Nursing Elites

1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. During a Weber test, what is an appropriate action for the nurse to take?

• A. Deliver a series of high-pitched sounds at random intervals.
• B. Place an activated tuning fork in the middle of the client's forehead.
• C. Hold an activated tuning fork against the client's mastoid process.
• D. Whisper a series of words softly into one ear.

Correct answer: B

Rationale: During a Weber test, the nurse should place an activated tuning fork in the middle of the client's forehead. This test is used to assess for lateralization of sound in a client with possible hearing issues. Choice A is incorrect because the Weber test does not involve delivering high-pitched sounds at random intervals. Choice C is incorrect as it describes the Rinne test, not the Weber test. Choice D is incorrect as whispering words into one ear is not part of the Weber test procedure.

3. A client scheduled for a hysterectomy has not yet signed the operative consent form. When the nurse approaches the client and asks that she review and sign the form, the client says she no longer wants to have the surgery. At this time, which action should the nurse take?

• A. Ask the client why she has changed her mind
• B. Proceed with the surgery
• C. Notify the surgeon immediately
• D. Document the client’s decision

Correct answer: A

Rationale: The correct action for the nurse to take in this situation is to ask the client why she has changed her mind. By understanding the client's reasons for refusal, the nurse can address any concerns, provide further information, and ensure that the client's decision is respected. Proceeding with the surgery without clarifying the client's decision or notifying the surgeon immediately would not be appropriate. Documenting the client's decision is important, but it should be done after understanding the rationale behind the decision.

4. A client with a history of diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What is the most important action for the nurse to take?

• A. Monitor the client's blood glucose level.
• B. Encourage the client to increase fluid intake.
• C. Administer insulin as prescribed.
• D. Assess the client's urine output.

Correct answer: A

Rationale: The most critical action for the nurse to take when a client with diabetes mellitus presents with symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps in assessing the client's current glycemic status and guides further interventions. Encouraging increased fluid intake (Choice B) may be beneficial in managing dehydration caused by polyuria, but it does not address the underlying cause of hyperglycemia. Administering insulin as prescribed (Choice C) may be necessary based on the blood glucose monitoring results, but monitoring should precede any medication administration. Assessing the client's urine output (Choice D) is important but does not directly address the primary concern of evaluating and managing hyperglycemia in a client with diabetes.

5. While measuring a client’s vital signs, the nurse notices an irregularity in the heart rate. Which nursing action is appropriate?

• A. Count the apical pulse rate for 1 full minute, and describe the rhythm in the chart
• B. Measure the blood pressure
• C. Perform an ECG
• D. Recheck the heart rate after 5 minutes

Correct answer: A

Rationale: The appropriate nursing action when an irregularity in the heart rate is observed is to count the apical pulse rate for a full minute and describe the rhythm in the chart. This approach helps in obtaining an accurate assessment of the irregularities present. Measuring the blood pressure (Choice B) is important but not the immediate priority when an irregular heart rate is noted. Performing an ECG (Choice C) may be necessary but is a more advanced intervention that should follow the initial assessment. Rechecking the heart rate after 5 minutes (Choice D) may delay potential interventions for addressing the irregularity, making it less appropriate than the immediate assessment and documentation of the pulse rhythm.
