Nursing Elites

1. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

2. A client with a history of alcoholism is admitted with confusion, ataxia, and nystagmus. Which nursing intervention is a priority for this client?

• A. Monitor for signs of alcohol withdrawal.
• B. Administer thiamine as prescribed.
• C. Provide a quiet environment to reduce confusion.
• D. Initiate fall precautions.

Correct answer: B

Rationale: The correct answer is B: Administer thiamine as prescribed. Administering thiamine is crucial in clients with a history of alcoholism to prevent Wernicke's encephalopathy, which is characterized by confusion, ataxia, and nystagmus. Monitoring for signs of alcohol withdrawal (choice A) is important but not the priority. Providing a quiet environment (choice C) and initiating fall precautions (choice D) are important interventions, but administering thiamine takes precedence due to the risk of Wernicke's encephalopathy.

3. While taking vital signs, a critically ill male client grabs the nurse's hand and asks the nurse not to leave. What action is best for the nurse to take?

• A. Pull up a chair and sit beside the client's bed.
• B. Reassure the client that you will return shortly.
• C. Ask another nurse to stay with the client.
• D. Continue taking vital signs and then leave the room.

Correct answer: A

Rationale: The best action for the nurse to take in this situation is to pull up a chair and sit beside the client's bed. By doing so, the nurse can provide emotional support and comfort to the critically ill patient who is feeling vulnerable. Sitting with the client also shows empathy and a willingness to listen to the client's needs. Reassuring the client that the nurse will return shortly (Choice B) may not address the immediate need for emotional support. Asking another nurse to stay with the client (Choice C) may not establish the same level of connection and comfort as sitting with the client personally. Continuing to take vital signs and then leaving the room (Choice D) disregards the client's emotional needs in that moment.

4. A confused, older client with Alzheimer's disease becomes incontinent of urine when attempting to find the bathroom. Which action should the nurse implement?

• A. Assist the client to a bedside commode every two hours
• B. Insert an indwelling catheter
• C. Use adult diapers to manage incontinence
• D. Restrict fluids in the evening

Correct answer: A

Rationale: The correct action for the nurse to implement is to assist the client to a bedside commode every two hours. This approach, known as scheduled toileting, is essential in managing incontinence in clients with cognitive impairments like Alzheimer's disease. By providing regular assistance to the client to use the commode, the nurse can help maintain continence and reduce accidents. Inserting an indwelling catheter (Choice B) should be avoided if possible to prevent the risk of urinary tract infections. Using adult diapers (Choice C) should be considered a last resort and not the initial intervention. Restricting fluids in the evening (Choice D) is not appropriate as it may lead to dehydration and other complications.

5. The nurse is caring for a client who is postoperative following a thyroidectomy. Which laboratory value should be monitored closely?

• A. Serum calcium of 8.5 mg/dL
• B. Serum sodium of 136 mEq/L
• C. Serum potassium of 3.0 mEq/L
• D. Serum chloride of 102 mEq/L

Correct answer: C

Rationale: A serum potassium level of 3.0 mEq/L should be monitored closely in a client who is postoperative following a thyroidectomy to detect any electrolyte imbalances. After a thyroidectomy, there is a risk of hypokalemia due to the effects of anesthesia, stress response, and the surgical procedure itself. Monitoring serum potassium levels is crucial as hypokalemia can lead to cardiac arrhythmias and muscle weakness. Serum calcium, sodium, and chloride levels are important but not the primary focus following a thyroidectomy, making them incorrect choices.
