Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B: Disconnect the flush system from the arterial line catheter. This action is necessary to prevent air from entering the patient's bloodstream, which can lead to air embolism. By disconnecting the flush system, the nurse stops the flow of air and ensures patient safety. Checking the inflation volume of the pressurized bag (A) is not the immediate concern in this situation. Zero referencing the transducer system (C) is unrelated to the issue of air entering the arterial line. Reducing the number of stopcocks in the flush system tubing (D) does not address the immediate risk of air embolism.

Correct Answer: A

Rationale: The correct answer is A because assessing the patient and family's developmental stages and needs is crucial in understanding their current situation and determining the appropriate care plan. By assessing developmental stages, the nurse can tailor interventions to meet the family's specific needs. This assessment also helps in identifying potential challenges or areas requiring support. Choice B is incorrect as it focuses solely on the physical environment and does not address the family's developmental stages and needs. Choice C is incorrect as it emphasizes identifying family members without considering the importance of understanding their developmental stages and needs in providing family-centered care. Choice D is incorrect as it concentrates on family dynamics without directly addressing the crucial aspect of assessing developmental stages and needs for effective family-centered care.

Correct Answer: B

Rationale: The correct answer is B because developing a standardized reporting form for family information that is incorporated into the patient's medical record ensures consistency and accuracy in sharing vital details about family structure and dynamics from shift to shift. This method allows all healthcare providers to access the information easily and update it as needed, promoting continuity of care and comprehensive understanding of the family's needs. Choices A, C, and D are incorrect because: A: Creating an informal family information sheet may lead to inconsistencies in the information shared among healthcare providers and may not be updated regularly. C: Requiring only the charge nurse to have detailed information may result in information silos and lack of accessibility for all team members. D: Discussing family dynamics as part of the change-of-shift report may lead to important details being missed or forgotten, compromising the quality of care provided.

Correct Answer: D

Rationale: Ultrafiltration is the correct answer because it involves the removal of plasma water and low-molecular weight particles by using a pressure or osmotic gradient. During ultrafiltration, the pressure gradient pushes the fluid through a semipermeable membrane, separating the substances based on their molecular size. This process allows for the selective removal of unwanted substances while retaining essential components. Dialysis (choice A) involves the removal of waste products from the blood, but it does not specifically target plasma water and low-molecular weight particles. Diffusion (choice B) is the passive movement of particles from an area of higher concentration to an area of lower concentration and is not specific to the removal of plasma water. Clearance (choice C) refers to the rate at which a substance is removed from the blood and does not involve the mechanism of pressure or osmotic gradient utilized in ultrafiltration.

Correct Answer: A

Rationale: The correct answer is A: A patient with a red tag. In triage, red tags indicate patients with life-threatening injuries who require immediate attention. The nurse must assess this patient first to provide necessary interventions. Patients with blue tags are considered urgent but stable, black tags are deceased or beyond help, and yellow tags are for delayed treatment. Assessing the red-tagged patient first ensures prompt care for those in critical condition.
