Nursing Elites

1. 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.

2. A client had a C5 spinal cord contusion that resulted in quadriplegia. Two days after the injury occurred, the nurse sees his mother crying in the waiting room. The mother asks the nurse whether her son will ever play football again. Which of the following is the best initial response?

• A. “Given time and motivation, your son may regain some function, but I will seek more information from the physician.”
• B. Maintain a calm demeanor and speech pattern while addressing the mother's concerns.
• C. “I’m not sure, but I’ll call the physician to discuss this with you promptly.”
• D. “It's not beneficial for your son if you get upset.”

Correct answer: “I’m not sure, but I’ll call the physician to discuss this with you promptly.”

Rationale: The best initial response in this situation is to acknowledge the mother's concern, express uncertainty, and offer to obtain more information from the physician. By saying, “I’m not sure, but I’ll call the physician to discuss this with you promptly,” the nurse demonstrates empathy, honesty, and a commitment to providing accurate information. Offering vague reassurance (Choice A) may raise false hopes as outcomes for spinal cord injuries are unpredictable. While maintaining a calm demeanor (Choice B) is important, it does not directly address the mother's immediate need for information. Discouraging the mother from feeling upset (Choice D) is dismissive of her emotions and does not address her question, which is seeking information about her son's prognosis.

3. A nurse at an outpatient clinic is returning phone calls that have been made to the clinic. Which of the following calls should have the highest priority for medical intervention?

• A. A home health patient reports, “I am starting to have a breakdown of my heels.”
• B. A patient that received an upper extremity cast yesterday reports, “I can’t feel my fingers in my right hand today.”
• C. A young female reports, 'I think I sprained my ankle about 2 weeks ago.'
• D. A middle-aged patient reports, 'My knee is still hurting from the TKR.'

Correct answer: A patient that received an upper extremity cast yesterday reports, “I can’t feel my fingers in my right hand today.”

Rationale: The correct answer is the patient who received an upper extremity cast yesterday and reports not being able to feel their fingers in the right hand. This situation indicates a potential neurovascular issue that requires immediate attention to prevent complications. The other options are of lesser priority: A - Breakdown of the heels, while concerning, is not an acute issue that necessitates immediate intervention. C - An ankle sprain that occurred two weeks ago is now subacute and unlikely to be an urgent medical concern. D - Pain in the knee following a total knee replacement (TKR) is common in the early postoperative period and is not unexpected.

4. The client with ulcerative colitis calls the clinic and reports increasing abdominal pain and increased frequency of loose stools. He asks to clarify what type of diet he is to follow. Which diet is best for clients with ulcerative colitis?

• A. High vitamin
• B. High calorie
• C. Low sugar
• D. Low fiber

Correct answer: D

Rationale: The correct answer is 'Low fiber.' Clients with ulcerative colitis should follow a low-residue diet, which means consuming low fiber to reduce the frequency and volume of stools, helping to alleviate symptoms such as abdominal pain and diarrhea. High fiber diets can worsen the condition by stimulating bowel movements. Choice A, 'High vitamin,' is incorrect as the focus is on fiber content rather than vitamins. Choice B, 'High calorie,' is not specifically recommended for ulcerative colitis and may not address the symptoms effectively. Choice C, 'Low sugar,' does not directly address the dietary needs of clients with ulcerative colitis as the issue is more related to fiber intake than sugar consumption.

5. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

• A. It protects the bacteria from antibiotic and immunologic destruction.
• B. Glycocalyx neutralizes the antibiotic, rendering it ineffective.
• C. It competes with the antibiotic for binding sites on the microbe.
• D. Glycocalyx provides nutrients for microbial growth.

Correct answer: It protects the bacteria from antibiotic and immunologic destruction.

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.
