Nursing Elites

1. You are to measure the client's initial blood pressure reading by doing all of the following EXCEPT:

• A. Take the blood pressure reading on both arms for comparison
• B. Listen to and identify the phases of Korotkoff sounds
• C. Pump the cuff to around 50 mmHg above the point where the pulse is obliterated
• D. Observe procedures for infection control

Correct answer: B

Rationale: When measuring blood pressure, it is crucial to follow specific steps to obtain accurate readings. Taking the blood pressure on both arms for comparison helps assess any variations. Pumping the cuff to around 50 mmHg above the point of pulse obliteration ensures accurate measurements. Observing procedures for infection control is vital to prevent the spread of infections. Listening to and identifying the phases of Korotkoff sounds are associated with auscultatory blood pressure measurements, not the initial blood pressure reading process.

2. 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.

3. What physiologic role does calcium 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: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

4. During the Emergent phase of a burn, the most fatal electrolyte imbalance in a burned client is:

• A. Hypokalemia
• B. Hyperkalemia
• C. Hypernatremia
• D. Hyponatremia

Correct answer: A

Rationale: During the Emergent phase of burns, the most fatal electrolyte imbalance is Hypokalemia. This is due to the shift of potassium from the intracellular space to the extracellular space, leading to low potassium levels in the blood. Choices B, C, and D are incorrect because Hyperkalemia, Hypernatremia, and Hyponatremia are not typically associated with the Emergent phase of burns and do not pose the same level of risk as Hypokalemia in this context.

5. A client is receiving education from a nurse regarding the dietary changes needed for weight loss. Which of the following actions should the nurse perform first?

• A. Educate the client about daily caloric requirements.
• B. Determine the client’s daily caloric intake.
• C. Provide the client with meal planning information.
• D. Show the client how to identify the fat content of packaged foods.

Correct answer: B

Rationale: The correct answer is to determine the client’s daily caloric intake first. This step is crucial in understanding the client's current dietary habits and establishing a baseline for creating an effective weight loss plan. Educating the client about daily caloric requirements (Choice A) can only be done effectively after knowing the client's current intake. Providing meal planning information (Choice C) and teaching the client how to identify fat content in foods (Choice D) come after determining the baseline caloric intake to tailor the plan accordingly.
