Question 5 Furosemide is a diuretic used in the treatment of congestive heart failure and oedema. 20 tablets of furosemide were powdered and 0.5195 g of powder was weighed out, shaken with 300 mL of NaOH and made up to 500 mL with 0.1 M NaOH. A portion of the extract was filtered and 5 mL of the filtrate was made up to 250 mL with 0.1 M NaOH. The absorbance of the diluted solution was measured at 271 nm. A (1%, 1 cm) value at 271 nm in basic solution Stated content of furosemide Weight of 20 tablets per tablet HN- From the data below calculate the percentage of stated content in a sample of furosemide tablets. (DGW 2005, 103) = 580 = 40 mg = 1,656 g OH NH

Question 79  You are caring for a client in hospital with an exacerbation of her severe COPD. The client states she is feeling very short of breath, she is agitated, and her respiratory rate is 36 breaths per minute.

Question 25 A normal person excretes 50% of the filtered urea. This occurs because: OA. Urea is actively transported into the nephron lumen against a concentration gradient OB. Urea is both absorbed and secreted in the nephron based on the passive gradient OC.Urea transporters use the sodium gradient to recycle urea back to the lumen of the PT

QUESTION 13 Two chambers, X and Y, are separated by a semi-permeable membrane that allows water and urea, but not glucose, to pass through. At the start, chamber X contains a solution of urea in wate and chamber Y contains a solution of glucose in water. The molarity (measure of concentration) of urea in chamber X is the same number as the molarity of glucose in chamber Y. Which of the following will occur after sufficient time? There will be overall diffusion of water from Y to X. There will be no overall diffusion of water across the membrane. There will be overall diffusion of water from X to Y.
