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. Identifying specific pathogens is important for guiding treatment, but the immediate focus in septic shock is on supporting circulation and treating the source of infection rather than just identification.
B. Improving tissue perfusion through intravenous fluid and blood replacement is part of the treatment but is not the sole focus. It is a supportive measure, and it is done alongside treating the source of infection.
C. Administering antibiotics is critical in septic shock but is only part of the treatment. It should be done alongside efforts to support circulation and treat the source of infection.
D. Treating the source of infection and supporting circulation are the primary goals in managing septic shock. This includes administering fluids, antibiotics, and sometimes vasopressors, in addition to addressing the underlying infection.
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.
