A physician who is providing care for a 71-year-old male client with a recent diagnosis of renal failure and an acid-base imbalance is explaining some of the underlying etiology of the man's diagnoses to him and his family.
 
  Which of the following phenomena would most accurately underlie the teaching that the physician provides?
  A)
  The kidneys are integral to the reabsorption of hydrogen ions and maintenance of a low pH.
  B)
  Blood buffer systems and respiratory control can compensate for inadequate renal control of pH.
  C)
  The kidneys have the primary responsibility for eliminating excess hydrogen ions from the body.
  D)
  pH is kept at an optimal level through the renal secretion of bicarbonate ions in blood filtrate.

Question 2

Following electrophysiologica l testing that included ablation therapy, the nurse should be assessing the patient for which complication that may occur postprocedure?
 
  A)
  Complaints of nausea and spitting up bile-looking secretions along with stomach cramps
  B)
  Sudden onset of dysonea, tachypnea, and chest pain of a pleuritic nature (worsened by breathing)
  C)
  Bleeding from the nose that requires packing, excessive swallowing of mucus, and coughing
  D)
  Complaints of heart palpitations, frequent PVCs noted on monitor, and substernal chest pain

Answer to Question 1

Ans:
C

Feedback:

The kidneys have the primary responsibility for maintaining body pH by eliminating excess hydrogen ions from the body, a function that blood buffer systems and respiratory control are incapable of. Hydrogen ions must be eliminated, not retained, and bicarbonate must be produced as part of buffer action, not secreted.

Answer to Question 2

Ans:
B

Feedback:

Following EPS that included an ablation, the procedure increases the risk of complications, which include venous thrombosis and pulmonary emboli. Answer choice B refers to s/s of pulmonary emboli. Answer choice A refers to GI symptoms, which are not associated with EPS. Answer choice C refers that this procedure does not place a tube down the nose/throat. Answer choice D refers that EPS usually does not involve the left side of the heart; therefore, the risk of MI is minimal.
