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 C
Explanation
The proper length of the needle to administer a subcutaneous injection depends on the amount of adipose tissue over the muscle.
The needle should be long enough to reach the subcutaneous layer but not so long that it penetrates the muscle. The needle gauge and length vary depending on the patient’s size and the injection site
Choice A is wrong because the age of the client does not determine the needle length.
However, age may affect the amount of adipose tissue and muscle mass, which are factors to consider when choosing a needle length.
Choice B is wrong because the viscosity of the solution does not determine the needle length. However, viscosity may affect the needle gauge, which is the diameter of the needle.
Thicker solutions may require larger gauge needles to allow easier flow.
Choice D is wrong because the quantity of the solution does not determine the needle length.
However, quantity may affect the syringe size, which is the volume of medication that can be held by the syringe.
The syringe size should match the prescribed dose as closely as possible to ensure accuracy and ease of measurement.
Correct Answer is B
Explanation
The nurse should prioritize the physical safety and stability of the patient who has been raped and stabbed.
Assessing vital signs is the first step in determining the patient’s condition and identifying any life-threatening injuries that need immediate intervention.
Choice A is wrong because calling the Sexual Nurse Examiner is not the first action to take.
The Sexual Nurse Examiner is a specially trained nurse who can perform a forensic examination and collect evidence from the patient, but this should be done after ensuring the patient’s physical safety and obtaining consent.
Choice C is wrong because calling her parents to ask for permission to treat her is not necessary or appropriate.
The patient is an adult who can consent to her own treatment unless she is incapacitated or mentally incompetent.
Calling her parents without her permission may violate her privacy and autonomy.
Choice D is wrong because contacting Security in case the perpetrator arrives is not the most urgent action to take.
The nurse should focus on the patient’s needs and not assume that the perpetrator will follow her to the hospital.
Security measures can be taken later if needed.
