Nursing Elites

1. When obtaining a urine specimen for a culture and sensitivity from an indwelling catheter, the nurse should:

• A. Cleanse the entry port prior to withdrawing urine.
• B. Use a sterile syringe to collect urine from the collection bag.
• C. Obtain the specimen from the drainage tubing.
• D. Replace the catheter before obtaining the specimen.

Correct answer: A

Rationale: The correct procedure when obtaining a urine specimen from an indwelling catheter for culture and sensitivity is to cleanse the entry port before withdrawing urine. This step helps reduce the risk of contamination and ensures the accuracy of the results. Option B is incorrect because using a sterile syringe to collect urine from the collection bag is not the recommended method for obtaining a catheter specimen. Option C is incorrect as obtaining the specimen from the drainage tubing is not the appropriate technique for collecting a urine sample from an indwelling catheter. Option D is incorrect because replacing the catheter before obtaining the specimen is not necessary and may introduce unnecessary complications.

2. When assessing a male client, the nurse finds that he is fatigued and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?

• A. Hyperphosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.

3. A client has a new cast on the left arm, and the nurse is assessing the client. Which of the following findings should the nurse report to the provider immediately?

• A. Increased warmth in the affected arm
• B. Itching under the cast
• C. Pain with passive movement
• D. Drainage on the cast

Correct answer: C

Rationale: The correct answer is C: Pain with passive movement. Pain with passive movement in a client with a new cast can indicate compartment syndrome, a serious condition where pressure builds up within the muscles, nerves, and blood vessels of the affected limb, potentially leading to tissue damage. Immediate reporting is crucial to prevent further complications. Increased warmth in the affected arm could be a normal inflammatory response to the injury and casting process. Itching under the cast is common and can be managed without immediate concern. Drainage on the cast may be expected initially after casting due to residual moisture from the setting process, but ongoing or excessive drainage should be monitored and reported if persistent.

4. A client with a history of hypertension is prescribed a beta-blocker. Which side effect should the LPN/LVN monitor for in this client?

• A. Increased appetite
• B. Dry mouth
• C. Bradycardia
• D. Insomnia

Correct answer: C

Rationale: The correct side effect that the LPN/LVN should monitor for in a client prescribed a beta-blocker is bradycardia. Beta-blockers work by slowing down the heart rate, which can lead to bradycardia as a common side effect. Monitoring the client's heart rate is crucial, as bradycardia can be a serious condition. Choices A, B, and D are incorrect because increased appetite, dry mouth, and insomnia are not typically associated with beta-blockers. Increased appetite is more commonly linked to certain medications like corticosteroids, dry mouth can be a side effect of anticholinergic medications, and insomnia may be a side effect of stimulant medications.

5. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?

• A. 8 mL/hr
• B. 10 mL/hr
• C. 12 mL/hr
• D. 15 mL/hr

Correct answer: A

Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.
