Nursing Elites

1. A client with type 1 diabetes mellitus is being taught self-administration of insulin by a nurse. Which of the following instructions should the nurse include?

• A. Inject air into the vial before withdrawing the insulin.
• B. Draw up the short-acting insulin first, then the long-acting insulin.
• C. Store unopened insulin vials in the freezer.
• D. Rotate injection sites within the same anatomical region.

Correct answer: D

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same anatomical region. This practice helps reduce the risk of lipodystrophy, a condition characterized by fatty tissue changes due to repeated insulin injections in the same spot. By rotating sites, the client ensures better insulin absorption and prevents localized skin changes. Injecting air into the vial before withdrawing insulin (Choice A) is unnecessary and not recommended. Drawing up short-acting insulin before long-acting insulin (Choice B) is not a standard practice and can lead to errors in dosing. Storing unopened insulin vials in the freezer (Choice C) is incorrect as insulin should be stored in the refrigerator, not the freezer, to maintain its effectiveness.

2. A nurse is providing discharge teaching to a client who has a new prescription for lithium. Which of the following instructions should the nurse include?

• A. Take this medication on an empty stomach.
• B. Avoid eating foods that contain tyramine.
• C. Drink at least 2 liters of water each day.
• D. Take this medication in the evening before bedtime.

Correct answer: C

Rationale: The correct instruction for a client prescribed lithium is to drink at least 2 liters of water each day. This is important to prevent dehydration and reduce the risk of lithium toxicity. Option A is incorrect because lithium is usually taken with food to minimize gastrointestinal side effects. Option B is unrelated to lithium and is more applicable to clients taking MAOIs. Option D is incorrect as lithium is typically taken in divided doses throughout the day to maintain therapeutic levels.

3. A nurse is caring for a client who has a Clostridium difficile infection. Which of the following precautions should the nurse implement?

• A. Place the client in a negative pressure room
• B. Wear an N95 respirator mask when entering the room
• C. Wear a gown and gloves when providing care to the client
• D. Place a face mask on the client

Correct answer: C

Rationale: The correct precaution to implement when caring for a client with Clostridium difficile infection is to wear a gown and gloves when providing care. Clostridium difficile is primarily spread through contact with feces, so wearing personal protective equipment like gowns and gloves is crucial in preventing the spread of the infection. Placing the client in a negative pressure room (Choice A) is not necessary for Clostridium difficile. While wearing an N95 respirator mask (Choice B) is important for airborne precautions, it is not required for Clostridium difficile. Placing a face mask on the client (Choice D) is not a standard precaution for preventing the spread of Clostridium difficile.

4. A nurse is caring for a client who is receiving warfarin therapy. Which of the following laboratory results indicates the need for an increase in the dose of warfarin?

• A. PT 28 seconds
• B. INR 1.2
• C. aPTT 40 seconds
• D. Fibrinogen 350 mg/dL

Correct answer: B

Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

5. A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory tests should the nurse use to monitor the client's therapeutic response to the medication?

• A. INR
• B. aPTT
• C. Platelet count
• D. Hemoglobin A1C

Correct answer: A

Rationale: The correct answer is A: INR. The INR (International Normalized Ratio) is the laboratory test used to monitor the therapeutic response of warfarin. It helps ensure that the client's clotting time is within the desired range to prevent complications such as excessive bleeding or clotting. Choice B, aPTT (Activated Partial Thromboplastin Time), is not typically used to monitor warfarin therapy but rather for assessing heparin therapy. Choice C, Platelet count, assesses the number of platelets in the blood and is not specifically used to monitor warfarin therapy. Choice D, Hemoglobin A1C, is a test used to monitor long-term blood sugar control in diabetic patients and is not relevant to monitoring warfarin therapy.
