Nursing Elites

1. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:

• A. Compensated metabolic acidosis
• B. Compensated respiratory alkalosis
• C. Uncompensated metabolic alkalosis
• D. Uncompensated respiratory acidosis

Correct answer: B

Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.

2. A nurse is conducting an assessment of a client who underwent thoracentesis of the right side of the chest 3 hours ago. Which findings does the nurse report to the physician? Select all that apply.

• A. Unequal chest expansion
• B. Pulse rate of 82 beats/min
• C. Respiratory rate of 22 breaths/min
• D. Diminished breath sounds in the right lung

Correct answer: A

Rationale: After thoracentesis, the nurse should assess the client for signs of pneumothorax, which include increased respiratory rate, dyspnea, retractions, unequal chest expansion, diminished breath sounds, and cyanosis. Unequal chest expansion is a key sign of pneumothorax due to the accumulation of air in the pleural space, causing the affected lung to collapse partially. Pulse rate and respiratory rate within normal ranges, like in choices B and C, are not the priority findings to report in this situation. Diminished breath sounds in the right lung could be expected after thoracentesis and may not necessarily indicate a complication like pneumothorax, making choice D less urgent to report.

3. The client with peripheral artery disease has been prescribed clopidogrel (Plavix). The nurse understands that more teaching is necessary when the client states which of the following?

• A. I should not be surprised if I bruise more easily or if my gums bleed a little when brushing my teeth.
• B. It is important to take this medicine with food to enhance its effectiveness and minimize stomach upset.
• C. I should stop taking Plavix if it makes me feel weak and dizzy.
• D. The doctor prescribed this medicine to make my platelets less likely to stick together and help prevent clots from forming.

Correct answer: C

Rationale: The correct answer is C. Weakness, dizziness, and headache are common adverse effects of Plavix and should be reported. It is essential to consult a physician before stopping Plavix as it plays a crucial role in preventing platelets from sticking together and forming clots. Choices A, B, and D are incorrect. Choice A is a common side effect of Plavix and does not indicate a need for further teaching. Choice B is incorrect because taking Plavix with or without food can affect its absorption and effectiveness. Choice D correctly explains the purpose of prescribing Plavix to prevent clot formation.

4. A client has been taking oral corticosteroids for the past five days because of seasonal allergies. Which assessment finding is of most concern to the nurse?

• A. White blood count of 10,000/mm³.
• B. Serum glucose of 115 mg/dL.
• C. Purulent sputum.
• D. Excessive hunger.

Correct answer: C

Rationale: The correct answer is C: Purulent sputum. Corticosteroids can suppress the immune system, increasing the risk of infections. Purulent sputum suggests a possible respiratory infection, which can rapidly progress and lead to complications, making it the most concerning finding. Choice A, a white blood count of 10,000/mm³, is within the normal range and not typically a cause for immediate concern. Choice B, a serum glucose level of 115 mg/dL, is also normal and not directly related to corticosteroid use. Choice D, excessive hunger, is a common side effect of corticosteroids but is not as concerning as a sign of infection indicated by purulent sputum.

5. To help minimize the risk of postoperative respiratory complications after a hypophysectomy, during preoperative teaching, the nurse should instruct the client how to:

• A. Use incentive spirometry.
• B. Turn in bed.
• C. Take deep breaths.
• D. Cough.

Correct answer: C

Rationale: The correct answer is to instruct the client on how to take deep breaths. Deep breathing exercises are essential in preventing postoperative respiratory complications like atelectasis by promoting lung expansion. Using incentive spirometry is a more specific and advanced method of promoting deep breathing and lung expansion, making it a better choice than just turning in bed. While turning in bed may help with overall comfort and positioning, it is not as directly related to respiratory complications as deep breathing exercises. Coughing, although important for clearing secretions, is not as effective in preventing atelectasis as deep breathing exercises.
