✍️ Sample COMSAE Questions & Answers
1. Which electrolyte abnormality is the most immediately life-threatening complication of acute renal failure requiring emergent treatment?
Hyperkalemia is the most immediately dangerous complication of acute renal failure because it can cause fatal cardiac arrhythmias including ventricular fibrillation.
2. Which cranial nerve is responsible for motor innervation to the muscles of mastication?
The Trigeminal nerve (CN V) is responsible for motor innervation to the muscles of mastication (chewing). Specifically, the mandibular branch (V3) of the trigeminal nerve innervates muscles such as the masseter, temporalis, and pterygoids. It also provides sensory innervation to the face, but its motor component is critical for jaw movement.
3. A 30-year-old man presents with recurrent hematuria coinciding with upper respiratory infections (synpharyngitic hematuria). Kidney biopsy shows mesangial IgA deposits. What is the diagnosis?
IgA nephropathy (Berger disease) is characterized by mesangial IgA immune complex deposition, presenting with gross hematuria during mucosal infections (within 1-2 days).
4. What is the primary function of mitochondria in eukaryotic cells?
Mitochondria are often referred to as the 'powerhouses' of the cell because their primary function is energy production. Through cellular respiration, they generate adenosine triphosphate (ATP), the main energy currency of the cell, from glucose and other fuel molecules. This process is crucial for nearly all cellular activities requiring energy.
5. Which of the following techniques is a direct osteopathic manipulative treatment?
High-velocity, low-amplitude (HVLA) thrust is a direct osteopathic manipulative treatment technique. Direct techniques involve moving the dysfunctional body part towards the restrictive barrier, engaging it, and then applying a corrective force. HVLA specifically uses a rapid, therapeutic force of brief duration that travels a short distance within the anatomic range of motion, often resulting in an audible 'pop' or 'click'.
6. Which of the following core tenets of osteopathic medicine best describes the principle that the human body has an inherent capacity to defend, repair, and heal itself?
The tenet that 'The body is capable of self-regulation, self-healing, and health maintenance' specifically articulates the osteopathic principle of the body's innate healing capacity. Osteopathic manipulative treatment (OMT) is often aimed at removing somatic barriers to allow this inherent capacity to function optimally. The other options are also core tenets but do not specifically address the self-healing mechanism.
