This emphasizes the holistic approach required in critical care settings. Lastly, multisystem complications such as sepsis and shock states are included to assess the ability to manage life-threatening conditions that affect multiple organ systems.
Topic 3
  • CLINICAL JUDGMENT: This section measures the skills of Critical Care Nurses and covers a wide range of medical conditions across various systems. It includes cardiovascular issues such as acute coronary syndrome, heart failure, and cardiomyopathies, demonstrating the need for in-depth knowledge in managing these critical conditions. The section also addresses respiratory emergencies like pulmonary embolism and ARDS, emphasizing the importance of understanding respiratory failure and chronic conditions.
Topic 6
  • Facilitation of learning is emphasized, indicating the role of nurses in educating patients and families about health management. Collaboration is another key component, focusing on teamwork within healthcare settings to improve patient outcomes. Systems thinking is included to encourage understanding of how different components of healthcare interact. Finally, clinical inquiry is highlighted as a means to foster evidence-based practice and continuous improvement in patient care.

AACN CCRN (Adult) - Direct Care Eligibility Pathway Sample Questions (Q250-Q255):

NEW QUESTION # 250
Which of the following is a goal of intra-aortic balloon pump therapy?

  • A. Maximize aortic diastolic augmentation pressure
  • B. Decrease MAP
  • C. Increase end-diastolic blood pressure
  • D. Increase systolic blood pressure

Answer: A

Explanation:
The IABP (Intra-Aortic Balloon Pump) provides cardiac assistance by improving myocardial oxygen supply and reducing cardiac workload. The IAPB works on the principle of counterpulsation. Gas (helium or CO2) moves back and forth from the IABP console to the IABP catheter, causing the balloon to inflate (during ventricular diastole, increasing intra-aortic pressure and blood flow to the coronary arteries) and deflate (just prior to ventricular systole, decreasing intra-aortic pressure). This counterpulsation increases the Mean Arterial Pressure (MAP), improves coronary artery blood flow and perfusion during diastole, and decreases systolic blood pressure and end-diastolic blood pressure.


NEW QUESTION # 251
All of the following clinical situations may affect the accuracy of POC blood glucose measurements EXCEPT:

  • A. high blood triglycerides
  • B. ibuprofen use
  • C. a patient in hypovolemic shock
  • D. blood glucose levels that exceed 500 mg/dL

Answer: B

Explanation:
Several clinical conditions may influence POC glucose measurements. Shock or hypotensive states can lead to inadequate tissue perfusion in fingers, thus increasing inaccuracies of fingerstick glucometer analysis. Naturally occurring blood substances, such as hematocrit and high triglycerides, can also interfere with glucose measurement accuracy and are associated with higher glucose levels.
Acetaminophen use, not ibuprofen, can cause falsely low readings. Blood glucose levels that exceed 500 mg/dL may result in a variable error.


NEW QUESTION # 252
Which of the following medications does NOT need to be discontinued by a patient who has recently been diagnosed with pulmonary fibrosis?

  • A. Amiodarone
  • B. Prednisone
  • C. Bleomycin
  • D. Nitrofurantoin

Answer: B

Explanation:
Medications that can cause lung toxicity should be discontinued and avoided by patients who have pulmonary fibrosis due to the risk that they will increase the development of scar tissue within the lungs. These medications include nitrofurantoin, amiodarone, and bleomycin. Prednisone is a corticosteroid and is used to treat pulmonary fibrosis.


NEW QUESTION # 253
Of the following, which hemodynamic profile MOST accurately reflects a patient in hypovolemic shock?

  • A. CI 2.3 L/min/m2, pulmonary arterial pressure 17 mm Hg, sinus tachycardia, warm skin
  • B. CI 2.1 L/min/m2, pulmonary arterial pressure 10 mm Hg, NSR, warm skin
  • C. CI 2.2 L/min/m2, pulmonary arterial pressure 15 mm Hg, sinus tachycardia, cool/clammy skin
  • D. CI 2 L/min/m2, pulmonary arterial pressure 7 mm Hg, sinus tachycardia, cool/clammy skin

Answer: D

Explanation:
Hypovolemic shock occurs when there is inadequate volume in the vascular space. This volume depletion may be caused by blood loss (either internal or external), or by the vascular fluid volume shifting out of the vascular space into other body fluid spaces. This loss of volume results in insufficient circulating blood to maintain tissue perfusion.
A normal cardiac Index (CI) lies between 2.5-4.3 L/min/m2. Therefore, a CI of 2 L/min/m2 indicates hypovolemic shock.
A pulmonary arterial pressure (PAP) is typically 8-20 mm Hg. Therefore, a low PAP of 7 mm Hg indicates hypovolemic shock.
Sinus tachycardia and cool/clammy skin are also indications of hypovolemic shock.


NEW QUESTION # 254
The nurse is assisting during a routine cardiac catheterization and notes that the patient's extremity feels cool to the touch. Furthermore, the nurse notes that the extremity is losing color and upon auscultation, notes a thready, weak pulse in the same extremity.
Which of the following conditions has the patient MOST likely developed?

  • A. Pulmonary embolism
  • B. Coronary artery dissection
  • C. Cerebrovascular accident due to embolus
  • D. Thromboembolism

Answer: D

Explanation:
During cardiac catheterization, a number of complications may occur, including peripheral thromboembolism (or embolus in an extremity). In this scenario, manifestations include pain, pallor, weak pulse or pulselessness (in extreme cases), paresthesias, and paralysis; the extremity may also be cool to touch.
Interventions for this condition include continuing unfractionated heparin or other anticoagulant, in addition to possible thrombolytic therapy directly to the clot using a tracking catheter. If these fail, surgical intervention may be necessary.
A stroke, also known as a cerebrovascular accident (CVA), can be caused by a thromboembolism but presents with neurological symptoms. You would need to monitor the patient for signs and symptoms of neurologic compromise including speech patterns, orientation, and vision.
Coronary artery dissection will have a systemic effect, not a local effect.
In pulmonary embolism, you would note breathing irregularities and a drop in arterial oxygen saturation. You would need to provide immediate supplemental oxygen and administer heparin and other thrombolytic therapy as necessary.
