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 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.

3. A client with chronic obstructive pulmonary disease is receiving dietary teaching from a nurse. Which of the following instructions should the nurse include?

• A. Eat 3 balanced meals each day.
• B. Limit fluid intake with meals.
• C. Reduce sodium intake.
• D. Take a bronchodilator 1 hour before eating.

Correct answer: B

Rationale: In clients with chronic obstructive pulmonary disease, limiting fluid intake with meals can help reduce the risk of bloating and feeling too full, which can make breathing more difficult due to increased pressure on the diaphragm. It is important to encourage a balanced diet with appropriate fluid intake between meals to maintain hydration and proper nutrition. Options A, C, and D are not specifically related to dietary recommendations for clients with chronic obstructive pulmonary disease.

4. A client is scheduled for a colonoscopy and receiving education from a healthcare provider. Which statement by the client indicates a need for further teaching?

• A. I can have clear liquids up to 2 hours before the procedure.
• B. I need to take a laxative the night before the procedure.
• C. I will be sedated during the procedure.
• D. I should avoid eating solid foods for 24 hours before the procedure.

Correct answer: D

Rationale: The correct answer is D because clients are typically instructed to avoid solid foods for 12-24 hours before a colonoscopy, not a full 24 hours. This statement indicates a need for further teaching to ensure the client follows the correct dietary instructions for the procedure.

5. 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.
