A nurse is reinforcing teaching with a client who wants to lose 0.9 kg (2 Ib) of body fat per week. The nurse knows that 0.45 kg (1 lb) of body fat is equal to 3,500 calories. The nurse should instruct the client to reduce his daily caloric intake by how many calories? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) calories

The correct answer is choice A. Washing hands after leaving the room is an important infection control measure for individuals who come into contact with clients on contact precautions. Choice B is incorrect because gowns are only necessary when there is a risk of contact with the client's body fluids. Choice C is incorrect because gloves should not be reused. Choice D is incorrect because the client should not leave the room while on contact precautions. Choice B is not correct because gowns are only necessary when there is a risk of contact with the client's body fluids. Choice C is not correct because gloves should not be reused. Choice D is not correct because the client should not leave the room while on contact precautions.

The correct answer is Choice a. "You will be moderately sedated during the procedure."

Choice A rationale: Colonoscopy is a common procedure used for both diagnostic and therapeutic purposes in gastroenterology. Moderate sedation, also known as conscious sedation, is typically administered to patients undergoing colonoscopy to ensure their comfort and cooperation during the procedure. This level of sedation allows the patient to maintain their protective reflexes and respond to verbal commands, while also reducing anxiety and discomfort. The sedative agents commonly used for colonoscopy include benzodiazepines such as midazolam and analgesics such as fentanyl. The nurse should emphasize the use of moderate sedation to the patient, reassuring them that they will be in a relaxed state throughout the procedure without compromising their safety.

Choice B rationale: The statement suggesting that the patient will lie on their right side for the procedure is incorrect. During a colonoscopy, patients are typically positioned on their left side with their knees drawn up towards their chest. This left lateral decubitus position facilitates the advancement of the colonoscope through the colon and provides better visualization for the healthcare provider performing the procedure. Placing the patient on the right side would not provide optimal positioning and may hinder the progress of the colonoscopy.

Choice C rationale: The information provided in statement c. is incorrect regarding the dietary restrictions before a colonoscopy. Prior to the procedure, patients are instructed to follow a clear liquid diet for 24 to 48 hours, depending on the healthcare provider's instructions. Clear liquids include water, clear broth, tea, coffee without milk or cream, strained fruit juices (such as apple or white grape juice), and sports drinks. Solid foods, as well as liquids that are not transparent, should be avoided during this preparatory period to ensure adequate bowel cleansing and visualization during the colonoscopy.

Choice D rationale: The recommendation to warm the liquid bowel preparation before consumption, as stated in option d., is incorrect. Bowel preparations typically consist of polyethylene glycol-based solutions, which are intended to be consumed at room temperature or chilled. Warming the solution could alter its composition and taste, potentially causing discomfort or nausea in the patient. It is essential for patients to follow the specific instructions provided by their healthcare provider or the product labeling regarding the administration of bowel preparation to ensure effective bowel cleansing before the colonoscopy.

Choice E rationale: Repeated for emphasis, the advice to warm the liquid bowel preparation before consumption is incorrect and redundant. Patients should adhere strictly to the instructions provided by their healthcare provider or the product labeling regarding the administration of bowel preparation. Warming the solution is not recommended and could compromise the effectiveness of the preparation, leading to suboptimal bowel cleansing and potentially impacting the accuracy of the colonoscopy results.
