1. Which of the following provides the least amount of potassium?

Correct answer: D

Rationale: Cheese provides less potassium compared to broccoli, potatoes, and bananas, which are all rich in this essential mineral.

2. Which mineral is a principal component of cell membranes?

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

3. This flip-over card is usually kept in a portable file at the Nurse’s Station. It has 2-parts: the activity and treatment section and a nursing care plan section. This carries information about basic demographic data, primary medical diagnosis, current orders of the physician to be carried out by the nurse, written nursing care plan, nursing orders, scheduled tests and procedures, safety precautions in patient care and factors related to daily living activities. This record is used in the charge-of-shift reports or during the bedside rounds or walking rounds. What record is this?

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. Which two dietary components may help decrease blood cholesterol levels?

Correct answer: A

Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.

Correct answer: B
