Nursing Elites

1. 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.

2. After receiving change-of-shift report, which patient should the nurse assess first?

• A. Patient with a serum potassium level of 5.0 mEq/L who is complaining of abdominal cramping
• B. Patient with a serum sodium level of 145 mEq/L who has a dry mouth and is asking for a glass of water
• C. Patient with a serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes
• D. Patient with a serum phosphorus level of 4.5 mg/dL who has multiple soft tissue calcium-phosphate precipitates

Correct answer: C

Rationale: The correct answer is patient C with a serum magnesium level of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes. The low magnesium level and neuromuscular irritability suggest that the patient may be at risk for seizures, which are life-threatening. Assessing and addressing this patient's condition promptly is crucial to prevent complications. Patients A, B, and D have mild electrolyte disturbances or symptoms that require attention, but they are not at immediate risk for life-threatening complications like seizures, unlike patient C.

3. 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.

4. A patient is admitted for hypovolemia associated with multiple draining wounds. Which assessment would be the most accurate way for the nurse to evaluate fluid balance?

• A. Skin turgor
• B. Daily weight
• C. Presence of edema
• D. Hourly urine output

Correct answer: B

Rationale: Daily weight is the most easily obtained and accurate means of assessing volume status. Skin turgor varies considerably with age and can be affected by various factors other than fluid balance. Presence of edema indicates excess fluid has moved into the interstitial space, which may not always be directly correlated with overall fluid balance. Hourly urine outputs, though important, do not provide a comprehensive picture of fluid balance as they do not consider fluid intake, insensible losses, or other sources of fluid loss.

5. 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.
