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 D
Explanation
Ineffective Airway Clearance. This is because a client with a Glasgow Coma Scale (GCS) of 6 has a severe impairment of consciousness and is at risk of aspiration, respiratory failure, and infection. The GCS is a clinical scale that measures a person’s level of consciousness after a brain injury based on their eye, verbal and motor responses. A GCS score of 6 indicates that the client only opens eyes to pain, makes incomprehensible sounds and shows abnormal flexion to pain.
Choice A is wrong because Acute Confusion is not a priority nursing diagnosis for a client with a GCS of 6.
Acute Confusion is a state of disorientation and impaired memory that can be caused by various factors such as medication, infection, electrolyte imbalance or dementia.
A client with a GCS of 6 is not likely to be confused, but rather unresponsive or minimally responsive.
Choice B is wrong because Self-Care Deficit is not a priority nursing diagnosis for a client with a GCS of 6.
Self-care deficit is the impaired ability to perform activities of daily living such as bathing, dressing, feeding or toileting.
A client with a GCS of 6 will need assistance with all these activities, but the most urgent concern is their airway patency and oxygenation.
Choice C is wrong because Risk for Impaired Skin Integrity is not a priority nursing diagnosis for a client with a GCS of 6.
Risk for Impaired Skin Integrity is the potential for damage to the skin or underlying tissues due to pressure, friction, shear or moisture.
A client with a GCS of 6 may be at risk for developing pressure ulcers or skin breakdown due to immobility and reduced sensation, but this is not as life-threatening as ineffective airway clearance.
Correct Answer is B
Explanation
This meal selection best demonstrates a client with osteoporosis understands dietary recommendations because it provides adequate amounts of calcium, vitamin D, and protein, which are essential nutrients for bone health.
Choice A is wrong because chicken, carrots, and fresh grapefruit salad do not provide enough calcium or vitamin D for a person with osteoporosis.
Calcium is mainly found in dairy products, leafy green vegetables, and fish with bones. Vitamin D is mainly found in fatty fish, egg yolks, and fortified foods.
Choice C is wrong because green salad, ground beef patty, corn, and applesauce do not provide enough calcium or vitamin D for a person with osteoporosis.
Green salad may contain some calcium depending on the type of greens, but it is not a rich source.
Ground beef patty and corn are low in calcium and vitamin
D. Applesauce does not contain any calcium or vitamin
D. Choice D is wrong because plain omelet, bacon, toast with butter, and strawberries do not provide enough calcium or vitamin D for a person with osteoporosis.
Plain omelet and bacon are high in protein but low in calcium and vitamin
Toast with butter may contain some vitamin D if the bread or butter are fortified, but it is not a rich source.
Strawberries do not contain any calcium or vitamin
