Critical Care Nursing Questions and Answers PDF

Correct Answer: A

Rationale: The correct answer is A (Pain relief) because palliative care aims to provide comfort and improve the quality of life for individuals with serious illnesses. Pain relief is a crucial goal in palliative care to alleviate physical suffering. Nausea relief (B) is also commonly addressed in palliative care, but it is not a universal goal. Psychological support (C) is an important aspect of palliative care but is not always a primary goal. Withdrawal of life-support interventions (D) is not a goal of palliative care, as palliative care focuses on symptom management and improving quality of life, not hastening death.

Correct Answer: C

Rationale: The correct answer is C because obtaining certification in critical care nursing demonstrates the nurse's personal expertise in the specialty. Certification confirms the nurse's advanced knowledge and skills, enhancing professional credibility and potential for career advancement. This choice focuses on the individual nurse's competency and dedication to the specialty. Incorrect choices: A: Salary increase is not the primary benefit of certification, although it may be a potential outcome. B: Certification is often preferred but not always required to work in critical care. D: Employers may encourage certification, but it is not always mandated.

Correct Answer: B

Rationale: The correct answer is B: Hypoxemia and compensated respiratory acidosis. The patient's pH is within normal range (7.35), indicating compensation. The elevated PaCO2 (55 mm Hg) indicates respiratory acidosis due to inadequate ventilation, likely from COPD. The low PaO2 (65 mm Hg) indicates hypoxemia, common in pneumonia. The normal bicarbonate level (30 mEq/L) suggests metabolic compensation for respiratory acidosis. Choice A is incorrect as there is no metabolic alkalosis present. Choice C is incorrect as the patient has hypoxemia. Choice D is incorrect as the patient is showing compensated respiratory acidosis, not uncompensated.

Correct Answer: A

Rationale: The correct answer is A because palliative care indeed focuses on providing relief from pain and other symptoms, enhancing quality of life for patients with serious illnesses. This aligns with the essence of palliative care, which is to provide holistic support to improve comfort and well-being. The other choices are incorrect: B is wrong because palliative care does not aim to cure the underlying disease but rather to alleviate suffering; C is incorrect as palliative care can be initiated earlier in the disease trajectory, not just during the final days; and D is inaccurate because patients can continue receiving treatments alongside palliative care to manage symptoms and improve their quality of life.

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.
