Correct Answer: C

Rationale: The correct answer is C: high protein, low residue. For patients with ulcerative colitis, a high protein diet helps in tissue healing and repair. Low residue foods are recommended to reduce bowel irritation. Choice A is incorrect because low protein can impair healing. Choice B is unsuitable as high fiber may worsen symptoms. Choice D is not ideal as high carbohydrate can be difficult to digest for colitis patients.

Correct Answer: A

Rationale: The correct answer is A because the Nursing Interventions Classification (NIC) system is not designed to help medical students determine the cost of care. The NIC system focuses on standardizing and categorizing nursing interventions to improve communication, documentation, and patient care. Choice B is incorrect because it correctly identifies one of the benefits of using the NIC system - enhancing communication among nurses. Choice C is incorrect because it suggests a valid use of the NIC system for organizing orientation and explaining nursing interventions. Choice D is incorrect because it accurately states that the NIC system can improve documentation in the electronic health record, which is one of its purposes.

Correct Answer: B

Rationale: The correct answer is B: Dyspnea on exertion. In older clients, dyspnea on exertion is often the earliest symptom of heart failure due to decreased cardiac reserve. This occurs when the heart cannot pump enough blood to meet the body's demands during physical activity. Increased urine output (A) is not typically an early symptom of heart failure. Swollen joints (C) are more indicative of arthritis or inflammation, not necessarily heart failure. Nausea and vomiting (D) are not typical early symptoms of heart failure and are more commonly associated with gastrointestinal issues.

Correct Answer: C

Rationale: The correct answer is C: Urinary output every hour. This is because assessing urinary output is crucial for monitoring fluid balance in burn patients. Adequate urine output indicates proper fluid replacement, while decreased output may indicate dehydration. Recording weights daily (choice A) may be important but not as immediate and specific as urinary output. Blood pressure every 15 minutes (choice B) is too frequent and not directly related to fluid replacement in this context. Monitoring peripheral edema every 4 hours (choice D) is not as reliable as urinary output for assessing fluid status.

Correct Answer: C

Rationale: The correct answer is C: Vitamin D. In hypoparathyroidism, there is a deficiency of parathyroid hormone leading to low calcium levels. Vitamin D helps in the absorption of calcium from the intestines, thus aiding in maintaining normal calcium levels. It is often prescribed along with calcium supplements to support bone health and prevent complications. Folic acid (A) is not directly related to the treatment of hypoparathyroidism. Potassium (B) is not typically prescribed for this condition and can be harmful in high levels. Iron (D) is not directly involved in calcium metabolism and is not part of the standard treatment regimen for hypoparathyroidism.
