Which needle gauge should a nurse select when administering a medication subcutaneously?
8.
20.
21.
25.
The Correct Answer is D
The needle gauge size for subcutaneous injections should be between 25 and 31, depending on the patient’s size and the viscosity of the medication.
A smaller gauge number means a larger diameter needle, which can cause more pain and tissue damage.
Choice A is wrong because 8 is too large for subcutaneous injections and can cause bleeding and bruising.
Choice B is wrong because 20 is also too large for subcutaneous injections and can cause similar complications as choice A.
Choice C is wrong because 21 is still too large for subcutaneous injections and can cause discomfort and injury to the patient.
The needle length for subcutaneous injections should be between ½ inch and ⅝ inch, depending on the amount of subcutaneous tissue present. The nurse should pinch the skin and insert the needle at a 45-degree angle to ensure proper delivery of the medication.

Correct Answer is B
Explanation
This is because the nurse’s reply does not address the client’s fear of radiation therapy, but rather provides factual information that may not be relevant or helpful to the client.
The nurse is not using a therapeutic communication technique, such as reflecting, exploring, or validating the client’s feelings.
Instead, the nurse is shutting down the communication and missing an opportunity to learn more about the client’s concerns and needs.
Choice A is wrong because the nurse is not confronting a painful subject, but rather avoiding it.
The nurse is not acknowledging the client’s fear or inviting the client to talk more about it.
Choice C is wrong because the nurse is not recognizing that the client needs information, but rather assuming that the client does.
The nurse is not asking the client what he or she wants to know about radiation therapy, but rather telling the client what he or she should know.
Choice D is wrong because the nurse is not perceiving that the client is ready to hear more about the treatment, but rather imposing information on the client.
The nurse is not assessing the client’s readiness to learn, but rather giving unsolicited advice.
Correct Answer is C
Explanation
This is the priority action because it follows the RACE acronym for fire safety: Rescue, Alarm, Contain, Extinguish. The nurse should first rescue the client from immediate danger by smothering the flames with a blanket.
This will also help contain the fire and prevent it from spreading.
Choice A is wrong because closing the window and removing the client’s oxygen will not put out the fire.
Oxygen is not flammable, but it can make a fire burn faster and hotter. Removing the oxygen source may help reduce the intensity of the fire, but it will not extinguish it.
Choice B is wrong because sounding the fire alarm and activating the emergency response system are important steps, but they are not the priority. The nurse should first ensure the client’s safety before alerting others and calling for help.
Choice D is wrong because removing the client from the room and closing the door may expose the client to more harm and make the fire worse.
The nurse should not move the client unless it is absolutely necessary, as this may cause further injury or infection. Closing the door may create a backdraft, which is a sudden explosion of fire caused by oxygen rushing into an enclosed space.
