A patient's ABG results are: pH 7.50, PCO2 25, HCO3 25, PO2 80. Which finding should the nurse expect as the body compensates for the acid-base imbalance?
The kidneys will excrete more HCO3 into the urine.
The respiratory system will increase RR.
The kidneys will create more HCO3.
The respiratory system will decrease respiratory rate (RR).
The Correct Answer is D
A. While the kidneys do excrete HCO3 to help in metabolic compensation, this process is slower than respiratory compensation.
B. An increase in respiratory rate would further decrease CO2, worsening the alkalosis rather than compensating for it.
C. Creating more HCO3 would not compensate for respiratory alkalosis and would actually increase the pH further.
D. The body will decrease the respiratory rate to retain more CO2, helping to lower the pH and partially correct the alkalosis.

Correct Answer is A
Explanation
A. ACE inhibitors block the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor in the RAAS, which leads to decreased blood pressure by promoting vasodilation.
B. The RAAS is primarily a vasoconstrictive system, and ACE inhibitors reduce this vasoconstriction, not vasodilation.
C. ACE inhibitors do not directly affect the inotropic (force of contraction) effects of the SNS; they work on the RAAS.
D. While natriuretic peptides help regulate fluid balance, ACE inhibitors do not directly impact this system.
Correct Answer is A
Explanation
A. Long-term hypertension can lead to renal damage, resulting in glomerular injury and subsequent hematuria and proteinuria. ACE inhibitors help to protect renal function by reducing pressure in the glomeruli.
B. Venous insufficiency is generally not a direct complication of hypertension; it is more associated with conditions affecting venous return.
C. Increased elastase activity is related to the breakdown of elastin and is not a direct consequence of hypertension or the primary focus of ACE inhibitor therapy.
D. Decreased high-density lipoproteins (HDL) is not a direct complication of hypertension and does not specifically relate to the effects of ACE inhibitors.
