Question 1 of 5
Dr. Rodriguez orders 250 milliliters of packed red blood cells (RBC) for a patient. This therapy is administered for the treatment of:
Correct Answer: C
Rationale: Packed red blood cells (RBCs) are used to treat anemia, a condition characterized by a low red blood cell count or hemoglobin level. Anemia can result from blood loss, chronic disease, or nutritional deficiencies. Thrombocytopenia and leukopenia involve low platelet and white blood cell counts, respectively, and are not treated with RBC transfusions. Hypoalbuminemia involves low albumin levels and requires albumin infusions, not RBCs. Therefore, anemia is the correct indication for this therapy.

Question 3 of 5
Carbidopa when combined with levodopa:
Correct Answer: B
Rationale: Carbidopa enhances levodopa in Parkinson's. It inhibits peripheral (not cerebral) dopa decarboxylase, reducing levodopa breakdown outside the brain, allowing more to cross the blood-brain barrier. This reduces peripheral dopamine, minimizing nausea and hypotension, permitting lower levodopa doses, a true statement. It's compatible with warfarin, doesn't delay bradykinesia improvement (enhances onset), and doesn't abolish on-off effects (related to disease progression). Reduced side effects improve tolerability, a key therapeutic strategy.
Question 4 of 5
A 36-year-old woman grocery store manager with a fair complexion and blue eyes presents to her primary care physician for a routine exam. She mentions a friend of hers who is taking bimatoprost to increase the length and amount of her eyelashes and asks if you would recommend it for her. Her past medical history is significant for migraine headaches. Which of the following is a side effect you should warn her about?
Correct Answer: B
Rationale: Bimatoprost for eyelashes risks permanent iris darkening , increasing melanin, especially in light eyes. Glaucoma is its therapeutic use, not a side effect here. Stevens-Johnson , weight gain , and migraines (E) aren't linked. Darkening is a key cosmetic concern.
Question 5 of 5
A patient who takes high-dose aspirin to treat arthritis will need to take prednisone to treat an acute flare of symptoms. What action will the nurse perform?
Correct Answer: D
Rationale: Prednisone is a corticosteroid medication that can cause side effects such as fluid retention, electrolyte imbalance, and increased blood pressure. On the other hand, high-dose aspirin, especially when taken for arthritis, can have blood-thinning effects that may also contribute to lowering blood pressure. Given these potential effects of both medications, the nurse should be vigilant for the development of hypotension in the patient. Monitoring for signs and symptoms of low blood pressure, such as dizziness, lightheadedness, and weakness, is crucial in this situation to ensure the patient's safety.
