Which of the following arteries supply the tail of pancreas?
- A. Inferior pancreaticoduodenal
- B. Left gastroepiploic artery
- C. Splenic artery
- D. Superior pancreaticoduodenal
Correct Answer: C
Rationale: The correct answer is C: Splenic artery. The splenic artery supplies the tail of the pancreas through its branches. The splenic artery runs along the superior border of the pancreas and gives off multiple branches that supply various parts of the pancreas, including the tail.
A: Inferior pancreaticoduodenal artery supplies the inferior part of the pancreas.
B: Left gastroepiploic artery supplies the greater curvature of the stomach.
D: Superior pancreaticoduodenal artery supplies the pancreatic head and duodenum.
Therefore, the splenic artery is the correct answer as it specifically supplies the tail of the pancreas.

When caring for a diabetic client at night, the only symptom of insulin shock that a nurse might observe is
- A. dry mucous membranes
- B. acetone breath
- C. flushed appearance
- D. diaphoresis
Correct Answer: D
Rationale: The most common symptom of insulin shock or hypoglycemia is diaphoresis (sweating), which is a result of the body's stress response to low blood glucose levels.
The target organs of ADH are the:
- A. adrenal cortex and liver
- B. kidney and blood vessels
- C. liver and kidney
- D. pituitary and thyroid glands
Correct Answer: B
Rationale: The correct answer is B: kidney and blood vessels. ADH, or antidiuretic hormone, acts on the kidney to regulate water reabsorption and maintain fluid balance in the body. It also acts on blood vessels to regulate blood pressure. The other choices are incorrect because ADH does not target the adrenal cortex, liver, pituitary gland, or thyroid gland specifically for its primary functions. ADH primarily acts on the kidney and blood vessels to regulate water balance and blood pressure in the body.
One of the two hormones made by the pituitary that help regulate reproductive cells is luteinizing hormone. The other hormone is .
- A. follicle-stimulating hormone
- B. epinephrine
- C. norepinephrine
- D. androgens
Correct Answer: A
Rationale: The correct answer is A: follicle-stimulating hormone (FSH). FSH is the other hormone made by the pituitary gland that helps regulate reproductive cells, along with luteinizing hormone (LH). FSH is responsible for stimulating the growth and maturation of ovarian follicles in females and spermatogenesis in males.
Explanation:
1. FSH is directly involved in the reproductive process by stimulating follicle development and sperm production.
2. Epinephrine and norepinephrine are not hormones produced by the pituitary gland and are involved in the stress response.
3. Androgens are male sex hormones produced primarily by the testes, not the pituitary gland.
In summary, FSH is the correct answer as it plays a crucial role in regulating reproductive cells, while the other choices are not involved in the reproductive system or are not produced by the pituitary gland.
The neurohypophysis:
- A. is the anterior pituitary gland.
- B. secretes ACTH, TSH, and the gonadotropins.
- C. secretes the releasing hormones.
- D. is the posterior pituitary gland.
Correct Answer: D
Rationale: Step-by-step rationale:
1. The neurohypophysis is the posterior pituitary gland.
2. It stores and releases hormones produced by the hypothalamus.
3. These hormones include oxytocin and vasopressin.
4. These hormones regulate water balance, blood pressure, and uterine contractions.
5. Choice D is correct as it accurately describes the neurohypophysis.
Summary:
A: Incorrect - Anterior pituitary gland is not the neurohypophysis.
B: Incorrect - These hormones are secreted by the anterior pituitary gland.
C: Incorrect - Releasing hormones are produced by the hypothalamus, not the neurohypophysis.
The secretion of parathyroid hormone is a good example of __________.
- A. pituitary gland stimuli
- B. humoral stimuli
- C. neural stimuli
- D. hormonal stimuli
Correct Answer: B
Rationale: The correct answer is B: humoral stimuli. Parathyroid hormone secretion is regulated by the concentration of calcium in the blood, which is an example of humoral stimuli. When blood calcium levels decrease, parathyroid hormone is released to increase calcium levels. Pituitary gland stimuli (A), neural stimuli (C), and hormonal stimuli (D) are not directly involved in the regulation of parathyroid hormone secretion.
