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).

Answer and Explanation

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 B

Explanation

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.

A. benign prostatic hypertrophy (BPH). B. ovarian cancer. C. a kidney stone. D. a chlamydia infection.

Correct Answer is D

Explanation

A. Benign prostatic hypertrophy is a condition affecting the prostate in men, so it is not applicable in this case.

B. Ovarian cancer may cause pelvic pain, but the specific symptoms of abnormal discharge and acute pain suggest a more immediate infection rather than cancer.

C. A kidney stone typically presents with flank pain and may cause urinary symptoms, but it would not typically cause vaginal discharge.

D. A chlamydia infection can cause abnormal vaginal discharge and pelvic pain, and it is a common sexually transmitted infection presenting with these symptoms, consistent with the patient's history.
