Question

The nurse identified the problem of "decreased cardiac output" for the client diagnosed with a pulmonary embolism, Which intervention should be included in the plan of care?

Answer 1

Correct Answers:

Assess skin color, pulse, and temperature

Rationale :

🎯 A pulmonary embolism (PE) obstructs pulmonary blood flow and can reduce blood returning to the left side of the heart, resulting in decreased cardiac output.

🎯 Assessing skin color, peripheral pulses, and skin temperature provides important information about the adequacy of systemic tissue perfusion.

🎯 Decreased cardiac output can cause pallor or cyanosis, cool extremities, and weak peripheral pulses because less oxygenated blood reaches peripheral tissues.

🎯 The nurse should monitor peripheral pulses for changes in strength, rate, and quality that may indicate worsening hemodynamic status.

🎯 Cool or clammy skin can indicate peripheral vasoconstriction as the body attempts to preserve circulation to vital organs.

🎯 Additional manifestations of reduced cardiac output can include hypotension, tachycardia, decreased urine output, altered mental status, and delayed capillary refill.

🎯 Repeated assessment of these findings helps determine whether the client's circulatory status is improving or deteriorating.

🎯 Therefore, assessing skin color, pulse, and temperature directly addresses the identified problem of decreased cardiac output.

Answer 2

Correct Answers:

The client demonstrates pursed-lip breathing correctly

Rationale :

🧿 Pursed-lip breathing is an appropriate strategy for a client with COPD who has ineffective gas exchange.

🧿 The technique involves inhaling slowly through the nose and exhaling slowly through pursed lips.

🧿 Pursed-lip breathing creates slight positive pressure during expiration, helping prevent premature collapse of small airways.

🧿 Keeping the airways open longer promotes more complete exhalation of trapped air and improves ventilation.

🧿 Improved ventilation can enhance gas exchange by facilitating oxygen entry and carbon dioxide elimination.

🧿 The technique can also decrease air trapping, dyspnea, and the work of breathing in clients with COPD.

🧿 Demonstrating the technique correctly is an observable and measurable outcome that directly relates to improving respiratory function.

🧿 Therefore, correctly demonstrating pursed-lip breathing is the most appropriate outcome for the problem of ineffective gas exchange.

Answer 3

Correct Answers:

Warfarin (Coumadin)

Rationale :

🍊 Warfarin (Coumadin) is an anticoagulant used to reduce the risk of thrombus formation and systemic embolization in appropriate clients with atrial fibrillation (AF).

🍊 During atrial fibrillation, the atria contract rapidly and ineffectively, resulting in incomplete emptying and blood stasis, particularly in the left atrial appendage.

🍊 Blood stasis increases the risk of atrial thrombus formation, which can subsequently embolize into the systemic circulation.

🍊 A thrombus originating in the left atrium can travel to the cerebral circulation and cause an ischemic stroke.

🍊 Warfarin reduces clot formation by interfering with the synthesis of vitamin K-dependent clotting factors II, VII, IX, and X.

🍊 Clients receiving warfarin require monitoring of prothrombin time (PT) and INR to ensure therapeutic anticoagulation while minimizing bleeding risk.

🍊 The nurse should monitor for manifestations of bleeding, including bruising, hematuria, melena, bleeding gums, and prolonged bleeding.

🍊 Therefore, warfarin is the medication among these choices that directly helps prevent the thromboembolic complication associated with atrial fibrillation.

Answer 4

Correct Answers:

Collect a sputum specimen for culture

Rationale :

🌸 A client with community-acquired pneumonia and fever, chills, and shortness of breath requires prompt identification and treatment of the causative organism.

🌸 A sputum specimen for culture and sensitivity helps identify the specific microorganism responsible for the respiratory infection.

🌸 The specimen should ideally be collected before the first dose of antibiotic therapy because antibiotics can decrease the number of organisms present.

🌸 Obtaining the culture first increases the likelihood of obtaining an accurate microbiologic result.

🌸 Culture and sensitivity results can help the provider determine which antibiotic is most effective against the identified pathogen.

🌸 Antibiotic therapy should be started promptly after appropriate cultures are obtained and should not be unnecessarily delayed.

🌸 The client's temperature of 102.6°F (39.2°C) and chills support the presence of a significant infectious process requiring antimicrobial treatment.

🌸 Therefore, among the listed interventions, collecting the sputum specimen before antibiotic administration is the highest priority.

Answer 5

Correct Answers:

"Cardioversion is the timing of the delivery of the electrical current on the heart."

Rationale :

🌻 Cardioversion delivers an electrical shock that is synchronized with the heart’s electrical activity, specifically the R wave.

🌻 Synchronization ensures that the electrical current is delivered at a carefully selected point in the cardiac cycle.

🌻 This timing prevents the shock from occurring during the vulnerable T wave, which represents ventricular repolarization.

🌻 Delivering a shock during the T wave can precipitate a dangerous ventricular dysrhythmia such as ventricular fibrillation.

🌻 Synchronized cardioversion is commonly used for unstable tachydysrhythmias when the client has a pulse, such as atrial fibrillation, atrial flutter, and certain supraventricular tachycardias.

🌻 Defibrillation, in contrast, delivers an unsynchronized shock without coordinating the shock with the cardiac cycle.

🌻 Defibrillation is used for ventricular fibrillation and pulseless ventricular tachycardia, which are cardiac arrest rhythms.

🌻 Therefore, the key distinction is that cardioversion involves timing or synchronization of electrical energy with cardiac electrical activity.

Answer 6

Correct Answers:

High oxygen concentrations may eliminate the hypoxic stimulus to breathe

Rationale :

🌼 Clients with COPD, particularly those with chronic hypercapnia, should receive carefully titrated oxygen therapy.

🌼 Traditionally, these clients are described as potentially relying partly on hypoxemia as a respiratory stimulus when chronic CO₂ retention reduces responsiveness to elevated PaCO₂.

🌼 Giving excessively high concentrations of oxygen can contribute to worsening hypercapnia in susceptible clients.

🌼 Clinically, this worsening CO₂ retention is explained more completely by mechanisms including ventilation-perfusion mismatch, the Haldane effect, and a reduction in hypoxic ventilatory drive.

🌼 Excessive oxygen can therefore result in increasing PaCO₂ and potentially worsening respiratory acidosis.

🌼 Oxygen should never be withheld from a hypoxemic client simply because the client has COPD.

🌼 Oxygen is instead administered at a controlled concentration and adjusted according to oxygen saturation, ABGs, and the prescribed target; in clients at risk for hypercapnic respiratory failure, a target SpO₂ of about 88%–92% is commonly used.

🌼 Therefore, among the provided choices, the best answer is that high oxygen concentrations may reduce the client's hypoxic respiratory stimulus.

Answer 7

Correct Answers:

Tension Pneumothorax

Rationale :

🏵️ A tension pneumothorax occurs when air enters the pleural space and becomes trapped, causing progressively increasing intrathoracic pressure.

🏵️ The client's recent left-sided chest trauma and rib fractures create a significant risk for injury to the lung and development of a pneumothorax.

🏵️ The increasing dyspnea indicates worsening impairment of ventilation as the affected lung becomes compressed.

🏵️ An oxygen saturation of 86% indicates significant hypoxemia and requires immediate intervention.

🏵️ Tracheal deviation away from the affected side is a classic late finding of tension pneumothorax caused by increasing pressure shifting the mediastinal structures.

🏵️ Because the injury is on the left side, deviation of the trachea toward the right side strongly supports a left tension pneumothorax.

🏵️ Other findings can include absent or markedly diminished breath sounds on the affected side, hypotension, tachycardia, distended neck veins, and respiratory distress.

🏵️ A tension pneumothorax is a life-threatening emergency requiring immediate decompression followed by definitive chest tube management.

Answer 8

Correct Answers:

Administer bronchodilators as prescribed.

Rationale :

♠️ The client is experiencing a severe acute asthma exacerbation, demonstrated by marked dyspnea, a respiratory rate of 35 breaths/minute, nasal flaring, and accessory muscle use.

♠️ Greatly diminished breath sounds are especially concerning because they can indicate extremely limited airflow through severely narrowed bronchi, sometimes described as a silent chest.

♠️ A silent or nearly silent chest during an asthma attack can indicate life-threatening airflow obstruction and impending respiratory failure.

♠️ A rapid-acting inhaled bronchodilator, typically a short-acting beta₂-agonist such as albuterol, directly treats the severe bronchoconstriction.

♠️ Bronchodilation relaxes bronchial smooth muscle, opens narrowed airways, and improves movement of air into and out of the lungs.

♠️ The nurse should rapidly reassess breath sounds, respiratory effort, respiratory rate, oxygen saturation, and level of consciousness after treatment.

♠️ Supplemental oxygen is also important when the client is hypoxemic, but the option requiring the nurse to wait 10 minutes before reassessment makes it less appropriate in this severely compromised client.

♠️ Therefore, among the available choices, immediate administration of the prescribed bronchodilator most directly addresses the life-threatening bronchoconstriction.

Answer 9

Correct Answers:

Avoid caffeinated beverages.

Rationale :

🖊️ Premature atrial complexes (PACs) are early electrical impulses that originate from an ectopic focus in the atria rather than the sinoatrial node.

🖊️ PACs can cause the sensation that the heart is skipping a beat, fluttering, or having palpitations.

🖊️ Occasional PACs are common and are often benign in clients without significant underlying cardiac disease.

🖊️ Caffeine is a stimulant that can increase sympathetic nervous system activity and may trigger or worsen palpitations in susceptible individuals.

🖊️ Common sources include coffee, tea, energy drinks, cola, and some medications or supplements containing caffeine.

🖊️ Other potential triggers for PACs include stress, alcohol, nicotine, fatigue, and certain stimulant medications.

🖊️ Reducing or avoiding an identified stimulant trigger such as caffeine can help decrease the frequency of symptomatic premature atrial beats.

🖊️ Therefore, teaching the client to avoid caffeinated beverages is the most appropriate intervention among the choices provided.

Answer 10

Correct Answers:

More P waves than QRS complexes.

Rationale :

🖍️ Third-degree heart block, also called complete heart block, occurs when atrial impulses are completely blocked from reaching the ventricles.

🖍️ The atria and ventricles beat independently because there is no electrical communication between them, producing AV dissociation.

🖍️ The P waves are generated by the sinoatrial node and usually occur at a faster rate than the ventricular escape rhythm.

🖍️ Consequently, the ECG typically shows more P waves than QRS complexes.

🖍️ The P-P intervals are regular, reflecting a regular atrial rhythm, while the R-R intervals are also regular, reflecting a separate ventricular rhythm.

🖍️ There is no consistent relationship between P waves and QRS complexes, so the PR interval varies.

🖍️ The slow ventricular escape rhythm can significantly reduce cardiac output, causing hypotension, dizziness, syncope, or altered mental status.

🖍️ Symptomatic complete heart block commonly requires pacing, with a permanent pacemaker often needed for definitive management.
