Nursing Elites

1. How many calories does one pound of fat equal?

• A. 1500 calories
• B. 2500 calories
• C. 3500 calories
• D. 5000 calories

Correct answer: C

Rationale: One pound of body fat is equivalent to approximately 3500 calories. This is a generally accepted caloric value used in nutrition and weight management. It's important to note that this is an estimation and individual variations may occur. Choice A (1500 calories), Choice B (2500 calories), and Choice D (5000 calories) are incorrect because they do not match the generally accepted caloric value of 3500 calories for one pound of body fat.

2. A nurse is teaching a nutrition class for clients who have type 2 diabetes mellitus. Which of the following statements should the nurse include about management of acute illness?

• A. Consume carbs every 3-4 hrs
• B. Decrease fluid intake to 1000 mL per day
• C. Monitor blood glucose twice per day
• D. Check urine for ketones every 24 hrs

Correct answer: A

Rationale: The correct statement is to 'Consume carbs every 3-4 hours.' During acute illness, it is important to maintain a consistent carbohydrate intake to help manage blood glucose levels for clients with type 2 diabetes. This frequent consumption can prevent hypoglycemia and provide energy needed during illness. Decreasing fluid intake (choice B) is not recommended during acute illness, as hydration is crucial to prevent complications. Monitoring blood glucose (choice C) more frequently than twice a day is necessary during acute illness. Checking urine for ketones (choice D) should be done more frequently than once every 24 hours during illness to monitor for diabetic ketoacidosis.

3. 24 hours after the creation of a colostomy, what should Nurse Violy identify as the normal appearance of the stoma?

• A. Pink, moist, and slightly protruding from the abdomen
• B. Gray, moist, and slightly protruding from the abdomen
• C. Pink, dry, and slightly protruding from the abdomen
• D. Red, moist, and slightly protruding from the abdomen

Correct answer: A

Rationale: Following colostomy surgery, a healthy stoma should appear pink, moist, and slightly protruding from the abdomen, which is why option 'A' is the correct answer. A gray stoma (choice 'B') could indicate poor blood supply or necrosis, which is a serious complication. A dry stoma (choice 'C') is also not normal as it should be moist; a dry stoma may suggest dehydration or other complications. While a stoma can appear red (choice 'D'), this is not typically the normal color; it should usually be pink. Therefore, it's important for healthcare professionals to correctly identify the normal and abnormal appearances of a stoma to ensure proper patient care.

4. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

5. What is the purpose of a chest tube after a lobectomy procedure, as understood by the nurse?

• A. Prevent mediastinal shift
• B. Promote chest expansion of the remaining lung
• C. Drain fluids and blood accumulated post-operatively
• D. Remove the air in the lungs to promote lung expansion

Correct answer: C

Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.
