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. The nurse is caring for a client with a history of deep vein thrombosis (DVT) who is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Prothrombin time (PT) is monitored to ensure therapeutic levels of warfarin and prevent bleeding complications.

3. A 50-year-old man presents with fatigue, arthralgia, and darkening of the skin. Laboratory tests reveal elevated liver enzymes and high serum ferritin levels. What is the most likely diagnosis?

• A. Wilson's disease
• B. Hemochromatosis
• C. Alpha-1 antitrypsin deficiency
• D. Autoimmune hepatitis

Correct answer: B

Rationale: The symptoms of fatigue, arthralgia, and skin darkening, along with elevated liver enzymes and high serum ferritin levels, are characteristic of hemochromatosis, a condition characterized by iron overload. In hemochromatosis, excess iron is deposited in various organs, including the liver, leading to symptoms such as fatigue, joint pain, and skin pigmentation changes. The elevated liver enzymes and high serum ferritin levels seen in this patient further support the diagnosis of hemochromatosis.

4. A patient with glaucoma is prescribed timolol eye drops. What is the primary action of this medication?

• A. Reduce intraocular pressure
• B. Dilate the pupils
• C. Constrict the pupils
• D. Enhance tear production

Correct answer: A

Rationale: Timolol eye drops are prescribed to reduce intraocular pressure in patients with glaucoma. By decreasing the pressure within the eye, timolol helps prevent damage to the optic nerve, which is crucial in managing glaucoma and preserving vision. Dilating or constricting the pupils or enhancing tear production are not the primary actions of timolol eye drops.

5. The community mental health nurse is planning to visit four clients with schizophrenia today. Which client should the nurse see first?

• A. The mother who took her children from school because aliens were after them.
• B. The young man who has a history of substance abuse and no telephone.
• C. The newly diagnosed client who needs to be evaluated for medication compliance.
• D. The young woman who believes she is to blame for her recent miscarriage.

Correct answer: A

Rationale: The mother who took her children from school due to delusions of aliens poses a significant risk to her children and herself. This situation requires immediate attention to ensure the safety and well-being of all involved. Choice B is concerning due to the history of substance abuse, but the immediate risk to life and safety as in Choice A takes precedence. Choice C, although important, does not present an immediate danger as the delusional belief of aliens. Choice D, while emotionally distressing, does not pose an immediate threat as the situation described in Choice A.
