Nursing Elites

1. What is the function of the gallbladder?

• A. to store bile
• B. to produce bile
• C. to digest bile
• D. to modify bile to a liquid form

Correct answer: A

Rationale: The correct answer is A: "to store bile." The gallbladder acts as a reservoir for bile produced by the liver. It releases bile into the small intestine to aid in the digestion of fats. Choice B is incorrect because the liver produces bile, not the gallbladder. Choice C is incorrect as the gallbladder does not digest bile but stores and releases it for digestion. Choice D is incorrect because bile is already in liquid form; the gallbladder does not modify it to a liquid state.

2. A nurse is reviewing the laboratory results for a client who has a history of atherosclerosis and notes elevated cholesterol levels. Which of the following statements by the client indicates the nurse should plan follow-up teaching on a low-cholesterol diet?

• A. "I flavor my meat with lemon juice."?
• B. "I eat two eggs for breakfast each morning."?
• C. "I cook my food with canola oil."?
• D. "I take an omega-3 supplement daily."?

Correct answer: B

Rationale: The correct answer is B. Eggs are high in cholesterol, so someone with elevated cholesterol levels, especially with a history of atherosclerosis, should be cautious about egg consumption. Choices A, C, and D are not as concerning for cholesterol levels. Lemon juice, canola oil, and omega-3 supplements do not significantly impact cholesterol levels compared to consuming eggs regularly.

3. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

4. The nurse is correct in performing suctioning when she applies the suction intermittently during:

• A. Insertion of the suction catheter
• B. Withdrawing of the suction catheter
• C. both insertion and withdrawing of the suction catheter
• D. When the suction catheter tip reaches the bifurcation of the trachea

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. Uric acid kidney stones are most commonly associated with what condition?

• A. diabetes
• B. hypercalcemia
• C. gout
• D. diarrhea

Correct answer: C

Rationale: Gout is a condition characterized by high levels of uric acid, which can lead to the formation of uric acid kidney stones due to the crystallization of uric acid in the kidneys.
