A parent asked the nurse how to care for their 4-year-old child after receiving the Haemophilus influenzae Type b (Hib) conjugate vaccine.
Which instruction should the nurse provide?

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.

Choice A rationale:

Hyperglycemia is a key symptom of DKA. It occurs when there is an insufficient amount of insulin in the body to allow glucose to enter cells for use as energy. As a result, the body begins to break down fat for fuel, leading to the production of ketones and causing blood glucose levels to rise1. Normal blood glucose levels are between 4.0 to 6.0 mmol/L when fasting and up to 7.8 mmol/L two hours after eating2.

Choice B rationale:

Ketonuria, or the presence of ketones in the urine, is another symptom of DKA. When the body breaks down fat for energy, ketones are produced. If too many ketones build up in the blood, they can spill over into the urine1.

Choice C rationale:

Metabolic acidosis occurs in DKA due to the accumulation of ketones in the blood. Ketones are acidic, and when they build up in the blood, they cause the blood to become more acidic, leading to metabolic acidosis1.

Choice D rationale:

Hypokalemia is not a symptom of DKA. In fact, patients with DKA often have high potassium levels in their blood at presentation because acidosis causes potassium to move from inside the cells into the bloodstream1. However, during treatment for DKA, when insulin is administered and acidosis is corrected, potassium moves back into the cells and can lead to low potassium levels or hypokalemia1.

Choice E rationale:

Dehydration is a common symptom of DKA. High blood glucose levels lead to increased urination as the body tries to get rid of the excess glucose. This can result in dehydration1.

Choice F rationale:

Kussmaul respirations are a type of hyperventilation that occurs in DKA as the body tries to get rid of excess acids (ketones) through the lungs by breathing rapidly and deeply1.
