Conditions that produce acute kidney injury by directly acting on functioning kidney tissue are classified as intrarenal. The most common intrarenal condition is
- A. prolonged ischemia.
- B. exposure to nephrotoxic substances.
- C. acute tubular necrosis (ATN).
- D. hypotension for several hours.
Correct Answer: C
Rationale: Rationale:
1. Acute tubular necrosis (ATN) is the most common intrarenal condition as it directly affects kidney tubules.
2. ATN is characterized by damage to renal tubular cells due to various factors like toxins or ischemia.
3. Prolonged ischemia (choice A) can lead to ATN but is not the most common intrarenal condition.
4. Exposure to nephrotoxic substances (choice B) can cause ATN, but ATN itself is more common.
5. Hypotension for several hours (choice D) can result in ischemia and subsequent ATN, but ATN is still the primary intrarenal condition.

In determining the glomerular filtration rate (GFR) or creatinine clearance, a 24-hour urine is obtained. If a reliable 24-hour urine collection is not possible,
- A. it is not possible to determine the GFR.
- B. the BUN may be used to determine renal function.
- C. an elevated BUN/creatinine ratio can be used.
- D. a standardized formula may be used to calculate GFR.
Correct Answer: D
Rationale: The correct answer is D because when a reliable 24-hour urine collection is not possible, a standardized formula can be used to estimate GFR. The Cockcroft-Gault equation or the Modification of Diet in Renal Disease (MDRD) equation are commonly used formulas to estimate GFR based on serum creatinine levels, age, gender, and race. These formulas provide a reasonable estimation of kidney function in the absence of a 24-hour urine collection.
Choice A is incorrect because there are alternative methods available to estimate GFR. Choice B is incorrect because BUN alone is not sufficient to accurately determine renal function. Choice C is incorrect because an elevated BUN/creatinine ratio is not a direct measure of GFR and may be influenced by factors other than kidney function, such as hydration status or liver function.
A Muslim woman is admitted to the ICU after suffering severe burns over most of her body. Which of the following would be the most appropriate measure for the nurse, a woman, to take in respect for the cultural practices of this patient?
- A. Insist that only a female doctor be assigned to this patient.
- B. Ensure that no pork products are included in the patients diet.
- C. Ensure that direct eye contact is not made with the patients husband.
- D. Ask the patients husband what religious and cultural preferences should be considered in the patients care.
Correct Answer: D
Rationale: The correct answer is D because it demonstrates respect for the patient's autonomy and individual preferences. By asking the patient's husband about religious and cultural preferences, the nurse acknowledges the importance of involving the family in decision-making and shows sensitivity to the patient's beliefs. This approach promotes cultural competence and patient-centered care.
Choice A is incorrect because insisting on a female doctor may not align with the patient's preferences and may limit the available medical staff. Choice B is also incorrect as dietary restrictions are not necessarily the most pressing issue in this scenario. Choice C is incorrect as it assumes a cultural practice without verifying the patient's specific preferences and may not be necessary or appropriate in this context.
A patient is declared brain dead and a do not resuscitate (DNR) order is put in place. The nurse caring for the patient does not agree with this manne r of care but does not express any concerns to the charge nurse. The nurse’s feeling that the p atient is being killed will likely create what response for this nurse?
- A. A sense of abandonment
- B. Increased family stress
- C. Moral distress
- D. A sense of negligence
Correct Answer: C
Rationale: The correct answer is C: Moral distress. In this scenario, the nurse is experiencing conflicting moral values between the decision made for the patient and their own beliefs. This internal conflict leads to moral distress, a common response when healthcare professionals feel unable to act in accordance with their ethical beliefs. This can lead to emotional turmoil, frustration, and moral residue.
A: A sense of abandonment is incorrect because the nurse is still caring for the patient, so there is no physical abandonment.
B: Increased family stress is incorrect as the nurse's internal conflict does not directly impact family stress.
D: A sense of negligence is incorrect as negligence implies failure to provide proper care, which is not the case here.
A male client is angry and is leaving the hospital against medical advice (AMA). The client demands to take his chart with him and states the chart is 'his' and he doesn’t want any more contact with the hospital. How should the nurse respond?
- A. This hospital does not need to keep it if you are leaving and not returning here.
- B. Because you are leaving against medical advice, you may not have your chart.
- C. The information in your chart is confidential and cannot leave this facility legally.
- D. The chart is the property of the hospital but I will see that a copy is made for you.
Correct Answer: D
Rationale: The correct answer is D because the client's medical chart is the property of the hospital, but the client has the right to a copy of the information. By offering to make a copy of the chart for the client, the nurse respects the client's autonomy while also ensuring that the hospital maintains the original medical record. This response balances the client's rights with legal and ethical considerations.
Choice A is incorrect because the hospital is legally obligated to maintain the client's medical record even if the client leaves against medical advice. Choice B is incorrect as it denies the client access to their medical information, which goes against the principle of patient autonomy. Choice C is also incorrect as it does not address the client's request for a copy of their chart.
A nurse is caring for an elderly man recently admitted to the ICU following a stroke. She assesses his cognitive function using a new cognitive assessment test she learned about in a recent article in a nursing journal. She then brings a cup of water and a straw to the patient because she observes that his lips are dry. Later, she has the patient sit in a wheelchair and takes him to have some blood tests performed. He objects at first, saying that he can walk on his own, but the nurse explains that it is hospital policy to use the wheelchair. That evening, she recognizes signs of an imminent stroke in the patient and immediately pages the physician. Which action taken by the nurse is the best example of evidence-based practice?
- A. Giving the patient a cup of water
- B. Transferring the patient in a wheelchair
- C. Recognizing signs of imminent stroke and paging the physician
- D. Using the cognitive assessment test
Correct Answer: C
Rationale: The correct answer is C: Recognizing signs of an imminent stroke and paging the physician. This action exemplifies evidence-based practice as it involves timely identification of a critical medical condition based on clinical assessment and prompt communication with the physician for further intervention. This aligns with the principles of evidence-based practice, which emphasize the integration of best available evidence with clinical expertise and patient values.
The other choices are incorrect:
A: Giving the patient a cup of water - While providing hydration is important for patient care, it does not demonstrate evidence-based practice in this scenario.
B: Transferring the patient in a wheelchair - Although using a wheelchair may be hospital policy, it does not directly relate to evidence-based practice in this context.
D: Using the cognitive assessment test - While assessing cognitive function is essential, it does not directly address the immediate medical needs of the patient as recognizing signs of an imminent stroke does.
