What is the most important assessment for a patient with respiratory distress?

Correct Answer: A

Rationale: Monitoring oxygen saturation is crucial in assessing a patient with respiratory distress because it helps determine if the patient is receiving adequate oxygen. Oxygen saturation levels provide immediate feedback on the efficiency of oxygen delivery to the tissues. Checking for abnormal breath sounds (Choice B) is relevant in respiratory assessments, but it is secondary to assessing oxygen saturation. Pitting edema (Choice C) and performing a neurological exam (Choice D) are not directly related to assessing respiratory distress and are not the primary focus when managing a patient with breathing difficulties.

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 aPTT in patients receiving heparin therapy. Activated Partial Thromboplastin Time (aPTT) is crucial to assess the therapeutic effectiveness of heparin and to prevent bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy, not heparin. Platelet count (Choice C) monitoring is essential for detecting heparin-induced thrombocytopenia rather than assessing heparin therapy itself. Monitoring sodium levels (Choice D) is not directly related to heparin therapy monitoring.

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.
