Nursing Elites

1. The healthcare professional is administering an intermittent infusion of an antibiotic to a client with an antecubital saline lock. After opening the roller clamp on the IV tubing, the alarm on the infusion pump indicates an obstruction. What action should be taken first?

• A. Check for a blood return.
• B. Reposition the client's arm.
• C. Remove the IV site dressing.
• D. Flush the lock with saline.

Correct answer: B

Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.

2. A client is scheduled for a colonoscopy. What instruction should the nurse provide to prepare the client for the procedure?

• A. Drink clear liquids for 24 hours before the procedure
• B. Take a laxative the morning of the procedure
• C. Eat a light meal before the procedure
• D. Avoid drinking fluids for 4 hours before the procedure

Correct answer: A

Rationale: The correct instruction for preparing a client for a colonoscopy is to drink clear liquids for 24 hours before the procedure. This step helps to ensure the bowel is adequately cleared for the colonoscopy, allowing for better visualization and examination of the colon.

3. The healthcare provider obtains a BP reading of 100/88 in the right arm of a client whose blood pressure is typically 120/60 in the same arm. What action should the healthcare provider implement first?

• A. Use an electronic sphygmomanometer to take the BP every 30 minutes.
• B. Retake the blood pressure in the same arm, deflating the cuff slowly.
• C. Ask another healthcare provider to recheck the blood pressure to compare results.
• D. Obtain another blood pressure cuff and retake the blood pressure.

Correct answer: B

Rationale: The healthcare provider should first retake the blood pressure in the right arm, deflating the cuff slowly, because a low systolic and high diastolic blood pressure measurement is often the result of deflating the cuff too rapidly. Taking the BP in the same arm ensures consistency and accuracy of the measurement.

4. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Serum sodium level.
• B. Serum potassium level.
• C. Serum calcium level.
• D. Serum glucose level.

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

5. A client being discharged with a prescription for the bronchodilator theophylline is instructed to take three doses of the medication each day. Since timed-release capsules are not available, which dosing schedule should the nurse advise the client to follow?

• A. 9 a.m., 1 p.m., and 5 p.m.
• B. 8 a.m., 4 p.m., and midnight.
• C. Before breakfast, before lunch, and before dinner.
• D. With breakfast, with lunch, and with dinner.

Correct answer: B

Rationale: Theophylline should be administered on a regular around-the-clock schedule to provide the best bronchodilating effect and reduce the potential for adverse effects. The correct dosing schedule of 8 a.m., 4 p.m., and midnight ensures that the client receives consistent dosing throughout the day. Other options do not provide the necessary around-the-clock coverage. It's important to note that food may affect the absorption of the medication, which is why the dosing schedule should not be tied to meal times.
