Nursing Elites

1. A nurse is assessing a client who has a history of atrial fibrillation and is receiving warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Bleeding time
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). The INR is used to monitor the effectiveness of warfarin therapy. A higher INR indicates a longer time it takes for the blood to clot, which is desirable in patients receiving warfarin to prevent blood clots. Platelet count (Choice A) assesses the number of platelets in the blood and is not directly related to warfarin therapy. Bleeding time (Choice C) evaluates the time it takes for a person to stop bleeding after a standardized wound, but it is not specific to monitoring warfarin effectiveness. Partial thromboplastin time (PTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.

2. A client is newly diagnosed with hypothyroidism and prescribed levothyroxine. Which of the following instructions should the nurse include?

• A. Take the medication with food.
• B. Take the medication in the evening.
• C. Take the medication on an empty stomach.
• D. Take the medication only when experiencing symptoms.

Correct answer: C

Rationale: The correct instruction is to take levothyroxine on an empty stomach. This is necessary for proper absorption and effectiveness of the medication. Taking it with food can interfere with absorption. Timing is also crucial; it is usually recommended to take levothyroxine in the morning to prevent potential interactions with food and other medications throughout the day. Taking the medication in the evening may lead to sleep disturbances. Lastly, waiting to take the medication only when symptoms occur is not appropriate as levothyroxine is typically taken regularly to maintain thyroid hormone levels within the body.

3. A nurse is reviewing the medication metformin with a client who has diabetes. Which of the following side effects should the nurse discuss?

• A. Gastrointestinal upset
• B. Increased appetite
• C. Weight loss
• D. Frequent urination

Correct answer: A

Rationale: The correct answer is A: Gastrointestinal upset. Metformin can cause gastrointestinal upset, especially when first starting therapy. It is important to take it with food to reduce these effects. Increased appetite (choice B) and weight loss (choice C) are not common side effects of metformin but may occur due to improved blood sugar control. Frequent urination (choice D) is a symptom of uncontrolled diabetes and not a side effect of metformin.

4. A nurse is caring for a toddler diagnosed with respiratory syncytial virus (RSV). Which of the following actions should the nurse take?

• A. Use a designated stethoscope when caring for the toddler
• B. Wear an N95 respirator mask
• C. Remove the disposable gown after leaving the toddler’s room
• D. Place the toddler in a room with negative air pressure

Correct answer: A

Rationale: Using a designated stethoscope is the correct action when caring for a toddler diagnosed with RSV. This measure helps prevent the spread of infection to other clients by reducing the risk of contamination. Wearing an N95 respirator mask is not necessary for routine care of a toddler with RSV unless performing aerosol-generating procedures. Removing the disposable gown after leaving the toddler's room is important for infection control but not specific to RSV care. Placing the toddler in a room with negative air pressure is not a standard practice for managing RSV in toddlers.

5. A nurse in an outpatient facility is assessing a client who is prescribed furosemide 40 mg daily, but the client reports she has been taking extra doses to promote weight loss. Which of the following findings indicates she is dehydrated?

• A. Urine specific gravity of 1.020
• B. Urine specific gravity of 1.035
• C. Decreased skin turgor
• D. Decreased heart rate

Correct answer: B

Rationale: The correct answer is B. A urine specific gravity greater than 1.030 is indicative of dehydration as it reflects concentrated urine. Choice A is incorrect as a specific gravity of 1.020 is within the normal range. Choice C, decreased skin turgor, can be a sign of dehydration but is not as specific as urine specific gravity. Choice D, decreased heart rate, is not typically a direct indicator of dehydration.
