Nursing Elites

1. Which dietary supplement is often recommended for patients taking statins to lower cholesterol?

• A. Iron
• B. Coenzyme Q10
• C. Calcium
• D. Magnesium

Correct answer: B

Rationale: Coenzyme Q10 is often recommended for patients on statins because it may help reduce muscle pain, a common side effect of these medications. Iron (Choice A) is not typically recommended for patients taking statins to lower cholesterol. Calcium (Choice C) and Magnesium (Choice D) are not specifically indicated for addressing muscle pain associated with statin use, making them less suitable choices in this scenario.

2. Select all that apply. Characteristics of the 2 main types of essential fatty acids discussed in class include:

• A. they must be supplied by the diet
• B. they can be produced by a process called dehydrogenation
• C. they are anti-inflammatory
• D. they are all polyunsaturated fatty acids

Correct answer: A

Rationale: The correct answer is A: 'they must be supplied by the diet.' Essential fatty acids, like omega-3 and omega-6, cannot be produced by the body and must be obtained through the diet. They are polyunsaturated fatty acids, playing vital roles in inflammation and cell membrane structure. Choice B is incorrect because essential fatty acids cannot be produced by dehydrogenation, a process of removing hydrogen. Choice C is incorrect as not all essential fatty acids are anti-inflammatory; some have pro-inflammatory roles. Choice D is incorrect because not all essential fatty acids are polyunsaturated; omega-9, for example, is a monounsaturated essential fatty acid.

3. What describes a criterion used to diagnose diabetes?

• A. a plasma glucose concentration of 100 mg/dL or higher after a fast of at least 12 hours
• B. a casual blood sample of 200 mg/dL or higher in a person with classic symptoms
• C. a plasma glucose concentration measured two hours after a 200-gram glucose load is 400 mg/dL or higher
• D. a HbA1C higher than 5 percent

Correct answer: B

Rationale: A casual blood sample of 200 mg/dL or higher in a person with classic symptoms is a diagnostic criterion for diabetes. This choice aligns with the typical clinical presentation of diabetes and is a key diagnostic indicator. Choices A, C, and D do not accurately reflect the established criteria for diagnosing diabetes, making them incorrect. Choice A pertains to a fasting plasma glucose level, Choice C involves a glucose challenge test, and Choice D refers to HbA1C levels, which are used for monitoring blood sugar control over time, not for diagnosing diabetes.

4. Which mineral is a principal component of cell membranes?

• A. phosphorus
• B. magnesium
• C. iron
• D. iodine

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

5. After a vaginal examination, the nurse determines that the client’s fetus is in an occiput posterior position. The nurse would anticipate that the client will have:

• A. A precipitous birth
• B. Intense back pain
• C. Frequent leg cramps
• D. Nausea and vomiting

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
