The physician orders warfarin (Coumadin) 10 mg PO to be administered to a client at 1800 today. The pharmacy only has 2.5 mg tablets available. How many tablets will the nurse administer?
The Correct Answer is ["4"]
Warfarin (Coumadin) is an anticoagulant medication that prevents blood clots from forming or growing larger. It is prescribed for clients who have atrial fibrillation, deep vein thrombosis, pulmonary embolism, or artificial heart valves.
The physician orders warfarin 10 mg PO to be administered to a client at 1800 today. The pharmacy only has 2.5 mg tablets available. To calculate the number of tablets that the nurse will administer, the nurse will divide the ordered dose by the available dose. The formula is:
Number of tablets = Ordered dose / Available dose
Number of tablets = 10 mg / 2.5 mg
Number of tablets = 4
Therefore, the nurse will administer 4 tablets of warfarin 2.5 mg PO to the client at 1800 today

Correct Answer is D
Explanation
A. Intake and output:
Intake and output refer to monitoring the amount of fluids a person consumes (intake) and eliminates (output) through urine, feces, and other means. While tracking fluid intake and output is important, it may not provide a direct indication of excess fluid retention.
B. Pitting pedal edema:
Pitting pedal edema is swelling in the lower extremities, particularly the ankles and feet, that leaves an indentation (pit) when pressure is applied. This can be a sign of fluid retention but may not always be the earliest or most reliable indicator.
C. Crackles in the bases of the lungs:
Crackles or rales in the bases of the lungs can be indicative of pulmonary congestion, which may occur due to fluid accumulation. However, crackles alone may not always be specific to fluid overload and can be present in other respiratory conditions.
D. Daily weights:
Daily weights are a critical and sensitive measure for assessing fluid balance. Sudden weight gain, especially over a short period, can be a strong indicator of fluid retention. Monitoring weight on a daily basis helps to detect changes early, allowing for prompt intervention.
Correct Answer is ["50"]
Explanation
To calculate the drops per minute for the ondansetron infusion, we need to use the formula:
drops per minute = (volume in mL x drop factor) / time in minutes
In this case, the volume is 50 mL, the drop factor is 15 gtt/mL, and the time is 15 minutes. Plugging these values into the formula, we get:
drops per minute = (50 x 15) / 15
drops per minute = 750 / 15
drops per minute = 50
Therefore, the nurse should set the infusion pump to deliver 50 drops per minute of ondansetron to the client with severe nausea.
