Nursing Elites

1. 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 inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

2. The nurse supervises care of a client who is receiving enteral feeding via a nasogastric tube. The nurse determines that care is appropriate if which of the following is observed? (Select all that apply)

• A. The nursing assistant aspirates and measures the amount of gastric aspirate
• B. The nursing assistant elevates the head of the client’s bed 30 degrees
• C. The nursing assistant warms the formula to room temperature
• D. B, C

Correct answer: D

Rationale: The correct answer is D because elevating the head of the bed reduces the risk of aspiration, and warming the formula to room temperature helps prevent discomfort and complications. Choice A is incorrect as only licensed healthcare professionals should aspirate and measure the amount of gastric aspirate. Choice B is correct as it helps prevent aspiration. Choice C is correct as warming the formula can prevent discomfort.

3. For a patient with a history of liver disease, which type of diet is most appropriate?

• A. High-protein
• B. High-carbohydrate
• C. Low-protein
• D. Low-fat

Correct answer: D

Rationale: A low-fat diet is the most appropriate for a patient with a history of liver disease. This diet helps reduce liver stress and manage symptoms associated with liver disease. High-protein and high-carbohydrate diets can strain the liver and worsen the condition. A low-protein diet may be necessary in cases of liver disease with hepatic encephalopathy, but in general, a low-fat diet is recommended to support liver function and overall health.

4. Interacting with the patient and their family to obtain subjective information is part of which of the following steps in determining and fulfilling the nursing care needs of the patient?

• A. Evaluation
• B. Planning
• C. Implementation
• D. Assessment

Correct answer: D

Rationale: The correct answer is D, Assessment. In the nursing process, assessment is the first step where nurses gather subjective and objective data to understand the patient's needs. Interacting with the patient and their family to obtain subjective information is crucial in this phase. Choice A, Evaluation, comes later in the process and involves judging the effectiveness of the care provided. Choice B, Planning, is where the nurse develops a plan of care based on the assessment findings. Choice C, Implementation, is the phase where the nursing care plan is put into action.

5. The nurse is aware that norepinephrine is secreted by which endocrine gland?

• A. The pancreas
• B. The adrenal cortex
• C. The adrenal medulla
• D. The anterior pituitary gland

Correct answer: C

Rationale: Norepinephrine is indeed secreted by the adrenal medulla, making choice C the correct answer. The adrenal medulla is part of the adrenal glands, located on top of the kidneys. Norepinephrine is involved in the body's 'fight or flight' response, helping to prepare the body to react to stress. Choices A, B, and D are incorrect as norepinephrine is not secreted by the pancreas, adrenal cortex, or the anterior pituitary gland.
