Critical Care Nursing Practice Questions

Correct Answer: D

Rationale: The correct answer is D: Attach cardiac monitoring leads before the procedure. This is essential to monitor the patient's cardiac rhythm and detect any abnormalities during catheter insertion. Cardiac monitoring leads provide real-time information on the patient's heart rate and rhythm, allowing the nurse to promptly address any complications. A: Determining if the cardiac troponin level is elevated is not directly related to assisting with pulmonary artery catheter insertion. B: Auscultating heart and breath sounds during insertion is important but does not take precedence over attaching cardiac monitoring leads. C: Placing the patient on NPO status before the procedure may be necessary for other procedures, but it is not specifically required for assisting with pulmonary artery catheter insertion.

Correct Answer: D

Rationale: The correct answer is D: Increased confidence in critical thinking. Achieving certification in critical care nursing validates the nurse's expertise and knowledge in this specialized area, leading to increased confidence in their ability to critically think through complex patient situations. This confidence translates into improved clinical decision-making and patient outcomes. A: Recognition by peers - While recognition by peers is important for professional growth, the primary benefit of certification is enhancing clinical skills. B: Increase in salary and rank - While certification may lead to salary increases in some cases, the most significant impact is on improving clinical skills. C: More flexibility in seeking employment - While certification may enhance employability, the focus is on improving critical thinking skills rather than employment opportunities.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Bladder catheterization helps relieve urinary obstruction, a common postrenal cause of acute kidney injury. 2. By draining urine from the bladder, it prevents further damage to the kidneys. 3. This intervention addresses the underlying cause of the kidney injury, leading to improvement. Summary: - Choice A is correct as it directly addresses the postrenal cause by relieving urinary obstruction. - Choices B, C, and D are incorrect as they do not target the specific postrenal cause of acute kidney injury.

Correct Answer: B

Rationale: The correct answer is B because peritoneal dialysis utilizes the patient's own semipermeable membrane, the peritoneal membrane, as the filtration surface. This allows for the exchange of waste products and excess fluids without the need for external dialysis equipment. Choice A is incorrect as peritoneal dialysis can be used for both acute and chronic kidney injury. Choice C is incorrect as peritoneal dialysis can help manage drug overdose and electrolyte imbalances. Choice D is incorrect as peritoneal dialysis can be used in cases of water intoxication to help remove excess fluids.

Correct Answer: A

Rationale: The correct answer is A because this patient had a complex surgery with complications, requiring long-term care and loss of a significant other, which can impact their emotional well-being and support system. This can lead to decreased functional status and quality of life. Choice B is incorrect as the patient has support from a spouse and manages health care independently, indicating a good support system. Choice C is incorrect as the patient is cognitively intact and social, which suggests a good quality of life. Choice D is incorrect as the patient had a less complex procedure, well-managed diabetes, and was living independently, which indicates a lower risk for decreased functional status and quality of life compared to choice A.
