Which insulin can be administered intravenously?

Regular insulin

Rapid acting insulin

Long acting insulin

Intermediate acting

Answer and Explanation

The Correct Answer is A

A. Regular insulin: Regular insulin is the only type of insulin approved for intravenous administration. It is commonly used in emergency situations like diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS) due to its predictable onset and short duration when given IV.

B. Rapid acting insulin: Although rapid-acting insulins such as lispro or aspart act quickly when given subcutaneously, they are not used intravenously because their pharmacokinetics are less predictable via this route, and they are not approved for IV use.

C. Long acting insulin: Long-acting insulins like glargine or detemir are formulated to release slowly over an extended period and are never given IV. Intravenous administration would disrupt their controlled-release mechanism and lead to unpredictable effects.

D. Intermediate acting: Intermediate-acting insulin, such as NPH, contains protamine to delay absorption, making it unsuitable for IV use. Administering it intravenously would result in erratic absorption and action, posing safety risks.

Correct Answer is D

Explanation

A. cascara: Cascara is a natural stimulant laxative that promotes bowel movements by irritating the colon. It would increase gastrointestinal motility and worsen the client's ileostomy output, making it inappropriate in this situation.

B. octreotide: Octreotide is used for severe secretory diarrhea or conditions like carcinoid syndrome, but it is generally reserved for more complex cases and not first-line for managing high ileostomy output. It is also costly and requires subcutaneous or IV administration.

C. psyllium: Psyllium is a bulk-forming laxative that absorbs water and increases stool bulk to help with constipation. In clients with an ileostomy, it can risk causing obstruction or be ineffective at slowing output and is not typically recommended.

D. loperamide: Loperamide is an antidiarrheal that slows intestinal motility, allowing for increased absorption of fluids and electrolytes. It is commonly prescribed to manage high-output ileostomies.

A. diazole oral B. glyburide oral C. glucagon intravenous injection D. insulin subcutaneous injection

Correct Answer is C

Explanation

A. diazole oral: There is no widely used hypoglycemia treatment called "diazole."

B. glyburide oral: Glyburide is an oral hypoglycemic agent used to lower blood glucose in clients with type 2 diabetes. Administering it during a hypoglycemic crisis would worsen the condition by further reducing glucose levels.

C. glucagon intravenous injection: Glucagon stimulates glycogen breakdown in the liver, raising blood glucose levels rapidly. For a glucose level as low as 19 mg/dL, immediate IV administration is warranted when IV dextrose is unavailable or if rapid response is needed in an unconscious patient.

D. insulin subcutaneous injection: Insulin administration in a hypoglycemic patient would exacerbate the condition, potentially leading to seizures, coma, or death. Insulin is contraindicated in hypoglycemia and should never be given in such a situation.
