AACN CCRN (Adult) - Direct Care Eligibility Pathway Sample Questions (Q463-Q468):

NEW QUESTION # 463
Which of the following is MOST likely to indicate a poor prognosis for a patient with Acute Kidney Injury (AKI)?

A. Prolonged diuretic phase
B. An intrarenal cause
C. Prolonged oliguric phase
D. A postrenal cause

Answer: C

Explanation:
A prolonged oliguric phase is an indicator of a poor prognosis for a patient with Acute Kidney Injury (AKI). A prolonged diuretic phase does not indicate a poor prognosis, like a prolonged oliguric phase would. A postrenal cause or intrarenal cause or AKI is not necessarily associated with a poor prognosis in those with AKI.

NEW QUESTION # 464
When blood bypasses the alveoli, gas exchange cannot occur and blood returns to the left side of the heart without being oxygenated. This is referred to as:

A. Overall hypoventilation
B. Dead space
C. Shunting
D. Diffusion defect

Answer: C

Explanation:
A shunt is when blood, going through an abnormal pathway, does not travel its normal route. This causes hypoxemia because gas exchange cannot take place and blood returns oxygenated. Physiologic shunts are caused by multiple conditions that result in closed, no ventilated alveoli, such as seen in ARDS (acute respiratory distress syndrome). Shunts caused anatomically include pulmonary arteriovenous fistulas (AVFs) or congenital cardiac anomalies of the heart and great vessels (such as Tetralogy of Fallout).
Dead space is characterized as the volume of a breath that does not participate in gas exchange; it is ventilation without perfusion.
Diffusion defect occurs when thickening of the alveolar-capillary membrane decreases oxygen diffusion and leads to hypoxemia.
Overall hypoventilation occurs when decreases in tidal volume (VT), respiratory rate, or both reduce minute ventilation and cause hypoventilation.

NEW QUESTION # 465
A patient is being admitted with an aortic aneurysm and has been scheduled for surgical repair. The nurse recognizes which of the following as a PRIMARY risk factor for developing an aortic aneurysm?

A. Hyperlipidemia
B. Alcoholism
C. Obesity
D. Smoking

Answer: D

Explanation:
Smoking is the strongest risk factor for developing aortic aneurysms. Obesity and alcoholism can contribute to a variety of health problems but they are not primary risk factors for aortic aneurysms.
Hyperlipidemia can increase the risk of the development of aortic aneurysms but not to the same degree that smoking can.

NEW QUESTION # 466
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?

A. Hypertension, muffled heart tones, and increased cardiac output
B. Muffled heart tones, decreased blood pressure, decreased cardiac output
C. Tachycardia, widening pulse pressure, and tachypnea
D. Tachycardia, restlessness, and muffled heart tones

Answer: B

Explanation:
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.

NEW QUESTION # 467
Of the following transfusion reactions, which is MOST LIKELY to manifest as acute onset hypoxemia and noncardiogenic pulmonary edema?

A. TRALI
B. Acute allergic reaction
C. Acute hemolytic reaction
D. TACO

Answer: A

Explanation:
A transfusion-related acute lung injury (TRALI) occurs due to an immune response to components of the transfusion and results in acute onset of hypoxemia and noncardiogenic pulmonary edema (generally within 6 hours).
A transfusion-associated circulatory overload (TACO) is caused by fluid volume overload. It is evidenced by dyspnea, tachypnea, crackles and cardiogenic pulmonary edema.
An acute hemolytic reaction produces fever, chills, dyspnea, tacypnea, hypotension, and chest/back pain as a result of immune destruction of transfused RBCs (due to blood incompatibility).
An acute allergic reaction is caused by preexisting antibodies. It results in urticaria, wheezing, and possible anaphylaxis.
