Endocrine System Nursing Questions Questions
Question 1 of 5
Most hormones of the endocrine system are regulated by a .
Correct Answer: C
Rationale: The correct answer is C: negative feedback mechanism. This is because the majority of hormones in the endocrine system are regulated by a feedback loop that maintains homeostasis by inhibiting further hormone production when levels are too high and stimulating production when levels are too low. This negative feedback mechanism ensures that hormone levels remain within a narrow range. A: hormone-gene complex is incorrect as hormones are not primarily regulated by direct interactions with genes. B: hormone-receptor complex is incorrect as receptors are involved in hormone action, not regulation. D: positive feedback mechanism is incorrect as it would lead to an amplification of hormone production, which is not typically seen in the endocrine system to maintain stability.
Question 2 of 5
The small intestine runs from the stomach to the large intestine. It has three parts. Starting at the stomach, in which order do they occur?
Correct Answer: D
Rationale: The correct order is D: Duodenum, jejunum, ileum. The duodenum is the first part of the small intestine connected to the stomach for digestion. Next is the jejunum, where most of the nutrients are absorbed. Lastly, the ileum completes the absorption process before reaching the large intestine. Choice A is incorrect as it has the parts in the wrong order. Choice B also has the parts in the wrong order. Choice C has the duodenum and ileum in the correct position but switches the jejunum and ileum.
Question 3 of 5
Which of the following is not a similarity between hormones and neurotransmitters?
Correct Answer: A
Rationale: The correct answer is A because it states that none of the above choices are similarities between hormones and neurotransmitters. This is accurate as choices B, C, and D all highlight similarities between hormones and neurotransmitters. Choice B is correct as both are chemical messengers, choice C is correct because some hormones and neurotransmitters can be chemically identical, and choice D is correct because both produce molecules that act on receptors. Therefore, A is the correct choice as it states that there are no similarities between the two, which is not the case.
