Question 1
Regular
When assessing a client, what sign would the nurse know is an early sign of an impending heart failure?
Correct!
Incorrect
The correct answer is: B
Rationale
S3 heart sound signifies early heart failure as it reflects increased volume and pressure within the ventricles, indicating a decline in cardiac function. This sound is often associated with fluid overload and can be an early warning sign for clinicians.
A: S1 heart sound This sound represents normal closure of heart valves and does not indicate impending heart failure or fluid overload. It is typically associated with a healthy heart function.
C: Heart murmur A heart murmur indicates turbulent blood flow but is not a direct sign of heart failure. Murmurs can result from various conditions unrelated to heart function deterioration.
D: Crackles Although crackles can signify fluid in the lungs, they are more associated with established heart failure rather than an early sign. They indicate more advanced pulmonary congestion.

Question 5
Regular
The nurse is caring for a client with a valvular disorder. The client is at risk for decreased cardiac output. What nursing intervention should a nurse perform for this client?
Correct!
Incorrect
The correct answer is: D
Rationale
Measure urine output.
Monitoring urine output provides critical insight into the client’s renal function and fluid balance, which are directly impacted by cardiac output. This intervention helps detect early signs of complications and informs necessary adjustments in treatment to manage the valvular disorder effectively.
A: Perform exercises consistently. Exercise may not be appropriate for a client at risk for decreased cardiac output, as it could exacerbate their condition rather than improve it.
B: Keep legs horizontal. Maintaining a horizontal leg position does not address the underlying issues of decreased cardiac output and may not aid in monitoring the client’s condition effectively.
C: Auscultate lung and heart sounds. While auscultation is important, it does not provide direct quantitative data on the client’s kidney perfusion or fluid status, which is crucial in managing their condition.

Question 6
Regular
A client with aortic valve regurgitation is asking about the disease process. What would the nurse tell the client is the first sign of aortic valve regurgitation?
Correct!
Incorrect
The correct answer is: A
Rationale
A: Tachycardia. The initial sign of aortic valve regurgitation often manifests as tachycardia, as the heart compensates for reduced stroke volume by increasing the heart rate to maintain adequate perfusion.
B: Left-sided heart failure. While left-sided heart failure may develop later, it does not represent the initial symptom, as the body first responds with increased heart rate.
C: Pain. Pain is not a typical early sign of aortic valve regurgitation; rather, it is associated with other cardiac conditions and does not directly indicate valve dysfunction.
D: Dysrhythmias. Although dysrhythmias can occur as the condition progresses, they are not the foremost indication of aortic valve regurgitation, which is primarily characterized by increased heart rate.

Question 11
Regular
A client reports a family history of aortic stenosis. Which assessment finding would the nurse identify as a likely contributing factor?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Missing aortic cusp. Aortic stenosis, particularly in familial cases, often stems from congenital abnormalities such as the absence of an aortic cusp, which hinders normal blood flow and increases pressure on the heart.
A: High blood pressure. Although hypertension can exacerbate heart issues, it does not directly contribute to the structural defect of aortic stenosis, making it less relevant in this context.
C: Unidirectional blood flow. This term describes normal hemodynamics rather than structural abnormalities, failing to address the anatomical causes of aortic stenosis, particularly those linked to familial history.
D: Chest pain. While chest pain may arise from aortic stenosis, it represents a symptom rather than a contributing factor, lacking the causative association required for this specific inquiry.

Question 19
Regular
The nurse collects data for a client who is diagnosed with mitral stenosis with a murmur. In which position does the nurse place the client to auscultate the documented murmur?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Left lateral. This position facilitates optimal auscultation of the mitral valve, allowing the nurse to better hear the murmur associated with mitral stenosis, as it enhances heart sounds and reduces lung interference.
A: Prone. This position compresses the chest and may hinder the nurse's ability to clearly hear heart sounds, including murmurs, making it unsuitable for auscultation of mitral stenosis.
B: Supine. While this position allows for heart sound assessment, it does not provide the same clarity as the left lateral position, potentially obscuring the murmur's characteristics.
D: Right lateral. This position is less favorable for auscultating the mitral valve, as it can obscure sounds coming from the left side of the heart where the mitral murmur is located.
Correct Answer: C

Question 20
Regular
The nurse is caring for a client diagnosed with mitral stenosis. Which client symptom change would most likely indicate to the nurse, a progression of this condition?
Correct!
Incorrect
The correct answer is: A
Rationale
Decreased systolic pressure indicates a progression of mitral stenosis due to the heart's inability to effectively pump blood through a narrowed valve, leading to reduced cardiac output and systemic circulation issues.
B: Increased systolic pressure suggests heightened cardiac output or compensatory mechanisms, which does not align with the typical deterioration associated with mitral stenosis, where output tends to decrease.
C: Widening pulse pressure typically indicates conditions like aortic regurgitation rather than mitral stenosis, where the focus is on decreased systolic pressure due to impaired blood flow.
D: Normal diastolic pressure does not signify disease progression; instead, it reflects stable diastolic function, which is not indicative of worsening mitral stenosis symptoms.

Rationale
Pulmonary edema. The presence of a productive cough with pink, frothy sputum in a client with mitral stenosis suggests fluid accumulation in the lungs, typically indicative of pulmonary edema, necessitating further evaluation for this serious complication.
B: Congestive failure Significant heart dysfunction is implied, but the specific symptom of pink, frothy sputum directly points more towards pulmonary edema than generalized congestive heart failure.
C: Thrombophlebitis Symptoms of thrombophlebitis involve swelling and pain in the leg, not respiratory distress or cough, making it irrelevant in this context of pulmonary complications.
D: Cardiogenic shock While cardiogenic shock involves heart failure, it usually presents with different symptoms like hypotension and altered consciousness, not specifically with pink, frothy sputum.
Correct Answer: A

Question 23
Regular
The nurse is interviewing a client who is being admitted for possible mitral regurgitation. Which historical fact is of greatest value to the nurse?
Correct!
Incorrect
The correct answer is: B
Rationale
Rheumatic fever is of greatest value to the nurse in assessing potential mitral regurgitation. This condition often results from rheumatic fever, which can lead to valve damage and dysfunction, thus providing critical insight into the client’s cardiac history and current health status.
A: Congenital neural tube defect This condition primarily affects the spinal cord and brain development, making it less relevant to the assessment of mitral regurgitation and its potential causes.
C: One-pack-a-day smoker for 20 years While smoking significantly impacts cardiovascular health, it does not directly relate to the specific etiology of mitral regurgitation, which is more closely linked to rheumatic fever.
D: Pacemaker inserted 2 years ago The presence of a pacemaker suggests prior arrhythmias but does not directly inform the nurse about the possible causes or history of mitral regurgitation.

Question 24
Regular
The nurse provides care for an older adult client who is diagnosed with valvular heart disease. On auscultation of the client's heart sounds, the nurse notes an erratic heart rhythm. Which age-related change is the most likely cause for this finding?
Correct!
Incorrect
The correct answer is: A
Rationale
A stiffening of the aorta leads to changes in heart dynamics, contributing to an erratic heart rhythm in older adults. This age-related alteration affects blood flow and cardiac output, resulting in abnormal heart sounds during auscultation.
B: A decrease in metabolism A reduction in metabolic rate does not directly influence heart rhythm; instead, it primarily affects energy expenditure and overall physiological functions without altering cardiac electrical activity.
C: An increase in thirst sensation Enhanced thirst sensation is unrelated to heart rhythm changes; it typically pertains to hydration status and does not impact cardiovascular function or the characteristics of heart sounds.
D: A thinning of the mitral valve While mitral valve thinning can affect heart function, it is unlikely to be the primary cause of an erratic rhythm compared to aortic stiffening in older adults.

Question 25
Regular
The nurse is caring for a client with mitral stenosis. Which assessment finding would cause the greatest concern in providing nursing care to this client?
Correct!
Incorrect
The correct answer is: A
Rationale
Increased left atrial pressure is the assessment finding that would cause the greatest concern in providing nursing care to a client with mitral stenosis.
Elevated left atrial pressure indicates worsening blood flow obstruction due to mitral stenosis, leading to potential pulmonary congestion and heart failure. Monitoring this parameter is crucial for assessing the severity of the condition and guiding appropriate nursing interventions.
B: Increased cardiac output This finding suggests the heart is effectively pumping blood, which is generally not a primary concern in mitral stenosis and can be misleading in evaluation.
C: Decreased right ventricular pressure Lower right ventricular pressure does not directly affect mitral stenosis and could indicate improved right heart function, which is not a primary concern in this condition.
D: Decreased pulmonary pressure Lower pulmonary pressure may indicate reduced burden on the lungs, which is typically not a significant concern in the context of mitral stenosis and its complications.

Question 26
Regular
Before an invasive procedure, a client is prescribed antibiotics. The nurse understands the reason for this preventative action is to avoid which complication?
Correct!
Incorrect
The correct answer is: B
Rationale
Infective endocarditis is the complication that antibiotics aim to prevent before an invasive procedure. This condition involves inflammation of the heart's inner lining due to bacterial infection, which can occur during such procedures.
A: Cardiogenic shock occurs due to heart dysfunction and is not directly related to infection prevention with antibiotics prior to invasive procedures.
C: Congestive heart failure results from various cardiac issues, not from bacterial infections linked to invasive procedures requiring prophylactic antibiotics.
D: Rheumatic heart disease is a result of untreated streptococcal infections, but antibiotics before procedures specifically target the prevention of infective endocarditis, not this condition.

Question 27
Regular
Before administering digoxin to a client with valvular disease, the nurse assesses the apical heart rate as 62 beats/minute. The client's usual rate ranges between 66 to 72 beats/minute. Which is the best action for the nurse to take?
Correct!
Incorrect
The correct answer is: C
Rationale
Administer the digoxin. The apical heart rate of 62 beats/minute, while below the usual range, does not indicate immediate concern, especially if the client has stable hemodynamics and no signs of distress.
A: Hold the digoxin. The heart rate, although lower than normal, does not necessitate withholding the medication without other concerning symptoms being present.
B: Recheck the apical pulse in 30 minutes. Delaying medication administration without valid reasons could result in inadequate treatment for the client's condition, potentially worsening their health status.
D: Notify the physician. There is no immediate need to inform the physician, as the heart rate does not indicate a critical situation that requires urgent intervention or alteration of the treatment plan.

Question 28
Regular
A client with progressive mitral valve prolapse is experiencing sympathetic nervous system symptoms in addition to prolapse symptoms. Which teaching point should be stressed by the nurse to minimize these effects?
Correct!
Incorrect
The correct answer is: C
Rationale
Avoid caffeine. Caffeine can exacerbate sympathetic nervous system symptoms, leading to increased heart rate and anxiety in patients with mitral valve prolapse. Educating the client about reducing or eliminating caffeine intake helps manage these distressing symptoms effectively.
A: Antibiotic therapy before invasive procedures. This recommendation pertains to infection prevention but does not address the sympathetic symptoms linked to mitral valve prolapse.
B: Low-dose aspirin daily. While aspirin may reduce clot risk in some patients, it does not alleviate the sympathetic nervous system symptoms associated with mitral valve prolapse.
D: Decrease fluid and sodium intake. This teaching point may not specifically target the management of sympathetic symptoms, which are more directly affected by stimulant intake rather than fluid or sodium levels.
