What is the most common cause of acute renal failure?
- A. Shock
- B. Nephrotoxic drugs
- C. Enlarged prostate
- D. Diabetes
Correct Answer: A
Rationale: The correct answer is 'Shock.' Acute renal failure is commonly caused by inadequate blood flow to the kidneys, which can occur in cases of shock. This leads to decreased kidney function and potential kidney damage. While nephrotoxic drugs can also cause acute renal failure, shock is the primary and most common cause. An enlarged prostate may lead to obstructive uropathy but is not the most prevalent cause of acute renal failure. Diabetes is typically associated with chronic kidney disease rather than acute renal failure.

Post thyroidectomy the nurse assesses for complications by performing which of the following assessments?
- A. Accu-Chek
- B. Chvostek's
- C. Ballottement
- D. Ice water colonic
Correct Answer: B
Rationale: The correct answer is Chvostek's. A positive Chvostek's and Trousseau's sign is indicative of tetany, which is associated with low calcium levels. This can occur if parathyroid glands are accidentally removed during thyroidectomy. Accu-Chek is a brand of blood glucose monitor used for checking blood sugar levels and is not relevant in this context. Ballottement is a technique used in physical examination to assess for fluid in the body, typically in the abdomen or joints. Ice water colonic is not a standard medical assessment and is not relevant to post-thyroidectomy complications.
A 70-year-old male who is recovering from a stroke exhibits signs of unilateral neglect. Which behavior is suggestive of unilateral neglect?
- A. The client is observed shaving only one side of his face.
- B. The client is unable to distinguish between two tactile stimuli presented simultaneously.
- C. The client is unable to complete a range of vision without turning his head side to side.
- D. The client is unable to carry out cognitive and motor activity at the same time.
Correct Answer: A
Rationale: Unilateral neglect is a condition where a person ignores one side of their body. In this case, the behavior of shaving only one side of the face indicates neglect of the other side. This behavior is suggestive of unilateral neglect as the individual is failing to attend to one side of their body. Choices B, C, and D are not associated with unilateral neglect. Choice B refers to tactile agnosia, a condition where a person cannot recognize objects by touch, not related to ignoring one side of the body. Choice C describes a visual field cut, which is a different visual deficit. Choice D relates to dual-task interference, not specific to ignoring one side of the body.
The nurse is teaching a community health class for cancer prevention and screening. Which individual has the highest risk for colon cancer?
- A. Client with irritable bowel syndrome
- B. Family history of colon polyps
- C. Client with cirrhosis of the liver
- D. History of colon surgery
Correct Answer: B
Rationale: A family history of colon polyps and/or colon cancer is a significant risk factor for developing colon cancer. Individuals with a family history are more likely to develop colon cancer due to genetic predisposition. While other factors like irritable bowel syndrome, cirrhosis of the liver, and history of colon surgery may contribute to an increased risk of colon cancer, having a family history of colon polyps is the highest risk factor. Irritable bowel syndrome does not directly increase the risk of colon cancer. Cirrhosis of the liver is associated with liver cancer rather than colon cancer. A history of colon surgery may reduce the risk of colon cancer in some cases by removing precancerous polyps.
What vitamin is important in preventing peripheral neuritis in a client with alcohol abuse?
- A. Vitamin D
- B. Fat-soluble vitamins
- C. B vitamins
- D. Potassium
Correct Answer: B
Rationale: The correct answer is 'Fat-soluble vitamins.' Vitamin B, not Vitamin D, is crucial in preventing peripheral neuritis in individuals with alcohol abuse. Vitamin B deficiency, particularly B1 (thiamine), is commonly associated with peripheral neuritis in alcoholics. Therefore, choices A, C, and D are incorrect. Vitamin D is not directly related to peripheral neuritis, and potassium deficiency typically presents with different symptoms.
After discontinuing a peripherally inserted central line (PICC), what information is most important for the nurse to record?
- A. How the client tolerated the procedure.
- B. The length and intactness of the central line catheter.
- C. The amount of fluid left in the IV solution container.
- D. That a dressing was applied to the insertion site.
Correct Answer: B
Rationale: The most important information for the nurse to record after discontinuing a peripherally inserted central line (PICC) is the length and intactness of the central line catheter. This is crucial for assessing any potential complications or safety issues post-removal. Choices A, C, and D are not as critical as ensuring the condition of the central line catheter. While noting the client's tolerance of the procedure is relevant for their care assessment, evaluating the central line's integrity takes precedence in this scenario.
