AACN CCRN (Adult) - Direct Care Eligibility Pathway Sample Questions (Q467-Q472):

NEW QUESTION # 467
Which of the following findings is associated with cardiac tamponade?

A. Pulsus paradoxus
B. Increased cardiac output
C. Heightened awareness
D. Widened pulse pressure

Answer: A

Explanation:
Cardiac tamponade is compression on the heart that occurs when blood or fluid builds up in the space between the heart muscle and the outer covering sac of the heart. This compromises cardiac function and cardiac output. Signs and symptoms of this medical emergency include: tachycardia, SOB, anxiety and decreased level of consciousness, pulsus paradoxus (a fall of systolic blood pressure of >10 mmHg during the inspiratory phase), equalization of pulmonary pressures (increase in CVP, PAD, and PAOP all within 2 to 3 mmHg of each other) which is accompanied by muffled heart tones, decreased BP and cardiac output.

NEW QUESTION # 468
Which of the following ECG changes is expected in a patient with a potassium concentration of 3.0 mEq/L?

A. tall peaked T wave, prolonged PR interval, and prolonged QRS complex
B. inverted P wave, elevated T wave, and prolonged QT interval
C. ST segment depression, flattened and inverted T wave, and a U wave
D. shortened QT interval and complete atrioventricular block

Answer: C

Explanation:

Hypokalemia
A patient with a potassium concentration of 3.0 mEq/L has mild hypokalemia, which is a low level of potassium in the blood. Hypokalemia can cause various ECG changes that reflect the impairment of cardiac depolarization and repolarization. The most common ECG changes in mild hypokalemia are ST segment depression, flattened and inverted T wave, and a U wave, which is a positive deflection after the T wave.
These ECG changes can be seen in the examples from the web search results12. Other ECG changes that may occur in more severe hypokalemia are prolonged QT interval, frequent ectopic beats, and arrhythmias123. Tall peaked T wave, prolonged PR interval, and prolonged QRS complex are ECG changes associated with hyperkalemia, which is a high level of potassium in the blood12. Shortened QT interval and complete atrioventricular block are not typical ECG changes of hypokalemia, but may occur in other electrolyte disorders, such as hypercalcemia2. Inverted P wave, elevated T wave, and prolonged QT interval are not specific ECG changes of hypokalemia, but may occur in other cardiac conditions, such as ischemia, myocarditis, or pericarditis2.

NEW QUESTION # 469
All of the following are common signs/symptoms of Acute Renal Failure (ARF) EXCEPT:

A. bradycardia
B. oliguria
C. dry mucous membranes
D. nausea and vomiting

Answer: A

Explanation:
Signs and symptoms of acute renal failure include:
* Oliguria < 400 mL/d or anuria < 100 mL/d
* Tachycardia
* Hypotension (prerenal)
* Hypertension (intrarenal)
* Flat neck veins (prerenal)
* Distended neck veins (intrarenal)
* Dry mucous membranes
* Cool, clammy skin
* Lethargy
* Deep, rapid respirations
* Vomiting
* Nausea
* Confusion

NEW QUESTION # 470
Which of the following accurately describes the key components of Cushing's Triad?

A. Tachycardia, hypotension, and shallow respirations
B. Narrowing pulse pressure, hyperthermia, and bradypnea
C. Bradycardia, widening pulse pressure, and abnormal respirations
D. Tachycardia, hypertension, and Kussmaul respirations

Answer: C

Explanation:
Cushing's Triad is a clinical syndrome characterized by widening pulse pressure, bradycardia, and abnormal respirations - indicative of increased ICP (Increased Intracranial Pressure). Tachycardia and hypotension generally indicate shock, not increased ICP. Narrowing pulse pressure and hyperthermia can occur in various conditions, but they do not form a part of the Cushing's Triad and are not generally connected. Tachycardia, hypertension, and Kussmaul respirations are often associated with metabolic acidosis, not increased ICP.

NEW QUESTION # 471
A 36-year-old female patient is brought to the ICU following a severe anaphylactic reaction to a bee sting. Despite administering epinephrine, antihistamines, and steroids administered in the ER, her blood pressure remains low and she is experiencing wheezing and shortness of breath. What is the BEST next step in her management?

A. Intubate and mechanically ventilate
B. Administer a second dose of epinephrine
C. Start a bronchodilator
D. Begin vasopressor therapy

Answer: A

Explanation:
With persistent low blood pressure and respiratory distress despite medication, the patient is in anaphylactic shock. Intubation and mechanical ventilation will be necessary to ensure patency of the patient's airway and should be the next step, as the airway is the most important aspect of managing this patient. A second dose of epinephrine may be necessary but does not adequately address the patient's airway compromise. Vasopressors are used when hypotension persists despite fluid resuscitation and epinephrine, but the immediate concern here is the patient's respiratory status. A bronchodilator may help relieve wheezing, but if the patient has been resistant to initial medical treatments, intubation is the next intervention that should be implemented to protect the patient's airway.
