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. A client with type 1 diabetes is diagnosed with diabetic ketoacidosis and initially treated with intravenous fluids followed by an IV bolus of regular insulin. The nurse anticipates that the practitioner will prescribe a continuous infusion of insulin of:

• A. Novolin L insulin
• B. Novolin R insulin
• C. Novolin N insulin
• D. Novolin U insulin

Correct answer: B

Rationale: The correct answer is Novolin R (Regular insulin). Regular insulin is used for continuous infusion to treat diabetic ketoacidosis due to its rapid onset of action. Novolin L (Intermediate-acting insulin) (choice A), Novolin N (Intermediate-acting insulin) (choice C), and Novolin U (Ultra-Long-acting insulin) (choice D) are not suitable for continuous infusion in the treatment of diabetic ketoacidosis.

3. The type of lipoprotein that carries cholesterol from tissues to the liver for excretion is:

• A. Very low-density lipoprotein
• B. Intermediate-density lipoprotein
• C. Low-density lipoprotein
• D. High-density lipoprotein

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as the 'good' cholesterol and plays a crucial role in transporting cholesterol from tissues back to the liver for excretion. This process helps in reducing the buildup of cholesterol in the bloodstream, thus lowering the risk of heart diseases. Very low-density lipoprotein (Option A), Intermediate-density lipoprotein (Option B), and Low-density lipoprotein (Option C) are not responsible for carrying cholesterol back to the liver for excretion like HDL does. Instead, they are associated with different functions related to cholesterol transportation within the body.

4. The client has recently been diagnosed with irritable bowel syndrome (IBS). Which intervention should the nurse teach the client to reduce symptoms?

• A. Instruct the client to avoid drinking fluids with meals
• B. Explain the need to decrease intake of flatus-forming foods
• C. Teach the client how to perform gentle perianal care
• D. Encourage the client to see a psychologist

Correct answer: B

Rationale: Choosing option B, explaining the need to decrease intake of flatus-forming foods, is the correct intervention to reduce IBS symptoms. Flatus-forming foods can worsen bloating and discomfort in individuals with IBS. Option A, instructing the client to avoid drinking fluids with meals, may be helpful for other conditions but is not a primary intervention for IBS. Option C, teaching perianal care, is not directly related to reducing IBS symptoms. Option D, encouraging the client to see a psychologist, may be beneficial for managing stress related to IBS but is not the initial intervention to reduce symptoms.

5. Performing and supervising therapeutic and preventive procedures that have been planned for a patient is part of which of the following steps for determining and fulfilling the nursing care needs of the patient?

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

Correct answer: C

Rationale: The correct answer is C: Implementation. Implementation in nursing care involves the actual performance and supervision of the planned therapeutic and preventive procedures for a patient. Evaluation (choice A) is the step where the effectiveness of the interventions is assessed. Planning (choice B) is the phase where the nursing care plan is developed based on the assessment. Assessment (choice D) is the initial step in the nursing process, involving data collection and analysis to determine the patient's needs.
