Warfarin (Coumadin) is an anticoagulant and interferes with the action of:
- A. Platelets
- B. Vitamin K
- C. Calcium
- D. Vitamin B12
Correct Answer: B
Rationale: The correct answer is B: Vitamin K. Warfarin works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.

- A. Treatment squad
- B. Area support squad
- C. Medical service squad
- D. Dental squad
Correct Answer: D

The other choices, A, B, and C, do not include the specific group of specialists mentioned in the question. Therefore, they are incorrect. The Treatment squad may involve a broader range of medical professionals, while the Area support squad and Medical service squad focus on different aspects of healthcare support not related to the dental field.
For a patient on lithium therapy, which dietary recommendation is essential?
- A. Increase caffeine intake
- B. Increase sodium intake
- C. Increase protein intake
- D. Increase fiber intake
Correct Answer: B
Rationale: The correct answer is to increase sodium intake. For patients on lithium therapy, maintaining consistent sodium intake is crucial to avoid fluctuations in drug levels. Increasing caffeine intake (choice A) is not recommended as it can interfere with lithium levels. While protein intake (choice C) is important for overall health, it is not specifically essential for patients on lithium therapy. Similarly, increasing fiber intake (choice D) is beneficial but not a primary concern for patients on lithium therapy.
The nurse is preparing a teaching care plan for the client diagnosed with nephritic syndrome. Which intervention should the nurse include?
- A. Discontinue the use of steroid therapy immediately if symptoms develop.
- B. Take diuretics as needed to treat the dependent edema in ankles.
- C. Increase the intake of dietary sodium every day to decrease fluid retention.
- D. Report any decrease in daily weight during treatment to the healthcare provider.
Correct Answer: D
Rationale: The correct answer is D. Reporting a decrease in daily weight is crucial when managing nephritic syndrome as it can indicate worsening of the condition or dehydration. It is essential to monitor weight changes closely to assess the effectiveness of treatment and the client's fluid status. Choice A is incorrect because discontinuing steroid therapy abruptly can lead to complications; gradual tapering is usually recommended. Choice B is incorrect as diuretics should be taken as prescribed by the healthcare provider to manage fluid retention. Choice C is also incorrect because increasing dietary sodium can exacerbate fluid retention, which is counterproductive in nephritic syndrome.
The nurse on the medical/surgical unit cares for a client with a diagnosis of cerebrovascular accident (CVA). The nursing assessment of the client's neurological status should include which of the following? (Select all that apply)
- A. Obtain the pulses in all four extremities
- B. Ask the client to grasp and squeeze two fingers on each of the nurse's hands
- C. Determine the client's orientation to person, place, and time
- D. B, C
Correct Answer: D
Rationale: The correct choices are B and C. Assessing grasp strength and orientation to person, place, and time are essential components of a neurological assessment after a CVA. Pulse assessment in all four extremities is more relevant to circulatory assessment rather than neurological status. Therefore, option A is incorrect.
