Nursing Elites

1. What is the therapeutic use of metformin?

• A. Lower blood pressure
• B. Diminish seizure activity
• C. The maintenance of a person's blood glucose levels
• D. Increase heart rate and decrease gastrointestinal secretions

Correct answer: C

Rationale: Metformin is commonly prescribed to manage and control blood glucose levels in individuals with diabetes. It helps in reducing the amount of glucose produced by the liver and improves the body's response to insulin, thereby aiding in the regulation of blood sugar levels. It is not used to lower blood pressure, diminish seizure activity, increase heart rate, or decrease gastrointestinal secretions.

2. When teaching a client about a new prescription for Celecoxib, which of the following information should the nurse include?

• A. Increases the risk for a myocardial infarction
• B. Decreases the risk of stroke
• C. Inhibits COX-1
• D. Increases platelet aggregation

Correct answer: A

Rationale: The nurse should educate the client that taking Celecoxib increases the risk of a myocardial infarction due to its suppression of vasodilation. Celecoxib belongs to the class of NSAIDs known to have cardiovascular risks, including an increased risk of heart attacks. Choice B is incorrect because Celecoxib does not decrease the risk of stroke. Choice C is incorrect because Celecoxib selectively inhibits COX-2 rather than COX-1. Choice D is incorrect because Celecoxib does not increase platelet aggregation; in fact, it inhibits platelet aggregation.

3. A client has a new prescription for Warfarin. Which of the following statements should the nurse include in the teaching?

• A. You will need to have your blood tested regularly while taking this medication.
• B. It is safe to take over-the-counter NSAIDs with this medication.
• C. You will need to avoid foods high in vitamin K while taking this medication.
• D. You will need to take this medication with food.

Correct answer: C

Rationale: Warfarin interacts with vitamin K, so clients should be instructed to avoid foods high in vitamin K. This is because vitamin K can interfere with the anticoagulant effects of Warfarin. It is important to maintain a consistent intake of vitamin K-containing foods to keep the medication working effectively. Therefore, the correct statement for the nurse to include in the teaching is to advise the client to avoid foods high in vitamin K while taking Warfarin. Choices A, B, and D are incorrect. Regular blood testing is necessary with Warfarin to monitor its effects and adjust the dosage if needed (Choice A). Taking over-the-counter NSAIDs with Warfarin is not safe due to an increased risk of bleeding (Choice B). Warfarin can be taken with or without food, so there is no specific requirement to take it with food (Choice D).

4. What is the antidote for Heparin?

• A. Protamine sulfate
• B. Vitamin K
• C. Naloxone
• D. Toradol

Correct answer: A

Rationale: The correct answer is A: Protamine sulfate. Heparin is an anticoagulant that prevents blood clotting. Protamine sulfate is the antidote for Heparin as it binds to heparin, neutralizing its anticoagulant effects. Vitamin K is not the antidote for Heparin; it is used to reverse the effects of warfarin, another anticoagulant. Naloxone is an opioid antagonist for opioids, and Toradol is a nonsteroidal anti-inflammatory drug (NSAID) for pain relief. Therefore, the correct antidote for Heparin is Protamine sulfate.

5. A client has a new prescription for Omeprazole. Which of the following instructions should the nurse include?

• A. Take this medication before meals.
• B. Take this medication with food.
• C. Take this medication at bedtime.
• D. Take this medication with antacids.

Correct answer: A

Rationale: The correct answer is A: 'Take this medication before meals.' Omeprazole is a proton pump inhibitor that is most effective in reducing stomach acid production when taken before meals. This timing helps the medication work optimally by inhibiting acid secretion that occurs in response to food intake. Choice B ('Take this medication with food') is incorrect because Omeprazole should be taken before meals. Choice C ('Take this medication at bedtime') is incorrect as the optimal timing is before meals, not at bedtime. Choice D ('Take this medication with antacids') is incorrect because Omeprazole should not be taken with antacids as they can interfere with its absorption.
