Which gland secretes melatonin and is concerned with our biological rhythms?

  • A. Pancreas
  • B. Adenohypophysis
  • C. Pineal gland
  • D. Adrenal gland
Correct Answer: C

Rationale: The correct answer is C: Pineal gland. The pineal gland is responsible for secreting melatonin, a hormone that regulates our biological rhythms such as sleep-wake cycles. This gland is located in the brain and plays a crucial role in maintaining our circadian rhythm. The other choices are incorrect because:
A: The pancreas secretes insulin and glucagon to regulate blood sugar levels, not melatonin.
B: The adenohypophysis, or anterior pituitary gland, secretes various hormones but not melatonin.
D: The adrenal gland produces hormones like cortisol and adrenaline, not melatonin.

  • C. Call for an ambulance to transport the patient to a medical facility.
  • D. Administer glucagon 1 mg intramuscularly (IM) or subcutaneously.

After a thyroidectomy, Mr. M begins to show signs of tetany. The nurse should suspect a deficiency of which of the following?

  • A. Insulin
  • B. Parathyroid hormone

From where is the hormone glucagon secreted?

  • A. F cells of the islets of Langerhans
  • B. β-Cells of the islets of Langerhans
  • C. α-Cells of the islets of Langerhans
  • D. Delta cells of the islets of Langerhans
Correct Answer: C

Rationale: Glucagon is secreted by the α-cells of the islets of Langerhans in the pancreas, helping to raise blood glucose levels.

In relation to noradrenaline, all of the following are true EXCEPT:

  • A. It stimulates α and β receptors
  • B. It decreases heart rate
  • C. It decreases blood pressure
  • D. Causes vasoconstriction
Correct Answer: C

Rationale: Rationale:
- Noradrenaline stimulates both α and β receptors, leading to increased heart rate and vasoconstriction.
- It does not decrease heart rate; it actually increases heart rate due to its actions on β receptors.
- Noradrenaline causes vasoconstriction by activating α receptors, leading to increased blood pressure.
- The incorrect statement is C, as noradrenaline actually increases blood pressure by causing vasoconstriction.
