1. The triage nurse notes upon assessment in the emergency room that the patient with anxiety is hyperventilating. The nurse is aware that hyperventilation is the most common cause of which acid-base imbalance?

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation is the most common cause of acute respiratory alkalosis. When a patient hyperventilates due to anxiety or other causes, they blow off excessive carbon dioxide, leading to a decrease in PaCO2 and a rise in pH. Choices A, C, and D are incorrect because hyperventilation leads to a decrease in PaCO2, causing respiratory alkalosis, not respiratory acidosis, metabolic acidosis, or metabolic alkalosis.

2. Which substance dissociates into ions in a water solution?

Correct answer: D

Rationale: The correct answer is 'Electrolyte.' Electrolytes are substances that dissociate into ions when dissolved in water. Intracellular fluid, interstitial fluid, and plasma are not substances that dissociate into ions in a water solution. Intracellular fluid is the fluid inside cells, interstitial fluid is the fluid between cells, and plasma is the liquid component of blood. These choices do not dissociate into ions in a water solution, unlike electrolytes.

3. A patient who is hospitalized with a possible electrolyte imbalance is disoriented and weak, has an irregular pulse, and takes hydrochlorothiazide. He most likely suffers from:

Correct answer: D

Rationale: The patient is displaying symptoms of hypokalemia, including weakness, disorientation, irregular pulse, which can lead to cardiac disturbances. Hydrochlorothiazide is a potassium-wasting diuretic that can cause hypokalemia if not accompanied by potassium replacement therapy. Hypernatremia (choice A) is characterized by high sodium levels, not potassium. Hyponatremia (choice B) is low sodium levels. Hyperkalemia (choice C) is high potassium levels, which is not consistent with the symptoms described in the question.

4. A medical-surgical nurse is concerned about the incidence of complications related to IV therapy, including bloodstream infection. Which intervention should the nurse suggest to the management team to make the biggest impact on decreasing complications

Correct answer: A

Rationale:

5. A nurse is planning care for a client who is hyperventilating. The clients arterial blood gas values are pH 7.30, PaO2 94 mm Hg, PaCO2 31 mm Hg, and HCO3 26 mEq/L. Which question should the nurse ask when developing this clients plan of care?

Correct answer: B

Rationale:
