The healthcare provider prescribes regular insulin 10 units/hr IV. The IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline. How many mL/hr should the nurse program the infusion pump? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["10"]

To determine the mL/hr rate for the regular insulin infusion, we can set up a proportion: 10 units/hr (prescribed rate) = x mL/hr (unknown rate)

Since the IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline, we know that each mL of the solution contains 1 unit of regular insulin.

So, if 1 mL contains 1 unit, then x mL contains 10 units. x = 10 mL/hr

Correct Answer is B

Explanation

B. Severe edema is a common finding in venous insufficiency and is often present in the lower extremities. Venous hypertension leads to fluid leakage from capillaries, resulting in edema, which contributes to the development of venous ulcers. Venous ulcers typically have irregular shapes with irregular wound margins and may appear shallow or superficial.
A. Absent pedal pulses suggest arterial insufficiency, as reduced blood flow compromises peripheral circulation. Shiny skin, known as "thinning of the skin," is a characteristic finding in arterial insufficiency due to chronic ischemia and tissue hypoxia.
C. Hair loss on the lower extremities is a common finding in arterial insufficiency due to decreased blood flow to the hair follicles.
D. Black ulcers (gangrene) are indicative of tissue necrosis resulting from severe arterial insufficiency and lack of oxygen supply to the tissues. Dependent rubor refers to redness of the lower extremities when the legs are in a dependent position.

Correct Answer is ["1.6"]

Explanation

To determine how many milliliters (mL) of diazepam the nurse should administer to the client, first, we need to calculate the amount of medication needed for each dose.

The prescribed dose is 8 mg of diazepam.

Volume= Desired dose/available concentration per ml

Available concentration per ml= 10mg/2ml Available concentration per ml= 5mg/ml Volume= 8mg/5mg per ml

Volume= 1.6ml

So, the nurse should administer 1.6 mL of diazepam to the client.
