Question

A nurse is caring for a client on mechanical ventilation and finds the client agitated and thrashing about. What action by the nurse is most appropriate?

Answer 1

Correct Answers:

Assess the cause of the agitation.

Rationale :

🟩 Agitation in a mechanically ventilated client is often a symptom of an underlying problem, such as hypoxia, pain, anxiety, or tube displacement.

🟩 Immediate assessment helps determine whether life-threatening complications, such as hypoventilation or accidental extubation, are present.

🟩 Prioritizing assessment follows the nursing process and avoids masking the true cause with sedation or restraints.

🟩 Unaddressed causes of agitation can compromise oxygenation or increase ventilator asynchrony.

🟩 Once the cause is identified, targeted interventions can safely calm the patient.

Answer 2

Correct Answers:

Fully compensated Respiratory Acidosis

Rationale :

🟧 A pH of 7.37 is within normal range, indicating that the body has compensated for a primary imbalance.

🟧 The elevated PaCO₂ (54) and elevated HCO₃ (31) reflect a chronic respiratory acidosis that has been compensated by renal retention of bicarbonate.

🟧 This pattern is commonly seen in clients with chronic respiratory conditions like COPD.

🟧 Full compensation means the pH is normal but the PaCO₂ and HCO₃ remain abnormal in opposite directions.

🟧 Accurate interpretation of ABG requires analyzing all components in context.

Answer 3

Correct Answers:

Call respiratory therapy to obtain the pressure within the balloon

Rationale :

🟦 The ETT cuff pressure must be carefully monitored to avoid complications like tracheal damage or aspiration.

🟦 Respiratory therapy has the equipment and training to measure cuff pressures, typically keeping it between 20–30 cm H₂O.

🟦 Blindly inflating or deflating the balloon can lead to overinflation (tracheal necrosis) or underinflation (air leak/aspiration).

🟦 Collaboration with the respiratory team ensures safe airway management and patient comfort.

🟦 If unsure about tube position or balloon status, cuff pressure measurement is the priority intervention.

Answer 4

Correct Answers:

Pancreatitis

Rationale :

🟥 Pancreatitis is an indirect cause of ARDS, triggered by systemic inflammatory mediators that affect the lungs secondarily.

🟥 Unlike direct causes (e.g., aspiration, near-drowning), pancreatitis leads to ARDS via widespread capillary leakage and immune activation.

🟥 Cytokine release from inflamed pancreatic tissue increases lung capillary permeability, causing pulmonary edema.

🟥 Recognizing indirect versus direct causes is essential for accurate diagnosis and timely interventions.

🟥 ARDS can occur in the absence of direct lung injury due to inflammatory processes elsewhere in the body.

Answer 5

Correct Answers:

Hypertension

Rationale :

🟨 Hypertension typically leads to low-output heart failure, not high-output.

🟨 In hypertension, increased afterload places strain on the heart, eventually leading to ventricular dysfunction.

🟨 High-output heart failure occurs when the heart pumps adequately but is unable to meet abnormally elevated metabolic demands, such as in anemia or sepsis.

🟨 Understanding the pathophysiology of different heart failure types guides appropriate therapy.

🟨 Hypertension is a chronic load problem, not a demand-driven failure like sepsis or hyperthyroidism.

Answer 6

Correct Answers:

Decreased afterload

Rationale :

🟩 ACE inhibitors reduce the conversion of angiotensin I to angiotensin II, resulting in vasodilation and reduced afterload.

🟩 This effect decreases the resistance the left ventricle must pump against, making it easier for the failing heart to eject blood.

🟩 Lower afterload improves cardiac output and symptom control in heart failure.

🟩 These drugs also reduce aldosterone-mediated fluid retention, indirectly helping with preload.

🟩 ACE inhibitors are foundational in long-term heart failure management.

Answer 7

Correct Answers:

Perform a stat pericardiocentesis

Rationale :

🟥 Cardiac tamponade is a medical emergency where fluid compresses the heart, restricting ventricular filling and cardiac output.

🟥 The hallmark signs—hypotension, muffled heart sounds, and JVD—make up Beck’s triad, strongly suggestive of tamponade.

🟥 Pericardiocentesis relieves the pressure by draining fluid, restoring hemodynamic stability.

🟥 Delayed intervention can lead to cardiac arrest or pulseless electrical activity.

🟥 This procedure should be performed immediately and under sterile conditions, often guided by ultrasound.

Answer 8

Correct Answers:

Pulmonary crackles/rales

Rationale :

🟦 Left-sided heart failure causes backup of blood into the pulmonary circulation, leading to increased hydrostatic pressure in pulmonary capillaries.

🟦 This results in pulmonary edema, which manifests as crackles or rales heard during auscultation.

🟦 Other symptoms include dyspnea, orthopnea, and paroxysmal nocturnal dyspnea (PND).

🟦 Pulmonary congestion is a defining feature of left-sided heart failure, distinguishing it from right-sided failure.

🟦 Monitoring breath sounds provides essential clues to fluid volume status and treatment response.

Answer 9

Correct Answers:

ST segment elevation

Rationale :

🟨 ST elevation on an ECG indicates active myocardial injury, typically seen in acute STEMI.

🟨 This results from transmural ischemia, where a full-thickness portion of the myocardium is deprived of oxygen.

🟨 Early identification allows for urgent reperfusion therapy such as PCI or thrombolytics.

🟨 Recognizing ST elevation patterns is critical in emergency cardiac care.

🟨 The longer the myocardium remains ischemic, the greater the risk of irreversible damage.

Answer 10

Correct Answers:

"A CABG is not a cure-It may improve your quality of life"

Rationale :

🟩 Coronary artery bypass grafting (CABG) improves blood flow, but it does not eliminate atherosclerosis or underlying risk factors.

🟩 Patients must continue with lifestyle changes, medications, and regular follow-up to manage coronary artery disease (CAD).

🟩 Effective education includes clarifying that surgery is part of a long-term treatment plan, not a permanent solution.

🟩 Misconceptions can lead to nonadherence and recurrence of symptoms.

🟩 Nurses play a key role in reinforcing realistic expectations and self-care behaviors.
