Nursing Elites

1. During the assessment, a client receiving a continuous infusion of heparin for deep vein thrombosis (DVT) is found to have a nosebleed. Which finding requires immediate action?

• A. The client's activated partial thromboplastin time (aPTT) is 70 seconds.
• B. The client has developed a nosebleed.
• C. The client's blood pressure is 150/90 mm Hg.
• D. The client reports feeling lightheaded.

Correct answer: B

Rationale: A nosebleed (B) in a client receiving heparin is a sign of heparin toxicity and requires immediate action. It indicates that the client is at risk of excessive bleeding. While a prolonged aPTT of 70 seconds (A) is worth monitoring, active bleeding takes precedence. Elevated blood pressure (C) and lightheadedness (D) are potential side effects of heparin but are not as urgently concerning as active bleeding.

2. What is the most important action for the nurse to take when caring for a client with a spinal cord injury experiencing autonomic dysreflexia?

• A. Elevate the head of the bed to 45 degrees.
• B. Monitor the client's respiratory rate.
• C. Administer an antihypertensive medication.
• D. Assess the client's blood glucose level.

Correct answer: A

Rationale: In a client with autonomic dysreflexia, the most critical action is to elevate the head of the bed to 45 degrees (A). This positioning helps reduce blood pressure, which is essential in managing autonomic dysreflexia. Monitoring the client's respiratory rate (B) is important for overall assessment but not the priority in this situation. Administering an antihypertensive medication (C) without addressing the positioning issue first can lead to further complications. Assessing the client's blood glucose level (D) is not directly related to autonomic dysreflexia and is not the initial priority in this scenario.

3. A client with a history of myocardial infarction (MI) is admitted with chest pain. Which laboratory test should the nurse expect to be ordered to determine if the client is experiencing another MI?

• A. Troponin
• B. Myoglobin
• C. CK-MB
• D. C-reactive protein

Correct answer: A

Rationale: Troponin is the most specific and sensitive laboratory test for detecting myocardial infarction (MI). It is released when there is damage to the heart muscle, making it a valuable marker for diagnosing another MI. Myoglobin and CK-MB can also be elevated in MI, but troponin is preferred due to its higher specificity. C-reactive protein is a marker of inflammation and not specific to MI.

4. The health care provider has changed a client's prescription from the PO to the IV route of administration. The nurse should anticipate which change in the pharmacokinetic properties of the medication?

• A. The client will experience increased tolerance to the drug's effects and may need a higher dose.
• B. The onset of action of the drug will occur more rapidly, resulting in a more rapid effect.
• C. The medication will be more highly protein-bound, increasing the duration of action.
• D. The therapeutic index will be increased, placing the client at greater risk for toxicity.

Correct answer: B

Rationale: When a medication is administered via the IV route, the absorptive process is bypassed, leading to a more rapid onset of action. This results in a faster effect of the drug. Choice A is incorrect because changing the route of administration does not necessarily lead to increased tolerance or the need for a higher dose. Choice C is incorrect as changing the route of administration does not directly affect the protein binding of a medication. Choice D is incorrect because increasing the therapeutic index would actually reduce the risk of toxicity, not increase it.

5. What is the most important instruction for the nurse to provide to a 65-year-old client who attends an adult daycare program, is wheelchair-mobile, and has redness in the sacral area?

• A. Take a vitamin supplement tablet once a day.
• B. Change positions in the chair at least every hour.
• C. Increase daily intake of water or other oral fluids.
• D. Purchase a newer model wheelchair.

Correct answer: B

Rationale: For a client with redness in the sacral area, the most critical instruction is to change positions in the chair at least every hour. This is crucial to prevent pressure ulcers, which can develop due to prolonged pressure on the skin and underlying tissues. Regular position changes help relieve pressure on vulnerable areas, promoting circulation and reducing the risk of skin breakdown and pressure ulcer formation.
