質問 # 570
A critical care patient has recently survived a cardiac arrest and requires constant care. It is unclear if the patient is likely to survive to discharge and the patient's family wants to visit the patient. Which of the following actions by the nurse is LEAST correct when deciding on planning visitation?
正解：D
解説：
A patient's family may consist of individuals to whom they do not have any legal relationship and may consist of more than just their nuclear family. Who is included in the family unit is dependent on the patient's preferences. Collaboration with the interdisciplinary care team to determine visitation planning is appropriate. Visitation planning should ensure that the patient's privacy is maintained. Including the family's needs in formulating visitation planning is appropriate.
質問 # 571
The patient in renal failure is MOST LIKELY to suffer from which of the following hematological problems?
正解：D
解説：
The kidney is responsible for the production of erythropoietin, which acts on the bone marrow to increase production of RBCs. Iron, folic acid, and Vitamin B-12 are also needed for RBC production. A patient in renal failure is most likely to suffer from anemia because of the reduced production of the hormone erythropoietin.
The pluripotent stem cells in the bone marrow give rise to all white blood cells, including granulocytes and leukocytes. Polycythemia is a condition in which too many cells are produced in the bone marrow.
This is a response to low oxygen levels or malignancy (rare).
質問 # 572
The critical care nurse is caring for a patient on a mechanical ventilator for ongoing pulmonary problems. His Arterial Blood Gas (ABG) results are: pH 7.50; PaCO2 25 mm/Hg; PaO2 88 mm/Hg; and HCO3- 24 mEq/L. The ventilator is set in assist-control mode with a rate of 18 breaths/minute, tidal volume of 500 ml, and oxygen at 50%.
Based on the patient's ABG results, which intervention is CORRECT?
正解：A
解説：
The patient's ABG results indicate respiratory alkalosis, which is corrected by retaining more carbon dioxide (CO2). Changing the mode to intermittent mandatory ventilation, decreasing the rate, or decreasing the tidal volume may accomplish this.
The oxygen level is within normal limits, so do not adjust it. Adding PEEP would increase gas diffusion, not decrease CO2 levels.
質問 # 573
In patients with cardiac tamponade, there is an increase in Central Venous Pressure (CVP), Pulmonary Artery Diastolic pressure (PAD), and Pulmonary Artery Occlusion Pressure (PAOP), all within two to three mmHg of each other, referred to as diastolic plateau; this is accompanied by which three symptoms?
正解：B
解説：
The pericardial sac is normally stiff and noncompliant. Cardiac tamponade occurs when bleeding into the pericardial sac causes compression on the heart, compromising cardiac function and cardiac output, and can be a life-threatening condition if not treated promptly. Signs and symptoms of this condition include tachycardia, SOB, anxiety, decreased LOC, Pulsus Paradoxus (PP), increased CVP, PAD, and PAOP.
These values are often within two to three mmHg of one another, and this phenomenon is called diastolic plateau or equalization of pressures; it is accompanied by muffled heart tones, decreased BP and cardiac output.
質問 # 574
Why does a Subdural Hematoma (SDH) occur?
正解：D
解説：
Subdural Hematoma (SDH) refers to bleeding that occurs within the subdural space between the dura and arachnoid layer, creating direct pressure on the brain. SDH results from the rupture of the bridging veins between the brain and dura, bleeding from contused or lacerated brain tissue, or extension from an intracerebral hematoma. SDH can be acute, subacute, or chronic.
