Critical Care Nursing Questions

Correct Answer: B

Rationale: The correct answer is B because it acknowledges and validates the patient's belief, showing empathy and support. By stating that the belief gives strength, the nurse facilitates a therapeutic relationship and promotes the patient's emotional well-being. Choice A is incorrect as it challenges the patient's belief system, potentially creating conflict. Choice C is inappropriate as it dismisses the patient's belief and could damage the nurse-patient relationship. Choice D is also incorrect as it invalidates the patient's belief and could harm trust and rapport.

Correct Answer: B

Rationale: The correct answer is B: Zero reference the transducer system at the phlebostatic axis. This is the most important action before obtaining a cardiac output because zero referencing ensures accurate pressure readings. The phlebostatic axis is the level of the atria when the patient is supine, and zeroing at this point minimizes errors in pressure measurements. Choice A is incorrect because documenting a pulmonary artery catheter occlusion pressure is not the priority at this stage. Choice C is incorrect as inflating the balloon with air should be done after zero referencing. Choice D is incorrect as injecting normal saline into the port is not necessary before zero referencing.

Correct Answer: B

Rationale: The correct answer is B because calibrating the system with central venous and arterial blood samples ensures accuracy of the mixed venous oxygen saturation (SvO2) measurement. This calibration allows for comparison of the values obtained from both sources to confirm the accuracy of the measurement. Choice A is incorrect because zero referencing the transducer at the level of the phlebostatic axis does not directly address the accuracy of the SvO2 measurement. Choice C is incorrect because ensuring patency of the catheter using normal saline pressurized at 300 mm Hg does not directly impact the accuracy of the SvO2 measurement. Choice D is incorrect because using noncompliant pressure tubing does not ensure the accuracy of the SvO2 measurement. The length of the tubing and the presence of stopcocks are not directly related to obtaining an accurate SvO2 value.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Family-centered care promotes involvement of family members in patient care. 2. A sleeper sofa in the patient's room allows family members to stay overnight, enhancing support for the patient. 3. Storage for personal belongings ensures families can have essentials close by, increasing comfort and convenience. 4. These design elements facilitate family presence, communication, and participation in care, aligning with family-centered care principles. Summary of Incorrect Choices: B. Having a diagnostic suite nearby is convenient but not directly related to family-centered care principles. C. A waiting room with amenities is beneficial but does not directly involve families in patient care. D. Access to a garden for meditation is helpful for relaxation but does not emphasize family involvement in care.

Correct Answer: D

Rationale: Step 1: Abdominal pain, chills, and elevated temperature suggest a serious complication like visceral perforation. Step 2: Peritoneal dialysate return assessment won't address the potential life-threatening issue. Step 3: Checking blood sugar or evaluating neurological status is not relevant to the presenting symptoms. Step 4: Informing the provider of probable visceral perforation is crucial for prompt intervention and further evaluation.
