The nurse is assessing a client with a diagnosis of mitral valve stenosis. Which element of assessment data indicates that the disease is worsening?

Increase in systolic blood pressure 10 mmHg above client's norm

reports dyspnea after walking up 2 flights of stairs

Jugular vein distention and +3 peripheral edema

Complaints of epigastric pain after eating a large meal

Answer and Explanation

The Correct Answer is C

A. Increase in systolic blood pressure 10 mmHg above client's norm: A mild increase in systolic blood pressure is not a specific indicator of mitral stenosis progression. Blood pressure fluctuations may occur due to various factors and are not typically used as a primary marker of worsening valve disease.

B. reports dyspnea after walking up 2 flights of stairs: Exertional dyspnea is a common early symptom of mitral stenosis due to reduced left atrial emptying and pulmonary congestion. However, this does not necessarily indicate worsening unless the symptom becomes more severe or occurs with minimal exertion.

C. Jugular vein distention and +3 peripheral edema: These are signs of right-sided heart failure, which may result from long-standing mitral stenosis leading to pulmonary hypertension and subsequent right ventricular hypertrophy and failure. This indicates disease progression and worsening cardiac function.

D. Complaints of epigastric pain after eating a large meal: Epigastric discomfort is not a typical symptom of mitral stenosis and is more likely related to gastrointestinal issues. It does not reflect the status or progression of the cardiac condition.

Correct Answer is D

Explanation

A. Blood pressure reading of 120/80: While a normal blood pressure is desirable, this value alone does not indicate improvement in fluid overload or pulmonary symptoms. It may remain normal even if respiratory status worsens or fails to improve.

B. Urine output 30 mL for one hour: Although urine output is an important measure of diuretic effectiveness, 30 mL/hr is the minimum acceptable rate, not necessarily a strong indicator of clinical improvement. More robust diuresis may be expected following IV furosemide.

C. Serum sodium level is 135 mEq/L (135–145): A normal sodium level reflects stable electrolyte status but does not directly indicate improvement in pulmonary congestion or dyspnea. Sodium may be affected by many factors unrelated to heart failure symptom relief.

D. Respiratory rate 16 per minute: A decrease in respiratory rate from 26 to 16 suggests improved oxygenation, reduced pulmonary congestion, and decreased work of breathing. It is the most direct and clinically relevant indicator of symptomatic improvement in this context.

A. hypermagnesemia. B. hypocalcemia. C. hypokalemia. D. hyperglycemia.

Correct Answer is C

Explanation

A. Hypermagnesemia: Hypermagnesemia (high magnesium levels) can cause bradycardia, hypotension, and prolonged PR and QRS intervals. While it can affect cardiac rhythm, it's less commonly associated with PVCs. The client's magnesium level of 2.5 mg/dL is within the normal range (1.5-2.5 mg/dL).

B. Hypocalcemia: While the calcium level of 8.0 mg/dL is slightly low (normal: ~8.5–10.5 mg/dL), mild hypocalcemia is less commonly associated with PVCs compared to hypokalemia. It can affect cardiac contractility but is not the most likely cause of these arrhythmias.

C. Hypokalemia: The potassium level is 2.8 mEq/L, which is significantly below normal (normal: 3.5–5.0 mEq/L). Potassium is a crucial electrolyte for maintaining normal cardiac electrical activity. Hypokalemia increases myocardial excitability and can lead to various cardiac dysrhythmias and a known cause of ventricular irritability, including multifocal PVCs, and increases the risk of life-threatening arrhythmias in clients with cardiac or metabolic conditions.

D. Hyperglycemia: The glucose level of 200 mg/dL is elevated but not severely high. While it reflects poor glycemic control, it is not directly linked to the occurrence of PVCs. Electrolyte imbalances, particularly low potassium, are more arrhythmogenic.
