Exhibits

Complete the following sentence by using the following options.

Based on the patient's current medications, the nurse knows to monitor
dropdown
for heparin and
dropdown
for warfarin sodium.

Answer and Explanation

The Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"D"}

aPTT (Activated Partial Thromboplastin Time) is the primary lab test used to monitor the effectiveness of unfractionated heparin therapy. Heparin works by activating antithrombin III, which inhibits thrombin and factor Xa, thus prolonging the aPTT. Monitoring aPTT helps ensure that the heparin dose is therapeutic and reduces the risk of bleeding.

PT-INR (Prothrombin Time - International Normalized Ratio) is used to monitor patients on warfarin therapy. Warfarin inhibits vitamin K-dependent clotting factors, which affects the prothrombin time (PT). The INR standardizes PT results, allowing for consistent monitoring of anticoagulation status. It is critical to maintain the INR within the therapeutic range to balance the risk of thrombosis against the risk of bleeding.

Correct Answer is C

Explanation

A. Calcium channel blockers primarily decrease heart rate and contractility, not increase them.

B. While they can indirectly improve oxygen supply by reducing myocardial oxygen demand, they do not directly increase systemic oxygen.

C. This option accurately describes the mechanism of action of calcium channel blockers, which decrease heart contractility and conduction through the AV node, helping to manage dysrhythmias.

D. Calcium channel blockers do not act on beta cells; they specifically inhibit calcium influx into cardiac and vascular smooth muscle cells.
