Nursing Elites

1. A healthcare professional is preparing to administer gentamicin 2 mg/kg via IV bolus to a client who weighs 220 lb. How many mg should the healthcare professional administer?

• A. 200 mg
• B. 100 mg
• C. 160 mg
• D. 180 mg

Correct answer: C

Rationale: To calculate the dosage correctly, the weight in pounds must first be converted to kilograms. 220 lb / 2.2 = 100 kg. Then, multiply the weight in kg by the dosage of 2 mg/kg: 2 mg/kg × 100 kg = 200 mg. Therefore, the correct dosage to administer is 200 mg, which is closest to option A. Option C (160 mg) is incorrect because it does not match the calculated dosage. Options B (100 mg) and D (180 mg) are also incorrect as they do not align with the correct calculation.

2. A client is experiencing dehydration, and the nurse is planning care. Which of the following actions should the nurse include?

• A. Administer antihypertensives as prescribed.
• B. Check the client’s weight daily.
• C. Notify the provider if the urine output is less than 30 mL/hr.
• D. Encourage the client to ambulate independently four times a day.

Correct answer: B

Rationale: Checking the client's weight daily is essential for monitoring fluid status in dehydration. Administering antihypertensives, notifying the provider of insufficient urine output, and encouraging ambulation are not primary interventions for managing dehydration. Administering antihypertensives may affect blood pressure, but it is not a direct intervention for dehydration. Notifying the provider of a urine output less than 30 mL/hr indicates oliguria, which is a sign of reduced kidney function rather than dehydration. Encouraging ambulation is a general nursing intervention and does not directly address the fluid imbalance associated with dehydration.

3. The healthcare provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How much should the LPN/LVN plan to administer?

• A. 1/2 tablet.
• B. 1 tablet.
• C. 1 1/2 tablets.
• D. 2 tablets.

Correct answer: C

Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.

4. The nurse is caring for a client with a central venous catheter. What is the most important action for the nurse to take to prevent infection?

• A. Change the catheter dressing every 72 hours.
• B. Flush the catheter with heparin solution daily.
• C. Ensure the catheter is clamped when not in use.
• D. Maintain sterile technique when handling the catheter.

Correct answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. Changing the catheter dressing every 72 hours, while important for overall catheter care, does not directly address infection prevention. Flushing the catheter with heparin solution daily is essential for maintaining patency but does not primarily prevent infections. Ensuring the catheter is clamped when not in use is important for preventing air embolism but is not the most critical action to prevent infection. The most effective way to prevent infections is by strictly adhering to sterile techniques during catheter handling, which minimizes the risk of introducing pathogens into the catheter site.

5. A healthcare provider is preparing to perform mouth care for an unresponsive client. Which of the following actions should the healthcare provider plan to take?

• A. Raise the level of the bed
• B. Administer mouth care with the client in a supine position
• C. Use a tongue depressor to open the mouth
• D. Place the client in a prone position

Correct answer: A

Rationale: Raising the bed level is the correct action to facilitate easier access for mouth care in an unresponsive client. This position enhances the safety and comfort of both the client and the healthcare provider. Administering mouth care with the client in a supine position (lying flat on their back) can increase the risk of aspiration. Using a tongue depressor to open the mouth is not recommended as it can cause discomfort and potential injury. Placing the client in a prone position (lying face down) is contraindicated for mouth care and can compromise the client's airway.
