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 C
Explanation
A. Partial non-rebreathing mask:
This mask delivers higher concentrations of oxygen than a nasal cannula. It has a reservoir bag that allows the client to rebreathe some exhaled air, increasing the oxygen concentration delivered. However, it may not be necessary for a client with mild shortness of breath and slightly reduced oxygen saturation.
B. Simple (Oxy Plus) mask:
The simple mask provides a higher concentration of oxygen than a nasal cannula but lacks the reservoir bag found in the non-rebreathing mask. It is generally used for moderate oxygen needs. However, it might be more than what is required for a client with mild shortness of breath and slightly reduced oxygen saturation.
C. Nasal cannula:
Nasal cannulas are commonly used for clients with mild respiratory distress. They deliver a lower to moderate concentration of oxygen and are well-tolerated by most clients. They are suitable for individuals with mild shortness of breath and can be adjusted based on the required flow rate.
D. Non-rebreathing mask:
The non-rebreathing mask provides the highest concentration of oxygen among the options listed. It includes a reservoir bag to deliver a higher oxygen concentration. It is typically reserved for clients with higher oxygen requirements. For a client with mild shortness of breath and slightly reduced oxygen saturation, this may be more than necessary.
Correct Answer is B
Explanation
A. Maintaining a diet high in dairy to increase protein necessary to prevent organ damage
Explanation: This statement is not accurate. While a balanced diet is important, there is no specific recommendation to maintain a diet high in dairy to prevent organ damage related to hypertension.
B. Use of strategies to prevent falls stemming from postural hypotension
Explanation: This is a correct and important consideration. Beta-blockers can cause postural hypotension (a drop in blood pressure upon standing), and strategies to prevent falls, such as rising slowly from a sitting or lying position, are crucial.
C. Limiting exercise to avoid injury that can be caused by increased intracranial pressure
Explanation: This statement is not accurate. Exercise is generally beneficial for individuals with hypertension, and beta-blockers do not cause increased intracranial pressure.
D. Increasing fluids to avoid extracellular volume depletion from the diuretic effects of the beta-blocker
Explanation: This statement is not accurate. Beta-blockers are not typically associated with diuretic effects. Diuretics are a different class of medications commonly used for hypertension.
