The critical care nurse knows that in critically ill patients, renal dysfunction
- A. is a very rare problem.
- B. affects nearly two thirds of patients.
- C. has a low mortality rate once renal replacement therapy has been initiated.
- D. has little effect on morbidity, mortality, or quality of life.
Correct Answer: B
Rationale: The correct answer is B. Renal dysfunction is common in critically ill patients due to various factors like sepsis, hypotension, and nephrotoxic medications. This affects nearly two thirds of patients, making it a significant issue in critical care. Choices A, C, and D are incorrect. A is wrong because renal dysfunction is not rare in critically ill patients. C is incorrect as renal replacement therapy does not guarantee low mortality rates. D is inaccurate as renal dysfunction can have a significant impact on morbidity, mortality, and quality of life in critically ill patients.

The nurse is preparing to obtain a right atrial pressure (RA P/CVP) reading. What are the most appropriate nursing actions? (Select all that apply.)
- A. Compare measured pressures with other physiological parameters.
- B. Flush the central venous catheter with 20 mL of sterile saline.
- C. Inflate the balloon with 3 mL of air and record the pres sure tracing.
- D. Obtain the right atrial pressure measurement during en d exhalation.
Correct Answer: A
Rationale: The correct answer is A because comparing measured pressures with other physiological parameters ensures accuracy and consistency. This step helps in interpreting the RA P/CVP reading correctly. Choice B is incorrect as flushing the catheter with saline is not necessary for obtaining the pressure reading. Choice C is incorrect as inflating the balloon with air is not part of the correct procedure. Choice D is incorrect because obtaining the measurement during exhalation can affect the accuracy of the reading.
The transplant clinic coordinator is evaluating relatives of a patient with end-stage renal disease, whose blood type is A positive, for suitability as aa bliirvb.icnogm /dteostn or for kidney transplantation. Which family member best qualifies for evaluation?
- A. A 65-year-old brother with a history of hypertension; b lood type A positive
- B. A 35-year-old female with a history of food allergies; blood type O negative
- C. A 14-year-old son, otherwise healthy with no history; blood type B negative
- D. A 70-year-old mother, with a history of sinus infection s; blood type A positive
Correct Answer: D
Rationale: The correct answer is D, the 70-year-old mother with blood type A positive. This choice is the best candidate for evaluation due to her blood type matching the patient's (A positive) for kidney transplantation. Age and medical history are also crucial factors in determining suitability. The 65-year-old brother (choice A) has hypertension, a significant risk factor. The 35-year-old female (choice B) with food allergies may have potential complications. The 14-year-old son (choice C) is underage and might not be a suitable donor due to age and the potential impact on his growth and development. In summary, choice D aligns with the matching blood type and age, making the mother the most suitable candidate for evaluation.
The nurse is caring for a postoperative patient in the critica l care unit. The physician has ordered patient-controlled analgesia (PCA) for the patient. The nurse understands what facts about the PCA? (Select all that apply.)
- A. It is a safe and effective method for administering anal gesia.
- B. It has potentially fewer side effects than other routes of analgesic administration.
- C. It is an ideal method to provide critically ill patients so me control over their treatment.
- D. It does not work well without family assistance
Correct Answer: A
Rationale: Step-by-step rationale for why Answer A is correct:
1. Patient-controlled analgesia (PCA) allows patients to self-administer pain medication within preset limits, promoting pain management.
2. PCA is considered safe and effective as it provides better pain control, reduces the risk of overdose, and allows for individualized dosing.
3. Healthcare providers can monitor and adjust the PCA settings as needed to ensure optimal pain relief.
4. Studies have shown that PCA is a preferred method for postoperative pain management due to its efficacy and safety profile.
5. Overall, PCA is a reliable and beneficial approach to analgesia administration in postoperative patients.
Summary of why other choices are incorrect:
B: While PCA may have fewer side effects compared to some routes, this is not a defining characteristic of PCA.
C: While patients do have some control over their treatment with PCA, the primary focus is on pain management rather than giving control to critically ill patients.
D: PCA can be used effectively without family
The nurse wishes to increase the use of evidence-based practice in the critical care unit where he works. What is a significant barrier to the implementation of evidence-based practice?
- A. Use of computerized records by the hospital
- B. Health Information Privacy and Portability Act (HIPPA)
- C. Lack of knowledge about literature searches
- D. Strong collaborative relationships in the work setting
Correct Answer: C
Rationale: Rationale:
The correct answer is C because lack of knowledge about literature searches hinders the ability to find and utilize evidence-based practice guidelines. Nurses need to be skilled in conducting literature searches to access relevant research. Choices A, B, and D are incorrect as they do not directly impede the implementation of evidence-based practice in the critical care unit.
What is the most important outcome of effective communi cation?
- A. Demonstrating caring practices to family members.
- B. Ensuring that patient teaching is provided
- C. Meeting the diversity needs of patients.
- D. Reducing patient errors.
Correct Answer: D
Rationale: The correct answer is D because reducing patient errors is the most important outcome of effective communication in healthcare. Clear and accurate communication among healthcare providers and patients can prevent misunderstandings, leading to fewer errors in diagnosis, treatment, and medication administration. This ultimately improves patient safety and outcomes.
A: Demonstrating caring practices to family members is important but not the most crucial outcome of effective communication in healthcare.
B: Ensuring that patient teaching is provided is essential, but patient safety through error reduction takes precedence.
C: Meeting the diversity needs of patients is crucial for patient-centered care, but error reduction directly impacts patient safety, making it more critical.
