A total obstruction of the airway by aspirated material is manifested by:
Hoarse cough
Rapid loss of consciousness
Inflammation of the mucosa
Dyspnea
The Correct Answer is B
A. A hoarse cough may occur with partial airway obstruction, but it is not a typical sign of a complete obstruction. A total obstruction would more likely lead to inability to cough effectively.
B. A total obstruction of the airway, such as from aspirated material, can lead to rapid loss of consciousness due to the lack of oxygen reaching the brain. This is a critical emergency.
C. Inflammation of the mucosa is a response to irritation or injury but would not be the primary manifestation of a total airway obstruction.
D. Dyspnea (difficulty breathing) is common with airway obstructions, but in the case of total obstruction, the person would be unable to breathe at all, leading to more severe signs like loss of consciousness.

Correct Answer is D
Explanation
A. Osteoclasts are responsible for bone resorption, not formation. Increased osteoclast activity leads to excessive bone breakdown, not enhanced formation.
B. Osteoblasts are responsible for bone formation. In osteoporosis, osteoblast activity is not increased; rather, it is osteoclast activity that is dysregulated, leading to bone loss.
C. Enhanced bone formation is typically seen in conditions like osteopetrosis or during bone healing. Osteoporosis is characterized by an imbalance in favor of bone resorption, not formation.
D. Osteoporosis is characterized by increased bone resorption, which is primarily driven by osteoclast activity. This leads to a decrease in bone density and an increased risk of fractures.
Correct Answer is C
Explanation
A. Weakness, vomiting, hypotension, and mental confusion may occur in cases of diabetic ketoacidosis (DKA), but these are more acute signs of severe complications rather than early symptoms of type 1 diabetes.
B. Vomiting, abdominal pain, sweet fruity breath, dehydration, and Kussmaul breathing are signs of diabetic ketoacidosis (DKA), a serious complication that typically develops after the onset of type 1 diabetes, not early symptoms.
C. Polydipsia (excessive thirst), polyuria (frequent urination), polyphagia (excessive hunger), weight loss, and fatigue are classic early signs and symptoms of type 1 diabetes due to the body's inability to regulate blood glucose levels properly.
D. Recurrent infections, visual changes, and paresthesia (numbness or tingling) are typically associated with long-term, poorly controlled diabetes, not early signs of type 1 diabetes.
