Nursing Elites

1. A client is prescribed 1g of potassium phosphate IV to be infused continuously over 6 hr. Available is 1 g in 250 ml of dextrose 5%. What rate should the nurse set the IV pump to run at?

• A. 40 ml/hr
• B. 42 ml/hr
• C. 44 ml/hr
• D. 46 ml/hr

Correct answer: B

Rationale: To calculate the IV rate, divide the total volume by the total time in hours. In this case, 1 g in 250 ml is to be infused over 6 hours. Therefore, 250 ml / 6 hr = 42 ml/hr. This means the IV pump should be set to run at 42 ml/hr. Choices A, C, and D are incorrect as they do not accurately calculate the infusion rate based on the provided information.

2. A nurse is preparing to administer medication to a client by nasogastric tube. What should the nurse do first?

• A. Administer the medication without further assessment.
• B. Check the tube placement before administering any medication.
• C. Administer the medication in liquid form only.
• D. Administer half the dosage as a precaution.

Correct answer: B

Rationale: The correct answer is B: Check the tube placement before administering any medication. Before administering medication through a nasogastric tube, the nurse must first verify the tube's correct placement to ensure the medication reaches the stomach and to prevent complications such as aspiration. Options A, C, and D are incorrect because administering medication without confirming proper tube placement can lead to serious consequences for the client.

3. When teaching a patient about self-administration of insulin, what is the most important instruction to provide?

• A. Rotate injection sites to prevent tissue damage.
• B. Inject insulin at a 90-degree angle for proper absorption.
• C. Store insulin in the refrigerator to maintain potency.
• D. Teach the patient to administer insulin at the same time each day.

Correct answer: A

Rationale: The most important instruction to provide when teaching a patient about self-administration of insulin is to rotate injection sites to prevent tissue damage. Rotating injection sites helps prevent lipodystrophy (tissue damage) and ensures proper insulin absorption. Option B is incorrect because the angle of insulin injection varies depending on the patient's body composition. Injecting at a 90-degree angle is not always necessary. Option C is not the most crucial instruction; while storing insulin in the refrigerator is important, it is not the priority when teaching self-administration. Option D is also important for maintaining consistency but is not as critical as rotating injection sites to prevent tissue damage.

4. Which of the following is a critical nursing action when managing a patient with a chest tube?

• A. Keep the chest tube clamped at all times.
• B. Ensure the chest tube is connected to a closed drainage system.
• C. Empty the chest tube drainage system every 2 hours.
• D. Disconnect the chest tube when the patient is ambulating.

Correct answer: B

Rationale: The correct answer is B: "Ensure the chest tube is connected to a closed drainage system." This is a critical nursing action when managing a patient with a chest tube because it is essential for proper drainage and to prevent complications such as air leaks or infections. Option A is incorrect because keeping the chest tube clamped at all times would prevent proper drainage and could lead to complications. Option C is incorrect as emptying the chest tube drainage system should be done based on assessment findings rather than a fixed time interval. Option D is incorrect because disconnecting the chest tube when the patient is ambulating can lead to complications like a pneumothorax.

5. A nurse is assessing a client who has asthma. Which of the following areas should the nurse evaluate as the most reliable indicator of central cyanosis?

• A. Oral mucosa
• B. Conjunctivae
• C. Soles of the feet
• D. Ear lobes

Correct answer: A

Rationale: Central cyanosis is best assessed by examining the oral mucosa, as it is a more reliable indicator compared to other areas like the conjunctivae, soles of the feet, and ear lobes. The oral mucosa reflects the oxygen saturation levels of the blood more accurately. Conjunctivae and ear lobes may show cyanosis, but they are not as reliable as the oral mucosa. The soles of the feet are not typically used to assess central cyanosis.
