A patient has had chronic kidney disease (CKD) for many years. The patient sustains a hip fracture. The high risk of fractures is related to a(n)

inability of the kidneys to produce erythropoietin.

increased ability to absorb calcium from the foods that are eaten.

decreased ability of the kidneys to activate vitamin D.

decreased serum phosphate.

Answer and Explanation

The Correct Answer is C

A. While CKD does reduce erythropoietin production, this affects anemia rather than bone health or fracture risk.

B. CKD often leads to decreased calcium absorption due to impaired vitamin D activation, not an increased absorption. C. In CKD, the kidneys lose the ability to convert vitamin D to its active form, impairing calcium absorption from the intestine and weakening

Correct Answer is D

Explanation

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.

A. hypertension; vision test B. left heart failure; b-type natriuretic peptide (BNP) C. aspiration pneumonia; arterial blood gas (ABG) D. chronic bronchitis; peak flow

Correct Answer is D

Explanation

A. Hypertension may contribute to cardiovascular issues, but it does not typically cause cyanosis or clubbing.

B. Left heart failure often leads to symptoms like dyspnea and fluid retention but does not commonly cause clubbing of the fingers.

C. Aspiration pneumonia may cause respiratory symptoms, but clubbing is more associated with chronic hypoxia, seen in conditions like chronic bronchitis.

D. Chronic bronchitis, often seen in chronic obstructive pulmonary disease (COPD), can cause long-term hypoxia, leading to cyanosis and clubbing of the fingers. A peak flow test can assess respiratory function and airflow limitations associated with chronic bronchitis.
