Nursing Elites

1. A patient who has small cell carcinoma of the lung develops syndrome of inappropriate antidiuretic hormone (SIADH). The nurse should notify the healthcare provider about which assessment finding?

• A. Reported weight gain
• B. Serum hematocrit of 42%
• C. Serum sodium level of 120 mEq/L
• D. Total urinary output of 280 mL during the past 8 hours

Correct answer: C

Rationale: The correct answer is C, a serum sodium level of 120 mEq/L. Hyponatremia is the most important finding to report in SIADH. SIADH causes water retention and a decrease in serum sodium levels. Hyponatremia can lead to confusion and other central nervous system effects and requires treatment. Adequate kidney function is indicated by a urinary output of at least 30 mL/hr. A hematocrit level of 42% is normal. Weight gain is expected due to water retention in SIADH.

2. 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.

3. While changing a client's post-operative dressing, the nurse observes a red and swollen wound with a moderate amount of yellow and green drainage and a foul odor. Given there is a positive MRSA, which is the most important action for the nurse to take?

• A. Force oral fluids
• B. Request a nutrition consult
• C. Initiate contact precautions
• D. Limit visitors to immediate family only

Correct answer: C

Rationale: The most important action for the nurse to take when a client has a positive MRSA and presents with a wound showing signs of infection is to initiate contact precautions. MRSA is highly contagious and placing the patient on contact precautions helps prevent the spread of the bacteria to others in the healthcare setting. (A) Forcing oral fluids will not directly address the MRSA infection. (B) Requesting a nutrition consult is not the priority in this situation. (D) Limiting visitors to immediate family only is not necessary as MRSA precautions are primarily focused on healthcare workers and close contacts who provide direct care.

4. An older patient receiving iso-osmolar continuous tube feedings develops restlessness, agitation, and weakness. Which laboratory result should the nurse report to the health care provider immediately?

• A. K+ 3.4 mEq/L (3.4 mmol/L)
• B. Ca+2 7.8 mg/dL (1.95 mmol/L)
• C. Na+ 154 mEq/L (154 mmol/L)
• D. PO4-3 4.8 mg/dL (1.55 mmol/L)

Correct answer: C

Rationale: The correct answer is C. The elevated serum sodium level (154 mEq/L) is consistent with the patient's neurologic symptoms of restlessness, agitation, and weakness, indicating a need for immediate action to prevent complications like seizures. The potassium level (3.4 mEq/L) and calcium level (7.8 mg/dL) are slightly off from normal but do not require immediate action. The phosphate level (4.8 mg/dL) is normal and not related to the symptoms presented by the patient.

5. A nurse is assessing a newly admitted patient with chronic heart failure who forgot to take prescribed medications and seems confused. The patient complains of "just blowing up" and has peripheral edema and shortness of breath. Which assessment should the nurse complete first?

• A. Skin turgor
• B. Heart sounds
• C. Mental status
• D. Capillary refill

Correct answer: C

Rationale: Increases in extracellular fluid (ECF) can lead to swelling of cells in the central nervous system, initially causing confusion, which may progress to coma or seizures. Although skin turgor, capillary refill, and heart sounds also may be affected by increases in ECF, these are signs that do not have as immediate impact on patient outcomes as cerebral edema.
