A patient is in the intensive care unit and receiving an infusion of milrinone (Primacor) for severe

Correct Answer: D

Rationale: Milrinone and furosemide are two medications that are known to interact when mixed together in the same intravenous line. Milrinone is a phosphodiesterase inhibitor that works to increase cardiac contractility and output, while furosemide is a loop diuretic used to promote diuresis. When mixed together, the pH level of the solution can become altered, leading to potential precipitation or inactivation of one or both drugs.

Correct Answer: C

Rationale: Amiodarone is the drug of choice for treating severe ventricular dysrhythmias, such as those experienced by the patient in the intensive care unit with acute myocardial infarction. It is a class III antiarrhythmic medication that works by prolonging the action potential duration and refractory period, thereby helping to stabilize the electrical activity of the heart. Amiodarone is effective in treating various types of ventricular dysrhythmias, including ventricular tachycardia and ventricular fibrillation, making it a suitable choice in this scenario. Diltiazem and verapamil are calcium channel blockers primarily used for supraventricular arrhythmias and are not the first-line treatment for severe ventricular dysrhythmias. Adenosine is used for terminating supraventricular tachycardias, not ventricular dysrhythmias. Amiodarone

Correct Answer: A

Rationale: When a patient is on Warfarin therapy, the two primary tests that need to be monitored are the Prothrombin Time (PT) and the International Normalized Ratio (INR). Warfarin works by inhibiting the activity of Vitamin K-dependent clotting factors, and both PT and INR are measures of the extrinsic pathway of coagulation, which is primarily affected by Warfarin. PT measures the time it takes for blood to clot, while INR is a standardized calculation based on the PT value to monitor the effectiveness and safety of Warfarin therapy. Monitoring these tests helps ensure that the patient's blood is not too thick (increased risk of clotting) or too thin (increased risk of bleeding) while on Warfarin.

Correct Answer: C

Rationale: A solution is a liquid preparation that contains one or more chemical substances dissolved in a suitable solvent. The solute (chemical substance) is evenly dispersed and mixed with the solvent, resulting in a homogenous mixture. Solutions are commonly used in medicine for oral administration, injections, topical treatments, and various other applications due to their ability to provide accurate dosing and rapid absorption into the body. decoction is a liquid derived from boiling plant material, fluid extract is a concentrated liquid extract of a substance, spirits are alcoholic solutions, and syrup is a viscous solution containing sugar.
