Nursing Elites

1. The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?

• A. Blood glucose
• B. Serum sodium
• C. Serum potassium
• D. Blood urea nitrogen (BUN)

Correct answer: C

Rationale: The correct answer is C: Serum potassium. When a client is receiving furosemide, a loop diuretic, it can lead to potassium loss. Monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias. Blood glucose (Choice A) is not directly impacted by furosemide. Serum sodium (Choice B) may be affected, but monitoring potassium is more critical due to the risk of arrhythmias. Blood urea nitrogen (BUN) (Choice D) is important for assessing kidney function but is not the most crucial value to monitor in a client taking furosemide.

2. A client is receiving intravenous heparin therapy for the treatment of deep vein thrombosis (DVT). Which laboratory test result should the LPN/LVN monitor to ensure the client is receiving a therapeutic dose?

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

Correct answer: B

Rationale: The correct laboratory test result that the LPN/LVN should monitor to ensure the client is receiving a therapeutic dose of heparin therapy is the activated partial thromboplastin time (aPTT). The aPTT test is specifically used to monitor heparin therapy, ensuring that the dose administered is within the therapeutic range. Monitoring aPTT helps to prevent complications such as bleeding or clot formation by maintaining the appropriate anticoagulant effect of heparin. Prothrombin time (PT) and International normalized ratio (INR) are more commonly used to monitor warfarin therapy, not heparin. Platelet count is not a direct indicator of heparin's therapeutic effect and is not used to monitor heparin therapy.

3. The client with diabetes mellitus has gangrene of the toes to the midfoot. Which goal should be included in this client's plan of care?

• A. Restore skin integrity.
• B. Prevent infection.
• C. Promote healing.
• D. Improve nutrition.

Correct answer: B

Rationale: Preventing infection is crucial in clients with gangrene to halt the spread of infection and avert further complications. Infections can exacerbate tissue damage and lead to systemic complications, making infection prevention a priority in the care plan for this client. Restoring skin integrity and promoting healing may not be achievable goals until the infection is under control. Improving nutrition is important for overall health but may not be the priority when the immediate concern is preventing infection.

4. A client has a new prescription for rifampin. Which of the following instructions should the nurse include?

• A. Take the medication with food.
• B. Expect red-orange discoloration of body fluids.
• C. Monitor for signs of hyperglycemia.
• D. Avoid consuming dairy products.

Correct answer: B

Rationale: The correct answer is to inform the client to expect red-orange discoloration of body fluids when taking rifampin. Rifampin is known to cause this side effect, which is harmless but can be surprising to patients. It is important for the nurse to educate the client about this expected change to prevent unnecessary concern or alarm. Monitoring for hyperglycemia is not directly related to rifampin, and taking the medication with food or avoiding dairy products are not specific instructions for this medication.

5. The client is being taught about the use of sublingual nitroglycerin for chest pain. Which instruction should be provided?

• A. Swallow the tablet whole with water.
• B. Place the tablet under the tongue and let it dissolve.
• C. Chew the tablet and then swallow.
• D. Place the tablet between the cheek and gum.

Correct answer: B

Rationale: The correct method for administering sublingual nitroglycerin is to place the tablet under the tongue and allow it to dissolve. This route of administration facilitates rapid absorption of the medication into the bloodstream, enabling quick relief of chest pain associated with angina or heart conditions. Choice A is incorrect because sublingual nitroglycerin should not be swallowed whole. Choice C is wrong as chewing the tablet can lead to the rapid release of the drug, causing adverse effects like headaches or dizziness. Choice D is also incorrect as the tablet should not be placed between the cheek and gum, but under the tongue for proper absorption.
