Nursing Elites

1. What is a major feature of the therapeutic lifestyle changes (TLC) recommended for the treatment of high blood cholesterol?

• A. Avoiding all foods that contain cholesterol
• B. Reducing sodium intake to less than 2 g/day
• C. Limiting total fat intake to less than 30% of energy intake
• D. Limiting saturated fat intake to less than 7% of energy intake

Correct answer: D

Rationale: The correct answer is D, 'Limiting saturated fat intake to less than 7% of energy intake.' This is a central feature of the therapeutic lifestyle changes (TLC) recommended for treating high blood cholesterol. Saturated fats can increase low-density lipoprotein (LDL) cholesterol, a significant risk factor for heart disease. Choice A is incorrect because while it is recommended to limit cholesterol intake, it's not suggested to avoid all foods containing cholesterol entirely in the TLC. Choice B is also incorrect as although reducing sodium intake is beneficial for controlling blood pressure, it's not specifically targeted in the TLC for managing high cholesterol. Lastly, while limiting total fat intake is a healthy guideline, it's not as specific or effective as limiting saturated fat intake, making choice C also incorrect.

2. You are taking care of critically ill client and the doctor in charge calls to order a DNR (do not resuscitate) for the client. Which of the following is the appropriate action when getting DNR order over the phone?

• A. Have the registered nurse, family spokesperson, nurse supervisor and doctor sign
• B. Have 2 nurse validate the phone order, both nurses sign the order and the doctor should sign his order within 24
• C. Have the registered nurse, family and doctor sign the order
• D. Have 1 nurse take the order and sign it and have the doctor sign it within 24 hours

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.

3. A client who is 2 days postoperative following abdominal surgery is about to progress from a clear liquid diet to full liquids. Which of the following items should the nurse tell the client he may now request to have on his meal tray?

• A. Cranberry juice
• B. Flavored gelatin
• C. Skim milk
• D. Chicken broth

Correct answer: A

Rationale: Cranberry juice is an appropriate choice for a client transitioning from a clear liquid diet to full liquids post abdominal surgery. It provides hydration and some essential nutrients. Flavored gelatin is usually allowed on a clear liquid diet and may not be suitable for a full liquids phase. Skim milk and chicken broth are typically introduced in a later stage of the diet progression, closer to a soft diet, due to their higher protein and fat content.

4. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

• A. hemoglobin
• B. transferrin
• C. myoglobin
• D. hepcidin

Correct answer: A

Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.

5. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.
