The nurse observes erythema under the chin of a client receiving oxygen at 2 L/minute per nasal cannula. Which intervention should the nurse implement?
A Place padding around the cannula tubing.
B Decrease the flow rate to 1 L/minute.
C Apply lubricant to the cannula tubing.
D Discontinue the use of the nasal cannula.
The Correct Answer is A
A. Placing padding around the cannula tubing is the appropriate intervention to address the erythema under the chin. This padding can help alleviate pressure and reduce skin irritation caused by the tubing. It's a proactive measure to prevent further discomfort or skin breakdown.
B. Decreasing the flow rate to 1 L/minute might not address the issue of pressure-related erythema, and it could compromise the client's oxygenation if not clinically indicated.
C. Applying lubricant to the tubing may not effectively reduce pressure or irritation caused by the tubing under the chin.
D. Discontinuing the use of the nasal cannula should be reserved for situations where it is medically necessary or if an alternative oxygen delivery method is available.

Correct Answer is ["0.8"]
Explanation
- Convert the client's weight from pounds to kilograms (kg).
- Calculate the enoxaparin sodium dosage per day based on the client's weight and the prescribed dosage of 1.5 mg/kg/day.
- Divide the enoxaparin sodium dosage by the concentration of the medication in the prefilled syringe (120 mg/0.8 mL) to determine the volume to administer.
Step 1: Convert weight from pounds to kilograms
-
- Client's weight in kg = Client's weight in pounds / 2.2
-
- Client's weight in kg = 176 pounds / 2.2 = 80 kg
Step 2: Calculate enoxaparin sodium dosage per day
-
- Enoxaparin sodium dosage (mg/day) = Client's weight (kg) × Prescribed dosage (mg/kg/day)
- Enoxaparin sodium dosage (mg/day) = 80 kg × 1.5 mg/kg/day = 120 mg/day
Step 3: Determine the volume to administer
-
- Volume to administer (mL) = Enoxaparin sodium dosage (mg/day) / Medication concentration (mg/mL)
- Volume to administer (mL) = 120 mg/day / (120 mg/0.8 mL) = 0.8 mL
Therefore, the nurse should administer 0.8 mL of enoxaparin sodium to the client.
Correct Answer is ["100"]
Explanation
- Total volume of the infusion: 50 mL (saline bag)
- Infusion time: 30 minutes = 0.5 hours (convert minutes to hours)
- We don't need the concentration of gentamicin for this calculation because we're only interested in the total volume delivered per hour.
- Flow rate: Since all the medication is delivered within the infusion time, the flow rate is equal to the total volume divided by the infusion time.
Flow rate (mL/hour) = Total volume (mL) / Infusion time (hours)
Flow rate = 50 mL / 0.5 hours Flow rate = 100.0 mL/hour
Therefore, the nurse should set the pump to deliver 100.0 mL/hour to infuse the 60 mg of gentamicin over 30 minutes.
