patient nurse monitor closely respiratory alkalosis quizlet

Which patient should the nurse monitor closely for respiratory alkalosis Quizlet

Correct answer
Ventricular fibrillation

Rationale:
COPD complications may cause respiratory acidosis from hypoventilation and the buildup of carbon dioxide. Respiratory acidosis causes a compensatory hyperkalemia as the H+ move into the cells to maintain the pH of the blood; however, when H+ moves in, potassium is kicked out during the exchange. Increased serum K+ levels affect cardiac conduction and irritability as cardiac depolarization decreases, leading to the loss of P waves, prolonged PR interval, ST segment depression, and widening QRS complexes. Heart block, ventricular fibrillation, or cardiac standstill may occur. Diarrhea, confusion, and abdominal pain are manifestations of metabolic acidosis.

Who is at risk for respiratory alkalosis?

Who is at risk for respiratory alkalosis? People who experience intense bouts of stress, anxiety, panic or anger are at higher risk for respiratory alkalosis. These conditions can lead to rapid, uncontrolled breathing (hyperventilation). People on breathing machines (mechanical ventilation) are also at risk.

Which of the following would indicate respiratory alkalosis?

Symptoms of respiratory alkalosis Overbreathing is a sign that respiratory alkalosis is likely to develop. However, low carbon dioxide levels in the blood also have a number of physical effects, including: dizziness. bloating.

Which would the nurse recognize as the most common cause of respiratory alkalosis?

Respiratory alkalosis is caused by hyperventilation that can occur due to anxiety, panic attacks, pain, fear, head injuries, or mechanical ventilation. Overdoses of salicylates and other toxins can also cause respiratory alkalosis initially and then often progress to metabolic acidosis in later stages.

Which of the following is most likely to result in respiratory alkalosis quizlet?

Which of the following problems is most likely? Causes of respiratory alkalosis in patients with normal lungs include anxiety, fever, stimulant drugs, CNS lesions, pain and sepsis. On the other hand, respiratory alkalosis in those with cardiopulmonary disorders is most likely due to arterial hypoxemia.
