Nursing Elites

1. You are making initial shift assessments on your patients. While assessing one patients peripheral IV site, you note edema around the insertion site. How should you document this complication related to IV therapy?

• A. Air emboli
• B. Phlebitis
• C. Infiltration
• D. Fluid overload

Correct answer: C

Rationale:

2. A nurse assesses a client who is admitted with an acid-base imbalance. The clients arterial blood gas values are pH 7.32, PaO2 85 mm Hg, PaCO2 34 mm Hg, and HCO3 16 mEq/L. What action should the nurse take next?

• A. Assess clients rate, rhythm, and depth of respiration.
• B. Measure the clients pulse and blood pressure.
• C. Document the findings and continue to monitor.
• D. Notify the physician as soon as possible.

Correct answer: A

Rationale:

3. A patient who is being treated for pneumonia starts complaining of sudden shortness of breath. An arterial blood gas (ABG) is drawn. The ABG has the following values: pH 7.21, PaCO2 64 mm Hg, HCO3 = 24 mm Hg. What does the ABG reflect?

• A. Respiratory acidosis
• B. Metabolic alkalosis
• C. Respiratory alkalosis
• D. Metabolic acidosis

Correct answer: A

Rationale:

4. A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause of which acid-base imbalance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Increased PaCO2
• D. CNS disturbances

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation, which can be caused by extreme anxiety, is the most common cause of acute respiratory alkalosis. This leads to a decrease in PaCO2 levels. Respiratory acidosis, choice A, occurs in conditions like hypoventilation, leading to an increase in PaCO2 levels. Choice C, Increased PaCO2, is not the correct term for an acid-base imbalance related to hyperventilation. Choice D, CNS disturbances, is not directly related to the acid-base imbalance caused by hyperventilation.

5. You are called to your patients room by a family member who voices concern about the patients status. On assessment, you find the patient tachypnic, lethargic, weak, and exhibiting a diminished cognitive ability. You also find 3+ pitting edema. What electrolyte imbalance is the most plausible cause of this patients signs and symptoms?

• A. Hypocalcemia
• B. Hyponatremia
• C. Hyperchloremia
• D. Hypophosphatemia

Correct answer: C

Rationale:
