What are the manifestations of osteomyelitis?

Correct Answer: A

Rationale: Osteomyelitis often manifests as localized pain, swelling, and erythema due to infection in the bone. These symptoms are characteristic of inflammation and infection in the bone tissue. Elevated white blood cells (Choice B) may be present as part of the body's immune response to the infection but are not specific manifestations of osteomyelitis. Elevated calcium levels (Choice C) and low potassium levels (Choice D) are not typically associated with osteomyelitis.

Correct Answer: A

Rationale: In a patient with ventricular tachycardia and a pulse, synchronized cardioversion is the preferred electrical intervention. Synchronized cardioversion is used to treat unstable tachyarrhythmias like ventricular tachycardia with a pulse. Choice B, defibrillation, is used for pulseless ventricular tachycardia or ventricular fibrillation. Choice C, medication administration, may not provide immediate correction for unstable ventricular tachycardia. Choice D, pacing, is not the first-line treatment for ventricular tachycardia with a pulse.

Correct Answer: A

Rationale: The correct answer is A: Avoid foods high in potassium. During an acute episode of gastritis, it is advisable to avoid foods high in potassium as they can exacerbate symptoms. Potassium-rich foods may irritate the stomach lining, leading to increased discomfort. Choices B, C, and D are incorrect. Avoiding foods high in sodium is not specifically related to managing gastritis. Increasing exercise to reduce stress is a good general recommendation but not directly related to managing gastritis symptoms. Drinking milk as a snack is not recommended for gastritis as dairy products can sometimes worsen symptoms due to their fat content.

Correct Answer: A

Rationale: The correct answer is to avoid NSAIDs after cataract surgery to reduce the risk of bleeding. Choice B, wearing dark glasses when outdoors, is generally recommended after cataract surgery to protect the eyes from bright sunlight, but it is not the most critical instruction. Choice C, reporting green or yellow drainage immediately, is important to monitor for signs of infection, but it is not specific to cataract surgery. Choice D, itching is normal unless accompanied by pain and nausea, is not the most crucial advice post-cataract surgery. Therefore, the key instruction is to avoid NSAIDs to minimize bleeding risk.

Correct Answer: A

Rationale: Corrected Rationale: Muscle weakness is a common symptom of hypokalemia and should be closely monitored in affected patients. Hypokalemia is a condition characterized by low potassium levels in the blood, which can lead to muscle weakness, cramps, and even paralysis. While bradycardia (slow heart rate) can be associated with severe hypokalemia, monitoring for muscle weakness is more specific to the condition. Checking deep tendon reflexes is not typically a primary monitoring parameter for hypokalemia. Monitoring for hyperglycemia is not directly related to hypokalemia, as hypokalemia is primarily associated with potassium levels in the blood.
