Nursing Elites

1. A patient with severe anemia is prescribed erythropoietin. What is the primary action of this medication?

• A. Stimulate white blood cell production
• B. Increase platelet count
• C. Promote red blood cell production
• D. Enhance clotting factor production

Correct answer: C

Rationale: Erythropoietin is a hormone that primarily stimulates the bone marrow to produce more red blood cells. By increasing red blood cell production, erythropoietin helps to improve oxygen delivery to tissues, which is essential in managing anemia. Choices A, B, and D are incorrect because erythropoietin specifically targets red blood cell production and does not have a direct effect on white blood cells, platelets, or clotting factors.

2. A patient with tuberculosis is started on rifampin. What advice should the nurse provide?

• A. Limit intake of green leafy vegetables.
• B. Expect orange-red discoloration of body fluids.
• C. Avoid exposure to sunlight.
• D. Take the medication with antacids.

Correct answer: B

Rationale: The correct advice for a patient starting rifampin is to expect orange-red discoloration of body fluids. Rifampin can cause harmless orange-red discoloration of body fluids, which may include urine, sweat, saliva, and tears. It is important for the patient to be aware of this side effect as it can stain clothing and contact lenses. Limiting the intake of green leafy vegetables is not necessary with rifampin. Avoiding exposure to sunlight is more commonly associated with other medications like tetracyclines, not rifampin. Taking rifampin with antacids is not recommended as antacids can reduce the absorption of rifampin, decreasing its effectiveness in treating tuberculosis.

3. The healthcare provider is assessing a client with Cushing's syndrome. Which clinical manifestation should the healthcare provider expect to find?

• A. Hyperpigmentation of the skin.
• B. Hypotension.
• C. Moon face and buffalo hump.
• D. Weight loss.

Correct answer: C

Rationale: The correct answer is C: Moon face and buffalo hump. In Cushing's syndrome, excess production of corticosteroids leads to redistribution of fat, particularly in the face (moon face) and between the shoulders (buffalo hump). Hyperpigmentation of the skin is actually associated with Addison's disease, not Cushing's syndrome (choice A). Hypotension is not a typical finding in Cushing's syndrome; instead, hypertension is more commonly seen due to the effects of excess cortisol (choice B). Weight gain, rather than weight loss, is a common symptom of Cushing's syndrome due to the metabolic disturbances caused by excess cortisol (choice D).

4. A patient with a diagnosis of peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?

• A. With meals
• B. At bedtime
• C. Before meals
• D. After meals

Correct answer: C

Rationale: Omeprazole is best taken before meals for optimal effectiveness in reducing stomach acid production and promoting ulcer healing. Taking it before meals allows the medication to act on the proton pumps before food intake triggers acid production, thereby maximizing its therapeutic benefits. Choices A, B, and D are incorrect because taking omeprazole with meals, at bedtime, or after meals may not align with its mechanism of action, potentially reducing its effectiveness in managing peptic ulcer disease.

5. A client with a new diagnosis of diabetes mellitus is learning to self-administer insulin. Which instruction should the nurse include?

• A. Store the insulin in the freezer.
• B. Administer the insulin at the same site each time.
• C. Rotate injection sites within the same region.
• D. Shake the vial vigorously before drawing up the insulin.

Correct answer: C

Rationale: The correct instruction for a client learning to self-administer insulin is to rotate injection sites within the same region. This practice helps prevent lipodystrophy, which is a condition characterized by fat tissue changes due to repeated injections in the same spot, and also ensures consistent absorption of insulin throughout the body. Storing insulin in the freezer is incorrect as it can lead to denaturation of the insulin. Administering the insulin at the same site each time can cause lipodystrophy and inconsistent absorption. Shaking the vial vigorously before drawing up the insulin is also incorrect as it can lead to insulin degradation.
