Nursing Elites

1. Where are most body fluids located?

• A. Intravascular space.
• B. Intracellular space.
• C. Extracellular space.
• D. Transcellular space.

Correct answer: B

Rationale: Most body fluids are located within cells in the intracellular space. While the extracellular space also contains body fluids, the majority is found within the cells. Intravascular space refers to fluids within blood vessels, and transcellular space includes fluids in compartments like cerebrospinal, pleural, and peritoneal cavities.

2. A patient is starting on a statin medication for hyperlipidemia. What critical instruction should the nurse provide?

• A. Take the medication at night to reduce the risk of muscle pain and other side effects.
• B. Take the medication in the morning with breakfast to improve absorption.
• C. Avoid alcohol consumption while taking this medication to reduce the risk of liver damage.
• D. Take the medication with a high-fat meal to increase its effectiveness.

Correct answer: A

Rationale: The correct answer is A. Statins like atorvastatin should be taken at night to reduce the risk of muscle pain and other side effects. Taking the medication with a high-fat meal (choice D) is not recommended as it can decrease the effectiveness of the medication. Alcohol consumption (choice C) should be moderated but does not need to be completely avoided unless contraindicated. Taking the medication with breakfast (choice B) may not be as effective as taking it at night due to the circadian rhythm of cholesterol synthesis.

3. What function does aldosterone serve in the body?

• A. Aldosterone causes a release of sodium from the body, decreases fluid volume, and decreases blood pressure
• B. Aldosterone causes a retention of sodium in the body, increases fluid volume, and increases blood pressure
• C. Aldosterone causes a release of sodium from the body, increases fluid volume, and decreases blood pressure
• D. Aldosterone enhances intracellular sodium production and lowers blood pressure

Correct answer: B

Rationale: Aldosterone functions by causing the retention of sodium in the body, which results in an increase in fluid volume and blood pressure. Choice A is incorrect because aldosterone actually promotes sodium retention rather than release. Choice C is incorrect as it states that aldosterone decreases fluid volume, which is not accurate. Choice D is incorrect because aldosterone does not enhance intracellular sodium production; instead, it primarily acts on sodium reabsorption in the kidneys.

4. The canola plant's genome is altered to produce an herbicide-resistant crop. The canola oil produced from this crop is an example of a:

• A. pesticide-free food.
• B. saturated fat food.
• C. genetically modified food.
• D. product that is pure.

Correct answer: C

Rationale: The correct answer is C: genetically modified food. Canola plants with altered genomes to be herbicide-resistant are an example of genetically modified organisms (GMOs). Genetically modified foods have their genetic material modified for various purposes, such as enhancing resistance to pests, herbicides, or improving nutritional content. Choice A, 'pesticide-free food,' is incorrect because genetic modification does not necessarily make the food pesticide-free. Choice B, 'saturated fat food,' is incorrect as it does not relate to the genetic modification of the canola plant. Choice D, 'product that is pure,' is too vague and does not specifically address the genetic modification aspect of the canola plant.

5. When educating a patient starting on oral contraceptives, what should the nurse include regarding the medication's effectiveness?

• A. Oral contraceptives are 100% effective when taken correctly.
• B. Oral contraceptives are effective immediately after starting.
• C. Oral contraceptives are less effective if taken with certain antibiotics.
• D. Oral contraceptives are less effective if taken with food.

Correct answer: C

Rationale: The correct answer is C. Oral contraceptives can be less effective when taken with certain antibiotics due to potential drug interactions. It is crucial for patients to be informed about this to consider additional contraceptive methods during antibiotic therapy. Choice A is incorrect because while oral contraceptives are highly effective, they are not 100% foolproof. Choice B is incorrect as it may give the impression that immediate protection is conferred, which is not the case. Choice D is incorrect as taking oral contraceptives with food does not significantly impact their effectiveness.
