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 A
Explanation
Choice A Reason: This is correct because measuring temperature at regular intervals allows the nurse to monitor fever patterns and evaluate the effectiveness of interventions.
Choice B Reason: This is incorrect because assessing for flushed, warm skin regularly is not a reliable indicator of fever. Skin temperature may vary depending on environmental factors and blood flow.
Choice C Reason: This is incorrect because varying sites for temperature measurement may result in inaccurate readings. Different sites have different normal ranges and may be affected by external factors.
Choice D Reason: This is incorrect because documenting the client's circadian rhythms is not relevant to assessing fever patterns. Circadian rhythms are natural fluctuations in body functions that occur over a 24-hour cycle.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect because contacting the healthcare provider about the frequency of pain medication is a dependent intervention that requires an order from the provider. The nurse should first use independent interventions such as reviewing available prescriptions or providing non-pharmacological measures.
Choice B Reason: This is incorrect because encouraging the client to allow more time for the medication to work can imply that the nurse does not believe or validate the client's report of pain. It also can delay effective pain relief and increase suffering.
Choice C Reason: This is correct because reviewing the medical record for additional pain medication prescriptions can help identify alternative or adjunctive options for pain management, such as breakthrough doses, rescue doses, or non-opioid analgesics.
Choice D Reason: This is incorrect because administering an additional dose of morphine sulfate 0.2 mg intravenously can cause overdose, respiratory depression, or addiction. The nurse should follow the prescribed dosage, route, and interval of administration and monitor for adverse effects.
