ATI Nutrition Proctored Exam 2019 Answers
1. What are dextrins?
- A. Polysaccharides.
- B. End products of starch digestion.
- C. Formed in the liver.
- D. Rapidly excreted.
Correct answer: A
Rationale: Dextrins are a type of polysaccharides formed during the breakdown of starch. Choice A is correct because dextrins are indeed polysaccharides, not the end products of starch digestion (Choice B). They are not formed in the liver (Choice C) nor rapidly excreted (Choice D).
2. A client with atrial fibrillation is prescribed warfarin (Coumadin). Which instruction should the nurse give to the client regarding lifestyle changes?
- A. Avoid prolonged sitting or standing.
- B. Use an electric razor to prevent cuts.
- C. Take your medication with a full glass of water.
- D. Eat a diet low in protein.
Correct answer: B
Rationale: The correct answer is B. Using an electric razor is advised to prevent cuts, which is crucial for individuals taking warfarin due to the increased risk of bleeding associated with this medication. Lifestyle changes related to warfarin therapy focus on minimizing the risk of bleeding, and using safety measures such as an electric razor is a practical recommendation to reduce the likelihood of injury. Choices A, C, and D are incorrect. Avoiding prolonged sitting or standing is more related to preventing blood clots than to the bleeding risk of warfarin. Taking warfarin with a full glass of water is not a specific lifestyle change associated with its use. Eating a diet low in protein is not a typical recommendation for individuals on warfarin therapy.
3. A nurse is caring for a client who has an indwelling urinary catheter. What should the nurse identify as a catheter occlusion?
- A. Pain during urination
- B. Bladder distention
- C. Cloudy urine
- D. Blood in the catheter tube
Correct answer: B
Rationale: The correct answer is B: Bladder distention. Bladder distention indicates that the bladder is full and there is impaired elimination, which could be caused by catheter occlusion. Pain during urination (choice A) is not typically associated with catheter occlusion but may indicate a urinary tract infection. Cloudy urine (choice C) can be a sign of infection but is not specific to catheter occlusion. Blood in the catheter tube (choice D) may indicate trauma during catheter insertion but is not a typical finding in catheter occlusion.
4. What are the key signs of hyperkalemia and how should it be treated?
- A. Elevated potassium levels, muscle weakness; administer calcium gluconate
- B. Decreased potassium levels, confusion; administer potassium chloride
- C. Elevated sodium levels, bradycardia; administer sodium bicarbonate
- D. Low sodium levels, muscle cramps; administer sodium chloride
Correct answer: A
Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.
5. A nurse is sitting with the partner of a client who recently died. Which of the following actions should the nurse take to facilitate mourning?
- A. Encourage the partner to ask for help when needed
- B. Suggest the partner avoid discussing their feelings
- C. Recommend immediate return to daily activities
- D. Advise the partner to remain strong
Correct answer: A
Rationale: The correct action for the nurse to take to facilitate mourning is to encourage the partner to ask for help when needed. Grieving is a challenging process, and offering support and encouragement to seek help can be beneficial. Choice B is incorrect because avoiding discussing feelings can hinder the grieving process by suppressing emotions. Choice C is also incorrect as an immediate return to daily activities may not allow the partner to properly process their grief. Choice D is not the best approach as advising the partner to 'remain strong' may discourage the expression of emotions and seeking support, which are essential in the mourning process.
