Correct Answer is C
Explanation
A. Incorrect. Continuous renal replacement therapy (CRRT) provides gradual and continuous removal of waste products and excess fluids from the blood, but it may not be as rapid as intermittent hemodialysis.
B. Incorrect. CRRT typically requires continuous sessions, which may last 24 hours or more. Intermittent hemodialysis involves shorter but more frequent sessions.
C. Correct. One of the primary advantages of CRRT is that it does not require the use of anticoagulants to prevent blood clotting in the machine. This reduces the risk of bleeding and other complications associated with anticoagulant use during hemodialysis.
D. Incorrect. The cost of CRRT and intermittent hemodialysis can vary based on the healthcare setting and the client's needs. The cost-effectiveness depends on individual factors and resource availability.
Correct Answer is B
Explanation
A. Incorrect. Increased heart rate and blood pressure are more commonly associated with metabolic alkalosis, not metabolic acidosis.
B. Correct. Muscle twitching and irritability are common clinical manifestations of metabolic acidosis. Acidosis can lead to an increase in excitability of nerve cells, causing muscle twitching and irritability.
C. Incorrect. Excessive thirst and frequent urination are not typically associated with metabolic acidosis.
D. Incorrect. Warm, flushed skin and headache are not directly related to metabolic acidosis.
