Nursing Elites

1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

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

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. A client developed fat embolism syndrome (FES) following a fracture. Which of the following laboratory findings should the nurse expect?

• A. Decreased serum calcium level
• B. Decreased level of serum lipids
• C. Decreased erythrocyte sedimentation rate (ESR)
• D. Increased platelet count

Correct answer: A

Rationale: In fat embolism syndrome (FES), fat globules enter the bloodstream and can lead to various complications, including a decrease in serum calcium levels. This occurs due to the formation of fat emboli in the vessels, which can interfere with calcium metabolism. Therefore, a decreased serum calcium level is an expected laboratory finding in a client with fat embolism syndrome.

3. A client has a pulmonary embolism & is started on oxygen. The student nurse asks why the client's oxygen saturation has not significantly improved. What response by the nurse is best?

• A. Breathing so rapidly interferes with oxygenation.
• B. Maybe the client has respiratory distress syndrome.
• C. The blood clot interferes with perfusion in the lungs.
• D. The client needs immediate intubation & mechanical ventilation.

Correct answer: C

Rationale: A large blood clot in the lungs will significantly impair gas exchange & oxygenation. Unless the clot is dissolved, this process will continue unabated.

4. A client had an inferior wall myocardial infarction (MI). The nurse notes the client's cardiac rhythm as shown below. What action by the nurse is most important?

• A. Assess the client's blood pressure and level of consciousness.
• B. Call the health care provider or the Rapid Response Team.
• C. Obtain a permit for an emergency temporary pacemaker insertion.
• D. Prepare to administer antidysrhythmic medication.

Correct answer: A

Rationale: The ECG strip shows sinus bradycardia, which is common in clients with an inferior wall MI. This rhythm can lead to decreased perfusion due to bradycardia and blocks. The most crucial initial action for the nurse is to assess the client's hemodynamic status, including blood pressure and level of consciousness. This assessment will help determine the immediate needs of the client. Calling the health care provider or the Rapid Response Team, obtaining a permit for a pacemaker insertion, or preparing to administer antidysrhythmic medication may be necessary based on the assessment findings, but the priority is to evaluate the client's current condition first.

5. A nurse collaborates with a respiratory therapist to complete pulmonary function tests (PFTs) for a client. Which statements should the nurse include in communications with the respiratory therapist prior to the tests? (Select all that apply)

• A. I held the client's morning bronchodilator medication.
• B. The client is ready to go down to radiology for this examination.
• C. Physical therapy states the client can run on a treadmill.
• D. I advised the client not to smoke for 6 hours prior to the test.

Correct answer: B

Rationale: Communication between the nurse and respiratory therapist is crucial before pulmonary function tests (PFTs). It is important to inform the respiratory therapist that the client is ready for the examination. The nurse should not administer bronchodilator medication before the test as it may affect the results, and the client should not smoke for 6 to 8 hours prior to the test to ensure accurate results. Additionally, PFTs do not involve running on a treadmill; instead, the client may be required to perform specific breathing maneuvers as instructed by the respiratory therapist.
