Answer:

A double-blind study is one in which neither the participants nor the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results. Double-blind studies are particularly useful for preventing bias due to demand characteristics or the placebo effect.

For example, let's imagine that researchers are investigating the effects of a new drug. In a double-blind study, the researchers who interact with the participants would not know who was receiving the actual drug and who was receiving a placebo.

The nurse is caring for a client with a nursing diagnosis of impaired skin integrity related to a stage iii pressure ulcer. what
Nata [24]

The nurse is caring for a client with a nursing diagnosis of impaired skin integrity related to a stage iii pressure ulcer. The most important outcome for this client is to complete the head-to-toe assessment and include current treatment such as monitoring vital signs and laboratory results.

<h3 /><h3>What is a stage III pressure ulcer?</h3>

Corresponds to necrosis or damage to the subcutaneous tissue due to the loss of skin thickness, with stage III being the stage in which the wound may be larger than it appears on the skin surface, and may extend to the granulation tissue and epibole of the wound.

Therefore, in stage 3, the ulcer continues to develop, and may extend to the muscles, and this condition must be continuously monitored by nurses to reduce the infection in the wound that, if left untreated, can have serious consequences for the patient in the future.

Which type of roadway did North Carolina construct nearly five hundred miles of between the 1830s and 1860s?
g100num [7]

The correct answer is; Plank.

Further Explanation:

North Carolina started building plank roads in the late 1840's. These roads were easier to maintain and easier to drive on. Before the plank roads were built, the roads had long muddy roads and large holes and ruts that drivers had to navigate through.

The crews could only lay an estimated 40 miles of plank roads per year and this did cause issues. North Carolina had the largest plank road with a total of 500 miles built. The rods failed after a few years because it took so long to build.

Citizens were then using the railroad system since it was faster than traveling by horse and buggy. The people also did not like having to stop at the toll booth that had been set up on the road. The money collected at the toll booth was used to pay for maintenance of the plank road.
