Nursing Elites

1. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?

• A. Bleeding time
• B. Coagulation time
• C. Prothrombin time
• D. Partial thromboplastin time

Correct answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.

2. What action should the nurse take to prevent the development of deep vein thrombosis (DVT) in a client who is postoperative day 2 following hip replacement surgery?

• A. Encourage the client to remain on bed rest as much as possible.
• B. Apply sequential compression devices (SCDs) to the client's legs.
• C. Massage the client's legs to improve circulation.
• D. Encourage the client to perform ankle and foot exercises.

Correct answer: B

Rationale: The correct action to prevent DVT in a postoperative client is to apply sequential compression devices (SCDs) to promote venous return. This helps prevent stasis of blood in the lower extremities, reducing the risk of clot formation. Encouraging bed rest (Choice A) may lead to decreased mobility and increase the risk of DVT. Massaging the client's legs (Choice C) is contraindicated in the presence of DVT as it can dislodge a clot. Encouraging ankle and foot exercises (Choice D) may be beneficial for circulation, but SCDs are more effective at preventing DVT in this scenario.

3. A client with heart failure is being taught by a nurse on reducing daily sodium intake. What is the most important factor in determining the client's ability to learn new dietary habits?

• A. The involvement of the client in planning the change
• B. The presence of a dietitian during the teaching
• C. The use of dietary supplements
• D. The client's family support

Correct answer: A

Rationale: The most crucial factor in the client's ability to learn new dietary habits is their involvement in planning the change. When clients actively participate in setting their dietary goals, they are more likely to commit to and adhere to the changes. This empowerment fosters a sense of ownership and responsibility, enhancing the chances of successful dietary modifications. The presence of a dietitian, use of dietary supplements, and family support, while beneficial, are not as critical as the client's active participation in planning the dietary changes.

4. A client with diabetes mellitus is being taught by a nurse how to perform a capillary blood glucose test. Which of the following instructions should the nurse include in the teaching?

• A. Don sterile gloves after cleansing the site
• B. Puncture the site after cleansing and before the antiseptic dries
• C. Gently wipe the puncture site until a large droplet of blood forms
• D. Hold the finger below the heart level to puncture

Correct answer: B

Rationale: The correct instruction is to puncture the site after cleansing and before the antiseptic dries. This sequence helps ensure proper blood collection without introducing contaminants. Choice A is incorrect because wearing sterile gloves is not necessary for capillary blood glucose testing. Choice C is incorrect as wiping the puncture site can introduce contaminants and alter the blood sample. Choice D is incorrect as holding the finger below the heart level is not required for a capillary blood glucose test.

5. A healthcare provider is preparing to insert an IV catheter into a client's arm before starting IV fluid therapy. Which of the following interventions should the provider implement to prevent infection?

• A. Thread the IV catheter so that the hub rests at the insertion site
• B. Shave excess hair from around the insertion site
• C. Cleanse the site with hydrogen peroxide before IV catheter insertion
• D. Palpate the site carefully just before inserting the IV catheter

Correct answer: A

Rationale: Inserting the IV catheter so that the hub rests at the insertion site reduces the risk of contamination along the length of the catheter. This technique helps prevent introducing microbes into the bloodstream during the catheter insertion process. Shaving excess hair is unnecessary and can increase the risk of skin irritation and infection. Cleansing the site with hydrogen peroxide is outdated as it can cause tissue damage and delay wound healing. Palpating the site just before insertion can introduce bacteria from the skin surface into the insertion site, increasing the risk of infection.
