Key Concepts and Sample Questions

Let's delve into specific concepts and provide sample questions related to the Prophecy General ICU RN A v2 exam.

Cardiovascular System

Concept: Understanding Hemodynamics

Hemodynamics refers to the study of blood flow and the forces that influence it. Key hemodynamic parameters include:

• Heart Rate (HR): The number of times the heart beats per minute.
• Blood Pressure (BP): The force of blood against the artery walls. It's typically measured as systolic pressure (the pressure when the heart contracts) over diastolic pressure (the pressure when the heart relaxes).
• Cardiac Output (CO): The amount of blood pumped by the heart per minute. It's calculated as HR x Stroke Volume (SV).
• Stroke Volume (SV): The amount of blood ejected by the heart with each beat.
• Systemic Vascular Resistance (SVR): The resistance to blood flow in the systemic circulation.

Sample Question:

A patient in the ICU has the following hemodynamic parameters: HR 110 bpm, BP 90/60 mmHg, CO 4 L/min. Which of the following interventions is most appropriate?

(a) Administer a beta-blocker to decrease heart rate.

(b) Administer intravenous fluids to increase preload.

(c) Administer a diuretic to decrease preload.

(d) Administer an ACE inhibitor to decrease afterload.

Correct Answer: (b) Administer intravenous fluids to increase preload.

Explanation: The patient's low blood pressure and cardiac output suggest hypovolemia or inadequate preload. Administering intravenous fluids will help to increase preload, improve cardiac output, and raise blood pressure.

Respiratory System

Concept: Mechanical Ventilation

Mechanical ventilation is a life-support technique used to assist or replace spontaneous breathing. Key parameters to monitor include:

• Tidal Volume (VT): The volume of air delivered with each breath.
• Respiratory Rate (RR): The number of breaths per minute delivered by the ventilator.
• FiO2 (Fraction of Inspired Oxygen): The percentage of oxygen delivered with each breath.
• PEEP (Positive End-Expiratory Pressure): The pressure maintained in the airways at the end of exhalation to prevent alveolar collapse.

Sample Question:

A patient on mechanical ventilation has the following settings: VT 400 mL, RR 16 breaths/min, FiO2 50%, PEEP 5 cm H2O. The patient's arterial blood gas (ABG) results are: pH 7.30, PaCO2 55 mmHg, PaO2 85 mmHg, HCO3- 24 mEq/L. Which of the following ventilator adjustments is most appropriate?

(a) Increase the tidal volume to 500 mL.

(b) Decrease the respiratory rate to 12 breaths/min.

(c) Increase the FiO2 to 60%.

(d) Decrease the PEEP to 3 cm H2O.

Correct Answer: (a) Increase the tidal volume to 500 mL.

Explanation: The patient has respiratory acidosis (low pH and high PaCO2), indicating inadequate ventilation. Increasing the tidal volume will help to remove more carbon dioxide and improve the patient's pH.

Neurological System

Concept: Traumatic Brain Injury (TBI) Management

Traumatic Brain Injury (TBI) requires careful management to prevent secondary brain injury. Key interventions include:

• Monitoring Intracranial Pressure (ICP): Maintaining ICP within normal limits (5-15 mmHg).
• Maintaining Cerebral Perfusion Pressure (CPP): Ensuring adequate blood flow to the brain. CPP is calculated as Mean Arterial Pressure (MAP) - ICP.
• Managing Seizures: Administering anticonvulsants to prevent and treat seizures.
• Preventing Hypoxia and Hypotension: Maintaining adequate oxygenation and blood pressure.

Sample Question:

A patient with a severe TBI has an ICP of 22 mmHg and a MAP of 80 mmHg. What is the patient's cerebral perfusion pressure (CPP)?

(a) 58 mmHg

(b) 68 mmHg

(c) 92 mmHg

(d) 102 mmHg

Correct Answer: (a) 58 mmHg

Explanation: CPP is calculated as MAP - ICP. In this case, CPP = 80 mmHg - 22 mmHg = 58 mmHg. A CPP of 58 mmHg is below the target range for TBI patients (typically 60-70 mmHg), so interventions to increase CPP are needed.

Renal System

Concept: Acute Kidney Injury (AKI)

Acute Kidney Injury (AKI) is a sudden decline in kidney function. Key causes include:

• Prerenal AKI: Reduced blood flow to the kidneys (e.g., dehydration, heart failure).
• Intrarenal AKI: Damage to the kidney tissue (e.g., glomerulonephritis, acute tubular necrosis).
• Postrenal AKI: Obstruction of urine flow (e.g., kidney stones, enlarged prostate).

Sample Question:

A patient with AKI has the following laboratory results: BUN 60 mg/dL, Creatinine 3.5 mg/dL, Urine Output 20 mL/hour. The patient's fluid balance is +1500 mL over the past 24 hours. Which of the following interventions is most appropriate?

(a) Administer intravenous fluids to increase renal perfusion.

(b) Administer a diuretic to increase urine output.

(c) Restrict fluids to prevent further fluid overload.

(d) Prepare the patient for dialysis.

Correct Answer: (d) Prepare the patient for dialysis.

Explanation: The patient has significant AKI with fluid overload and oliguria (low urine output). Dialysis is likely needed to remove excess fluid and waste products.

Infection Control

Concept: Sepsis Management

Sepsis is a life-threatening condition caused by the body's overwhelming response to an infection. Key elements of sepsis management include:

• Early Recognition: Identifying signs and symptoms of sepsis, such as fever, tachycardia, tachypnea, and altered mental status.
• Blood Cultures: Obtaining blood cultures before administering antibiotics.
• Broad-Spectrum Antibiotics: Administering broad-spectrum antibiotics within one hour of sepsis recognition.
• Fluid Resuscitation: Administering intravenous fluids to improve tissue perfusion.
• Vasopressors: Administering vasopressors if fluid resuscitation is not sufficient to maintain blood pressure.

Sample Question:

A patient presents to the emergency department with suspected sepsis. Which of the following interventions should be initiated first?

(a) Administer vasopressors to increase blood pressure.

(b) Obtain blood cultures and administer broad-spectrum antibiotics.

(c) Administer intravenous fluids to improve tissue perfusion.

(d) Obtain a chest X-ray to rule out pneumonia.

Correct Answer: (b) Obtain blood cultures and administer broad-spectrum antibiotics.

Explanation: In sepsis management, obtaining blood cultures and administering broad-spectrum antibiotics within one hour is crucial to improve patient outcomes.
