What is the initial action for a healthcare provider when a patient presents with shortness of breath?

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 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.

Correct Answer: A

Rationale: The correct answer is to monitor vital signs post-surgery. Vital signs provide crucial information about a patient's physiological status, helping detect early signs of complications such as shock, bleeding, or infection. Checking the surgical site for bleeding is important but falls secondary to monitoring vital signs, which give a broader overview of the patient's condition. Checking for abnormal breath sounds and skin color are also important assessments, but they are not as immediate and general as monitoring vital signs in detecting various post-surgical complications.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

Correct Answer: A

Rationale: Corrected Rationale: Monitoring daily weight is the most accurate method to assess fluid balance in patients receiving diuretics. Changes in weight reflect changes in fluid balance, making it a sensitive indicator. Monitoring intake and output (choice B) is important but may not provide a complete picture of overall fluid balance. Checking for edema (choice C) is a late sign of fluid imbalance and may not be sensitive enough to detect subtle changes. Monitoring blood pressure (choice D) is relevant but may not directly reflect fluid balance as it can be influenced by various other factors.
