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. One of the reasons hospital patients are at greater risk for drug-nutrient interactions than they used to be is because:

• A. Hospitalized patients are more acutely ill
• B. Hospital routines interfere with the correct timing of medications
• C. Drugs used today are more toxic and have more side effects
• D. Responsibility for monitoring this is shared by various members of the healthcare team

Correct answer: A

Rationale: The correct answer is A. Hospitalized patients are more acutely ill, often having multiple conditions and treatments, which increases the risk of drug-nutrient interactions. Choice B is incorrect because hospital routines do not specifically interfere with the timing of medications in relation to drug-nutrient interactions. Choice C is incorrect because the toxicity and side effects of drugs do not directly relate to an increased risk of drug-nutrient interactions. Choice D is incorrect as sharing responsibility for monitoring does not inherently increase the risk of drug-nutrient interactions in hospital patients.

3. 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 answer is 'D' because assessing grasp strength (choice B) and orientation to person, place, and time (choice C) are crucial components of a neurological assessment following a cerebrovascular accident (CVA). Pulse assessment in all four extremities (choice A) is not directly related to a neurological assessment and is more pertinent to vascular status. Therefore, choices A and D are incorrect in this context.

4. The client is complaining of painful swallowing secondary to mouth ulcers. Which statement by the client indicates appropriate management?

• A. “I will brush my teeth with a soft-bristle toothbrush.”
• B. “I will rinse my mouth with Listerine mouthwash.”
• C. “I will swish my antifungal solution and then swallow.”
• D. “I will avoid spicy foods, tobacco, and alcohol.”

Correct answer: D

Rationale: The correct answer is D. Avoiding irritants like spicy foods, tobacco, and alcohol is crucial in managing mouth ulcers as they can further irritate the ulcers and delay healing. Choices A, B, and C could potentially worsen the condition. Brushing with a soft-bristle toothbrush may cause discomfort, rinsing with Listerine mouthwash can be too harsh on the ulcers, and swallowing antifungal solution is not recommended unless specified by a healthcare provider.

5. A client is ordered lisinopril (Zestril) for the treatment of hypertension. He asks the nurse about possible adverse effects. The nurse should inform him about which common adverse effects of angiotensin-converting enzyme (ACE) inhibitors?

• A. Constipation
• B. Dizziness
• C. Headache
• D. B, C

Correct answer: D

Rationale: The correct answer is D: 'B, C.' Dizziness and headache are common side effects of ACE inhibitors due to their blood pressure-lowering effects. Constipation is not a common adverse effect associated with ACE inhibitors, so choice A is incorrect. Choice B (Dizziness) and choice C (Headache) are more commonly seen and are directly related to the mechanism of action of ACE inhibitors, making them the correct choices.
