Nursing Elites

1. How should the nurse interpret the following arterial blood gas results for a patient who had a tracheostomy placed after a motor vehicle crash: pH 7.48, PaO2 85 mm Hg, PaCO2 32 mm Hg, and HCO3 25 mEq/L?

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

Correct answer: D

Rationale: The patient's pH of 7.48 indicates alkalosis, and the low PaCO2 of 32 mm Hg suggests a respiratory cause. The HCO3 level is normal, ruling out metabolic causes. Therefore, the correct interpretation is respiratory alkalosis. Options A, B, and C are incorrect as they do not align with the pH and PaCO2 values provided.

2. The nurse assesses a patient who has been hospitalized for 2 days. The patient has been receiving normal saline IV at 100 mL/hr, has a nasogastric tube to low suction, and is NPO. Which assessment finding would be a priority for the nurse to report to the health care provider?

• A. Oral temperature of 100.1°F
• B. Serum sodium level of 138 mEq/L (138 mmol/L)
• C. Gradually decreasing level of consciousness (LOC)
• D. Weight gain of 2 pounds (1 kg) above the admission weight

Correct answer: C

Rationale: The priority assessment finding for the nurse to report to the healthcare provider is a gradually decreasing level of consciousness (LOC). This change in LOC could indicate fluid and electrolyte disturbances, which require immediate attention to prevent complications. While the other options such as an elevated temperature, serum sodium level, and weight gain are important to note and report, they do not indicate an urgent need for intervention compared to changes in LOC which could signify serious issues that need prompt evaluation and management.

3. A patient comes to the clinic complaining of frequent, watery stools for the last 2 days. Which action should the nurse take first?

• A. Obtain the baseline weight
• B. Check the patient’s blood pressure
• C. Draw blood for serum electrolyte levels
• D. Ask about any extremity numbness or tingling

Correct answer: B

Rationale: The correct answer is to check the patient’s blood pressure. Given the patient's symptoms of frequent, watery stools, there is a concern for fluid volume deficit. Assessing the blood pressure helps determine the patient's perfusion status, which is crucial in managing fluid volume deficits. While obtaining baseline weight, drawing blood for serum electrolyte levels, and asking about extremity numbness or tingling are important assessments, checking the blood pressure takes precedence as it provides immediate information on the patient's circulatory status.

4. A client with bladder cancer had surgical placement of a ureteroileostomy (ileal conduit) yesterday. Which postoperative assessment finding should the nurse report to the healthcare provider immediately?

• A. red and edematous stoma appearance
• B. liquid brown drainage from stoma
• C. stoma output of 40ml in the last hour
• D. mucous strings floating in the drainage

Correct answer: C

Rationale: Stoma output of only 40ml in the last hour may indicate a problem, such as dehydration or blockage, and should be reported immediately. A red and edematous stoma appearance could be due to inflammation, which is expected in the early postoperative period. Liquid brown drainage from the stoma is a normal finding. Mucous strings floating in the drainage are also a common occurrence postoperatively and do not typically require immediate reporting.

5. A postoperative patient who had surgery for a perforated gastric ulcer has been receiving nasogastric suction for 3 days. The patient now has a serum sodium level of 127 mEq/L (127 mmol/L). Which prescribed therapy should the nurse question?

• A. Infuse 5% dextrose in water at 125 mL/hr.
• B. Administer IV morphine sulfate 4 mg every 2 hours PRN.
• C. Give IV metoclopramide (Reglan) 10 mg every 6 hours PRN for nausea.
• D. Administer 3% saline if serum sodium decreases to less than 128 mEq/L.

Correct answer: A

Rationale: The nurse should question the prescription to infuse 5% dextrose in water at 125 mL/hr because the patient's gastric suction has been depleting electrolytes, leading to hyponatremia. Therefore, the IV solution should include electrolyte replacement. Solutions like lactated Ringer’s solution would usually be ordered. The other choices (B, C, and D) are appropriate for a postoperative patient with gastric suction, addressing pain management, nausea control, and correcting hyponatremia if it drops below a certain level.
