This Hormone is Not Secreted by Hypothalamus
- A. PRH
- B. FSH
- C. CRH
- D. TRH
Correct Answer: B
Rationale: Correct Answer: B (FSH)
Rationale:
1. FSH (Follicle Stimulating Hormone) is secreted by the anterior pituitary gland, not the hypothalamus.
2. PRH (Prolactin Releasing Hormone), CRH (Corticotropin Releasing Hormone), and TRH (Thyrotropin Releasing Hormone) are all hormones secreted by the hypothalamus, involved in regulating pituitary hormone release.
3. Therefore, FSH is the correct answer as it is not directly secreted by the hypothalamus.
Summary:
- FSH is secreted by the anterior pituitary gland, not the hypothalamus.
- PRH, CRH, and TRH are hormones secreted by the hypothalamus.
- Understanding the origin of each hormone helps in determining the correct answer.

What is the formula of aluminium sulfate?
- A. Al2(SO4)3
- B. Al2(SO3)4
- C. Al4(SO4)2
- D. Al4(SO3)2
Correct Answer: A
Rationale: The correct formula for aluminium sulfate is Al2(SO4)3. This is because aluminium has a 3+ charge while sulfate has a 2- charge, requiring two aluminium ions to balance three sulfate ions. Choice B (Al2(SO3)4) is incorrect because sulfate ions have a 2- charge, not sulfite ions (SO3). Choices C (Al4(SO4)2) and D (Al4(SO3)2) have incorrect subscripts for the elements, not following the correct charge balance.
Hypocalcemic tetany:
- A. causes a flaccid paralysis.
- B. resembles neuromuscular blockade by curare.
- C. may be caused by a deficiency of PTH.
- D. is caused by a deficiency of insulin.
Correct Answer: C
Rationale: Step-by-step rationale:
1. Hypocalcemic tetany is associated with low levels of calcium in the blood.
2. Parathyroid hormone (PTH) plays a crucial role in calcium regulation.
3. A deficiency of PTH can lead to decreased calcium levels, causing tetany.
4. Therefore, choice C is correct as hypocalcemic tetany may be caused by a deficiency of PTH.
Summary:
A: Incorrect. Hypocalcemic tetany leads to muscle spasms, not flaccid paralysis.
B: Incorrect. Curare blockade affects neuromuscular transmission, not calcium levels.
D: Incorrect. Insulin deficiency is associated with hyperglycemia, not hypocalcemia leading to tetany.
The chemical classification of hormones does NOT include __________.
- A. glucose-containing hormones
- B. steroid hormones
- C. protein-based hormones
- D. amino acid-based hormones
Correct Answer: A
Rationale: The correct answer is A: glucose-containing hormones. Hormones are classified based on their chemical structure, and glucose-containing hormones do not fit into any of the main categories (steroid, protein-based, amino acid-based). Glucose is a sugar molecule and not typically found as the primary chemical structure of hormones. Steroid hormones are derived from cholesterol, protein-based hormones are made of amino acids, and amino acid-based hormones are derived from single amino acids or peptides. Therefore, glucose-containing hormones do not align with the traditional chemical classifications of hormones.
A nurse teaches an older woman who has a decreased production of estrogen. Which statement would the nurse include in this client’s teaching to decrease injury?
- A. Drink at least 2 quarts (2 L) of fluids each day.
- B. Walk around the neighborhood for daily exercise.
- C. Bathe your perineal area twice a day.
- D. You should check your blood glucose before meals.
Correct Answer: B
Rationale: The correct answer is B. Daily exercise, such as walking, helps improve bone density and strength, reducing the risk of falls and fractures in older women with decreased estrogen production. Walking also helps maintain muscle strength and balance.
A: Drinking fluids is important for overall health but does not directly address decreasing injury in this scenario.
C: Bathing the perineal area twice a day is important for hygiene but does not specifically address decreasing injury.
D: Checking blood glucose levels is important for diabetes management but is not directly related to decreasing injury in this case.
Mr. Johnson received his first dose of Lente insulin at 7:30 A.M. When should he be observed for signs of hypoglycemia?
- A. 10-11 A.M.
- B. 4-6 P.M.
- C. Between 2 A.M. and breakfast
- D. Immediately after the injection
Correct Answer: B
Rationale: Lente insulin has an onset of action that typically peaks 4-6 hours after injection, so this is when signs of hypoglycemia are most likely to occur.
