Nursing Elites

1. Most water leaves the body by way of the:

• A. Lungs
• B. Intestines
• C. Skin
• D. Kidneys

Correct answer: D

Rationale: Most water leaves the body through the kidneys. The kidneys play a crucial role in filtering waste and excess substances from the blood to form urine, which is then excreted out of the body. Choices A, B, and C are incorrect because while a small amount of water can be lost through respiration, feces, and sweating, the primary organ responsible for regulating water balance and excretion is the kidneys.

2. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

3. Insulin forces which of the following electrolytes out of the plasma and into the cells?

• A. Calcium
• B. Magnesium
• C. Phosphorus
• D. Potassium

Correct answer: D

Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

4. What is the main purpose of quality improvement in healthcare?

• A. To increase healthcare costs
• B. To improve patient outcomes
• C. To decrease patient satisfaction
• D. To increase hospital stays

Correct answer: B

Rationale: The main purpose of quality improvement in healthcare is to improve patient outcomes by enhancing the quality and safety of healthcare services. Choice A is incorrect because the goal is not to increase healthcare costs but to optimize resources and provide cost-effective care. Choice C is incorrect as the aim is to increase patient satisfaction through better outcomes. Choice D is incorrect as the objective is to reduce hospital stays by improving care efficiency and effectiveness.

5. Which technique or method is used to determine whether or not the patient has an irregular pulse?

• A. Apical pulse
• B. Inspection
• C. Auscultation
• D. Percussion

Correct answer: A

Rationale: An apical pulse check is used to determine if the patient has an irregular pulse. The apical pulse is located at the point of maximal impulse (PMI) and is assessed using a stethoscope. Choice B, inspection, involves visual examination and is not used to assess pulse irregularities. Choice C, auscultation, involves listening to internal sounds using a stethoscope, which can be used to assess heart sounds but not specifically for pulse irregularities. Choice D, percussion, is a technique used to assess the density of body tissues or detect abnormal masses and is not used to determine pulse irregularities.
