Nursing Elites

1. A client on mechanical ventilation is experiencing high-pressure alarms. What action should the nurse implement first?

• A. Check the client's oxygen saturation.
• B. Assess the client's endotracheal tube for obstruction.
• C. Reposition the client to relieve pressure.
• D. Suction the client's airway.

Correct answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.

2. The nurse is administering an intradermal injection for a tuberculosis skin test. Which technique should the nurse use?

• A. Use a 25-gauge needle at a 90-degree angle
• B. Use a 27-gauge needle at a 15-degree angle
• C. Use a 22-gauge needle at a 45-degree angle
• D. Use a 20-gauge needle at a 90-degree angle

Correct answer: B

Rationale: An intradermal injection for a tuberculosis skin test should be administered using a 27-gauge needle at a 15-degree angle. This technique ensures that the medication is delivered into the dermis layer of the skin. Choice A is incorrect because a 25-gauge needle is too large for an intradermal injection. Choice C is incorrect as a 22-gauge needle is also too large and the angle is too steep for an intradermal injection. Choice D is incorrect as a 20-gauge needle is too large for an intradermal injection, and a 90-degree angle would not deliver the medication accurately into the dermis.

3. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?

• A. Short half-life
• B. High therapeutic index
• C. Highly protein-bound
• D. Low bioavailability

Correct answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

4. A client with cirrhosis is receiving lactulose. What is the most important assessment for the nurse to monitor?

• A. Monitor the client's ammonia levels.
• B. Monitor the client's blood glucose level.
• C. Monitor the client's potassium levels.
• D. Monitor the client's level of consciousness.

Correct answer: D

Rationale: The correct answer is to monitor the client's level of consciousness. Lactulose is used to reduce ammonia levels in hepatic encephalopathy. Monitoring the level of consciousness helps assess the effectiveness of lactulose therapy in improving the client's condition. Monitoring ammonia levels (choice A) is important, but assessing the client's response to therapy through their level of consciousness is more crucial. Blood glucose levels (choice B) and potassium levels (choice C) are not directly related to lactulose therapy for cirrhosis and hepatic encephalopathy.

5. A client with a history of closed head injury has a radial artery catheter in place and complains of numbness and pain distal to the insertion site. What action should the nurse take?

• A. Monitor the site for further complications.
• B. Promptly remove the catheter from the radial artery.
• C. Elevate the client’s arm above the heart.
• D. Notify the healthcare provider and prepare for surgery.

Correct answer: B

Rationale: A weak pulse and numbness distal to a radial artery catheter may indicate occlusion or damage to the artery, and immediate removal of the catheter is necessary to prevent complications. Therefore, promptly removing the catheter from the radial artery (Choice B) is the correct action. Monitoring the site (Choice A) would delay necessary intervention, elevating the client's arm (Choice C) may not address the underlying issue, and notifying the healthcare provider for surgery (Choice D) without removing the catheter promptly could lead to further complications.
