General MedicineBradycardia is seen in all mentioned conditions: myxoedema (hypothyroidism causes decreased metabolic rate), obstructive jaundice (increased intracranial pressure effect), and head injuries (increased intracranial pressure causing Cushing reflex with bradycardia and hypertension).

In a patient with a suspected STEMI, the characteristic ECG findings include ST elevation in the anterolateral leads (I, aVL, V1-V6) and reciprocal ST depression in the inferior leads (II, III, aVF). The pattern of ST elevation in the anterolateral leads with reciprocal depression in the inferior leads is most indicative of a STEMI affecting the anterolateral wall of the heart.

The history of alcoholism and symptoms of fever, abdominal pain, and elevated WBC count are more consistent with pancreatitis, which is commonly associated with alcohol abuse.

Physiology
The rate of gastric emptying is influenced by the type and amount of food consumed. In healthy individuals, it typically takes 1-4 hours for the stomach to empty its contents into the duodenum. The rate of emptying can be slower with high-fiber or high-fat meals and faster with liquids. Factors such as gastric motility, the presence of gastric emptying hormones, and the presence of food in the intestine also play a role in this process.

Physiology
Answer: 4) Decreasing heart rate and promoting gastrointestinal activity
Explanation: The parasympathetic nervous system is responsible for the "rest and digest" functions. It slows the heart rate, constricts pupils, and stimulates digestive processes such as increased salivation, gastric acid secretion, and gastrointestinal motility.

Physiology
The physiological capacity of the bladder is the maximum intravesical volume tolerated without undue discomfort. It is usually between 250 and 450 ml. The bladder can stretch to hold more urine, but this is considered beyond the normal physiological capacity and can cause discomfort.

Oral PathologyScleroderma (systemic sclerosis) does NOT cause widening of the oral aperture. Instead, it causes NARROWING (microstomia) of the oral aperture due to perioral fibrosis and skin tightening. Scleroderma does cause a hard, rigid tongue due to collagen deposition, pseudoankylosis of TMJ due to fibrosis, and difficulty swallowing (dysphagia) due to esophageal involvement.
