In respiratory acidosis, what is the priority intervention?

• Improving ventilation

• Administering sodium bicarbonate

• Using rebreathing techniques

• Administering antiemetics

Answer explanation

In respiratory acidosis, the primary issue is inadequate ventilation leading to CO2 retention. Improving ventilation directly addresses this problem, making it the priority intervention over other options.

What is the goal of interventions for respiratory alkalosis?

• Reduce the breathing rate and restore CO₂ balance

• Improve ventilation and remove retained CO₂

• Correct the acid buildup or replace lost bicarbonate

• Stop the loss of acids or reduce base levels

Answer explanation

The goal of interventions for respiratory alkalosis is to reduce the breathing rate and restore CO₂ balance, as hyperventilation leads to decreased CO₂ levels, causing alkalosis.

Which intervention is used for metabolic acidosis in severe cases?

• Administer IV sodium bicarbonate

• Use rebreathing techniques

• Administer bronchodilators

• Give antiemetics

Answer explanation

In severe metabolic acidosis, administering IV sodium bicarbonate helps to neutralize excess acid in the body, restoring pH balance. Other options like rebreathing techniques or bronchodilators are not effective for this condition.

What should nurses monitor across all imbalances?

• ABGs and lab values

• Only respiratory effort

• Only level of consciousness

• Only vital signs

Answer explanation

Nurses should monitor ABGs and lab values across all imbalances as they provide critical information about a patient's respiratory and metabolic status, ensuring comprehensive assessment and appropriate interventions.

Which of the following is a common cause of metabolic alkalosis?

• Chronic lung disease

• Prolonged vomiting

• Renal failure

• Diabetic ketoacidosis

What is the primary goal when treating metabolic alkalosis?

• Restore fluid and electrolyte balance

• Administer bronchodilators

• Reduce oxygen therapy

• Increase CO₂ retention

Which laboratory value is most important to monitor in a patient with acid-base imbalance?

• White blood cell count

• Blood glucose

• Serum calcium

• Arterial blood gases (ABGs)

Which of the following conditions is most likely to cause respiratory acidosis?

• Diuretic overuse

• Prolonged vomiting

• Hyperventilation

• Chronic obstructive pulmonary disease (COPD)

What is a typical sign of metabolic acidosis in a patient?

• Kussmaul respirations

• Muscle twitching

• Bradycardia

• Slow, shallow breathing

Which electrolyte imbalance is commonly associated with acid-base disturbances?

• Hypoglycemia

• Hypernatremia

• Hypercalcemia

• Hyperkalemia
