Nursing Elites

1. What is the first step in the scientific method?

• A. Conduct an experiment
• B. Make an observation and ask a question
• C. Formulate a hypothesis
• D. Reach a consensus

Correct answer: B

Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.

2. A patient following a vegetarian diet might be at risk for deficiency in which nutrient?

• A. Vitamin C
• B. Vitamin B12
• C. Vitamin A
• D. Vitamin D

Correct answer: B

Rationale: Vitamin B12 is primarily found in animal products, so vegetarians may need supplementation.

3. Which of the following is a normal finding during assessment of a Chest tube in a 3 way bottle system?

• A. There is a continuous bubbling in the drainage bottle
• B. There is an intermittent bubbling in the suction control bottle
• C. The water fluctuates during inhalation of the patient
• D. There is 3 cm of water left in the water seal bottle

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. A nurse is teaching about nutrition to a client who has a new diagnosis of chronic kidney disease. Which of the following recommendations should the nurse include in the teaching?

• A. Increase phosphorus intake
• B. Limit calcium intake
• C. Limit protein intake
• D. Increase potassium intake

Correct answer: C

Rationale: The correct recommendation for a client with chronic kidney disease is to limit protein intake. Excessive protein consumption can strain the kidneys as they work to eliminate waste products from protein metabolism. This can worsen kidney function in individuals with chronic kidney disease. Therefore, limiting protein intake is crucial in managing this condition. Choices A, B, and D are incorrect. Increasing phosphorus intake can be harmful in kidney disease as it can lead to mineral imbalances. Limiting calcium intake is not typically necessary unless the client has specific complications. Increasing potassium intake may also be inappropriate as potassium levels can be affected in kidney disease.

5. Why is atherosclerosis dangerous to arterial function?

• A. It diminishes central circulation
• B. It causes decreased blood pressure on artery walls
• C. It narrows the arterial lumen so a clot can easily block it
• D. It increases arterial elasticity

Correct answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
