Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. A client with a history of heart failure is admitted to the hospital with worsening dyspnea. The nurse notes that the client has a productive cough with pink, frothy sputum. What action should the nurse take first?

• A. Administer oxygen
• B. Perform chest physiotherapy
• C. Elevate the head of the bed
• D. Obtain a sputum specimen

Correct answer: A

Rationale: In a client with heart failure presenting with worsening dyspnea and pink, frothy sputum (indicating pulmonary edema), the priority action for the nurse is to administer oxygen. Oxygen therapy helps improve oxygenation and alleviate dyspnea by increasing the oxygen supply to the lungs. Performing chest physiotherapy, elevating the head of the bed, or obtaining a sputum specimen are not the initial actions indicated in this situation and may delay addressing the client's immediate need for improved oxygenation.

3. A client who is 32-weeks pregnant is diagnosed with partial placenta previa. Which instruction should the nurse include in this client’s teaching plan?

• A. Wear a tight abdominal binder at all times
• B. Take a daily laxative to prevent constipation
• C. Refrain from sexual intercourse until your next appointment
• D. Restrict fluids to less than 1000 ml per day

Correct answer: C

Rationale: Refraining from sexual intercourse helps prevent complications with partial placenta previa.

4. Oxygen at liters/min per nasal cannula PRN difficult breathing is prescribed for a client with pneumonia. Which nursing intervention is effective in preventing oxygen toxicity?

• A. Avoiding the administration of high levels of oxygen for extended periods.
• B. Administering a sedative at bedtime to slow the client's respiratory rate.
• C. Removing the nasal cannula during the night to prevent oxygen buildup.
• D. Running oxygen through a hydration source prior to administration.

Correct answer: A

Rationale: The correct answer is A: Avoiding the administration of high levels of oxygen for extended periods. Oxygen toxicity can occur when high levels of oxygen are given for a prolonged period. It is important to monitor and adjust the oxygen levels as needed to prevent toxicity. Choice B is incorrect because administering a sedative to slow the respiratory rate does not directly prevent oxygen toxicity. Choice C is incorrect as removing the nasal cannula during the night can compromise the client's oxygenation. Choice D is incorrect as running oxygen through a hydration source does not prevent oxygen toxicity; instead, it may introduce risks associated with the hydration source.

5. The nurse is planning care for a client with a stage III pressure ulcer. Which intervention is most important for the nurse to include in the plan of care?

• A. Reposition the client every 2 hours
• B. Cleanse the ulcer with normal saline
• C. Apply a moisture-retentive dressing
• D. Measure the ulcer's depth and diameter

Correct answer: D

Rationale: The correct answer is to measure the ulcer's depth and diameter. This intervention is crucial as it helps monitor healing progress and evaluate the effectiveness of the care plan. Measuring the ulcer provides valuable information about the wound's improvement or deterioration. Repositioning the client every 2 hours (Choice A) is important for preventing further skin breakdown but may not be the priority in this case. Cleansing the ulcer with normal saline (Choice B) is essential for wound care but not the most crucial intervention at this stage. Applying a moisture-retentive dressing (Choice C) can promote healing, but assessing the ulcer's dimensions is more critical for monitoring progress.
