Correct Answer: C

Rationale: Chest pain, dyspnea, hypotension, and ST-segment elevation on an ECG in the inferior leads are classic signs of an acute myocardial infarction (MI). An acute MI occurs when there is a sudden blockage of blood flow to a part of the heart muscle, leading to tissue damage. This causes symptoms such as chest pain due to ischemia, dyspnea due to heart failure, and hypotension due to poor cardiac output. The ST-segment elevation seen on the ECG is indicative of significant myocardial injury. Prompt diagnosis and management are crucial in acute MI to prevent further complications and to minimize damage to the heart muscle. It is important to differentiate an acute MI from stable or unstable angina or other cardiovascular disorders, as the management and prognosis vary significantly.

Correct Answer: D

Rationale: A patient with chronic kidney disease prescribed a low-protein diet should avoid high-protein foods like grilled salmon, lentil soup, and beef stew. Chicken Caesar salad, on the other hand, typically contains a smaller amount of protein compared to the other options. This choice indicates an understanding of the need to limit protein intake while still enjoying a balanced meal. However, it is important to note that the quantity and portion sizes of high-protein ingredients in the salad should also be moderate to comply with a low-protein diet.

Correct Answer: B

Rationale: The presentation of a patient with diabetes mellitus showing symptoms of polyuria, polydipsia, nocturia, and fatigue along with laboratory findings of hyperglycemia, glycosuria, and ketonuria is indicative of diabetic ketoacidosis (DKA). DKA is a serious complication of diabetes characterized by hyperglycemia, metabolic acidosis, and ketosis. The increased glucose levels lead to glycosuria, causing osmotic diuresis resulting in polyuria, polydipsia, and nocturia. The body starts breaking down fats for energy in the absence of sufficient insulin, leading to the production of ketones causing ketonuria. The patient may also experience fatigue due to the metabolic abnormalities present in DKA.

Correct Answer: B

Rationale: When a patient with a suspected spinal injury is found unconscious, the priority action is to secure the airway without jeopardizing the cervical spine. A jaw thrust maneuver is the appropriate technique to open the airway in this situation because it allows for the maintenance of neutral alignment of the cervical spine while ensuring proper ventilation. Moving the patient to a flat surface or applying a cervical collar could potentially worsen the spinal injury if not done correctly, and checking for responsiveness should only be done after ensuring a patent airway. Therefore, the safest and most effective initial action is to perform a jaw thrust maneuver to establish a clear airway.
