1. Septic, anaphylactic, and neurogenic shock are all categorized as:
- A. Hypovolemic shock
- B. Cardiogenic shock
- C. Distributive shock
- D. Obstructive shock
Correct answer: C
Rationale: Septic, anaphylactic, and neurogenic shock are all types of distributive shock. Distributive shock is characterized by a decrease in systemic vascular resistance, leading to poor tissue perfusion. Septic shock is caused by severe infection, anaphylactic shock is an extreme allergic reaction, and neurogenic shock results from damage to the nervous system. Hypovolemic shock (Choice A) is characterized by a decrease in intravascular volume, cardiogenic shock (Choice B) is due to heart failure, and obstructive shock (Choice D) results from obstruction of blood flow. Therefore, the correct categorization for septic, anaphylactic, and neurogenic shock is distributive shock.
2. An 80-year-old patient is admitted with dyspnea, dependent edema, rales, and distended neck veins. As the nurse monitors the patient, he becomes increasingly short of breath and begins to have cardiac dysrhythmias. The most critical intervention for this patient is to:
- A. Ensure his airway is open and unobstructed.
- B. Apply oxygen to maintain his oxygen saturation above 94%.
- C. Administer Dobutamine to increase cardiac output.
- D. Start an IV for monitoring fluid intake.
Correct answer: A
Rationale: In a patient presenting with dyspnea, dependent edema, rales, distended neck veins, and developing cardiac dysrhythmias, the priority intervention is to ensure the airway is open and unobstructed. Maintaining an open airway is crucial for adequate ventilation and oxygenation, especially in a patient showing signs of impending respiratory distress and cardiac compromise. While applying oxygen to maintain oxygen saturation is important, ensuring airway patency takes precedence as it directly impacts the patient's ability to breathe. Administering Dobutamine may be necessary to improve cardiac output; however, addressing the airway first is essential to prevent further respiratory distress and worsening dysrhythmias. Starting an IV for monitoring fluid intake is not the most critical intervention in this scenario compared to ensuring airway patency and oxygenation.
3. Which of the following can cause coup-contrecoup injuries?
- A. Rotational forces
- B. Deformation forces
- C. Deceleration forces
- D. Acceleration forces
Correct answer: C
Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.
4. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is
- A. Surgical repair of a diseased coronary artery.
- B. Placement of an automatic internal cardiac defibrillator.
- C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow.
- D. Non-invasive radiographic examination of the heart.
Correct answer: C
Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that involves compressing plaque against the wall of a diseased coronary artery to improve blood flow. It is a minimally invasive procedure performed during a cardiac catheterization to open blockages in the coronary arteries. Surgical repair of a diseased coronary artery refers to procedures like coronary artery bypass grafting (CABG), not PTCA. Placement of an automatic internal cardiac defibrillator is a different intervention used for managing cardiac arrhythmias, not for improving coronary blood flow. A non-invasive radiographic examination of the heart would typically refer to procedures like a cardiac CT scan or an MRI, not PTCA.
5. The nursing care plan for a toddler diagnosed with Kawasaki Disease (mucocutaneous lymph node syndrome) should be based on the high risk for development of which problem?
- A. Chronic vessel plaque formation
- B. Pulmonary embolism
- C. Occlusions at the vessel bifurcations
- D. Coronary artery aneurysms
Correct answer: A
Rationale: The correct answer is chronic vessel plaque formation. Kawasaki Disease affects small and medium-sized blood vessels, leading to progressive inflammation and potential damage to the walls of medium-sized muscular arteries, which can result in coronary artery aneurysms. While other complications such as pulmonary embolism and occlusions at vessel bifurcations can occur in different conditions, for Kawasaki Disease, the primary concern is the development of chronic vessel plaque formation.
