As a precaution for vocal cord paralysis from damage to the recurrent laryngeal nerve during thyroidectomy surgery, what equipment should be in the room in case it is needed for this emergency situation?
- A. Tracheostomy tray
- B. IV calcium gluconate
- C. Oxygen equipment
- D. Paper and pencil for communication
Correct Answer: A
Rationale: A tracheostomy tray should be readily available in case of airway obstruction due to vocal cord paralysis following thyroid surgery.

Which of the following agents might mask the hypoglycemic reaction in treated diabetic patients?
- A. Beta-adrenergic agonists
- B. Alpha-adrenergic antagonists
- C. Alpha-adrenergic agonists
- D. Beta-adrenergic antagonists
Correct Answer: D
Rationale: The correct answer is D: Beta-adrenergic antagonists. Beta-blockers can mask the typical signs and symptoms of hypoglycemia such as tremors, palpitations, and sweating by inhibiting the adrenergic response to low blood sugar levels. Other choices (A, B, C) are incorrect as they do not have the same mechanism of action in masking hypoglycemic reactions in diabetic patients.
All of the following are hormones of the anterior pituitary except:
- A. Human growth hormone (GH).
- B. Follicle-stimulating hormone (FSH).
- C. Parathyroid hormone(PTH).
- D. Thyroid-stimulating hormone (TSH).
Correct Answer: C
Rationale: The correct answer is C: Parathyroid hormone (PTH). The anterior pituitary gland secretes hormones that regulate various bodily functions, such as growth, reproduction, and metabolism. PTH is actually produced by the parathyroid glands, not the anterior pituitary. Human growth hormone (GH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH) are all hormones secreted by the anterior pituitary gland. Therefore, C is the correct answer as it is not a hormone produced by the anterior pituitary gland.
Insulin:
- A. binds to GLUT 1-5 receptors in the peripheral tissues
- B. deficiency results in increased gluconeogenesis
- C. has a plasma half-life of 2-3 hours
- D. is secreted by the pancreatic A cells
Correct Answer: B
Rationale: The correct answer is B because insulin deficiency leads to increased gluconeogenesis due to the lack of inhibition on glucose production. Choice A is incorrect as insulin binds to GLUT 4 receptors, not GLUT 1-5. Choice C is wrong because insulin's half-life is only a few minutes. Choice D is also inaccurate as insulin is secreted by pancreatic beta cells, not A cells.
Identify the hormone that causes the development of the breast and milk production.
- A. oxytocin
- B. prolactin
- C. estrogen
- D. antidiuretic hormone
Correct Answer: B
Rationale: The correct answer is B: prolactin. Prolactin is the hormone responsible for the development of the breast tissue and milk production in females. It is secreted by the anterior pituitary gland and plays a key role in lactation. Oxytocin is involved in milk ejection, not breast development. Estrogen plays a role in breast development but not specifically in milk production. Antidiuretic hormone regulates water balance and has no direct role in breast development or milk production.
Which row describes aqueous sodium chloride in process 1 and the name of process 2?
- A. residue, evaporation
- B. residue, filtration
- C. filtrate, evaporation
- D. filtrate, filtration
Correct Answer: C
Rationale: The correct answer is C: filtrate, evaporation. In process 1, aqueous sodium chloride would form the filtrate after filtration, as the solid residue is left behind. In process 2, evaporation is used to separate the solvent (water) from the dissolved salt, leaving behind the pure salt. Choice A is incorrect because residue is the solid left behind, not the liquid portion (filtrate). Choice B is incorrect as filtration results in the filtrate, not the residue. Choice D is incorrect as the filtrate undergoes evaporation, not filtration.
