Answer to Question 1

Correct Answer: 1, 2, 3
For the serum creatinine level, assess the patient's medications because values may be affected by ascorbic acid, methyldopa, and lithium carbonate. Tetracycline and melatonin are not identified as affecting the serum creatinine level.

Answer to Question 2

Correct Answer: 1
The patient with a distended bladder experiences constant pain increased by any pressure over the bladder. Kidney pain is experienced in the back and the costovertebral angle (the angle between the lower ribs and adjacent vertebrae) and may spread toward the umbilicus. Renal colic (pain in response to renal calculi moving through the ureter) is severe, sharp, stabbing, and excruciating; often it is felt in the flank, bladder, urethra, testes, or ovaries. Bladder and urethral pain is usually dull and continuous but may be experienced as spasms.
