Nursing Elites

1. Which electrolyte imbalance is common in patients receiving diuretics?

• A. Hypokalemia
• B. Hypercalcemia
• C. Hyponatremia
• D. Hypermagnesemia

Correct answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.

2. A client is being taught how to perform self-catheterization. Which of the following instructions should the nurse include?

• A. Clean the catheter with alcohol after each use.
• B. Perform self-catheterization while sitting on the toilet.
• C. Use a new catheter each time you perform self-catheterization.
• D. Lubricate the catheter tip with petroleum jelly before insertion.

Correct answer: C

Rationale: The correct answer is C: 'Use a new catheter each time you perform self-catheterization.' It is essential to use a new, sterile catheter each time to prevent infection during the procedure. Choice A is incorrect because cleaning the catheter with alcohol may not be sufficient to prevent infection. Choice B is incorrect because self-catheterization is typically done in a clean, private area, not necessarily on the toilet. Choice D is incorrect because lubricating the catheter tip with petroleum jelly is a common practice but not as crucial as using a new catheter each time to prevent infection.

3. Which lab value should be closely monitored for a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor potassium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

4. A nurse is preparing to administer an intermittent enteral feeding to a client who has a gastrostomy tube. Which of the following actions should the nurse take?

• A. Flush the tube with 30 mL of water after feeding
• B. Flush the tube with 10 mL of sterile water before feeding
• C. Place the client in a left lateral position
• D. Place the feeding bag 61 cm (24 in) above the client's abdomen

Correct answer: B

Rationale: Administering an intermittent enteral feeding through a gastrostomy tube requires flushing the tube with 10 mL of sterile water before feeding. This action helps ensure patency and prevents clogging. Choice A is incorrect because flushing after feeding does not address the need for pre-feeding tube flushing. Choice C is unrelated to tube feeding administration. Choice D is incorrect as the height of the feeding bag above the abdomen is typically regulated by healthcare facility policies and is not a universal standard.

5. A nurse is assessing a client who has a peripherally inserted central catheter (PICC). Which of the following findings should the nurse report to the provider?

• A. Redness at the insertion site.
• B. Swelling of the arm above the insertion site.
• C. A bruised area around the insertion site.
• D. A temperature of 37.2°C (99°F).

Correct answer: B

Rationale: Swelling of the arm above the insertion site is concerning as it can indicate complications like thrombosis, which require immediate attention. Redness at the insertion site is common and expected in the initial stages. A bruised area around the insertion site may result from the insertion procedure and is usually not alarming unless it worsens or becomes larger. A temperature of 37.2°C (99°F) is within the normal range and is not directly related to PICC complications.
