Which of the following triggers the pancreas to secrete insulin?

A.

Hypoglycemia

B.

Hyperglycemia

C.

Glucagon

D.

Ketoacids

Answer and Explanation

The Correct Answer is B

Choice A rationale
 
Hypoglycemia, or low blood sugar, does not trigger the pancreas to secrete insulin. In fact, it’s the opposite. When blood sugar levels are low, the pancreas secretes glucagon, a hormone that signals the liver to release stored glucose into the bloodstream.
Choice B rationale
Hyperglycemia, or high blood sugar, is the primary trigger for the pancreas to secrete insulin. Insulin is a hormone that helps move glucose from the blood into the cells where it can be used for energy. When blood glucose levels rise, such as after a meal, the pancreas releases more insulin.
Choice C rationale
Glucagon is a hormone produced by the pancreas that works with insulin to control blood sugar levels. However, it does not trigger the pancreas to secrete insulin. Instead, glucagon acts when blood sugar levels are low, signaling the liver to release stored glucose into the bloodstream.
Choice D rationale
Ketoacids, or ketones, are substances made when the body breaks down fat for energy. The production of ketones is usually a sign that the body is not getting enough glucose for energy. However, they do not trigger the pancreas to secrete insulin.

Choice A rationale

Choice C rationale
Obtaining a PTT (partial thromboplastin time) is not typically necessary before administering antibiotics for a urinary tract infection.
Choice D rationale
Obtaining a platelet count is not typically necessary before administering antibiotics for a urinary tract infection.

Correct Answer is D

Explanation

The correct answer is = D. Foods that contain tyramine and caffeine

Here's the rationale for each choice:

  • Choice A rationale: Large amounts of water are generally safe for people taking MAOIs and can even help prevent dehydration, which can worsen some side effects.
  • Choice B rationale: A diet high in salt may raise blood pressure, but it's not a specific concern related to the interaction of MAOIs with food.
  • Choice C rationale: A diet high in fat doesn't directly interact with MAOIs. While a healthy diet is recommended overall, fat content isn't a primary concern.
  • Choice D rationale: Foods containing tyramine and caffeine can interact with MAOIs, potentially leading to a dangerous increase in blood pressure. MAOIs inhibit the breakdown of these substances, so avoiding them is crucial.

Therefore, clients taking MAOIs should be instructed to avoid foods high in tyramine and caffeine.
