Lesson 1 Post Test
1. During the change-of-shift report the nurse states that a patient has early renal failure and that
you should be alert to this when administering medications. Why would this be a concern?
a) The kidneys assist in the detoxification of drug metabolites.
b) The patient may not be able to absorb all of the medications.
c) The bladder acts as a filter to remove wastes and form urine.
d) The kidneys are the primary site for drug metabolism.
Correct answer: a
Rationale: The kidneys detoxify and eliminate by products of drug metabolism. If the kidneys
are unable to perform this function, drug toxicity can develop. The nephron, the functional unit
of the kidney, forms the urine. The bladder holds the urine until it is excreted. The liver is a
primary site for drug metabolism.
2. Which of the following demonstrate that further teaching is required to prevent an infection
related to being catheterized? (Select all that apply.)
a) An elderly female carries her urinary drainage bag like a purse under her arm as she
ambulates.
b) A patient drinks an entire pitcher of water over the period of one day.
c) As a patient is being transferred in a wheelchair, he places the drainage bag in his lap.
d) The NAP places a patient’s drainage bag on a lowered side rail or on the floor.
e) A female patient keeps her catheter secured to her thigh with tape.
Correct answer: a, c, d
Rationale: The urinary drainage bag should be kept below the level of the bladder to prevent
reflux of urine into the bladder. Patients should be instructed to carry the drainage bag below the
level of the bladde, and to secure the drainage bag to the side of the wheelchair below the level
of the bladder during transfer. The urinary drainage bag should never be placed on a bedside rail
because it could accidentally be raised to a height higher than the level of the bladder and urine
could reflux into the bladder. The urinary drainage bag should never be placed on the floor; this
is to avoid having bacteria enter the system through the drainage port. If allowed, fluids should
be encouraged. The catheter should be secured to the patient in order to prevent trauma to the
urethra. Swelling of tissues can impair urine flow and place the patient at further risk for urinary
tract infection.
3. Which of the following is (are) true regarding the impact of aging related to urinary
elimination? (Select all that apply.)
a) The elderly are better able to concentrate urine than the middle-aged adult. [Show Less]
