Nursing Elites

1. What physiologic role does magnesium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.

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. A client has bilateral eye patches in place following an injury. When the client's food tray arrives, which of the following interventions should the nurse take to promote independence in eating?

• A. Assign an assistive personnel to feed the client.
• B. Explain to the client that their tray is here and guide their hands to it.
• C. Describe to the client the location of the food on the tray.
• D. Ask the client if they would prefer a liquid diet.

Correct answer: C

Rationale: When a client has bilateral eye patches, promoting independence in eating is crucial to maintain dignity and autonomy. Describing the location of the food on the tray enables the client to locate and feed themselves. Assigning assistive personnel to feed the client (Choice A) takes away their independence. Merely informing the client that the tray is here and guiding their hands to it (Choice B) does not empower the client to eat independently. Asking if the client prefers a liquid diet (Choice D) is not directly addressing the client's ability to independently eat the current meal.

4. The nurse is caring for a client taking warfarin. Which meal brought in by the client's family is a priority to remove before the client eats it?

• A. Oriental cabbage salad with chicken
• B. Beef enchilada, rice, and beans
• C. Ham and cheese sandwich
• D. Macaroni salad and grapefruit slices

Correct answer: C

Rationale: The correct answer is C. Ham is high in vitamin K, which can interfere with warfarin. Vitamin K can decrease the effectiveness of warfarin, an anticoagulant medication. Choices A, B, and D do not contain high levels of vitamin K and are less likely to interfere with the client's warfarin therapy.

5. The provision of health information in the rural areas nationwide through television and radio programs and video conferencing is referred to as:

• A. Community health program
• B. Telehealth program
• C. Wellness program
• D. Red Cross program

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
