The nurse is conducting medication education about the difference between potency and efficacy to a group of patients. The nurse correctly determines that learning has occurred when the patients make which response?

Correct Answer: B

Rationale: Efficacy (max effect) trumps potency (dose needed) for ‘best'-a high-efficacy drug fully relieves symptoms, unlike high-potency alone. Potency doesn't guarantee outcome. Efficacy doesn't mean fewer side effects-safety varies. Low-potency drugs can be effective but aren't side-effect-free. Greatest efficacy reflects learning, prioritizing treatment success.

Correct Answer: A

Rationale: Furosemide, a loop diuretic, can rarely lead to a serious adverse reaction known as Stevens-Johnson syndrome. Stevens-Johnson syndrome is a severe skin reaction that can be life-threatening and typically involves painful blistering and shedding of the skin. This reaction is considered a serious medical emergency and requires immediate medical attention. It is crucial to monitor for any signs of skin changes or reactions while using Furosemide and report them to a healthcare provider promptly.

Correct Answer: D

Rationale: Myeloablation refers to the destruction of bone marrow, which is a critical step in preparing a patient for a bone marrow or stem cell transplant. This process eliminates both cancerous and healthy bone marrow cells, creating space for the transplanted cells to engraft and repopulate the marrow. While myeloablation can reduce tumor size, its primary purpose is to prepare the body for transplantation. It is not related to destroying muscle cells or reducing postoperative chemotherapy requirements.

Correct Answer: C

Rationale: The therapeutic range for Lithium is typically considered to be 0.6-1.2 mEq/L for maintenance treatment. However, some sources may also suggest a wider therapeutic range of 0.5-2 mEq/L. Monitoring serum lithium levels is crucial to ensure that the patient is within the therapeutic range and to adjust the dosage accordingly to avoid toxicity or subtherapeutic levels. Thus, option C (0.5-2) provides a more comprehensive and inclusive range that is commonly referenced in clinical practice.

Correct Answer: A

Rationale: The reticular activating system (RAS) in the brainstem regulates sleep-wake cycles, promoting alertness or rest, per neurophysiology. The cortex processes thought, not cycles. The limbic system drives emotion, not sleep directly. The cerebellum coordinates movement. RAS's role is central, controlling consciousness states.
