What is the first intervention when a patient has difficulty breathing post-surgery?

Correct Answer: A

Rationale: Administering oxygen is the initial intervention for a patient experiencing breathing difficulties post-surgery. Providing oxygen helps improve oxygenation and alleviate respiratory distress. Repositioning the patient, checking oxygen saturation, and elevating the head of the bed are important interventions but administering oxygen takes precedence in addressing hypoxia and respiratory compromise.

Correct Answer: B

Rationale: The correct answer is to limit fluid intake for a patient with chronic kidney disease. This restriction helps manage fluid balance to prevent fluid overload. Choices A, C, and D are incorrect. Limiting potassium intake is essential for some patients with kidney disease, but it is not the primary dietary restriction. Increasing protein intake is usually not recommended due to the impaired kidney function in these patients. Increasing carbohydrate intake is also not a standard recommendation for patients with chronic kidney disease.

Correct Answer: A

Rationale: Administering oxygen is the initial action for a healthcare provider when a patient presents with shortness of breath because it helps alleviate the patient's symptoms by improving oxygenation. Providing oxygen takes precedence over other actions such as repositioning the patient, checking for abnormal breath sounds, or assessing oxygen saturation. While these actions are important, ensuring the patient has an adequate oxygen supply is crucial in the initial management of shortness of breath.

Correct Answer: A

Rationale: The best intervention for a patient experiencing severe hypoglycemia is to administer IV dextrose. This intervention is necessary to rapidly raise blood sugar levels in critical situations. Administering oral glucose may not be effective in severe cases as the patient may be unable to consume it. Monitoring blood sugar levels and rechecking blood sugar in 15 minutes are important steps but not the initial best intervention for severe hypoglycemia.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT levels. Activated Partial Thromboplastin Time (aPTT) is crucial for assessing the therapeutic effectiveness of heparin, as it reflects the intrinsic pathway of the coagulation cascade. Monitoring aPTT helps ensure that the patient is within the therapeutic range of heparin, minimizing the risk of bleeding complications. Platelet count (choice B) is important to assess for potential heparin-induced thrombocytopenia but is not the primary lab value to monitor during heparin therapy. INR levels (choice C) are monitored in patients on warfarin therapy, not heparin. Sodium levels (choice D) are not directly related to heparin therapy monitoring.
