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

• A. Avoid foods high in vitamin K, such as spinach.
• B. Report any signs of bleeding, such as bruising or nosebleeds.
• C. Take the medication on an empty stomach.
• D. Monitor for changes in blood pressure.

Correct answer: B

Rationale: The correct teaching for a client prescribed warfarin is to report any signs of bleeding, such as unusual bruising, nosebleeds, or blood in the urine or stool. Warfarin is an anticoagulant that increases the risk of bleeding, so it is crucial for the client to promptly report any bleeding-related symptoms for evaluation by a healthcare provider. Choices A, C, and D are incorrect. Avoiding foods high in vitamin K, such as spinach, is more relevant for clients taking warfarin to maintain consistent vitamin K intake. Warfarin should be taken with food to avoid gastrointestinal upset, so taking it on an empty stomach is not recommended. Monitoring for changes in blood pressure is not directly related to warfarin therapy; instead, the focus should be on monitoring for signs of bleeding.

3. The nurse is providing discharge teaching to a client with asthma. Which statement indicates the client understands how to use a rescue inhaler?

• A. I will use my rescue inhaler every morning to prevent asthma attacks.
• B. I should use my rescue inhaler when I start to experience wheezing.
• C. I will use my rescue inhaler when my peak flow meter reading is in the green zone.
• D. I will only use my rescue inhaler before going to bed.

Correct answer: B

Rationale: The correct answer is B: 'I should use my rescue inhaler when I start to experience wheezing.' A rescue inhaler is used during the onset of asthma symptoms, such as wheezing, to quickly open the airways. It is not intended for routine daily use or prevention, which is the role of a maintenance inhaler. Option A is incorrect because a rescue inhaler is not used for prevention but for immediate relief during an asthma attack. Option C is incorrect because the peak flow meter reading is used to monitor asthma control, not to determine when to use a rescue inhaler. Option D is incorrect because using a rescue inhaler only before going to bed does not address the need for immediate relief when wheezing or experiencing asthma symptoms.

4. A client with diabetes mellitus presents with a blood sugar level of 320 mg/dL. What is the nurse's initial action?

• A. Administer sliding scale insulin as prescribed
• B. Encourage the client to drink fluids
• C. Provide the client with a carbohydrate snack
• D. Assess the client for signs of hypoglycemia

Correct answer: A

Rationale: When a client with diabetes mellitus presents with a high blood sugar level of 320 mg/dL, the nurse's initial action should be to administer sliding scale insulin as prescribed. The priority is to bring down the elevated glucose level promptly to prevent further complications. Encouraging the client to drink fluids or providing a carbohydrate snack would not effectively address the elevated blood sugar level in this scenario. Assessing for signs of hypoglycemia is not appropriate as the client's blood sugar level is high, not low.

5. An older client with type 1 diabetes arrives at the clinic with abdominal cramping, vomiting, lethargy, and confusion. What should the nurse implement first?

• A. Start an IV infusion of normal saline.
• B. Obtain a serum potassium level.
• C. Administer the client's usual dose of insulin.
• D. Assess the pupillary response to light.

Correct answer: A

Rationale: The correct answer is A: Start an IV infusion of normal saline. The client is showing signs of dehydration, such as abdominal cramping, vomiting, lethargy, and confusion, which can be exacerbated by hyperglycemia. Rehydration is the initial priority to address the fluid imbalance. Option B, obtaining a serum potassium level, though important in the management of diabetes, is not the immediate priority over rehydration. Option C, administering the client's usual dose of insulin, should only be done after addressing the dehydration and confirming the client's blood glucose levels. Option D, assessing the pupillary response to light, is not the most urgent intervention needed in this situation compared to rehydration to correct fluid imbalance.
