What are the causes of a pressure ulcer? (Select all that apply.)

Choice A reason: Obtaining a PAPR mask is not a step in preparing a sterile field. A PAPR mask is a powered airpurifying respirator that protects the wearer from airborne contaminants. It is not required for setting up a sterile field, unless the client has a highly infectious disease.

Choice B reason: Do not turn away from the sterile field is a step in preparing a sterile field. Turning away from the sterile field can contaminate the field or the items on it. The nurse should always face the sterile field and keep it in view.

Choice C reason: Add items to the sterile field by dropping them gently is a step in preparing a sterile field. Dropping items gently onto the sterile field prevents splashing or touching the field or the items. The nurse should open the sterile packages away from the field and drop the items close to the edge of the field.

Choice D reason: Covering the sterile field once it is set up is not a step in preparing a sterile field. Covering the sterile field can compromise its sterility and create moisture that can harbor microorganisms. The nurse should not cover the sterile field unless it is necessary to move it or store it for later use.

Choice E reason: Preparing the client before setting up the sterile field is a step in preparing a sterile field. Preparing the client involves explaining the procedure, obtaining consent, providing privacy, and positioning the client. The nurse should prepare the client before setting up the sterile field to avoid leaving the field unattended or exposing it to the client's body fluids.

Choice A reason: Alcohol can trigger a gout attack because it increases the production and decreases the excretion of uric acid, which is the substance that causes inflammation and pain in the joints. Alcohol also dehydrates the body, which can worsen the symptoms of gout.

Choice B reason: Fruit juice is not a beverage that can trigger a gout attack. Fruit juice contains natural sugars and antioxidants, which may have a beneficial effect on the uric acid levels and the inflammation in the body. However, fruit juice should be consumed in moderation, as excess sugar intake can lead to weight gain and other health problems.

Choice C reason: Milk is not a beverage that can trigger a gout attack. Milk contains protein and calcium, which may help lower the uric acid levels and the risk of gout. Milk also has antiinflammatory properties, which may reduce the pain and swelling in the joints.

Choice D reason: Coffee is not a beverage that can trigger a gout attack. Coffee contains caffeine and antioxidants, which may have a protective effect on the uric acid levels and the inflammation in the body. Coffee also has a diuretic effect, which may help flush out the excess uric acid from the kidneys.
