Nursing Elites

1. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

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

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.

2. The nurse is preparing an older adult for discharge following cataract extraction. What is the most important instruction?

• A. Avoid straining, bending, or lifting heavy objects.
• B. Limit exposure to sunlight for the first 2 weeks.
• C. Use direct lighting when reading for 6 weeks.
• D. Irrigate the conjunctiva with saline before applying ointment.

Correct answer: A

Rationale: The most important instruction for a patient following cataract extraction is to avoid straining, bending, or lifting heavy objects. These activities can increase intraocular pressure and potentially lead to complications such as bleeding or dislocation of the intraocular lens. Choices B, C, and D are not as critical in the immediate post-operative period. Limiting sunlight exposure and using direct lighting when reading are important but not as crucial as avoiding activities that can increase intraocular pressure. Irrigating the conjunctiva with saline before applying ointment is not a standard post-cataract surgery instruction.

3. An older adult client with heart failure (HF) and hypertension (HTN) is receiving atenolol, furosemide, and enalapril. Which assessments are essential to evaluate the effectiveness of the medications?

• A. Bowel sounds and daily weight.
• B. Daily weight and blood pressure.
• C. Heart sounds and range of motion.
• D. Monitor for evidence of hypokalemia.

Correct answer: B

Rationale: Monitoring daily weight and blood pressure is crucial to assess the effectiveness of diuretics (furosemide) and antihypertensives (atenolol, enalapril) in managing heart failure and hypertension. Changes in weight indicate fluid status, while blood pressure readings reflect the control of hypertension. Assessing bowel sounds and range of motion are important but not directly related to evaluating the effectiveness of these specific medications in this scenario. Monitoring for hypokalemia is important due to furosemide's potential side effect, but it is not the primary assessment to evaluate medication effectiveness.

4. An adult client with a broken femur reports muscle spasms. What action should the nurse implement while awaiting surgery?

• A. Check the client's most recent electrolyte levels.
• B. Administer a PRN dose of muscle relaxant.
• C. Reduce the weight on the traction device.
• D. Encourage oral fluid intake to relieve muscle tension.

Correct answer: D

Rationale: The correct action for the nurse to implement while awaiting surgery for a client with muscle spasms due to a broken femur is to encourage oral fluid intake to relieve muscle tension. Dehydration can exacerbate muscle spasms, so increasing fluid intake can help alleviate them. Checking electrolyte levels may not directly address muscle spasms in this situation. Administering a muscle relaxant should be based on a healthcare provider's prescription, and traction weight adjustments should only be made by the provider overseeing the client's care.

5. A client with hyperthyroidism is admitted to the postoperative unit after a subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?

• A. Blood glucose 90 mg/dL
• B. Sodium 138 mEq/L
• C. Total calcium 5.0 mg/dL
• D. Potassium 4.2 mEq/L

Correct answer: C

Rationale: A total calcium level of 5.0 mg/dL is critically low and indicates possible hypocalcemia, a common complication after thyroid surgery. This condition can lead to tetany and requires immediate intervention. Blood glucose within normal range, sodium, and potassium levels are not indicative of an immediate postoperative complication like hypocalcemia in this case.
