Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. The nurse is caring for a client with a nasogastric tube. Which of the following interventions is a priority to maintain client safety?

• A. Flush the tube with water every 4 hours
• B. Check the tube placement before each feeding
• C. Secure the tube to the client's nose with tape
• D. Keep the head of the bed elevated at 30 degrees

Correct answer: B

Rationale: Verifying the correct placement of a nasogastric tube before each feeding is essential to prevent aspiration and ensure that the tube is properly positioned in the stomach or intestine. This action is a priority to maintain client safety. Flushing the tube with water every 4 hours is important for tube patency but is not the priority over verifying placement. Securing the tube with tape and keeping the head of the bed elevated are crucial but are considered secondary measures compared to confirming the correct tube placement.

3. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who has been experiencing increasing shortness of breath. Which finding requires immediate intervention?

• A. A respiratory rate of 26 breaths per minute
• B. Use of accessory muscles for breathing
• C. Barrel chest appearance
• D. A pulse oximetry reading of 88%

Correct answer: D

Rationale: A pulse oximetry reading of 88% indicates hypoxemia, which requires immediate intervention to improve oxygenation. Hypoxemia can lead to serious complications if not addressed promptly. While a respiratory rate of 26 breaths per minute and the use of accessory muscles for breathing are concerning in COPD, they do not indicate an immediate life-threatening situation. Similarly, a barrel chest appearance is a common finding in COPD and does not require urgent intervention compared to the critical need to address hypoxemia.

4. A client with deep vein thrombosis (DVT) is prescribed warfarin. What teaching should the nurse provide to the client?

• A. Avoid leafy green vegetables while taking warfarin.
• B. Report any unusual bruising or bleeding.
• C. Take warfarin at the same time every day.
• D. Avoid alcohol consumption while on warfarin.

Correct answer: D

Rationale: The correct answer is D: 'Avoid alcohol consumption while on warfarin.' Alcohol can increase the risk of bleeding when taken with warfarin, so it should be avoided. Choice A is incorrect as leafy green vegetables contain vitamin K, which can interfere with the anticoagulant effects of warfarin. Choice B is important but not directly related to alcohol consumption. Choice C is a general instruction for medication adherence but not specifically related to the interaction with alcohol.

5. A client with heart failure receiving furosemide develops muscle weakness. What is the nurse's priority action?

• A. Administer potassium supplements as prescribed.
• B. Monitor the client’s potassium levels.
• C. Instruct the client to increase their salt intake.
• D. Discontinue the furosemide.

Correct answer: B

Rationale: Muscle weakness in a client receiving furosemide (a diuretic) is often a sign of hypokalemia, as furosemide increases potassium loss. Monitoring potassium levels is essential to identify and address any imbalances and prevent complications such as arrhythmias. Administering potassium supplements without monitoring the levels can lead to hyperkalemia, which has its own set of serious complications. Instructing the client to increase salt intake is not appropriate in this situation as it does not address the underlying electrolyte imbalance. Discontinuing furosemide abruptly can worsen heart failure symptoms; therefore, monitoring potassium levels and adjusting the treatment accordingly is the most appropriate action.
