In assessing a client with ulcers on the lower extremity, which findings indicate that the ulcers are likely to be of venous, rather than arterial, origin?

Irregular ulcer shapes and severe edema.

Hairless lower extremities and cool feet.

Black ulcers and dependent rubor.

Absent pedal pulses and shiny skin.

Answer and Explanation

The Correct Answer is A

Choice A reason: Irregular ulcer shapes and severe edema are characteristic of venous ulcers, which are caused by impaired venous return and increased capillary pressure. Venous ulcers are usually located near the medial malleolus and have a shallow depth.

Choice B reason: Hairless lower extremities and cool feet are signs of arterial insufficiency, which reduces blood flow and oxygen delivery to the tissues. Arterial ulcers are usually located on the toes, heels, or lateral malleoli and have a deep, punched-out appearance.

Choice C reason: Black ulcers and dependent rubor are also signs of arterial insufficiency, indicating tissue necrosis and inflammation. Dependent rubor is a reddish-blue color of the lower extremity that occurs when the leg is lowered below the level of the heart.

Choice D reason: Absent pedal pulses and shiny skin are also signs of arterial insufficiency, indicating reduced blood flow and atrophy of the skin. The skin may also be dry, scaly, or cracked.

Correct Answer is C

Explanation

Choice A reason: An abdominal catheter is used for peritoneal dialysis, not hemodialysis. Hemodialysis requires access to a large blood vessel, usually in the arm or leg.

Choice B reason: Routine medications may need to be adjusted or avoided before or after hemodialysis, depending on their effects on blood pressure, fluid balance, and electrolytes.

Choice C reason: Insulin dosage may need to be reduced during hemodialysis because insulin is removed by the dialyzer and blood glucose levels may drop. This is the correct statement to include in client education.

Choice D reason: Potassium-rich foods should be limited in the diet of clients with chronic kidney disease and hemodialysis, because potassium can build up in the blood and cause cardiac arrhythmias.

Correct Answer is ["100"]

Explanation

To answer this question, we need to find the rate of infusion in milliliters per hour (mL/hr) that will deliver 1 liter (1000 mL) of 0.9% sodium chloride, USP intravenously (IV) over 10 hours. We can use the following formula to calculate the rate:

Rate(mL/hr)=Volume(mL)/Time(hr)

Plugging in the given values, we get:

Rate(mL/hr)=1000mL/10hr

Simplifying, we get:

Rate= 100mL/hr
