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.

What is the initial step in providing healthcare for a patient?
- A. Obtain and interpret vital signs
- B. Determine the needs of the patient
- C. Develop a plan of care
- D. Obtain lab work and x-rays
Correct Answer: B
Rationale: The initial step in providing healthcare for a patient is to determine the needs of the patient. This step involves assessing the patient's condition, listening to their concerns, and understanding what care or treatment they require. Obtaining and interpreting vital signs (Choice A) is a crucial step but typically follows the assessment of the patient's needs. Developing a plan of care (Choice C) and obtaining lab work and x-rays (Choice D) come after understanding the patient's needs and assessing their condition.
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 intervention for the nurse to include in the care plan for a client diagnosed with nephritic syndrome is to instruct the client to report any decrease in daily weight during treatment to the healthcare provider. A decrease in weight could indicate worsening of the nephritic syndrome or dehydration, making it crucial information for the healthcare provider to assess the client's condition. Option A is incorrect because discontinuing steroid therapy should be done under medical guidance rather than immediately if symptoms develop. Option B is incorrect because diuretics should not be taken without healthcare provider's guidance due to the risk of electrolyte imbalances. Option C is incorrect as increasing dietary sodium would exacerbate fluid retention, which is undesirable in nephritic syndrome.
The nurse is caring for a client in a sickle cell crisis. Which is the pain regimen of choice to relieve the pain?
- A. Frequent aspirin (acetylsalicylic acid) and a non-narcotic analgesic
- B. Motrin (ibuprofen), an NSAID, PRN
- C. Demerol (meperidine), a narcotic analgesic, every four (4) hours
- D. Morphine, a narcotic analgesic, every two (2) to three (3) hours PRN
Correct Answer: D
Rationale: In a sickle cell crisis, morphine is the preferred analgesic due to its potency and effectiveness in managing severe pain. Choice A is incorrect because aspirin is contraindicated in sickle cell disease due to its potential to cause a further decrease in blood flow. Choice B, Motrin (ibuprofen), is also not the ideal choice as NSAIDs can exacerbate renal complications in sickle cell patients. Choice C, Demerol (meperidine), is not recommended for sickle cell pain management due to its toxic metabolite accumulation which can cause seizures and other complications.
What is the FIRST step in providing health care for a patient?
- A. Obtain and interpret vital signs
- B. Determine the needs of the patient
- C. Develop a plan of care
- D. Obtain lab work and x-rays
Correct Answer: B
Rationale: The correct first step in providing health care for a patient is to determine the needs of the patient. Understanding the patient's requirements, concerns, and medical history is crucial before proceeding with any further steps. Option A, 'Obtain and interpret vital signs,' may be necessary but typically follows assessing the patient's needs. Option C, 'Develop a plan of care,' comes after identifying the patient's needs. Option D, 'Obtain lab work and x-rays,' is usually done based on the patient's needs and the developed plan of care, making it a later step in the process.
