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 with a history of gastrointestinal bleeding is taking warfarin (Coumadin). Which instruction should the nurse include in the teaching plan?

• A. Avoid eating foods high in vitamin K.
• B. Take aspirin for pain relief.
• C. Report any signs of bruising or bleeding to your healthcare provider.
• D. Limit fluid intake to 2 liters per day.

Correct answer: C

Rationale: The correct instruction for a client taking warfarin, an anticoagulant, is to report any signs of bruising or bleeding to the healthcare provider promptly. This is crucial as these symptoms may indicate over-anticoagulation, which can lead to serious complications. Monitoring for signs of bleeding is essential to adjust the medication dosage or take appropriate measures to ensure the client's safety.

3. A client who is intubated and has an intra-aortic balloon pump is restless and agitated. What action should the nurse perform first for comfort?

• A. Allow family members to remain at the bedside.
• B. Ask the family if the client would like a fan in the room.
• C. Keep the television tuned to the client's favorite channel.
• D. Speak loudly to the client in case of hearing problems.

Correct answer: A

Rationale: Allowing the family to remain at the bedside can help calm the client with familiar voices and presence, potentially reducing restlessness and agitation. Introducing a fan may not be the priority as it can spread germs through air movement. Keeping the television on all the time may not promote rest and recovery. Speaking loudly is not advisable as it may further agitate the client. Therefore, the initial action of allowing family members to stay is most likely to provide comfort and reassurance to the client.

4. A nurse is assessing a client for a suspected anaphylactic reaction following a CT scan with contrast media. For which of the following client findings should the nurse intervene first?

• A. Urticaria
• B. Stridor
• C. Vomiting
• D. Hypotension

Correct answer: B

Rationale:

5. A client with diabetes is experiencing symptoms of hypoglycemia. What should the nurse administer first?

• A. 10 units of regular insulin subcutaneously
• B. 50 mL of 50% dextrose solution intravenously
• C. 1 mg of glucagon intramuscularly
• D. 15-20 grams of fast-acting carbohydrate orally

Correct answer: D

Rationale: The correct first intervention for a client experiencing hypoglycemia is administering 15-20 grams of fast-acting carbohydrate orally. If the client is conscious and able to swallow, providing quick-acting carbohydrates helps raise blood glucose levels rapidly and effectively. This approach is preferred over other options like administering insulin, dextrose solution intravenously, or glucagon, which are not the initial interventions for hypoglycemia.
