1. What is the purpose of the cuff in a Tracheostomy tube?

A. Separate the upper and lower airway
B. Separate trachea from the esophagus
C. Separate the larynx from the nasopharynx
D. Secure the placement of the tube

Correct answer: B

Rationale: The purpose of the cuff in a Tracheostomy tube is to separate the trachea from the esophagus. The cuff helps prevent aspiration by creating a seal that separates the trachea from the esophagus, reducing the risk of food or fluids entering the lungs. Choices A, C, and D are incorrect because the cuff's primary function in a Tracheostomy tube is to prevent aspiration rather than separating the upper and lower airway, larynx from the nasopharynx, or securing the placement of the tube.

2. What is a common symptom of vitamin D deficiency?

A. Hair loss
B. Night blindness
C. Bone pain
D. Rashes

Correct answer: C

Rationale: The correct answer is C: Bone pain. Vitamin D deficiency often leads to bone pain and weakness as it plays a crucial role in maintaining bone health by aiding in the absorption of calcium. Hair loss (choice A) is not a common symptom of vitamin D deficiency. Night blindness (choice B) is typically associated with vitamin A deficiency, not vitamin D deficiency. Rashes (choice D) are not a common symptom of vitamin D deficiency.

A. 70-80 years
B. 75-84 years
C. 80-90 years
D. 85 years or older

Correct answer: D

Rationale: The 'oldest old' category includes adults aged 85 years or older. This age group faces unique health challenges and requires specialized care. Choices A, B, and C are incorrect as they do not fall within the age range specified for the 'oldest old' category.

4. Which organ produces and secretes bicarbonate ions and insulin?

A. Stomach
B. Pancreas
C. Large intestine
D. Small intestine

Correct answer: B

Rationale: The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.
