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. A patient is receiving a 3% saline continuous IV infusion for hyponatremia. Which assessment data will require the most rapid response by the nurse?
- A. The patient’s radial pulse is 105 beats/minute.
- B. There is sediment and blood in the patient’s urine.
- C. The blood pressure increases from 120/80 to 142/94.
- D. There are crackles audible throughout both lung fields.
Correct answer: D
Rationale: Crackles throughout both lungs suggest that the patient may be experiencing pulmonary edema, a life-threatening adverse effect of hypertonic solutions. The increased pulse rate and blood pressure and the presence of sediment and blood in the urine should also be reported, but they are not as immediately dangerous as the presence of fluid in the alveoli, which compromises gas exchange and can lead to respiratory failure.
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. The nurse is caring for a patient with a massive burn injury and possible hypovolemia. Which assessment data will be of most concern to the nurse?
- A. Blood pressure is 90/40 mm Hg.
- B. Urine output is 30 mL over the last hour.
- C. Oral fluid intake is 100 mL over the last 8 hours.
- D. There is prolonged skin tenting over the sternum.
Correct answer: A
Rationale: The correct answer is A: "Blood pressure is 90/40 mm Hg." A low blood pressure reading of 90/40 mm Hg indicates that the patient may be developing hypovolemic shock due to intravascular fluid loss from the burn injury. This finding is of utmost concern as it suggests systemic hypoperfusion, requiring immediate intervention to prevent complications. Choices B, C, and D also indicate signs of dehydration and the need to increase fluid intake; however, they are not as urgent as addressing the hypotension and potential shock presented in choice A.
5. A newly admitted patient is diagnosed with hyponatremia. When making room assignments, the charge nurse should take which action?
- A. Assign the patient to a room near the nurse’s station.
- B. Place the patient in a room nearest to the water fountain.
- C. Place the patient on telemetry to monitor for peaked T waves.
- D. Assign the patient to a semi-private room and place an order for a low-salt diet.
Correct answer: A
Rationale: The correct answer is A. The patient should be placed near the nurse’s station if confused to allow close monitoring by the staff. To help improve serum sodium levels, water intake is restricted, so a patient with hyponatremia should not be placed near a water fountain. Peaked T waves are a sign of hyperkalemia, not hyponatremia, so telemetry for this purpose is unnecessary. Placing a confused patient in a semi-private room could be disruptive to the other patient. Additionally, the patient needs sodium replacement, not a low-salt diet.
