Which of the following does the nurse recognize is common in peripheral venous insufficiency?
Intermittent claudication
Brownish discoloration to the legs
Weak or absent pedal pulses
Unequal peripheral pulses between extremities
The Correct Answer is B
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 A
Explanation
A. Frequent change of position:
Frequent changes in position help prevent pooling of secretions and promote lung expansion. This simple and cost-effective measure is important in preventing complications related to immobility, such as pneumonia and atelectasis. It aids in maintaining optimal respiratory function.
B. Antibiotics: Antibiotics are used to treat bacterial infections and would not directly address the risks associated with decreased mobility.
C. Oxygen humidification: While oxygen therapy may be necessary in some cases, humidification is typically used to prevent drying of mucous membranes and is not a primary intervention for preventing complications of decreased mobility.
D. Chest physiotherapy: Chest physiotherapy involves techniques to mobilize respiratory secretions and may be indicated in specific situations. However, it is not as simple and cost-effective as frequent changes in position.
Correct Answer is ["0.75"]
Explanation
The nurse needs to calculate the correct dose of atropine for a client who has a prescription for 0.3 mg IV stat. The nurse knows that atropine is a medication that blocks the effects of the parasympathetic nervous system and is used to treat bradycardia, heart block, and some types of poisoning.
To find out how many milliliters of atropine the nurse will administer, the nurse can use the formula:
Dose ordered / Dose available = Volume to administer
Plugging in the values, the nurse gets:
0.3 mg / 0.4 mg per mL = 0.75 mL
Therefore, the nurse will administer 0.75 mL of atropine to the client IV stat.
