Nursing Elites

1. A patient who is lethargic and exhibits deep, rapid respirations has the following arterial blood gas (ABG) results: pH 7.32, PaO2 88 mm Hg, PaCO2 37 mm Hg, and HCO3 16 mEq/L. How should the nurse interpret these results?

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

Correct answer: A

Rationale: The patient's pH is below the normal range (7.35-7.45), and the HCO3 is also below the normal range (22-26 mEq/L), indicating an acidic environment, which is consistent with metabolic acidosis. The ABGs provided do not support respiratory acidosis or alkalosis, as the PaCO2 is within the normal range (35-45 mm Hg) despite the patient's deep, rapid respirations. Therefore, the correct interpretation is metabolic acidosis.

2. What is the first action the nurse should take when a patient complains of acute chest pain and dyspnea soon after insertion of a centrally inserted IV catheter?

• A. Notify the health care provider.
• B. Offer reassurance to the patient.
• C. Auscultate the patient’s breath sounds
• D. Give the prescribed PRN morphine sulfate IV

Correct answer: C

Rationale: The correct first action for the nurse to take when a patient complains of acute chest pain and dyspnea after the insertion of a centrally inserted IV catheter is to auscultate the patient's breath sounds. This is important to assess for any potential complications such as embolism or pneumothorax, which can present with such symptoms. Auscultation can provide immediate information on the patient's respiratory status and guide further interventions. Notifying the health care provider, offering reassurance, or administering morphine should only be considered after assessing the patient's condition through auscultation.

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 is teaching the parent of a child newly diagnosed with a latex allergy. Which information by the parents indicates a need for further teaching?

• A. Rubber-free toys, such as wooden building blocks, are good choices for the child.
• B. Only foil balloons will be used for the child's birthday party.
• C. A diet of healthy fruits, such as bananas and kiwis, is best for the child.
• D. An epinephrine auto-injector will be on hand to treat allergic reactions.

Correct answer: C

Rationale: The correct answer is C. Bananas and kiwis are foods that can cross-react with latex allergy, indicating that the parents need further teaching on managing latex allergies. Choices A, B, and D are correct as rubber-free toys, using foil balloons, and having an epinephrine auto-injector are appropriate measures to prevent and manage allergic reactions in a child with a latex allergy.

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.
