1. What does "IDDM" stand for in the context of diabetes?
IDDM stands for Insulin-Dependent Diabetes Mellitus, which is an older term for Type 1 Diabetes. This condition is characterized by the body's inability to produce insulin, a hormone necessary for glucose uptake by cells. Individuals with IDDM require daily insulin injections to manage their blood sugar levels.
2. Which type of patients might require continuous positive airway pressure (CPAP)?
CPAP is commonly used to treat sleep apnea by providing continuous airflow to keep the airway open.
3. Which medication is used to treat methemoglobinemia in patients with toxic oxygen levels?
Methylene blue reduces methemoglobin back to functional hemoglobin by acting as an electron donor via the NADPH-dependent pathway.
4. What is the primary purpose of mechanical ventilation?
Mechanical ventilation assists patients who are unable to breathe effectively on their own.
5. What is the recommended head-of-bed elevation to reduce ventilator-associated pneumonia (VAP) risk?
Elevating the head of bed 30–45 degrees reduces aspiration of gastric contents and oropharyngeal secretions, decreasing VAP risk.
6. The Modified Medical Research Council (mMRC) dyspnea scale is specifically used to:
