Nursing Elites

1. Which of the following foods is the best source of omega-3 fatty acids?

• A. Salmon
• B. Chicken
• C. Spinach
• D. Eggs

Correct answer: A

Rationale: Salmon is the correct answer as it is a rich source of omega-3 fatty acids, specifically EPA and DHA, which are known to be beneficial for heart health. Chicken, spinach, and eggs do not contain significant levels of omega-3 fatty acids compared to salmon. While eggs do contain some omega-3s, the amount is considerably lower than what is found in fatty fish like salmon.

2. Which cells in the islet of the pancreas are responsible for synthesizing insulin?

• A. Alpha cells
• B. Beta cells
• C. Gamma cells
• D. Delta cells

Correct answer: B

Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.

3. Which type of fatty acid has carbon atoms connected by two or more double bonds?

• A. Saturated fatty acids
• B. Monounsaturated fatty acids
• C. Trans fatty acids
• D. Polyunsaturated fatty acids

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.

4. The RR nurse should monitor for the most common postoperative complication of:

• A. hemorrhage
• B. endotracheal tube perforation
• C. osopharyngeal edema
• D. epiglottis

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.

5. Instruction on health promotion regarding urinary elimination is important. Which would you include?

• A. Hold urine as long as possible before emptying the bladder to strengthen the sphincter muscles
• B. If a burning sensation is experienced while voiding, drink water
• C. After urination, wipe from the anal area towards the pubis
• D. Tell the client to empty the bladder at each voiding

Correct answer: D

Rationale: The correct answer is to instruct the client to empty the bladder at each voiding. This is essential to prevent urinary retention and reduce the risk of urinary tract infections. Choice A is incorrect because holding urine for prolonged periods can lead to urinary retention and increase the risk of infections. Choice B is incorrect as pineapple juice can exacerbate a burning sensation due to its acidity; the correct approach is to drink water to dilute the urine. Choice C is incorrect as wiping from the anal area towards the pubis can introduce bacteria into the urinary tract, potentially causing infections.
