A nurse is preparing to clean a blood spill on a bedside table.
Which of the following solutions should the nurse plan to use?

Choice A rationale

Placing the cap of a sterile solution on a clean surface with the inside facing down can contaminate the cap. It should be placed with the inside facing up to maintain sterility.

Choice B rationale

Placing a sterile instrument within 1.3 cm (0.5 in) of the edge of the sterile field risks contamination, as the edges are considered non-sterile. Instruments should be placed well within the sterile field.

Choice C rationale

Opening the top flap of the sterile tray package away from their body ensures that the sterile contents are not contaminated by the nurse's clothing or body, maintaining the sterility of the field.

Choice D rationale

Dropping sterile objects onto the field from a height of 5 cm (2 in) can cause contamination due to the potential for the objects to fall outside the sterile field. Objects should be placed gently onto the field without dropping them.

Choice A rationale

Ulcerative colitis often results in inflammation and ulcers in the colon lining, which can lead to bleeding and a positive fecal occult blood test. This is a common complication of the condition.

Choice B rationale

Cholecystitis, an inflammation of the gallbladder, does not typically cause gastrointestinal bleeding or a positive fecal occult blood test. It is more associated with abdominal pain and digestive issues.

Choice C rationale

The use of laxatives generally does not cause internal bleeding that would result in a positive fecal occult blood test. Laxatives are more likely to cause changes in bowel habits and diarrhea.

Choice D rationale

Stomatitis, inflammation of the mouth, is unlikely to cause a positive fecal occult blood test. It primarily affects the oral cavity and is not associated with gastrointestinal bleeding. .
