Nursing Elites

1. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?

• A. 8 mL/hr
• B. 10 mL/hr
• C. 12 mL/hr
• D. 15 mL/hr

Correct answer: A

Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.

2. The client with diabetes is being educated by the nurse on foot care. Which statement by the client indicates a need for further teaching?

• A. I will check my feet daily for any cuts or sores.
• B. I will avoid walking barefoot.
• C. I will soak my feet in warm water every day.
• D. I will wear shoes that fit well to avoid blisters.

Correct answer: C

Rationale: The correct answer is C. Soaking the feet in warm water daily is not recommended for clients with diabetes as it can cause the skin to become too soft, increasing the risk of skin breakdown and infections. Checking the feet daily for cuts or sores (A) is a good practice to prevent complications. Avoiding walking barefoot (B) helps protect the feet from injuries. Wearing well-fitted shoes (D) is essential to prevent blisters and other foot problems in diabetic clients. Therefore, the client's statement about soaking the feet in warm water daily indicates a need for further teaching.

3. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD). Which instruction should the LPN/LVN reinforce to the client to help manage their condition?

• A. Increase fluid intake to thin secretions.
• B. Practice pursed-lip breathing to improve oxygenation.
• C. Avoid physical activity to prevent dyspnea.
• D. Use a peak flow meter to monitor lung function.

Correct answer: B

Rationale: Practicing pursed-lip breathing is an essential technique to help manage COPD as it can improve oxygenation by promoting better gas exchange. This technique helps to keep the airways open longer during exhalation, preventing air trapping and improving breathing efficiency. Increasing fluid intake can help thin secretions, which is beneficial, but it is not the primary instruction for managing COPD. Avoiding physical activity is not recommended as it can lead to deconditioning and worsen dyspnea in COPD patients. Using a peak flow meter is more commonly associated with monitoring asthma rather than COPD, so it is not the most relevant instruction for managing COPD.

4. A nurse at a health department is planning strategies related to heart disease. Which of the following activities should the nurse include as part of primary prevention?

• A. Providing cholesterol screening
• B. Teaching about a healthy diet
• C. Providing information about antihypertensive medications
• D. Developing a list of cardiac rehabilitation programs

Correct answer: B

Rationale: Teaching about a healthy diet is considered a primary prevention activity. Primary prevention aims to prevent the onset of a disease or health problem. Educating individuals on healthy lifestyle choices, such as diet modification, falls under primary prevention. Providing cholesterol screening (choice A) is a secondary prevention measure aimed at early detection. Offering information about antihypertensive medications (choice C) falls under secondary prevention, focusing on controlling risk factors. Developing a list of cardiac rehabilitation programs (choice D) is part of tertiary prevention, focusing on rehabilitation and improving outcomes post-disease onset.

5. 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.
