1. What is the primary use of lithium?

A. Lower blood glucose
B. Slow the heart rate
C. Stabilize mood
D. Heal ulcers

Correct answer: C

Rationale: The correct answer is C: Stabilize mood. Lithium is primarily used to stabilize mood, especially in conditions like bipolar disorder. It helps in reducing the frequency and severity of manic episodes, making it an essential medication for mood stabilization. Choices A, B, and D are incorrect as lithium is not used to lower blood glucose, slow the heart rate, or heal ulcers.

2. A client has a prescription for Amoxicillin. Which of the following instructions should be included?

A. Take the medication with food.
B. Avoid taking the medication with milk.
C. Expect your stools to turn clay-colored.
D. Complete the entire course of therapy.

Correct answer: D

Rationale: The correct answer is D: Complete the entire course of therapy. It is crucial for clients to complete the entire course of amoxicillin therapy to ensure the infection is fully treated and to prevent antibiotic resistance. Prematurely stopping the antibiotic can lead to incomplete eradication of the infection, potentially causing it to return and be more difficult to treat. Choices A and B are not specific to amoxicillin and are general medication administration instructions. Choice C is not a common side effect of amoxicillin and does not require patient education.

3. A client has been prescribed Warfarin for atrial fibrillation. Which of the following instructions should the nurse include in the discharge teaching?

A. Avoid foods high in vitamin K.
B. Take this medication with food to prevent nausea.
C. Monitor your heart rate daily before taking the medication.
D. Limit your fluid intake to 1 liter per day.

Correct answer: A

Rationale: The correct instruction for the nurse to include in the discharge teaching for a client prescribed Warfarin is to 'Avoid foods high in vitamin K.' Foods high in vitamin K can decrease the effectiveness of Warfarin by interfering with its anticoagulant effects, potentially leading to blood clotting issues. It is crucial for clients on Warfarin therapy to maintain a consistent intake of vitamin K-containing foods to ensure the stability of the medication's effects. Choices B, C, and D are incorrect because taking Warfarin with food, monitoring heart rate daily, or limiting fluid intake are not directly related to optimizing the effectiveness of Warfarin therapy.

4. A healthcare provider is preparing to administer a transfusion of a unit of packed red blood cells (PRBCs) for a client who has severe anemia. Which of the following interventions will prevent an acute hemolytic reaction?

A. Ensure that the client has a patent IV line before obtaining the blood product from the refrigerator.
B. Obtain help from another healthcare provider to confirm the correct client and blood product.
C. Take a complete set of vital signs before beginning the transfusion and periodically during the transfusion.
D. Stay with the client for the first 15 to 30 minutes of the transfusion.

Correct answer: B

Rationale: The correct answer is to obtain help from another healthcare provider to confirm the correct client and blood product. This action is crucial in preventing an acute hemolytic reaction, which is caused by ABO or Rh incompatibility. Verifying the correct client and blood product before the transfusion ensures that there are no errors in identification, reducing the risk of a potentially life-threatening reaction. Choices A, C, and D are important aspects of transfusion safety but are not directly related to preventing acute hemolytic reactions. Ensuring a patent IV line, monitoring vital signs, and staying with the client are all essential during transfusion but do not specifically address the risk of ABO or Rh incompatibility reactions.

5. Which medication is contraindicated with Nitroglycerin?

A. Hydrochloroquine
B. Methylprednisolone
C. Phenazopyridine
D. Erectile dysfunction drugs

Correct answer: D

Rationale: The correct answer is D: Erectile dysfunction drugs. Erectile dysfunction drugs are contraindicated with Nitroglycerin because they can potentiate the hypotensive effects of Nitroglycerin, leading to severe hypotension. Choices A, B, and C are incorrect because they are not known to have significant interactions with Nitroglycerin.
