Correct Answer: C

Rationale: The correct answer is C: dialysis disequilibrium syndrome. This occurs when there is a rapid decrease in urea concentration in the blood during hemodialysis, causing fluid shifts and cerebral edema leading to symptoms like headache, nausea, and confusion. Dialyzer membrane incompatibility (A) would present with allergic reactions, not neurological symptoms. A shift in potassium levels (B) may cause muscle weakness or cardiac arrhythmias, but not the described symptoms. Hypothermia (D) would present with low body temperature and shivering, not the neurological symptoms mentioned.

Correct Answer: A

Rationale: Step 1: Bringing in the patient's i-Pod with favorite music can provide personalized, soothing sounds, reducing stress and anxiety for the patient. Step 2: Familiar music can create a calming environment, distracting the patient from external noise. Step 3: Listening to music may improve patient comfort and overall experience in the critical care unit. Summary: Option A is correct as it directly addresses noise reduction by providing a personalized, calming environment for the patient. Options B, C, and D do not specifically target noise reduction but focus on other aspects of care or facility improvement.

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: B

Rationale: The correct answer is B because sitting at the bedside and asking if there is anything the patient needs demonstrates empathy and support. It allows the patient to express their concerns and fears, providing emotional comfort. It shows the nurse is actively listening and willing to help address any immediate needs or concerns. Choice A is incorrect because it dismisses the patient's feelings and may come across as invalidating. Choice C is incorrect because insisting that family members remain may not be what the patient needs at that moment and could cause additional stress. Choice D is incorrect because it does not address the patient's emotional distress and may not be true in the context of terminal illness.

Correct Answer: C

Rationale: The correct answer is C: Hospitality programs. Given the family's long journey and the stressful situation of having a child diagnosed with leukemia, their immediate need would likely be for accommodations and support services provided by hospitality programs, such as lodging, meals, transportation assistance, and emotional support. This would help alleviate the burden of their travel and allow them to focus on being with their daughter in the ICU. Incorrect answers: A: Educational materials - While education is crucial for families, it may not be the most immediate need in this situation. B: Weekly group family information sessions - These sessions may be helpful for support and information-sharing, but they are not as urgent as addressing the family's immediate needs. D: Pet therapy - While pet therapy can provide emotional support, it may not be the most pressing need for this family at the moment.
