1. 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. Polyunsaturated fatty acids
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.
2. 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.
3. 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.
4. All of the following are instructions for proper foot care to be given to a client with peripheral vascular disease caused by diabetes. Which one is not?
- A. Trim nails using a nail clipper
- B. Apply cornstarch to the foot
- C. Always check the temperature of the water before bathing
- D. Use canvas shoes
Correct answer: A
Rationale: The correct answer is 'A', which says trim nails using a nail clipper. This is incorrect because patients with peripheral vascular disease, particularly those caused by diabetes, should not trim their nails themselves due to the risk of injury, infection, and poor wound healing. The other options, 'B', 'C', and 'D', are correct advice for diabetic foot care. Applying cornstarch can help keep the feet dry and prevent fungal infections. Checking the water temperature before bathing can prevent burns, as patients with peripheral vascular disease often have decreased sensation in their feet. Wearing canvas shoes can improve foot ventilation and reduce the risk of foot ulcers and infections.
5. In obtaining a urine specimen for culture and sensitivity on a catheterized patient, the nurse is correct if:
- A. Clamp the catheter for 30 minutes, Alcoholize the tube above the clamp site, Obtain a sterile syringe and draw the
- B. Alcoholize the self sealing port, obtain a sterile syringe and draw the specimen on the self sealing port
- C. Disconnect the drainage bag, obtain a sterile syringe and draw the specimen from the drainage bag
- D. Disconnect the tube, obtain a sterile syringe and draw the specimen from the tube
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.
