Renal System Questions and Answers Questions
Question 1 of 5
Renin
Correct Answer: C
Rationale: Renin catalyzes angiotensinogen to angiotensin I, leading to angiotensin II (C), which increases sodium reabsorption and vasoconstriction. It doesn't directly affect water (A), decrease sodium (B), or directly increase sodium (D), making C the primary effect.
Question 2 of 5
Incontinence refers to the inability to control micturition
Correct Answer: A
Rationale: Incontinence is the involuntary loss of bladder control (A), impairing micturition regulation, a true clinical definition. False (B) would deny this standard meaning, making A correct.
Question 3 of 5
True or False: The significant presence of red blood cells in the urine is normal and healthy
Correct Answer: B
Rationale: Red blood cells in urine (hematuria) indicate pathology (e.g., infection, stones), not normal health (B). True (A) contradicts this clinical sign, making False correct.
Question 4 of 5
A 32-year-old patient is diagnosed with polycystic kidney disease. Which information is most appropriate for the nurse to include in teaching at this time?
Correct Answer: A
Rationale: At 32, genetic counseling (A) is vital for polycystic kidney disease (autosomal dominant) due to reproductive implications. Transplantation (B), pain (C), and dialysis (D) are later concerns, making A most relevant now.
Question 5 of 5
Following an open loop resection and fulguration of the bladder, a patient is unable to void. Which nursing action should be implemented first?
Correct Answer: B
Rationale: A sitz bath (B) relaxes perineal muscles post-surgery, promoting voiding as the first non-invasive step. Catheterization (A) risks UTI, fluids (C) don't address retention, and exercises (D) are preventive, making B the initial action.
