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. 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.

3. 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.

4. The nurse assesses a client who has a nasal cannula delivering oxygen at 2 L/min. To assess for skin damage related to the cannula, which areas should the nurse observe? (Select all that apply).

• A. Tops of the ears
• B. Bridge of the nose
• C. Around the nostrils
• D. Over the cheeks

Correct answer: C

Rationale: The correct answer is C: 'Around the nostrils.' Constant pressure from the tubing may create skin damage to the areas of skin and bony prominences the nasal cannula will be resting on, including around the nostrils. Choice A, 'Tops of the ears,' is incorrect as the cannula does not rest on the ears. Choice B, 'Bridge of the nose,' is incorrect because the cannula typically rests under the nose. Choice D, 'Over the cheeks,' is also incorrect as the cannula does not typically rest on the cheeks.

5. A male client with unstable angina needs a cardiac catheterization. So the healthcare provider explains the risks and benefits of the procedure and then leaves to set up for the procedure. When the nurse presents the consent form for signature, the client hesitates and asks how the wires will keep his heart going. Which action should the nurse take?

• A. Answer the client's specific questions with a short, understandable explanation
• B. Postpone the procedure until the client understands the risks and benefits
• C. Call the client's next of kin and ask them to provide verbal consent
• D. Page the healthcare provider to return and provide additional explanation

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to page the healthcare provider to return and provide additional explanation. It is crucial for the client to have a clear understanding of the procedure, including its risks and benefits, before signing the consent form. While the nurse can provide general information, the detailed explanation of how the procedure works and its effects should come from the healthcare provider who will perform the procedure. Postponing the procedure until the client understands is appropriate, but the immediate need is to clarify the client's concerns with the healthcare provider. Calling the client's next of kin for verbal consent is not the correct course of action as the client is present and able to provide consent after receiving adequate information.
