A client receiving mechanical ventilation has a pH of 7.26, PaCO2 of 68 mm Hg, and a PaO2 of 92 mm Hg. Which intervention should the nurse implement?
Decrease expiratory flow time.
Decrease expiratory pressure.
Increase rate of ventilation.
Increase ventilator tidal volume.
The Correct Answer is C
The correct answer is choice C: Increase rate of ventilation.
Choice A rationale:
Decreasing expiratory flow time would not directly address the elevated PaCO2 levels. This intervention is more related to managing expiratory phase issues rather than correcting respiratory acidosis.
Choice B rationale:
Decreasing expiratory pressure might help with certain ventilation issues, but it does not specifically target the elevated PaCO2 and resulting acidosis.
Choice C rationale:
Increasing the rate of ventilation helps to blow off more CO2, thereby reducing PaCO2 levels and correcting the respiratory acidosis indicated by the pH of 7.26 and PaCO2 of 68 mm Hg.
Choice D rationale:
Increasing the ventilator tidal volume could also help reduce PaCO2 by increasing the amount of air exchanged with each breath. However, increasing the rate of ventilation is generally a more immediate and effective intervention for acute respiratory acidosis.

Correct Answer is B
Explanation
- A bowel patern is the frequency, consistency, and appearance of a person's bowel movements. A normal bowel patern is what's normal for each person, and it can vary depending on factors such as diet, age, physical activity, and health conditions.
- A focused gastrointestinal system assessment includes collecting subjective data about the patient's history of gastrointestinal disease, signs and symptoms of gastrointestinal problems, diet and nutrition, and bowel patern. It also includes inspecting and auscultating the abdomen for any abnormalities³.
- When a client reports having a bowel movement three days ago, the first action that the practical nurse should implement is to determine the client's usual bowel patern. This will help to evaluate if the client is experiencing constipation or if this is their normal frequency. It will also help to identify any changes or risk factors that may affect the client's bowel function.
Therefore, option B is the correct answer, while options A, C, and D are incorrect.
Option A is incorrect because administering a stool softener without assessing the client's bowel patern may not be appropriate or effective.
Option C is incorrect because encouraging ambulation may help to stimulate bowel activity, but it is not the first action to take.
Option D is incorrect because recommending dietary changes may be helpful for preventing or treating constipation, but it is not the first action to take.
Correct Answer is C
Explanation
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.
