A nurse is providing education about the common causes of polyuria to a client who has a urinary alteration. Which of the following client statements indicates an understanding of the teaching?
"Polyuria can be caused by using antidepressants."
"Polyuria can be caused by enlargement of the prostate gland."
"Polyuria can be caused by drinking too much fluid."
"Polyuria can be caused by trauma to the lower urinary tract."
The Correct Answer is C
A. "Polyuria can be caused by using antidepressants.": Antidepressants are more commonly associated with urinary retention or hesitancy rather than polyuria, so this statement reflects a misunderstanding of the typical causes.
B. "Polyuria can be caused by enlargement of the prostate gland.": Prostate enlargement usually causes urinary retention, difficulty initiating urination, or nocturia, rather than excessive urine output.
C. "Polyuria can be caused by drinking too much fluid.": Excessive fluid intake increases urine production, which is a common and direct cause of polyuria. This reflects an accurate understanding of one of the typical mechanisms leading to increased urine output.
D. "Polyuria can be caused by trauma to the lower urinary tract.": Trauma is more likely to result in hematuria, pain, or retention, not necessarily polyuria. This statement does not accurately reflect a common cause of excessive urination.

Correct Answer is ["2.5"]
Explanation
Calculation:
Desired dose = 20 mg.
Available concentration = 40 mg / 5 mL
= 8 mg/mL.
- Calculate the volume to administer in milliliters (mL).
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 20 mg / 8 mg/mL
= 2.5 mL.
Correct Answer is C
Explanation
Rationale:
A. A blister-like area: Blistering is not the expected reaction used to interpret a Mantoux test. The result is based on the presence and size of induration, not the formation of blisters.
B. A cool, blanched area: Coolness and blanching are not indicators of a positive test. These findings may reflect poor circulation or local skin reaction unrelated to tuberculosis screening.
C. An elevated, hardened area: Induration (elevated, firm area) at the injection site, measured in millimeters, is the basis for determining a positive result. The size threshold for positivity depends on the client’s risk factors for tuberculosis.
D. An area of ecchymosis: Bruising at the site is a local skin reaction that can occur after any injection and is unrelated to the diagnostic criteria for a positive Mantoux test.
