Which of the following structures is responsible for the production of digestive enzymes and bicarbonate-rich pancreatic juice?
- A. Liver
- B. Gallbladder
- C. Pancreas
- D. Spleen
Correct Answer: C
Rationale: The correct answer is C: Pancreas. The pancreas is responsible for producing digestive enzymes and bicarbonate-rich pancreatic juice. It secretes enzymes like amylase, lipase, and protease to break down carbohydrates, fats, and proteins in the small intestine. The bicarbonate-rich juice helps neutralize stomach acid. The liver (A) produces bile stored in the gallbladder (B), which aids in fat digestion. The spleen (D) is involved in immune function and blood filtration, not digestive enzyme production.

A patient presents with excessive thirst, large volumes of dilute urine, and low urine osmolality. Laboratory tests reveal hypernatremia and elevated serum osmolality. Which endocrine disorder is most likely responsible for these symptoms?
- A. Hyperthyroidism
- B. Hypothyroidism
- C. Diabetes mellitus
- D. Diabetes insipidus
Correct Answer: D
Rationale: The correct answer is D: Diabetes insipidus. This condition is characterized by excessive thirst, large volumes of dilute urine, low urine osmolality, hypernatremia, and elevated serum osmolality. The underlying cause is a deficiency in or insensitivity to antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Hyperthyroidism (choice A) and hypothyroidism (choice B) do not directly affect urine concentration. While diabetes mellitus (choice C) can also present with polyuria and polydipsia, it would typically have high urine osmolality due to the presence of glucose. Therefore, diabetes insipidus is the most likely endocrine disorder responsible for these specific symptoms.
A patient presents with chronic nasal congestion, hyposmia, and anosmia. Nasal endoscopy reveals polypoid masses obstructing the nasal cavity and sinuses. Which of the following conditions is most likely responsible for this presentation?
- A. Allergic rhinitis
- B. Chronic sinusitis
- C. Nasal polyps
- D. Deviated nasal septum
Correct Answer: C
Rationale: The correct answer is C: Nasal polyps. Nasal polyps are benign growths that form in the nasal cavity and sinuses, leading to symptoms such as chronic nasal congestion, hyposmia, and anosmia. The presence of polypoid masses seen on nasal endoscopy is characteristic of nasal polyps.
Rationale:
1. Chronic nasal congestion, hyposmia, and anosmia are common symptoms of nasal polyps.
2. Nasal endoscopy revealing polypoid masses confirms the presence of nasal polyps.
3. Allergic rhinitis may cause nasal congestion but does not typically present with polypoid masses.
4. Chronic sinusitis can cause nasal congestion but is usually associated with inflammation of the sinuses, not just polypoid masses.
5. A deviated nasal septum can lead to nasal congestion but does not typically cause polypoid masses obstructing the nasal cavity and sinuses.
