Critical Care Nursing Questions and Answers PDF

Correct Answer: D

Rationale: The correct answer is D because continuous venovenous hemodialysis combines ultrafiltration, convection, and dialysis techniques. Ultrafiltration removes excess fluid, convection helps in removing solutes, and dialysis involves the diffusion of solutes across a semipermeable membrane. This comprehensive approach ensures effective removal of both fluid and solutes in critically ill patients. Incorrect Answer Analysis: A: Removing fluids and solutes through convection alone is not the complete process in continuous venovenous hemodialysis. B: While volume overload is addressed, continuous venovenous hemodialysis involves more than just removing plasma water. C: Adding dialysate is not the primary method in continuous venovenous hemodialysis; it involves ultrafiltration, convection, and dialysis techniques.

Correct Answer: C

Rationale: The correct answer is C: Anxiety related to lack of knowledge about normal grieving. This is because the patient is expressing uncertainty and seeking validation for their feelings, indicating a lack of understanding about the grieving process. Choice A is incorrect as hopelessness typically involves feelings of despair and loss of motivation, which are not explicitly stated by the patient. Choice B is incorrect as complicated grieving involves specific unresolved issues related to the loss, which the patient did not mention. Choice D is incorrect as chronic sorrow is typically associated with ongoing feelings of sadness and longing, which are not explicitly expressed by the patient.

Correct Answer: B

Rationale: The correct answer is B: Contact the hospital�s interpreter service for someone to translate. This is the best option as it ensures accurate communication between the nurse, patient, and family. Hospital interpreters are trained professionals who can accurately convey medical information, ensuring understanding and informed decision-making. Using Google search (A) may result in inaccurate information and is not reliable for medical communication. Asking a resident (C) who is fluent may not guarantee accuracy in medical terminology. Using a young family member (D) as a translator can lead to miscommunication due to potential language barriers or lack of medical knowledge. Overall, option B is the most appropriate and ethical choice for effective communication in a healthcare setting.

Correct Answer: A

Rationale: The correct answer is A, absence of a corneal reflex, because in brain death, all brainstem reflexes, including the corneal reflex, are absent. This indicates complete loss of brain function. Choice B, unequal reactive pupils, is incorrect as it suggests some level of brainstem function. Choice C, withdrawal from painful stimuli, is also incorrect as it is a spinal reflex and can occur even in the absence of brain function. Choice D, core temperature of 100.8� F, is irrelevant to assessing brain death.

Correct Answer: A

Rationale: The correct answer is A: Adherence to procedures by nursing staff. This should be evaluated first because medication errors are often caused by human factors such as staff not following proper procedures. By assessing adherence, the root cause of errors can be identified and addressed. Choice B: Clarity of interdisciplinary communication may contribute to errors but doesn't directly address staff adherence to procedures. Choice C: Number of new employees could be a factor, but focusing on adherence to procedures is more crucial. Choice D: Changes in administration procedures may impact errors, but evaluating staff adherence is more immediate and directly related to errors.
