A patient diagnosed with cor pulmonale would most benefit from _because_______

an ACE-inhibitor medication: it will act as an inotrope and help to eliminate murmurs.

a diuretic: it will decrease preload and therefore decrease the workload of the heart.

a lab check of his troponin level: a troponin level will distinguish between right and left ventricular failure

a diuretic: it will counteract the dehydration present in most cases of cor pulmonale.

Answer and Explanation

The Correct Answer is B

A. While ACE inhibitors can be beneficial for heart failure management, they do not specifically eliminate murmurs and are not primarily used as inotropes in cor pulmonale management.
B. Cor pulmonale, characterized by right heart failure due to lung disease, often leads to fluid overload. A diuretic helps to decrease preload by promoting diuresis, thus reducing the workload on the heart and alleviating symptoms of congestion.
C. Troponin levels are used to assess myocardial injury rather than to distinguish between right and left ventricular failure; this is not a primary concern in cor pulmonale management.
D. Cor pulmonale is typically associated with volume overload rather than dehydration; therefore, using a diuretic to counteract dehydration is incorrect. The focus should be on reducing excess fluid to manage heart failure symptoms.

Correct Answer is D

Explanation

A. Chancres are not associated with glomerulonephritis; this option is incorrect as it refers to syphilis, which does not cause this condition.

B. Glomerulonephritis typically leads to decreased urine output due to reduced GFR, not increased urine output.

C. Poor skin turgor is usually indicative of dehydration rather than hyperproteinemia; in glomerulonephritis, the issue is typically a loss of proteins in the urine, leading to edema.

D. In post-streptococcal glomerulonephritis, hypoproteinemia (loss of protein due to kidney damage) causes fluid to shift from the vascular space to tissues, resulting in edema.

A. Bleeding in the brain. B. Anxiety. C. Kidney failure. D. Extreme vomiting.

Correct Answer is C

Explanation

A. Bleeding in the brain could cause neurological symptoms but does not directly correlate with the respiratory acidosis indicated by the ABGs.

B. Anxiety typically leads to respiratory alkalosis due to hyperventilation, which does not align with the results showing acidemia.

C. The ABG results indicate a primary respiratory acidosis (low pH and elevated PCO2), which can occur in kidney failure due to the kidneys' inability to excrete acids and manage bicarbonate, leading to an accumulation of CO2.

D. Extreme vomiting is associated with metabolic alkalosis due to loss of gastric acid, which does not explain the acid-base disturbance presented.
