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. What assessment technique should the nurse use to monitor a client for a common untoward effect of phenytoin (Dilantin)?

• A. Bladder palpation
• B. Inspection of the mouth
• C. Blood glucose monitoring
• D. Auscultation of breath sounds

Correct answer: B

Rationale: The correct answer is B: Inspection of the mouth. This assessment technique is crucial for monitoring gingival hyperplasia, a common side effect of phenytoin. Bladder palpation (choice A) is not relevant to monitoring for phenytoin's side effects. Blood glucose monitoring (choice C) is important for clients with diabetes but is not specifically related to phenytoin. Auscultation of breath sounds (choice D) is more relevant for assessing respiratory conditions, not side effects of phenytoin.

3. A client with diabetes mellitus reports feeling dizzy and has a blood glucose level of 50 mg/dl. What action should the nurse take first?

• A. Administer 1 mg of glucagon intramuscularly
• B. Provide 15 grams of carbohydrate
• C. Check the client's blood pressure
• D. Notify the healthcare provider

Correct answer: B

Rationale: Providing 15 grams of carbohydrate is the initial action to treat hypoglycemia. When a client with diabetes mellitus experiences symptoms of hypoglycemia, such as dizziness and with a blood glucose level of 50 mg/dl, the immediate priority is to raise their blood sugar levels quickly. Administering carbohydrates, such as fruit juice or glucose tablets, is the recommended first step to reverse hypoglycemia. Administering glucagon intramuscularly is usually reserved for severe hypoglycemia when the client is unconscious or unable to swallow. Checking the client's blood pressure is important but not the primary intervention for hypoglycemia. Notifying the healthcare provider can be done after the immediate management of hypoglycemia.

4. Which assessment finding should indicate to the nurse that a client with arterial hypertension is experiencing a cardiac complication?

• A. Complaints of an occipital headache
• B. A palpable dorsal pedis pulse bilaterally
• C. Complaints of shortness of breath on exertion
• D. A blood pressure of 160/90

Correct answer: C

Rationale: The correct answer is C, complaints of shortness of breath on exertion. This symptom is indicative of heart failure, a common cardiac complication of arterial hypertension. Shortness of breath on exertion is often due to the heart's inability to pump effectively, leading to fluid buildup in the lungs. Choices A, B, and D are incorrect because complaints of an occipital headache, a palpable dorsal pedis pulse bilaterally, and a blood pressure of 160/90 do not specifically indicate a cardiac complication in a client with arterial hypertension.

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.
