Question

The nurse is assessing a client with suspected metabolic acidosis. Which finding would be consistent with this diagnosis?

Answer 1

Correct Answers:

Kussmaul respirations

Rationale :

👃Kussmaul respirations are deep, rapid breaths that represent the body’s attempt to compensate for metabolic acidosis by reducing carbon dioxide.

🧠This respiratory pattern helps correct the low pH by blowing off acid (CO₂), seen in conditions like diabetic ketoacidosis.

🚫Muscle spasms and paresthesia are more commonly associated with alkalosis, not acidosis.

👂Tinnitus is usually linked to salicylate toxicity or ototoxicity, not metabolic acidosis specifically.

📌Core Message

Kussmaul respirations are a classic compensatory sign of metabolic acidosis.

Answer 2

Correct Answers:

Check groin dressing

Rationale :

🩹Following a percutaneous valvuloplasty, bleeding at the insertion site is a priority concern, especially within the first hour post-procedure.

🩸The left groin is where the catheter was introduced, and bleeding or hematoma formation can lead to serious complications like hemorrhage or pseudoaneurysm.

🧾Hematology labs and pain assessment are important, but do not supersede the immediate need to monitor for bleeding.

📉Glucose is not an immediate priority unless the patient is unstable or diabetic.

📌Core Message

After valvuloplasty, always assess the groin site first to detect bleeding complications.

Answer 3

Correct Answers:

Use a soft bristle toothbrush
Check for black, tarry stools
Keep appointments for PT/INR monitoring

Rationale :

🩸Using a soft toothbrush minimizes gum bleeding, which is a concern with warfarin, an anticoagulant.

🩸Black, tarry stools may indicate GI bleeding, a serious adverse effect of warfarin therapy.

📅PT/INR monitoring is essential to ensure therapeutic anticoagulation without increasing bleeding risk.

🧫Infection risk does not increase directly due to warfarin, and aspirin—even in small doses—can increase bleeding and should generally be avoided or used under close medical supervision.

📌Core Message

After mechanical valve placement, teach about bleeding precautions and regular INR checks with warfarin.

Answer 4

Correct Answers:

BNP 700pg/ml (<100pg/m1)

Rationale :

📈BNP (B-type natriuretic peptide) is a direct marker of ventricular stretch and fluid overload, and a value of 700 pg/mL is significantly elevated, indicating acute heart failure exacerbation.

🧪This lab finding explains the client's dyspnea and signals worsening cardiac function, requiring immediate provider notification.

🖼️Cardiomegaly on x-ray confirms chronic changes, but BNP is more urgent and modifiable in the acute setting.

📊The other values (hematocrit, ejection fraction) are either normal or not emergent.

📌Core Message

BNP elevation indicates acute heart failure worsening and requires urgent reporting.

Answer 5

Correct Answers:

Assess level of consciousness

Rationale :

🧠Respiratory acidosis causes CO₂ retention, leading to cerebral vasodilation and altered mental status; hence monitoring LOC is critical.

🛑Clients with COPD are at high risk for CO₂ narcosis, so subtle changes in alertness may signal worsening respiratory failure.

🧪Monitoring sodium or administering diuretics does not directly address the neurologic effects of acidosis.

💧Skin turgor assesses hydration but isn't specific to respiratory acidosis management.

📌Core Message

In respiratory acidosis, assess mental status to detect CO₂-induced LOC changes.

Answer 6

Correct Answers:

Endocarditis

Rationale :

🦠Tissue valves are more biologically active, and although they require less anticoagulation, they are more prone to bacterial colonization, leading to endocarditis.

🧬The immune system may recognize tissue valves as foreign, making infection more likely.

🩸Hemolytic anemia and PT/INR elevation are more associated with mechanical valves, and hypertension is unrelated to valve type.

📌Core Message

Endocarditis is a more frequent complication with tissue valve replacements due to infection risk.

Answer 7

Correct Answers:

Mitral valve prolapse

Rationale :

😫Mitral valve prolapse commonly presents with atypical chest pain and dyspnea, often unrelated to activity, and sometimes with anxiety or palpitations.

💓The valve may bulge backward into the atrium, causing mitral regurgitation and symptoms that are position- or stress-related.

🧠Unlike stenotic lesions (e.g., mitral/aortic stenosis), symptoms aren't typically exertional.

🚫Aortic regurgitation and stenosis usually produce exertional symptoms and fatigue instead.

📌Core Message

Mitral valve prolapse can cause non-exertional dyspnea and chest pain, often with vague or atypical symptoms.

Answer 8

Correct Answers:

Check pulse oximetry

Rationale :

❗In a patient with heart failure and pulmonary congestion, oxygenation is the first priority to assess for immediate respiratory compromise.

📉Pulse oximetry quickly evaluates if the client requires supplemental oxygen or more intensive respiratory support.

💊Giving digoxin or ECG are important but not time-sensitive compared to checking oxygen saturation first.

💨Without assessing oxygen levels, treatment might be delayed, leading to hypoxia.

📌Core Message

In heart failure with dyspnea, pulse oximetry is the first intervention to assess oxygenation status.

Answer 9

Correct Answers:

Auscultate heart sounds

Rationale :

🩺In pericarditis, one major complication is cardiac tamponade, which can be detected early by muffled or distant heart sounds.

⚠️These sounds indicate fluid buildup in the pericardial sac, compressing the heart and reducing cardiac output.

🧬Vital signs may later show hypotension and JVD, but heart sounds change first.

🚫WBC count, glucose, and BP alone won’t confirm tamponade.

📌Core Message

Auscultating heart sounds helps detect cardiac tamponade, a serious complication of pericarditis.

Answer 10

Correct Answers:

Uncompensated respiratory acidosis

Rationale :

🧪The ABG shows pH 7.33 (low), PaCO₂ 49 mmHg (elevated), and HCO₃ 26 (normal), which means the acidosis is due to respiratory causes and is uncompensated because the bicarb is not yet elevated.

💨CO₂ retention is the driving factor, typically caused by hypoventilation or lung disease (e.g., COPD).

📉The kidneys have not yet compensated, so this is an acute problem.

🚫Metabolic acidosis would show low HCO₃, and alkalosis would show high pH.

📌Core Message

Uncompensated respiratory acidosis is identified by low pH, elevated PaCO₂, and normal HCO₃.
