The nurse plans to administer naloxone 1 mg. The label of the 10 mL vial indicates that the drug concentration is 0.4 mg/mL. How many mL should the nurse administer?
(Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2.5"]
To find the volume of the solution needed, the nurse can use the formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Substituting the given values, we get:
Volume (mL) = 1 mg / 0.4 mg/mL
Simplifying, we get:
Volume (mL) = 2.5 mL
Therefore, the nurse should administer 2.5 mL of naloxone to give a dose of 1 mg.

Correct Answer is B
Explanation
Choice A Reason: This is incorrect because decreasing the flow rate to 1 L/minute can compromise the client's oxygenation and worsen hypoxia. The client's oxygen saturation level is below the normal range of 95% to 100%.
Choice B Reason: This is correct because placing padding around the cannula tubing can prevent pressure ulcers and skin breakdown caused by friction and irritation from the tubing.
Choice C Reason: This is incorrect because applying lubricant to the cannula tubing can increase the risk of infection and inflammation of the nasal mucosa. Lubricant should be applied sparingly to the nares only if needed.
Choice D Reason: This is incorrect because discontinuing the use of the nasal cannula can endanger the client's life and cause respiratory failure. The client needs supplemental oxygen to maintain adequate oxygenation.

Correct Answer is C
Explanation
Choice A: Limitations to range of motion are not directly related to the application of a heating pad. A heating pad may help reduce pain and stiffness, but it does not affect the range of motion itself.
Choice B: Muscle strength and tone are also not directly related to the application of a heating pad. A heating pad may relax tense muscles, but it does not affect the strength or tone of the muscles.
Choice C: Degree of neurosensory impairment is the most important assessment for the nurse to perform prior to the application of a heating pad. A heating pad can cause burns or tissue damage if the patient has impaired sensation and cannot feel the heat or pain. The nurse should check the patient's ability to perceive temperature, pressure, and pain before applying a heating pad.
Choice D: Presence of rebound phenomenon is not relevant to the application of a heating pad. Rebound phenomenon refers to the worsening of symptoms after discontinuing a medication or treatment. A heating pad does not cause rebound phenomenon.
