Nursing Elites

1. A nurse is caring for a client who has heart failure and is receiving digoxin. Which of the following findings should the nurse identify as a sign of digoxin toxicity?

• A. Bradycardia
• B. Tachycardia
• C. Hypotension
• D. Increased appetite

Correct answer: A

Rationale: Corrected Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin, a medication used to treat heart failure, works by slowing down the heart rate and increasing the force of heart contractions. Excessive levels of digoxin can lead to toxicity, causing bradycardia (slow heart rate), among other symptoms. Tachycardia (fast heart rate) and hypotension (low blood pressure) are not typically associated with digoxin toxicity. Increased appetite is not a recognized sign of digoxin toxicity; instead, gastrointestinal symptoms like nausea, vomiting, and anorexia are more common.

2. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

3. A nurse is caring for a client following an acute myocardial infarction. The client is concerned that providing self-care will be difficult due to extreme fatigue. Which of the following strategies should the nurse implement to promote the client's independence?

• A. Request an occupational therapy consult to determine the need for assistive devices
• B. Assign assistive personnel to perform self-care tasks for the client
• C. Instruct the client to focus on gradually resuming self-care tasks
• D. Ask the client if a family member is available to assist with his care

Correct answer: C

Rationale: Instructing the client to focus on gradually resuming self-care tasks is the most appropriate strategy to promote independence following an acute myocardial infarction. This approach allows the client to regain confidence and control over their self-care activities without feeling overwhelmed. Requesting an occupational therapy consult (Choice A) may be beneficial but is not the immediate solution to promote independence. Assigning assistive personnel (Choice B) to perform tasks for the client does not encourage independence. Asking if a family member is available for assistance (Choice D) does not directly promote the client's independence.

4. A nurse is reviewing the medical record of a client who is receiving warfarin for atrial fibrillation. Which of the following findings should the nurse report to the provider?

• A. International normalized ratio (INR) of 2.5
• B. Platelet count of 180,000/mm³
• C. Prothrombin time (PT) of 12 seconds
• D. Partial thromboplastin time (PTT) of 30 seconds

Correct answer: C

Rationale: A prothrombin time (PT) of 12 seconds is below the therapeutic range for warfarin and indicates a need for dosage adjustment. The correct answer is C. A normal International normalized ratio (INR) for a client on warfarin therapy is usually between 2.0 to 3.0; therefore, an INR of 2.5 is within the expected range. A platelet count of 180,000/mm³ is within the normal range (150,000 to 450,000/mm³) and does not require immediate reporting. A partial thromboplastin time (PTT) of 30 seconds is also within the normal range (25-35 seconds) and does not indicate a need for urgent action.

5. A client who is immobile needs interventions to prevent contractures. Which of the following interventions is appropriate?

• A. Aligning a trochanter wedge between the client's legs.
• B. Placing a towel roll under the client's neck.
• C. Applying an orthotic to the client's foot.
• D. Positioning a pillow under the client's knees.

Correct answer: C

Rationale: Applying an orthotic to the client's foot is the appropriate intervention to prevent contractures in an immobile client. An orthotic helps maintain proper alignment and prevents the development of contractures by keeping the foot in the correct position. Choices A, B, and D are incorrect because a trochanter wedge, towel roll under the neck, and pillow under the knees are not specific interventions for preventing contractures in an immobile client.
