Question

The nurse notes that the client's rhythm strip indicates a PR- interval of 0.28 seconds. What is the nurse's analysis of this problem?

Answer 1

Correct Answers:

1st degree AV block

Rationale :

💁‍♂️A PR interval of 0.28 seconds is prolonged beyond the normal 0.12–0.20 seconds, indicating a first-degree AV block.

📈This rhythm is regular and all impulses are conducted, just delayed, showing a prolonged PR interval without dropped beats.

🚫A Mobitz II block would present with dropped QRS complexes, which is not noted here.

🧠Atrial flutter and sinus bradycardia present with different rhythm characteristics unrelated to PR interval prolongation.

📌Core Message

A prolonged PR interval without missed beats indicates a first-degree AV block.

Answer 2

Correct Answers:

31

Rationale :

🧮Using the formula:

💁‍♂️Volume (mL) × Drop factor ÷ Time (min) = gtt/min

👉250 × 15 ÷ 120 = 31.25 → round to 31 gtt/min

💧This ensures accurate infusion of packed red blood cells over the prescribed 2 hours.

⚠️Accurate regulation helps prevent fluid overload or insufficient therapy.

📌Core Message

Use the standard gtt/min formula to accurately regulate IV blood transfusions.

Answer 3

Correct Answers:

Alert and oriented X 3

Rationale :

🧠Improvement in cognitive status reflects adequate cerebral perfusion and effective cardiac output.

💓A client alert and oriented in all spheres indicates stabilized or improved heart failure status.

📉Edema, tachycardia, or increased respiratory rate are signs of persistent or worsening heart failure.

🛌Mental clarity is a sensitive indicator of systemic and cerebral oxygenation status.

📌Core Message

Mental alertness signals improvement in chronic heart failure due to restored perfusion.

Answer 4

Correct Answers:

INR = 3.7 (normal ()8-1 1)

Rationale :

🩸An INR of 3.7 is significantly elevated above the normal 0.8–1.1 and indicates warfarin overdose, increasing bleeding risk.

🧪Fresh Frozen Plasma (FFP) provides clotting factors, making it the treatment of choice to correct coagulopathy.

📉Low hemoglobin or fibrinogen could result from bleeding, but FFP specifically addresses INR correction.

🩺The platelet count does not directly reflect the action or need for clotting factor replacement via FFP.

📌Core Message

An elevated INR from warfarin overdose requires FFP to restore coagulation balance.

Answer 5

Correct Answers:

"There are pacemaker wires in the right atrium and ventricle and will pace as needed."

Rationale :

⚡A DDD pacemaker paces both the atrium and ventricle and senses in both chambers to synchronize cardiac rhythm.

🔌It delivers a stimulus only when the natural heart rhythm is insufficient, offering dual chamber pacing.

🚫Wires are not placed in the left ventricle or both ventricles (which would be a biventricular pacer).

📏It does not fire with every beat, only as needed based on sensing activity.

📌Core Message

A DDD pacemaker provides dual chamber sensing and pacing in the atrium and ventricle.

Answer 6

Correct Answers:

Palpitations, shortness of breath

Rationale :

💓Atrial flutter causes a rapid atrial rate and often leads to palpitations, reduced cardiac output, and dyspnea.

💁‍♂️Clients feel shortness of breath due to inefficient ventricular filling and reduced perfusion.

🍽️Visual changes or polyuria are unrelated; they suggest endocrine or neurological disorders.

🩺Heart murmurs and anxiety may be present but are not hallmark signs of atrial flutter.

📌Core Message

Atrial flutter results in palpitations and dyspnea due to ineffective atrial contractions.

Answer 7

Correct Answers:

D-dimer fibrinogen and fibrin degradation products

Rationale :

🧪Diagnosing DIC requires evaluating clot formation and breakdown, which includes elevated D-dimer, reduced fibrinogen, and elevated fibrin degradation products (FDPs).

🧫These tests reflect coagulation cascade activation and exhaustion, hallmark signs of DIC.

🚫CBC or metabolic panels provide general information but not coagulation status.

🧬Eosinophils and lactic acid are unrelated to DIC’s clotting profile.

📌Core Message

DIC diagnosis requires testing for clotting activity and fibrin degradation like D-dimer, fibrinogen, and FDPs.

Answer 8

Correct Answers:

Cyanosis

Rationale :

🩸Cyanosis in DIC reflects microvascular thrombosis, leading to reduced perfusion and oxygenation in tissues.

🧠This sign is consistent with impaired blood flow due to widespread clot formation, a key feature of DIC.

📍Petechiae and bleeding reflect the hemorrhagic phase of DIC, not the clotting/perfusion phase.

🚫Epistaxis and hematuria are symptoms of bleeding, not decreased tissue perfusion.

📌Core Message

In DIC, cyanosis indicates poor tissue perfusion due to microvascular clotting.

Answer 9

Correct Answers:

"l will be ready to resume participation in the football league in two weeks"

Rationale :

⚠️Clients with implantable cardioverter-defibrillators (ICDs) must avoid contact sports to prevent device displacement or trauma.

🩺Returning to intense physical activity so soon is unsafe and indicates a lack of understanding.

📱Using a cellphone at a safe distance and microwave use are acceptable practices.

⚡Clients should understand that shocks from the ICD may feel like a kick to the chest, which is correctly stated.

📌Core Message

Contact sports are contraindicated after ICD placement due to device safety concerns.

Answer 10

Correct Answers:

Atrial and ventricular pacing

Rationale :

📈The ECG strip shows two pacing spikes before each QRS complex—one small spike preceding the P wave and another preceding the QRS complex.

⚡This is indicative of dual-chamber pacing, where the pacemaker is actively pacing both the atrium and the ventricle.

📟This type of pacing helps maintain synchronized atrioventricular contractions, optimizing cardiac output.

🚫Atrial-only pacing would display a single spike before the P wave, and biventricular pacing would look different and is used for resynchronization therapy in specific cases.

📌Core Message

ECG shows dual-chamber pacing with spikes before P and QRS, confirming atrial and ventricular pacing.
