A client is ordered to receive 4 g of a medication. The pharmacy has the medication available in a concentration of 160 mg per 5 mL. How many mL should the client receive?
The Correct Answer is ["125"]
To calculate the amount of mL that the client should receive, we need to use the formula:
mL = (g * 5 mL) / mg
where g is the ordered dose of the medication, mg is the concentration of the medication, and mL is the volume of the solution.
Plugging in the given values, we get:
mL = (4 g * 5 mL) / 160 mg
Simplifying, we get:
mL = 0.125 g/mL
Multiplying by 1000 to convert grams to milligrams, we get:
mL = 125 mg/mL
Therefore, the client should receive 125 mL of the solution.

Correct Answer is B
Explanation
A. Intermittent claudication:
Intermittent claudication is more commonly associated with peripheral arterial insufficiency rather than venous insufficiency. It is caused by inadequate blood flow to the muscles during activity, resulting in cramping or pain that typically resolves with rest.
B. Brownish discoloration to the legs:
Brownish discoloration to the legs, often referred to as hemosiderin staining, is a common finding in peripheral venous insufficiency. It occurs due to the breakdown of red blood cells and the deposition of hemosiderin in the tissues, especially around the ankles.
C. Weak or absent pedal pulses:
Weak or absent pedal pulses are more indicative of peripheral arterial insufficiency rather than venous insufficiency. Peripheral arterial disease can result in decreased blood flow to the extremities, leading to diminished pulses.
D. Unequal peripheral pulses between extremities:
Unequal peripheral pulses between extremities are also more suggestive of arterial insufficiency. Conditions such as atherosclerosis or arterial embolism can cause variations in pulses between different limbs.
Correct Answer is B
Explanation
A. “I will have canned chicken noodle soup with crackers and an apple for lunch.”
This option may not be the best choice for a low-sodium diet. Canned soups often contain high levels of sodium.
B. “I will have a tossed salad with cheese and croutons for lunch.”
This option is a better choice, as salads with fresh vegetables can be lower in sodium compared to other options.
C. “I will have a ham and cheese sandwich for lunch.”
Ham and cheese are generally high in sodium, so this would not be a suitable choice for a low-sodium diet.
D. “I will have a baked potato with broiled chicken for dinner.”
This option seems to be a good choice. Baked potato and broiled chicken can be part of a low-sodium meal.
