A client has a patch test performed with the following results. Which of the following is the best response the nurse will offer the client regarding the observations from the test?

Choice A Reason: Depth perception is the ability to judge the distance and position of objects in three-dimensional space. Depth perception is assessed by asking the client to touch the tip of a pen or pencil held by the nurse, or by using a stereopsis test.

Choice B Reason: Peripheral vision is the ability to see objects and movements outside the direct line of vision. Peripheral vision is assessed by asking the client to shake the hand of the nurse, who stands at an angle to the client's side, or by using a confrontation test.

Choice C Reason: Color deficit is the inability to distinguish certain colors or shades of colors. Color deficit is assessed by asking the client to identify numbers or shapes on a color plate test, such as the Ishihara test.

Choice D Reason: Double vision is the perception of two images of a single object. Double vision is assessed by asking the client to cover one eye and look at an object, then switch eyes and compare the images, or by using a cover-uncover test.

Choice A reason: This is incorrect because administering IV ketorolac is not a priority intervention for a client with cholecystitis. Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can cause gastrointestinal bleeding and kidney damage, which are contraindicated in cholecystitis. The nurse should administer analgesics as prescribed, but only after assessing the pain level and severity.

Choice B reason: This is incorrect because reporting findings to healthcare provider is not a priority intervention for a client with cholecystitis. The nurse should communicate with the healthcare provider about the client's condition and treatment plan, but only after assessing the pain level and other vital signs.

Choice C reason: This is incorrect because offering a high-calorie, high-fat meal is not an intervention for a client with cholecystitis, but a potential trigger. High-fat foods can stimulate the gallbladder to contract and cause more pain and inflammation. The nurse should advise the client to avoid fatty foods and follow a low-fat diet.

Choice D reason: This is the correct answer because assessing the pain level is a priority intervention for a client with cholecystitis. Pain is the most common symptom of cholecystitis and can indicate the severity and complications of the condition. The nurse should assess the pain level using a numeric or descriptive scale, and monitor for changes in location, intensity, and duration.
