1. What does a QRS Complex represent in an ECG reading?

Correct answer: C

Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.

2. A client who follows the dietary laws of Orthodox Judaism is being cared for by a nurse. Which of the following meal choices should the nurse request for the client?

Correct answer: B

Rationale: The correct meal choice for a client following the dietary laws of Orthodox Judaism is 'Spaghetti with tomato sauce.' Orthodox Judaism prohibits mixing meat and dairy and consuming pork. The other choices - 'Turkey and cheese sandwich' (mixing meat and dairy), 'Pork chop and applesauce' (contains pork), and 'Scrambled eggs and bacon' (mixing meat and dairy) - do not adhere to the kosher dietary laws.

3. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.

4. By force of law, therefore, the PRC-Board of Nursing released Resolution No. 14 Series of 1999 entitled: "Adoption of a Nursing Specialty Certification Program and Creation of Nursing Specialty Certification Council." This rule-making power is called:

Correct answer: B

Rationale: The correct answer is B: Regulatory Power. Regulatory power involves the authority to create rules and regulations that govern a specific area. In this case, the PRC-Board of Nursing's release of Resolution No. 14 Series of 1999 for the Nursing Specialty Certification Program falls under regulatory power as it establishes guidelines and standards for nursing specialty certification. Choices A, C, and D are incorrect. Quasi-judicial power involves making decisions on rights and obligations, quasi-legislative power involves creating regulations with the force of law, and executive/promulgating power involves enforcing and implementing laws and regulations.

5. What is the movement of water from an area of lower solute concentration to one of higher solute concentration called?

Correct answer: D

Rationale: The correct answer is D, Osmosis. Osmosis is the process where water moves from an area of low solute concentration to an area of high solute concentration. This movement equalizes the solute concentration in intracellular and extracellular fluids. Choices A, B, and C are incorrect because they do not describe the movement of water based on solute concentration levels.
