Which electrolyte imbalance is commonly associated with furosemide?

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, commonly causes the loss of potassium in the urine, leading to hypokalemia. This electrolyte imbalance can result in various complications such as cardiac arrhythmias and muscle weakness. Choice B, Hyponatremia, is not typically associated with furosemide use. Choice C, Hyperkalemia, is the opposite of the expected electrolyte imbalance caused by furosemide. Choice D, Hypercalcemia, is not a common side effect of furosemide.

Correct Answer: A

Rationale: The correct answer is to monitor INR for a patient on warfarin therapy. INR monitoring is crucial as it helps assess the therapeutic effectiveness and safety of warfarin. INR stands for International Normalized Ratio, and it measures the blood's ability to clot. Monitoring potassium levels (Choice B) is not specific to warfarin therapy. Monitoring platelet count (Choice C) is important but not the primary lab value for assessing warfarin therapy. Monitoring sodium levels (Choice D) is not directly related to warfarin therapy.

Correct Answer: A

Rationale: The correct initial nursing action for a patient presenting with chest pain is to administer aspirin. Aspirin helps reduce the risk of further clot formation in patients experiencing chest pain, as it has antiplatelet effects. Repositioning the patient, providing pain relief, or preparing for surgery are not the first-line interventions for chest pain. Repositioning the patient may be necessary to ensure comfort and safety, pain relief can be provided after further assessment and diagnostic tests, and preparing for surgery would only be considered after a thorough evaluation and confirmation of the need for surgical intervention.

Correct Answer: A

Rationale: Administering oxygen is the best intervention for a patient with respiratory distress because it helps improve oxygenation levels and alleviates respiratory distress directly. Providing oxygen addresses the primary issue of inadequate oxygen supply, which is crucial in managing respiratory distress. Repositioning the patient, while important for airway clearance, may not address the immediate need for oxygen. Providing bronchodilators and humidified air can be beneficial in certain respiratory conditions, but when a patient is in respiratory distress, ensuring adequate oxygenation through oxygen administration takes precedence.

Correct Answer: A

Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.
