The nurse is caring for a client who suffers from frequent blood clots and currently taking argatroban (Hospira). Which of the following conditions in the client's medical history would require them to take argatroban (Hospira)?
Heparin induced thrombocytopenia.
Myocardial infarction
Gastrointestinal Bleeding
Hepatotoxicity
The Correct Answer is A
A. Argatroban is specifically indicated for patients with heparin-induced thrombocytopenia (HIT), as it is a direct thrombin inhibitor that does not cause further platelet depletion.
B. Myocardial infarction is treated with different classes of anticoagulants or antiplatelet medications, not specifically argatroban.
C. Gastrointestinal bleeding would generally be a contraindication to anticoagulation therapy rather than an indication for argatroban use.
D. Hepatotoxicity could be a concern when using argatroban, especially as it is metabolized in the liver, but it does not indicate a need for this medication.

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.
Correct Answer is D
Explanation
A. While aspirin has anti-inflammatory properties, this is not the primary reason it is prescribed after an MI.
B. Aspirin does not primarily function as an anti-pyretic in this context; its use is focused on cardiovascular benefits.
C. Aspirin does not have antiemetic properties and is not indicated for nausea control.
