A nurse is assessing a client who has mitral valve stenosis Which of the following findings should the nurse except?
Clubbing of the fingers
A heart murmur
Barrel chest
Bradycardia
The Correct Answer is B
A) Clubbing of the fingers
Clubbing of the fingers is typically associated with chronic hypoxia, often due to conditions like chronic obstructive pulmonary disease (COPD), congenital heart defects, or chronic respiratory disorders. While mitral valve stenosis can lead to pulmonary congestion and sometimes hypoxia, clubbing is not a hallmark finding of mitral valve stenosis.
B) A heart murmur
Mitral valve stenosis is commonly characterized by a heart murmur. The stenosis (narrowing) of the mitral valve obstructs blood flow from the left atrium to the left ventricle, leading to turbulent blood flow. This creates a characteristic diastolic murmur (a low-pitched, rumbling murmur heard best at the apex of the heart with the patient in the left lateral decubitus position).
C) Barrel chest
A barrel chest is more commonly associated with chronic obstructive pulmonary disease (COPD), emphysema, and other conditions that cause long-term hyperinflation of the lungs. It is not a typical finding in mitral valve stenosis. The shape of the chest may change over time in patients with severe left-sided heart failure, but this is not a primary or direct consequence of mitral valve stenosis.
D) Bradycardia
Bradycardia (a slow heart rate) is not a characteristic finding of mitral valve stenosis. In fact, mitral valve stenosis can lead to increased heart rates due to reduced cardiac output and compensatory mechanisms. As the left atrium becomes increasingly distended from the obstruction, atrial fibrillation (a rapid, irregular heartbeat) is common in mitral valve stenosis.

Correct Answer is A
Explanation
A) Unstable:
Unstable angina is the type of angina most closely related to an impending myocardial infarction (MI). It is characterized by unpredictable chest pain that occurs at rest or with minimal exertion, or that increases in severity or frequency. Unstable angina represents a medical emergency and can progress to an MI if not promptly treated. It occurs when there is increased myocardial oxygen demand and a partially occluded coronary artery, often due to a ruptured atherosclerotic plaque.
B) Variant (Prinzmetal's) angina:
Variant angina, also known as Prinzmetal's angina, is caused by a spasm of the coronary artery, which temporarily narrows or obstructs blood flow. Although it can be severe and may occur at rest, it is typically transient and is not directly related to the development of an MI. Variant angina usually responds to medications such as nitrates or calcium channel blockers, and while it can be dangerous, it is not the most likely type of angina associated with a myocardial infarction.
C) Chronic stable angina:
Chronic stable angina occurs with predictable patterns, typically with exertion or stress, and resolves with rest or nitroglycerin. It does not usually indicate an impending MI, as it is a chronic condition caused by atherosclerosis that limits the heart's blood supply under stress. While chronic stable angina increases the risk of MI over time, it is not directly associated with an imminent heart attack.
D) Nocturnal angina:
Nocturnal angina refers to chest pain that occurs during the night or early morning hours, often during sleep. It may be associated with sleep apnea, GERD, or increased sympathetic tone during sleep. This type of angina is less commonly linked to an impending MI compared to unstable angina, although it should still be evaluated for any underlying cardiovascular issues.
Correct Answer is ["A","B","D"]
Explanation
A) Tachycardia: Tachycardia is commonly seen in left-sided heart failure as the heart attempts to compensate for the reduced cardiac output. To maintain adequate perfusion, the body increases the heart rate. The sympathetic nervous system is activated, causing an increase in heart rate to try to pump blood more efficiently despite the reduced pumping ability of the left ventricle.
B) Crackles: Crackles (also known as rales) are typically heard upon auscultation of the lungs in patients with left-sided heart failure. When the left ventricle fails to effectively pump blood, it causes blood to back up into the lungs, resulting in pulmonary congestion. This leads to fluid accumulation in the alveoli, causing crackling sounds during inhalation.
C) Ascites: Ascites is more commonly seen in right-sided heart failure or in cases of congestive heart failure where both sides of the heart are affected. Ascites is the accumulation of fluid in the abdomen, which is a consequence of right-sided heart failure causing blood to back up into the abdomen. In left-sided heart failure, ascites is generally not a primary symptom unless the failure becomes severe and involves both sides of the heart.
D) Dyspnea: Dyspnea, or shortness of breath, is a hallmark symptom of left-sided heart failure. The left ventricle's inability to pump blood efficiently leads to pulmonary congestion, which causes fluid to accumulate in the lungs. This fluid buildup reduces the lung's ability to exchange oxygen, resulting in difficulty breathing, especially on exertion or when lying down (orthopnea).
E) Peripheral edema: Peripheral edema is more characteristic of right-sided heart failure due to the backup of blood in the systemic circulation. While it can occur in cases of biventricular heart failure (both right and left sides of the heart are affected), it is not the primary finding in left-sided heart failure. Left-sided heart failure typically presents with pulmonary symptoms rather than systemic symptoms like peripheral edema.
