Which criterion should a nurse use to determine the proper length of the needle to administer a subcutaneous (subcut) medication?
Age of the client.
Viscosity of the solution.
Amount of adipose tissue over the muscle.
Quantity of the solution to be administered.
The Correct Answer is C
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 A
Explanation
“I will discard unused pills after six months after replacing it with a new vial.” This statement indicates that the client understands that nitroglycerin tablets lose their potency over time and need to be replaced regularly.
Choice B is wrong because nitroglycerin can cause headaches as a side effect, but the client should not stop taking it if they have chest pain. They can use Tylenol for pain relief.
Choice C is wrong because nitroglycerin can cause hypotension and dizziness, so the client should avoid lying down or changing positions suddenly after taking it. They should sit or stand still until the chest pain subsides.
Choice D is wrong because a tingling feeling on the tongue is a normal sensation when taking sublingual nitroglycerin and does not indicate an adverse reaction. It also confirms that the tablet is potent and effective.
Correct Answer is D
Explanation
Emptying the urine drainage bags at least once per shift is a task that can be delegated to unlicensed assistive personnel (UAP) assigned to a cardiac surgery unit.
This task does not require assessment, teaching, or evaluation skills that are beyond the scope of practice of UAP.
Choice A is wrong because teaching a client how to use a pillow to support an incision when coughing requires education and evaluation skills that are only within the scope of practice of licensed nurses.
Choice B is wrong because checking the pedal pulses of bed-bound clients requires assessment skills that are only within the scope of practice of licensed nurses.
Pedal pulses are important indicators of peripheral circulation and vascular status.
Choice C is wrong because ambulating the first-day postoperative clients requires assessment and evaluation skills that are only within the scope of practice of licensed nurses.
First-day postoperative clients may have complications such as bleeding, infection, or hypotension that need to be monitored by a nurse.
