After obtaining an oxygen saturation level of 94% for a client with pneumonia who is receiving oxygen via nasal cannula at 3 L/minute, the nurse observes a red mark on the client's right cheek. Which intervention should the nurse implement?

Discontinue the use of the nasal cannula.

Apply lubricant to the cannula tubing.

Place padding around the cannula tubing.

Decrease the flow rate to 1 L/minute.

Answer and Explanation

The Correct Answer is C

The correct answer is choice c. Place padding around the cannula tubing.

Choice A rationale:

Discontinuing the use of the nasal cannula is not appropriate because the client still needs supplemental oxygen to maintain adequate oxygen saturation levels.

Choice B rationale:

Applying lubricant to the cannula tubing might help reduce friction but does not address the pressure that is causing the red mark.

Choice C rationale:

Placing padding around the cannula tubing helps to alleviate the pressure on the skin, which can prevent further irritation and allow the red mark to heal.

Choice D rationale:

Decreasing the flow rate to 1 L/minute could compromise the client’s oxygenation status, as the current flow rate is necessary to maintain an oxygen saturation level of 94%.

Correct Answer is D

Explanation

Choice A reason: Leaving the dressing off is not advisable as it can expose the wound to potential infection and delay healing.

Choice B reason: A transparent dressing may not be the best choice for a stage 3 pressure injury with significant granulation tissue.

Choice C reason: Increasing the frequency of dressing changes without specific orders may not be necessary and could disrupt the healing process.

Choice D reason: A hydrocolloid gel dressing is appropriate for a stage 3 pressure injury as it maintains a moist environment, which is conducive to wound healing and granulation.

A. Serum potassium: 3.5 mEq/L (3.5 mmol/L), serum sodium: 142 mEq/L (142 mmol/L) B. Serum potassium: 4.5 mEq/L (4.5 mmol/L), serum sodium: 140 mEq/L (140 mmol/L) C. Serum potassium: 5.0 mEq/L (5.0 mmol/L), serum sodium: 138 mEq/L (138 mmol/L) D. Serum potassium: 3.0 mEq/L (3.0 mmol/L), serum sodium: 149 mEq/L (149 mmol/L)

Correct Answer is A

Explanation

Choice A reason: The results are within the normal reference range for both potassium and sodium, which is expected unless the client's condition has led to significant electrolyte imbalances.

Choice B reason: A serum potassium level of 4.5 mEq/L is at the higher end of the normal range, which might not be expected in a client with vomiting and diarrhea, conditions that often lead to lower potassium levels.

Choice C reason: A serum potassium level of 5.0 mEq/L is at the upper limit of the normal range and could indicate hyperkalemia, especially in the context of severe dehydration.

Choice D reason: A serum sodium level of 149 mEq/L is slightly above the normal range and could indicate hypernatremia, which may occur in dehydration but would require further assessment and intervention.
