Correct Answer: B

Rationale: The correct answer is B: Acute myocardial infarction (MI) is the most common cause of cardiogenic shock. During an MI, there is significant damage to the heart muscle, leading to a decrease in cardiac output and subsequent shock. This results in inadequate tissue perfusion and oxygen delivery. Choices A, C, and D are incorrect because decreased hemoglobin level (A) may lead to anemia but is not the most common cause of cardiogenic shock. Hypotension (C) is a symptom of shock, not the cause. Coronary artery disease (D) is a risk factor for MI but not the direct cause of cardiogenic shock.

Correct Answer: D

Rationale: The correct answer is D because the licensure examination aims to assess if candidates meet the expected competency standards to practice nursing safely and effectively. This process ensures that only qualified individuals enter the profession, maintaining high standards of care. Choice A is incorrect because the exam goes beyond applying theory to include practical skills. Choice B is incorrect as protecting the public is the outcome of ensuring competency. Choice C is incorrect as the exam evaluates the full scope of nursing practice, not just its application.

Correct Answer: A

Rationale: The correct answer is A: Rotator cuff tear. The presentation of acute shoulder pain and limited range of motion after a fall onto an outstretched hand, along with tenderness over the greater tuberosity and pain with passive abduction and external rotation, is classic for a rotator cuff tear. The mechanism of injury and physical exam findings are consistent with this condition. B: Glenohumeral dislocation typically presents with a visibly deformed shoulder and loss of normal shoulder contour. C: Acromioclavicular joint separation would present with tenderness over the AC joint rather than the greater tuberosity, and typically involves a history of direct trauma to the shoulder. D: Proximal humerus fracture would present with more diffuse shoulder pain and swelling, and not specific tenderness over the greater tuberosity.

Correct Answer: D

Rationale: The correct answer is D: Diabetic retinopathy. This condition is a common complication of diabetes that occurs due to the thickening of capillaries and arterioles in the eye, leading to damage to the retina. This can result in vision problems and even blindness if left untreated. A: Papilledema is the swelling of the optic disc due to increased intracranial pressure, not related to diabetes. B: Glaucoma is a condition characterized by increased pressure within the eye, not directly caused by diabetes. C: Retinal detachment is the separation of the retina from the underlying tissues, which is not primarily caused by diabetes-related capillary changes.

Correct Answer: C

Rationale: The correct answer is C: Hyponatremia. SSRI medications can lead to the syndrome of inappropriate antidiuretic hormone secretion (SIADH), causing hyponatremia. This occurs due to increased levels of serotonin affecting the hypothalamus, leading to excessive ADH release. Hyponatremia can result in neurological symptoms and must be closely monitored. A: Bradycardia is not a common adverse effect of SSRIs. B: Hyperkalemia is not typically associated with SSRIs. D: Hypertension is not a common adverse effect of SSRIs; they may actually lower blood pressure.
