Which of the following is the property in which a hormone CANNOT exhibit its full effect without another hormone?
- A. assertiveness
- B. antagonism
- C. synergism
- D. permissiveness
Correct Answer: D
Rationale: The correct answer is D: permissiveness. Permissiveness is when one hormone enables another hormone to fully exert its effects. The rationale is as follows:
1. Permissiveness allows a hormone to work effectively only when another hormone is present to "permit" its action.
2. Assertiveness (A) and antagonism (B) do not involve the requirement of another hormone for full effect.
3. Synergism (C) involves two hormones working together for a greater effect, but they can still exert some effect individually.
In summary, permissiveness is the only option where a hormone cannot exhibit its full effect without the presence of another hormone.

Priority Decision: The nurse is assessing a newly admitted diabetic patient. Which observation should be addressed as the priority by the nurse?
- A. Bilateral numbness of both hands
- B. Rapid respirations with deep inspiration
- C. Stage II pressure ulcer on the right heel
- D. Areas of lumps and dents on the abdomen
Correct Answer: C
Rationale: Rapid respirations with deep inspiration may indicate diabetic ketoacidosis (DKA), which is a medical emergency.
A man has been told that he is not synthesizing enough follicle-stimulating hormone (FSH), and for this reason he may be unable to father a child. Choose the correct statement to explain this problem.
- A. FSH stimulates estrogen secretion by ovarian cells; therefore it is not synthesized by males.
- B. The physician is wronga hormone made in the adenohypophysis could not influence fertility.
- C. FSH stimulates sperm production in the testes.
- D. The man must be producing progesterone, which inhibits the synthesis of FSH.
Correct Answer: C
Rationale: Step 1: Follicle-stimulating hormone (FSH) is essential for sperm production in males.
Step 2: FSH is produced in the anterior pituitary gland.
Step 3: In males, FSH stimulates the Sertoli cells in the testes to support sperm production.
Step 4: Therefore, if a man is not synthesizing enough FSH, it can lead to reduced sperm production and fertility issues.
Summary:
A: Incorrect - FSH is synthesized by males in the anterior pituitary gland, not just females for estrogen secretion.
B: Incorrect - Hormones produced in the adenohypophysis, like FSH, play a crucial role in fertility.
D: Incorrect - Progesterone does not inhibit the synthesis of FSH; it is involved in the female reproductive system, not male fertility.
The endocrine gland(s) that sits on top of the kidneys and secretes both metabolic stabilizers and stress regulators:
- A. pancreas
- B. adrenal glands
- C. thyroid gland
- D. pituitary gland
Correct Answer: B
Rationale: The correct answer is B: adrenal glands. The adrenal glands are located on top of the kidneys and secrete hormones like cortisol and adrenaline, which play a key role in regulating metabolism and responding to stress. The pancreas (A) primarily regulates blood sugar levels. The thyroid gland (C) regulates metabolism and growth. The pituitary gland (D) controls several other endocrine glands but is not located on top of the kidneys and does not secrete metabolic stabilizers and stress regulators.
This is Not a Function of Insulin
- A. Decreasing glycogenolysis
- B. Lipogenesis
- C. Gluconeogenesis
- D. Glycogenesis
Correct Answer: C
Rationale: The correct answer is C: Gluconeogenesis is not a function of insulin. Insulin's main role is to lower blood glucose levels by promoting glucose uptake and storage. Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources, such as amino acids and glycerol, to increase blood glucose levels. Insulin inhibits gluconeogenesis by suppressing the enzymes involved in this process. Choices A, B, and D are all functions of insulin: A) Decreasing glycogenolysis - insulin promotes glycogen synthesis by inhibiting glycogen breakdown, B) Lipogenesis - insulin enhances the conversion of excess glucose into fatty acids for storage, and D) Glycogenesis - insulin increases the formation of glycogen from glucose for storage.
Which of the following is not a function of insulin?
- A. Lowering blood glucose levels
- B. Promoting protein synthesis
- C. Simulating hepatic gluconeogenesis
- D. Promoting fatty acid synthesis
Correct Answer: C
Rationale: The correct answer is C: Stimulating hepatic gluconeogenesis. Insulin's primary function is to lower blood glucose levels by promoting glucose uptake in cells and inhibiting gluconeogenesis in the liver. Choice A is correct as insulin helps lower blood glucose levels. Choice B is correct as insulin promotes protein synthesis. Choice D is correct as insulin promotes fatty acid synthesis to store excess glucose as fat. Therefore, choice C is incorrect as insulin actually inhibits hepatic gluconeogenesis rather than stimulating it.
