Nursing Elites

1. A healthcare professional is monitoring the respiratory status of a client who has just undergone surgery and is wearing a pulse oximeter. Which of the following coexisting problems is cause for the healthcare professional to suspect that the oxygen saturation readings are not entirely accurate?

• A. Infection
• B. Hypertension
• C. Low blood pressure
• D. Loss of cough reflex

Correct answer: C

Rationale: Low blood pressure (hypotension), shock, and the use of peripheral vasoconstricting medications can lead to inaccurate pulse oximetry readings due to impaired peripheral perfusion. Hypertension and infection are not typically associated with inaccurate pulse oximetry readings, while the loss of cough reflex does not directly affect oxygen saturation readings.

2. A client with a chest tube attached to a closed drainage system has undergone a chest x-ray, which revealed that the affected lung is fully reexpanded. The nurse anticipates that the next assessment of the chest tube system will reveal:

• A. No fluctuation in the water seal chamber
• B. Continuous bubbling in the water seal chamber
• C. Increased drainage in the collection chamber
• D. Continuous gentle suction in the suction control chamber

Correct answer: A

Rationale: When the client's lung is fully reexpanded, the chest tube drainage system will no longer be actively draining, and there will be no fluctuation in the water seal chamber. Option B, continuous bubbling in the water seal chamber, indicates an air leak in the system, which is not expected when the lung is fully expanded. Option C, increased drainage in the collection chamber, would not be expected when the lung is reexpanded as there should be minimal to no drainage. Option D, continuous gentle suction in the suction control chamber, would not be appropriate when the lung is fully reexpanded and the chest tube is typically on a water seal system at this point to promote reexpansion and prevent air from entering the pleural space.

3. A client who has undergone abdominal surgery calls the nurse and reports that she just felt 'something give way' in the abdominal incision. The nurse checks the incision and notes the presence of wound dehiscence. The nurse immediately:

• A. Contacts the physician
• B. Documents the findings
• C. Places the client in a supine position with the legs flat
• D. Covers the abdominal wound with a sterile dressing moistened with sterile saline solution

Correct answer: D

Rationale: In the scenario described, the presence of wound dehiscence indicates a separation of the layers of the surgical incision. The immediate priority for the nurse is to cover the abdominal wound with a sterile dressing moistened with sterile saline solution. This helps to protect the wound from contamination and promotes a moist environment conducive to healing. Contacting the physician (Choice A) is important, but the initial action should be to address the wound. Documenting the findings (Choice B) is necessary but not the immediate priority. Placing the client in a supine position with the legs flat (Choice C) is not indicated in this situation as wound dehiscence requires wound care intervention.

4. A nurse cares for a client with diabetes mellitus who is prescribed metformin (Glucophage) and is scheduled for an intravenous urography. Which action should the nurse take first?

• A. Contact the provider and recommend discontinuing the metformin.
• B. Keep the client NPO for at least 6 hours prior to the examination.
• C. Check the client’s capillary artery blood glucose and administer prescribed insulin.
• D. Administer intravenous fluids to dilute and increase the excretion of dye.

Correct answer: A

Rationale: Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye. This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established. The client’s health care provider needs to provide alternative therapy for the client until the metformin can be resumed. Keeping the client NPO, checking the client’s blood glucose, and administering intravenous fluids should be part of the client’s plan of care, but are not the priority, as the examination should not occur while the client is still taking metformin.

5. What types of medications should the healthcare provider expect to administer to a client during an acute respiratory distress episode?

• A. Vasodilators and hormones.
• B. Analgesics and sedatives.
• C. Anticoagulants and expectorants.
• D. Bronchodilators and steroids.

Correct answer: D

Rationale: During an acute respiratory distress episode, the priority is to widen air passages, increase air space, and reduce alveolar membrane inflammation. Therefore, the client would likely require bronchodilators to open up the airways and steroids to reduce inflammation. Vasodilators and hormones (Choice A) are not typically indicated in this situation. Analgesics and sedatives (Choice B) may be used for pain management and anxiety but are not primary treatments for respiratory distress. Anticoagulants and expectorants (Choice C) are not the main medications used during an acute respiratory distress episode and may not address the immediate needs of the client.
