The hypothalamic-hypophyseal tract ________.
- A. connects the hypophysis to the pituitary gland
- B. is partly contained within the infundibulum
- C. conducts aldosterone to the hypophysis
- D. is the site of prolactin synthesis
Correct Answer: B
Rationale: The correct answer is B because the hypothalamic-hypophyseal tract is indeed partly contained within the infundibulum, which is a stalk-like structure connecting the hypothalamus to the pituitary gland. This pathway is crucial for the release of hormones from the hypothalamus to the pituitary gland. Choice A is incorrect as the hypophysis and pituitary gland are the same structure. Choice C is incorrect as aldosterone is a hormone produced by the adrenal glands, not related to the hypothalamic-pituitary axis. Choice D is incorrect because prolactin synthesis occurs in the lactotroph cells of the anterior pituitary, not in the hypothalamic-hypophyseal tract.

The nurse is assessing a client who exhibits spontaneous spasm of the fingers or toes, mouth twitching or jaw tightening when he taps the cheek anteriorly to the earlobe. What sign does the nurse identify to document in the chart that is consistent with tetany?
- A. Lhermitte's sign
- B. Trousseau's sign
- C. Chvostek's sign
- D. Bulge sign
Correct Answer: C
Rationale: Chvostek's sign is a positive sign of tetany, where tapping the cheek causes twitching of the facial muscles, indicating low calcium levels.
To prevent hyperglycemia or hypoglycemia related to exercise, what should the nurse teach the patient using glucose-lowering agents about the best time for exercise?
- A. Only after a 15-g carbohydrate snack is eaten
- B. About 1 hour after eating when blood glucose levels are rising
- C. When glucose monitoring reveals that the blood glucose is in the normal range
- D. When blood glucose levels are high, because exercise always has a hypoglycemic effect
Correct Answer: B
Rationale: Exercising about 1 hour after eating helps to ensure blood glucose is rising and reduces the risk of hypoglycemia.
To aid digestion the stomach produces?
- A. Alkali
- B. Trypsin
- C. Acid
- D. Amylase
Correct Answer: C
Rationale: The correct answer is C: Acid. The stomach produces hydrochloric acid to aid in digestion by creating an acidic environment that helps break down food and kill bacteria. Alkali (A) would not aid digestion as it neutralizes acids. Trypsin (B) and Amylase (D) are enzymes produced in the pancreas, not the stomach, and play a role in digesting proteins and carbohydrates, respectively. Thus, they are not the products of the stomach for aiding digestion.
Select the correct statement about the structure or function of chemical messengers.
- A. Prostaglandins are biologically active peptides.
- B. Modified cholesterol forms the main structural component of the peptone hormones.
- C. An amino acid derivative can be a hormone.
- D. An example of a paracrine is testosterone.
Correct Answer: C
Rationale: The correct answer is C: An amino acid derivative can be a hormone. This statement is correct because many hormones are derived from amino acids, such as thyroid hormones (derived from tyrosine) and epinephrine (derived from phenylalanine). Hormones can be derived from various sources, including amino acids, peptides, lipids, and even gases.
Explanation of other choices:
A: Prostaglandins are not biologically active peptides; they are lipid compounds derived from fatty acids.
B: Modified cholesterol does not form the main structural component of peptone hormones; peptides are the main structural components of peptide hormones.
D: Testosterone is a steroid hormone and not an example of a paracrine, which is a type of chemical messenger that acts on nearby cells.
A nurse is collecting data about the diet history of a client who has low blood sugar. Which of the following would be an important consideration in the diet history?
- A. Consumption of health foods
- B. Consumption of sea salt and kelp
- C. Consumption of seafood
- D. Consumption of carbohydrates
Correct Answer: D
Rationale: For clients with low blood sugar, it is important to assess their carbohydrate intake, as carbohydrates affect blood glucose levels.
