A patient is prescribed a high-alert medication that requires independent double-checking before administration. Which of the following medications is MOST likely to fall into this category?
सही उत्तर: ख) B) Morphine

An elderly client with type 2 diabetes is taking a non-selective beta-blocker. The nurse notes the client's blood glucose levels are consistently elevated despite dietary adjustments and increased insulin doses. Why is this occurring?
सही उत्तर: ग) C) The beta-blocker decreases glycogenolysis and gluconeogenesis, resulting in elevated blood glucose levels.
The correct answer is C. Non-selective beta-blockers inhibit the effects of catecholamines (epinephrine and norepinephrine) on the liver, which normally stimulates glycogenolysis and gluconeogenesis – processes that raise blood glucose. This results in a failure to adequately control blood sugar levels.

यदि 500 एमएल घोलमा 25,000 युनिट हेपरिन छ, र दर 1,000 युनिट प्रति घण्टा तय गरिएको छ भने, पम्पको सेट दर (मिली/घण्टा) कस्तो हुनुपर्छ?
सही उत्तर: ख) 20
हेपरिनको सांद्रता 25,000/500 = 50 युनिट/मिली हुन्छ। त्यसैले, 1,000 युनिट/घण्टाको दर प्राप्त गर्न 1,000/50 = 20 मिली/घण्टा सेट गर्नुपर्छ।
