Which of the following conditions could potentially lead to a gastrointestinal bleed? (Select all that apply.)

Choice A rationale
Pancreatitis can lead to gastrointestinal bleeding. Inflammation of the pancreas can cause damage to the organ’s blood vessels, leading to bleeding. This can be a serious complication of pancreatitis.
Choice B rationale
Peptic ulcer disease is a common cause of gastrointestinal bleeding. Ulcers are sores that develop on the lining of the stomach, upper small intestine, or esophagus. When these ulcers erode into blood vessels, bleeding can occur.
Choice C rationale
Inflammatory bowel disease (IBD), which includes conditions like Crohn’s disease and ulcerative colitis, can cause ulcers in the digestive tract. These ulcers can bleed, leading to gastrointestinal bleeding.
Choice D rationale
Gastrointestinal malignancy, or cancer, can cause gastrointestinal bleeding. Tumors can erode into blood vessels or cause ulcers that bleed.
Choice E rationale
Diverticulosis involves the formation of small pouches in the wall of the digestive tract. These pouches can bleed, leading to gastrointestinal bleeding.
Choice F rationale
Gallbladder disease typically does not cause gastrointestinal bleeding. The gallbladder stores bile, a fluid produced by the liver to digest fats. While gallstones and inflammation of the gallbladder are common, they do not usually lead to gastrointestinal bleeding.
Choice G rationale
Hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone, is not typically associated with gastrointestinal bleeding. Symptoms of hypothyroidism can include fatigue, weight gain, and depression, but not gastrointestinal bleeding.

Choice A rationale
The abdomen is a common site for subcutaneous injections because it allows for consistent absorption. The area above the iliac crest is often used because it is easy to access and usually has enough subcutaneous tissue for the injection.
Choice B rationale
A 1-inch needle is typically too long for a subcutaneous injection. A shorter needle (usually 1/2 to 5/8 inch) is usually used to ensure the medication is delivered to the subcutaneous tissue.
Choice C rationale
A 22-gauge needle is typically too large for a subcutaneous injection. Smaller gauge needles (usually 25-27 gauge) are usually used for subcutaneous injections.
Choice D rationale
Massaging the injection site after administration of heparin is not recommended. It can cause the medication to be absorbed too quickly and can also lead to bruising.
