1. A client requests information on the use of Feverfew. Which of the following responses should the nurse make?

A. It is used to treat skin infections.
B. It can decrease the frequency of migraine headaches.
C. It can lessen nasal congestion in the common cold.
D. It can relieve nausea of morning sickness during pregnancy.

Correct answer: B

Rationale: The correct response is B: Feverfew is commonly used to decrease the frequency of migraine headaches. However, it is important to note that it has not been proven to relieve an existing migraine headache. Choices A, C, and D are incorrect as Feverfew is not typically used for treating skin infections, lessening nasal congestion in the common cold, or relieving nausea of morning sickness during pregnancy.

2. 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).

3. What is the antidote for Warfarin?

A. Naloxone
B. Vitamin K
C. Glucagon
D. Vitamin B

Correct answer: B

Rationale: The correct antidote for Warfarin is Vitamin K. Warfarin works by inhibiting vitamin K-dependent clotting factors. Administering Vitamin K helps reverse its effects by replenishing these factors. Choices A, C, and D are incorrect. Naloxone is used to reverse opioid overdose, Glucagon is used to treat severe low blood sugar, and Vitamin B is not the antidote for Warfarin.

4. What is the first type of medication prescribed to prevent angina pain for a client?

A. Beta blockers
B. Alpha blockers
C. Calcium channel blockers
D. Organic nitrates

Correct answer: A

Rationale: Beta blockers are the first-line medication prescribed to prevent angina pain. They work by reducing the heart rate and blood pressure, decreasing the heart's demand for oxygen. This helps in preventing angina attacks by improving blood flow to the heart. Alpha blockers, calcium channel blockers, and organic nitrates are also used in angina treatment but are typically considered after beta blockers.

5. In which of the following cases is Lansoprazole not used?

A. Gastritis
B. Peptic Ulcers
C. Zollinger-Ellison syndrome
D. Thalamus hypertrophy

Correct answer: D

Rationale: Lansoprazole is a proton pump inhibitor mainly used to treat conditions related to the stomach, such as gastritis, peptic ulcers, and Zollinger-Ellison syndrome. Thalamus hypertrophy is not a condition that Lansoprazole is indicated for; it is used for gastrointestinal issues and not neurological conditions.
