A nurse is teaching about the energy needed at rest to maintain life-sustaining activities for a specific period of time. What is the nurse discussing?

Correct Answer: B

Rationale: The correct answer is B: Basal metabolic rate (BMR). BMR refers to the minimum amount of energy required to maintain basic physiological functions at rest. It accounts for about 60-75% of total energy expenditure. It is essential for sustaining life-sustaining activities such as breathing, circulating blood, and maintaining body temperature. Incorrect Choices: A: Resting energy expenditure (REE) is the total amount of energy expended by the body while at rest, including BMR and additional energy for daily activities. C: Nutrient density refers to the amount of nutrients per calorie in a food item, not the energy needed at rest. D: Nutrients are essential substances in food required for growth, maintenance, and repair, but they do not specifically refer to the energy needed at rest.

Correct Answer: A

Rationale: The correct answer is A because measuring capillary blood glucose level is a task that can be safely delegated to nursing assistive personnel. This task is within their scope of practice and does not require specialized nursing knowledge. Nursing assistive personnel can perform this task accurately with proper training and supervision. Incorrect choices: B: Measuring nasoenteric tube for insertion requires specialized training and assessment skills that nursing assistive personnel may not possess. C: Measuring pH in gastrointestinal aspirate involves interpretation and clinical judgment that should be done by a licensed nurse. D: Measuring the patient's risk for aspiration involves critical thinking and assessment skills that are beyond the scope of nursing assistive personnel.

Correct Answer: D

Rationale: The correct answer is D: Obese. This classification is based on the Body Mass Index (BMI) calculation, which takes into account weight and height. A BMI above 30 is considered obese, indicating excess body fat. Other choices are incorrect because they do not align with the BMI criteria for obesity. Choice A is incorrect as normal weight falls within a specific BMI range. Choice B is incorrect for individuals with a BMI below the normal range. Choice C is incorrect for individuals with a BMI between the overweight and obese categories.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): To determine the correct length of the nasogastric tube needed to be inserted, the nurse should measure from the tip of the earlobe to the nose and then to the xiphoid process. This method ensures that the tube reaches the stomach without coiling in the esophagus or being inserted too far down. The distance from the earlobe to the nose approximates the distance from the nose to the stomach, and measuring to the xiphoid process ensures proper placement. This technique minimizes the risk of complications such as aspiration or misplacement. Summary of Incorrect Choices: A: Measuring from the tip of the nose to the earlobe is incorrect because it does not take into account the distance to the stomach. B: Measuring from the tip of the earlobe to the xiphoid process alone is incorrect because it does not consider the distance through the nasal passage. D: Measuring from the tip of the nose to the earlobe to

Correct Answer: C

Rationale: The correct answer is C: Formula intolerance. When a patient develops diarrhea shortly after starting enteral feeding, formula intolerance is the most likely cause. This can occur due to the patient's inability to tolerate certain ingredients in the formula, leading to gastrointestinal upset. Antibiotics (choice A) and Clostridium difficile (choice B) typically take longer to cause diarrhea. Bacterial contamination (choice D) would usually result in more severe symptoms beyond just diarrhea. In this scenario, formula intolerance is the most logical explanation for the immediate onset of diarrhea after starting enteral feeding.
