Critical Care Nursing NCLEX Questions

Correct Answer: A

Rationale: Step 1: Symptoms of weight loss, racing heart rate, and difficulty sleeping are common in hyperthyroidism. Step 2: Presence of moist skin, fine hair, prominent eyes, lid retraction, and staring expression are classic signs of Grave's disease, a type of hyperthyroidism. Step 3: Grave's disease is an autoimmune disorder where the thyroid gland is overactive, leading to excessive production of thyroid hormones. Step 4: Excess thyroid hormones increase metabolic rate, causing weight loss, racing heart rate, and insomnia. Step 5: Therefore, the findings described in the question are consistent with Grave's disease.

Correct Answer: A

Rationale: The correct answer is A: Thirty-degree elevation of the head of the bed. This is the priority nursing intervention for a mechanically ventilated patient following bilateral lung transplantation because it helps optimize ventilation-perfusion matching, reduces the risk of aspiration, and improves oxygenation. Elevating the head of the bed also decreases the risk of ventilator-associated pneumonia. B: Endotracheal suctioning as needed is important but not the priority intervention in this case. C: Frequent side to side repositioning is important for preventing pressure ulcers but is not the priority for a ventilated patient post-lung transplant. D: Sequential compression stockings are used for preventing deep vein thrombosis, which is important but not the priority in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Administer oxygen as prescribed. Dyspnea in a hospice patient often indicates respiratory distress, and administering oxygen can help improve oxygenation and alleviate breathing difficulty. Positioning the patient flat on their back (A) may worsen dyspnea due to increased pressure on the diaphragm. Restricting fluid intake (C) is not appropriate as dehydration can exacerbate respiratory distress. Chest physiotherapy (D) may not be suitable for a hospice patient experiencing dyspnea as it can be physically taxing and may not address the underlying cause effectively.

Correct Answer: B

Rationale: The correct answer is B: Manage the patient's pain and symptoms. In palliative care, the primary goal is to provide comfort and improve quality of life for terminally ill patients. Managing pain and symptoms is crucial in achieving this goal. By addressing pain and symptoms, the nurse can help enhance the patient's comfort and well-being. Other choices are incorrect because palliative care focuses on improving quality of life rather than curing the underlying disease (A), prolonging life expectancy (C), or primarily addressing family concerns (D). Prioritizing pain and symptom management aligns with the holistic approach of palliative care.

Correct Answer: B

Rationale: The elevated BUN and creatinine levels with a normal BUN/creatinine ratio indicate impaired kidney function. This pattern is commonly seen in acute kidney injury, such as acute tubular necrosis (ATN). In ATN, there is damage to the renal tubules leading to decreased excretion of waste products, resulting in elevated BUN and creatinine levels. The normal BUN/creatinine ratio suggests that the impairment is due to renal tubular dysfunction rather than prerenal causes like hypovolemia or postrenal causes like urinary obstruction. Increased nitrogen intake would not produce this specific pattern of results. Fluid resuscitation would likely result in dilution of BUN and creatinine levels, leading to lower values.
