A patient has an order for a subcutaneous injection of insulin.
Into which of the following tissues will the nurse prepare to give this injection?
Into the patient’s intravenous line.
Into the patient’s vastus lateralis.
Into the fatty tissue of the patient’s abdomen.
Into the patient’s deltoid.
The Correct Answer is C
Choice A rationale:
Intravenous (IV) administration delivers medication directly into the bloodstream. This route is not appropriate for insulin because it would result in a rapid and potentially dangerous drop in blood glucose levels. Insulin needs to be absorbed more slowly to mimic the natural release of insulin from the pancreas.
IV administration also requires sterile technique and specialized equipment, making it more complex and time-consuming than subcutaneous injection.
Additionally, there is a higher risk of infection and other complications with IV administration.
Choice B rationale:
The vastus lateralis is a muscle in the thigh that is commonly used for intramuscular (IM) injections. However, IM injections are not typically used for insulin administration because they can be more painful and have a slower absorption rate than subcutaneous injections.
IM injections also carry a higher risk of hitting a blood vessel, which could lead to erratic absorption of insulin.
Choice D rationale:
The deltoid is a muscle in the upper arm that can be used for subcutaneous injections. However, the abdomen is generally the preferred site for insulin injection because it has a greater amount of subcutaneous fat, which helps to slow the absorption of insulin and provide a more consistent effect.
The abdomen is also a more convenient site for self-injection, as it is easily accessible.
Choice C rationale:
The fatty tissue of the abdomen is the ideal site for subcutaneous insulin injection because it provides slow and consistent absorption of insulin.
The abdomen has a rich blood supply, which helps to distribute the insulin throughout the body.
The subcutaneous tissue in the abdomen is relatively thin, which makes it easy to inject insulin without causing pain or discomfort.
The abdomen is also a large area, which allows for multiple injection sites to be used and rotated to prevent lipohypertrophy (thickening of the subcutaneous tissue).

Correct Answer is D
Explanation
Choice A rationale:
Incorrect because swallowing the tablet with water would lead to slower absorption and a delayed onset of action. Nitroglycerin is rapidly absorbed through the oral mucosa, and swallowing it would route it through the digestive system, where it would be absorbed more slowly and less effectively.
Swallowing the tablet could also increase the risk of side effects, such as headache and flushing, due to the larger amount of the drug that would be absorbed systemically.
Choice B rationale:
Incorrect because crushing the tablet and dissolving it in water would also delay its absorption. This method would require the tablet to dissolve in the water before it could be absorbed through the oral mucosa, which would slow down the onset of action.
Crushing the tablet could also damage the medication and make it less effective.
Choice C rationale:
Incorrect because placing the tablet in the patient's mouth next to the cheek would not allow for optimal absorption. The oral mucosa under the tongue is more permeable than the cheek, so placing the tablet under the tongue allows for faster and more efficient absorption.
Placing the tablet in the cheek could also increase the risk of the patient accidentally swallowing it.
Choice D rationale:
Correct because placing the tablet under the patient's tongue allows for rapid absorption and a quick onset of action. The sublingual route is the preferred method of administration for nitroglycerin because it allows the medication to bypass the digestive system and be absorbed directly into the bloodstream.
This method also allows for the patient to easily remove the tablet if they experience any side effects.
Correct Answer is C
Explanation
Choice A rationale:
Burning dried herbs is a form of traditional medicine, not allopathic medicine.
Traditional medicine encompasses a wide range of practices and therapies that have been used for centuries across different cultures.
It often relies on natural substances and processes, such as herbs, acupuncture, and massage, to promote healing and well- being.
While traditional medicine can offer valuable benefits, it's important to note that it's not always based on scientific evidence and its efficacy can vary depending on the specific practice and condition being treated.
Choice B rationale:
Tai chi exercises are a form of complementary and alternative medicine (CAM), not allopathic medicine.
CAM encompasses a diverse group of therapies that are not considered part of mainstream conventional medicine. Tai chi is a mind-body practice that involves gentle, flowing movements and deep breathing.
It has been shown to offer a range of health benefits, including reducing stress, improving balance, and easing pain.
However, it's important to note that tai chi is not a cure-all and should not be used as a substitute for conventional medical care when necessary.
Choice C rationale:
Prescription of antibiotic medication is a hallmark of allopathic medicine.
Allopathic medicine, also known as conventional or Western medicine, is based on the scientific understanding of the body and disease.
It focuses on diagnosing and treating specific diseases or conditions using medications, surgery, or other interventions that have been proven effective through rigorous scientific research.
Antibiotics are a type of medication that specifically targets and kills bacteria.
They are essential for treating bacterial infections, which can cause a wide range of illnesses, from minor skin infections to life- threatening pneumonia.
Choice D rationale:
Manipulation of the spine, also known as chiropractic care, is a form of CAM, not allopathic medicine. Chiropractic care focuses on the musculoskeletal system, particularly the spine.
Chiropractors use manual adjustments to the spine to relieve pain, improve range of motion, and restore function.
While some studies have shown that chiropractic care can be effective for certain conditions, such as lower back pain, it's important to note that it's not a cure-all and should not be used as a substitute for conventional medical care when necessary.
