Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. An older male client, who is a retired chef, is hospitalized with a diabetic ulcer on his foot. His daughter tells the nurse that her father has become increasingly obsessed with the way his food is prepared in the hospital. The nurse's response should be based on what information?

• A. His daughter's observations suggest the client is depressed
• B. His compulsiveness about food may indicate new cognitive decline
• C. Obsessiveness with food is common in diabetic clients
• D. If the client was compulsive about food when he was younger, the aging process can magnify this

Correct answer: D

Rationale: Age can magnify pre-existing compulsive tendencies. If the client was detail-oriented about food earlier in life, this behavior may intensify with aging. It's important to acknowledge and address the client's concerns respectfully. Choices A, B, and C are incorrect because the daughter's observations do not necessarily point to depression, the compulsiveness about food does not indicate new cognitive decline without further assessment, and obsessiveness with food is not specifically common in diabetic clients.

3. The nurse is providing discharge instructions to a client who has had a stroke. Which intervention should the nurse recommend to prevent aspiration during meals?

• A. Encourage the client to take large bites of food
• B. Advise the client to eat quickly to prevent fatigue
• C. Offer the client thin liquids with meals
• D. Instruct the client to sit upright while eating

Correct answer: D

Rationale: Instructing the client to sit upright while eating is crucial to prevent aspiration in stroke clients. This position helps in safe swallowing and reduces the risk of food or liquid entering the airway. Encouraging the client to take large bites of food (Choice A) can increase the risk of choking and aspiration. Advising the client to eat quickly (Choice B) may lead to fatigue and compromise safe swallowing. Offering thin liquids (Choice C) can also increase the risk of aspiration in stroke clients, as thicker liquids are usually recommended to prevent aspiration.

4. A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.

5. 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.
