Nursing Elites

1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A nurse is assessing a client who has heart failure and is receiving furosemide. Which of the following findings should the nurse identify as an indication that the client is developing hypokalemia?

• A. Positive Trousseau's sign.
• B. Hyperactive reflexes.
• C. Hypoactive bowel sounds.
• D. Decreased deep-tendon reflexes.

Correct answer: A

Rationale: The correct answer is A: Positive Trousseau's sign. When a patient receiving furosemide is developing hypokalemia, they may exhibit a positive Trousseau's sign, an indication of low potassium levels. This sign is elicited by inflating a blood pressure cuff above systolic pressure for a few minutes, resulting in carpal spasm. Choices B, C, and D are incorrect. Hyperactive reflexes are associated with hyperkalemia, not hypokalemia. Hypoactive bowel sounds are not specifically related to hypokalemia. Decreased deep-tendon reflexes are not typically seen in hypokalemia.

3. A client with COPD is receiving discharge teaching. Which statement indicates an understanding of the teaching?

• A. I will avoid breathing deeply while using my incentive spirometer.
• B. I will limit my fluid intake to 1 liter per day.
• C. I will exercise in an area that is humid.
• D. I will use pursed-lip breathing techniques.

Correct answer: D

Rationale: The correct answer is D. Using pursed-lip breathing techniques is beneficial for clients with COPD as it helps control shortness of breath by keeping airways open longer. Option A is incorrect as deep breathing while using an incentive spirometer is essential to prevent complications such as atelectasis. Option B is incorrect because limiting fluid intake to 1 liter per day is not a standard recommendation for clients with COPD. Option C is incorrect as exercising in a humid area can exacerbate breathing difficulties for clients with COPD.

4. A patient is receiving radiation therapy. Which of the following skin care instructions should the nurse provide?

• A. Apply a heating pad to the radiation site.
• B. Use scented lotions to moisturize the skin.
• C. Keep the radiation site covered with a bandage.
• D. Wear loose clothing over the radiation site.

Correct answer: D

Rationale: Correct Answer: The nurse should instruct the patient to wear loose clothing over the radiation site. This helps prevent skin irritation and promotes healing by reducing friction and irritation on the treated area.\nChoice A is incorrect because applying a heating pad can further irritate the skin that is already sensitive due to radiation therapy.\nChoice B is incorrect because scented lotions may contain ingredients that could further irritate the skin.\nChoice C is incorrect because covering the radiation site with a bandage can trap moisture and lead to skin breakdown, increasing the risk of infection.

5. What is the priority nursing intervention for a patient with a stage 3 pressure ulcer?

• A. Apply hydrocolloid dressing
• B. Provide wound debridement
• C. Change the dressing daily
• D. Elevate the affected area

Correct answer: A

Rationale: The correct answer is to apply a hydrocolloid dressing. Stage 3 pressure ulcers are characterized by full-thickness skin loss involving damage to or necrosis of subcutaneous tissue, which requires a moist environment for healing. Hydrocolloid dressings help maintain a moist wound environment, promote healing, and provide protection. Providing wound debridement may be necessary but is not the priority intervention at this stage. Changing the dressing daily is important for wound care but not the priority over creating an optimal healing environment. Elevating the affected area can help with circulation and reduce swelling, but it is not the priority intervention for a stage 3 pressure ulcer.
