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. Prior to a thoracentesis, what intervention should the nurse complete?

• A. Measure oxygen saturation before and after the procedure.
• B. Verify that the client has given informed consent.
• C. Explain the procedure briefly to the client and their family.
• D. Ensure informed consent has been obtained from the client.

Correct answer: D

Rationale: Before a thoracentesis procedure, it is crucial to ensure that the client has given informed consent. This process involves explaining the procedure, its risks, benefits, and alternatives to the client, and obtaining their signature on the consent form. Verifying informed consent is a vital legal and ethical step to protect the client's autonomy and ensure they have made an informed decision about the procedure.

3. A client had a stroke involving the right cerebral hemisphere. The nurse should monitor for which of the following findings?

• A. Poor impulse control
• B. Inability to discriminate words and letters
• C. Deficits in the right visual field
• D. Motor retardation

Correct answer: A

Rationale: A stroke affecting the right cerebral hemisphere can lead to poor impulse control due to the involvement of this area in regulating behavior and inhibiting impulses. Deficits in the right visual field are associated with stroke affecting the left cerebral hemisphere. Inability to discriminate words and letters may be seen in left cerebral hemisphere strokes. Motor retardation may be observed with strokes affecting motor areas in either hemisphere but is not the most specific finding related to a right cerebral hemisphere stroke.

4. A healthcare professional assesses a client's respiratory status. Which information is of highest priority for the healthcare professional to obtain?

• A. Average daily fluid intake
• B. Neck circumference
• C. Height & weight
• D. Occupation & hobbies

Correct answer: D

Rationale: Obtaining information about a client's occupation and hobbies is crucial when assessing respiratory status as many respiratory problems can result from chronic exposure to inhalation irritants related to these activities. Understanding the client's potential exposure can help the healthcare professional identify risk factors and provide appropriate interventions to promote respiratory health.

5. The client with a chest tube after a coronary artery bypass graft has significantly slowed drainage. What action is most important for the nurse to take?

• A. Increase the setting on the suction.
• B. Notify the provider immediately.
• C. Re-position the chest tube.
• D. Take the tubing apart to assess for clots.

Correct answer: B

Rationale: If the drainage from the chest tube decreases significantly, it may indicate a blockage by a clot, potentially leading to cardiac tamponade. The nurse's priority action should be to notify the healthcare provider immediately for further evaluation and intervention. Increasing suction, re-positioning the chest tube, or disassembling the tubing independently are not appropriate actions without healthcare provider guidance in this situation.
