Which needle gauge should a nurse select when administering a medication subcutaneously?

20.

21.

25.

Answer and Explanation

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 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.

A. Tarry-colored stools. B. Swelling of the leg and knee. C. Right upper quadrant discomfort. D. Bruising around the injured knee.

Correct Answer is A

Explanation

This is because aspirin can cause gastrointestinal bleeding, ulceration, and perforation as side effects. Tarry-colored stools indicate the presence of blood in the stool, which is a sign of bleeding in the upper gastrointestinal tract.

This is a serious condition that requires immediate medical attention.

Choice B. Swelling of the leg and knee is wrong because it is not related to aspirin use.

It may indicate inflammation, infection, or injury of the leg and knee, but it is not a priority symptom to report to the HCP.

Choice C. Right upper quadrant discomfort is wrong because it is not related to aspirin use.

It may indicate liver or gallbladder problems, but it is not a priority symptom to report to the HCP.

Choice D. Bruising around the injured knee is wrong because it is not related to aspirin use.

It may indicate trauma, bleeding disorders, or coagulation problems, but it is not a priority symptom to report to the HCP.

Normal ranges for bleeding time are 2 to 7 minutes. Normal ranges for PTT are 25 to 35 seconds. Normal ranges for liver enzymes are AST 10 to 40 U/L and ALT 7 to 56 U/L.
