What do the following hormones have in common: growth hormone, cortisol, and epinephrine? All:

  • A. are secreted by the adrenal glands.
  • B. raise blood glucose.
  • C. suppress gluconeogenesis.
  • D. are steroids.
Correct Answer: B

Rationale: Step-by-step rationale for why choice B is correct:
1. Growth hormone, cortisol, and epinephrine all raise blood glucose levels.
2. Growth hormone promotes glucose production, cortisol increases blood sugar through gluconeogenesis, and epinephrine stimulates glycogen breakdown.
3. The increase in blood glucose is essential for providing energy during stress or physical activity.
4. None of the other choices align with all three hormones' functions, making choice B the correct answer.
Summary: Choices A and D are incorrect because not all three hormones are secreted by the adrenal glands or are steroids. Choice C is incorrect as these hormones do not suppress gluconeogenesis; instead, they promote processes that raise blood glucose levels.

What is the total cost of using the heater for 15 minutes?

  • A. $0.04
  • B. $0.15
  • C. $2.40
  • D. $9.00
Correct Answer: B

Rationale: To calculate the total cost of using the heater for 15 minutes, we need to consider the cost per minute. If the cost is $0.01 per minute, then for 15 minutes, it would be 15 * $0.01 = $0.15. Therefore, the correct answer is B.

Option A ($0.04) is incorrect because it is too low for 15 minutes of usage. Option C ($2.40) and Option D ($9.00) are incorrect because they are too high for the given time frame.

For the patient with pheochromocytoma, what physical assessment technique should you instruct the LPN/LVN to avoid?

  • A. Palpation of the abdomen
  • B. Auscultation of lung sounds
  • C. Inspection of the skin for lesions
  • D. Checking the peripheral pulses
Correct Answer: A

Rationale: Palpation of the abdomen should be avoided in patients with pheochromocytoma, as it can trigger the release of catecholamines and cause a hypertensive crisis.

Which group is incorrect?

  • A. Hormones of the anterior pituitary gland: ACTH, prolactin, TSH, oxytocin
  • B. Steroids: cortisol, aldosterone, testosterone
  • C. Secretions of the gonads: estrogen, progesterone, testosterone
  • D. Hormones secreted by the thyroid gland: T3, T4, calcitonin
Correct Answer: A

Rationale: The correct answer is A because oxytocin is not a hormone of the anterior pituitary gland; it is produced in the hypothalamus and stored in the posterior pituitary. ACTH, prolactin, and TSH are indeed hormones secreted by the anterior pituitary gland.

Choice B is incorrect because cortisol and aldosterone are steroid hormones produced by the adrenal glands, not the gonads. Testosterone is a hormone produced by the gonads.

Choice C is correct as estrogen, progesterone, and testosterone are indeed secretions of the gonads - estrogen and progesterone from the ovaries and testosterone from the testes.

Choice D is incorrect because calcitonin is a hormone secreted by the thyroid gland, but T3 and T4 are thyroid hormones, not hormones secreted by the thyroid gland.

An autoimmune form of hypothyroidism when the body destroys the thyroid cells is called

  • A. Hashimoto's disease.
  • B. Graves disease.
  • C. myxedema.
  • D. acromegaly
Correct Answer: A

Rationale: Rationale:
1. Hashimoto's disease is characterized by the immune system attacking the thyroid gland, leading to hypothyroidism.
2. It is an autoimmune condition where the body produces antibodies that target and destroy thyroid cells.
3. This results in a decrease in thyroid hormone production.
4. Graves disease (choice B) is a form of hyperthyroidism caused by an overactive thyroid gland.
5. Myxedema (choice C) refers to severe hypothyroidism but is not autoimmune.
6. Acromegaly (choice D) is a disorder caused by excess growth hormone production, unrelated to thyroid function.

Mrs. Good, a diabetic, states that she has taken the oral hypoglycemic, phenformin hydrochloride (DBI), for years. From this information, the nurse knows that Mrs. Good

  • A. has not been receiving close medical supervision
  • B. has moderately severe diabetes
  • C. has active beta-cell function
  • D. will soon need to switch to insulin therapy
Correct Answer: A

Rationale: Phenformin has been largely discontinued due to safety concerns, and it suggests the patient may not be receiving proper diabetes management.
