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 healthcare professional is reviewing the medical record of a client with a new prescription for Epoetin Alfa. Which of the following findings should the professional report to the provider?

A. The client has a history of hypertension.
B. The client has a hemoglobin level of 10 g/dL.
C. The client has a history of chronic kidney disease.
D. The client has a blood pressure of 140/90 mm Hg.

Correct answer: C

Rationale: The correct answer is C. Chronic kidney disease is a contraindication for the use of Epoetin Alfa because it can worsen hypertension, increase the risk of cardiovascular events, and lead to adverse outcomes. Epoetin Alfa is used to treat anemia by stimulating red blood cell production, but in the presence of chronic kidney disease, it can exacerbate hypertension and contribute to cardiovascular complications. Choices A, B, and D are not directly related to the contraindication of Epoetin Alfa in the presence of chronic kidney disease.

3. ACE Inhibitors are used in the treatment of all EXCEPT:

A. Hypertension
B. Heart Failure
C. Hypotension
D. Diabetic nephropathy

Correct answer: C

Rationale: ACE inhibitors are commonly used in the treatment of hypertension, heart failure, and diabetic nephropathy due to their ability to reduce blood pressure, improve heart function, and protect the kidneys. However, they are not indicated for hypotension as they can further lower blood pressure, worsening the condition. Therefore, the correct answer is C. Choice A, hypertension, is correct as ACE inhibitors are a first-line treatment for this condition. Choice B, heart failure, is also correct as ACE inhibitors help improve heart function in patients with heart failure. Choice D, diabetic nephropathy, is correct as ACE inhibitors can slow the progression of kidney damage in diabetic patients.

4. Which of the following is the antidote for Heparin toxicity?

A. Protamine
B. Methylene blue
C. N-acetylcysteine
D. Glucagon

Correct answer: A

Rationale: Protamine is the specific antidote for Heparin toxicity. Heparin is an anticoagulant medication, and if an overdose occurs or if there is excessive bleeding due to Heparin use, protamine, a positively charged molecule, can neutralize the anticoagulant effects of Heparin by forming a complex with it. This binding prevents Heparin from further inhibiting coagulation factors and helps in reversing its effects.

5. A nurse is providing discharge teaching to a client who has a new prescription for Warfarin. Which of the following statements should the nurse include?

A. You should avoid taking aspirin for headaches while on this medication.
B. You should use a soft toothbrush to brush your teeth.
C. You should avoid foods that are rich in vitamin K.
D. You should avoid prolonged exposure to sunlight.

Correct answer: B

Rationale: The correct statement to include in discharge teaching for a client prescribed Warfarin is to use a soft toothbrush to prevent gum bleeding. Warfarin is an anticoagulant that increases the risk of bleeding, so using a soft toothbrush can help prevent gum injury and bleeding. Choice A is incorrect because aspirin, another blood-thinning medication, should generally be avoided while on Warfarin to reduce the risk of bleeding. Choice C is incorrect because clients on Warfarin should maintain a consistent intake of vitamin K-rich foods rather than avoid them completely. Choice D is unrelated to the medication and not a priority teaching point for a client prescribed Warfarin.
