues, such as incorrect placement of the thermometer or improper technique, and provide appropriate guidance and education.
Let's evaluate the other options:

a) Show the UAP how to chart temperatures.
While accurate charting of temperatures is important, it is not the primary concern in this situation. The PN should first focus on assessing the UAP's temperature measurement technique before addressing charting skills.

b) Return the thermometer for recalibration.
Returning the thermometer for recalibration may be necessary if there is evidence or suspicion of a malfunctioning thermometer. However, before assuming that the thermometer is the issue, it is important to first observe how the UAP obtains temperatures to rule out any human error in the measurement process.

d) Demonstrate how to use the equipment.
Demonstrating how to use the equipment may be beneficial, but it should not be the first action taken in this scenario. The PN should first observe the UAP's technique to identify any potential errors or issues in temperature measurement. Based on the observation, the PN can provide specific guidance and demonstrate the correct technique if necessary.

In summary, when a practical nurse (PN) notices that a UAP consistently records subnormal temperatures when using the thermometer, the first action the PN should take is to observe how the UAP obtains temperatures. This allows for direct assessment of the UAP's technique and identification of any potential errors or issues. Based on the observation, the PN can provide appropriate guidance, education, and intervention as needed to ensure accurate temperature measurement.
