Correct Answer: B

Rationale: The correct answer is B: Psoriasis. Psoriasis is characterized by pruritic, erythematous patches with silvery scales, commonly found on the elbows, knees, and scalp. This presentation matches the patient's symptoms. Eczema (choice A) typically presents with red, inflamed, and itchy skin patches. Pityriasis rosea (choice C) manifests as a herald patch followed by smaller scaly patches in a "Christmas tree" distribution. Seborrheic dermatitis (choice D) involves oily, yellowish, scaly patches mainly on the scalp, face, and ears, and does not typically present with silvery scales.

Correct Answer: B

Rationale: The correct answer is B: 20-Gauge. The smaller the gauge number, the larger the diameter of the catheter. Blood transfusions typically require a larger catheter size to prevent hemolysis and ensure proper flow. A 20-Gauge catheter is larger than 22-Gauge, 18-Gauge, and 12-Gauge, making it suitable for administering blood. 22-Gauge is too small and can cause hemolysis, 18-Gauge is smaller than the recommended size for blood transfusions, and 12-Gauge is too large and can cause damage to the vein.

Correct Answer: C

Rationale: The correct answer is C: Pancreas. The pancreas is responsible for producing digestive enzymes and bicarbonate-rich pancreatic juice. It secretes enzymes like amylase, lipase, and protease to break down carbohydrates, fats, and proteins in the small intestine. The bicarbonate-rich juice helps neutralize stomach acid. The liver (A) produces bile stored in the gallbladder (B), which aids in fat digestion. The spleen (D) is involved in immune function and blood filtration, not digestive enzyme production.

Correct Answer: D

Rationale: The correct answer is D: Trigeminal neuralgia. This condition is characterized by recurrent, severe, stabbing pain in the trigeminal nerve distribution triggered by touch, chewing, or cold exposure. The key feature is the characteristic lancinating pain, which is not typical of migraine (choice A), cluster headache (choice B), or tension-type headache (choice C). Migraine typically presents with pulsating, moderate to severe headache associated with nausea and sensitivity to light and sound. Cluster headache is characterized by severe, unilateral pain around the eye associated with autonomic symptoms. Tension-type headache presents with bilateral, pressing or tightening pain without specific triggers. Therefore, based on the description of the symptoms in the question, trigeminal neuralgia is the most likely diagnosis.

Correct Answer: A

Rationale: The correct answer is A: Initiate non-invasive positive pressure ventilation (NIPPV). This intervention is prioritized as it helps improve oxygenation and ventilation in COPD exacerbation without the need for invasive mechanical ventilation, reducing the risk of ventilator-associated complications. NIPPV also decreases the work of breathing and can prevent the need for intubation. Administering bronchodilator medications (B) is important in COPD exacerbation but may not address the immediate need for ventilatory support. Endotracheal intubation (C) should be reserved for cases of respiratory failure not responding to NIPPV. Chest physiotherapy (D) may be beneficial in some cases but is not the first-line intervention for managing acute COPD exacerbation.
