Multiple Choice Questions On Urinary System Questions
Question 1 of 5
Signs and symptoms of acute rejection that the nurse should teach the patient to observe for include
Correct Answer: B
Rationale: Acute rejection presents with fever and graft tenderness from immune attack not tachycardia (nonspecific), hypotension (shock), or infections (complications). This distinguishes acute rejection signs, critical for patient education, contrasting with systemic or infectious issues.
Question 2 of 5
A 7-year old boy suffers from mental retardation and self-mutilation and has increased levels of serum uric acid. These symptoms are characteristic of Lesch-Nyhan syndrome, which is due to defective
Correct Answer: D
Rationale: Lesch-Nyhan syndrome results from HGPRT deficiency, impairing purine salvage, raising uric acid not pyrimidine pathways or xanthine oxidase. This distinguishes purine metabolism defects, critical for neurologic/renal symptoms, contrasting with other enzymes.
Question 3 of 5
Concerning podocytes all of the followings are true EXCEPT:
Correct Answer: D
Rationale: Podocytes have processes, filaments, and form the filtration barrier not part of the juxtaglomerular apparatus (macula densa, JG cells). This distinguishes podocyte function, critical for filtration, contrasting with JGA regulation.
Question 4 of 5
Which one of the following compounds cannot give rise to the net synthesis of Glucose?
Correct Answer: B
Rationale: Gluconeogenesis uses lactate, α-ketoglutarate, and glycerol not acetyl CoA (enters Krebs, no net glucose). This distinguishes gluconeogenic substrates, key for fasting metabolism, contrasting with irreversible pathways.
Question 5 of 5
The first line medical treatment for prevention of Cystine stones is
Correct Answer: C
Rationale: Increasing cystine solubility (e.g., via alkalinization, fluids) is first-line for cystine stones raises pH above 7, reducing precipitation. Acidification worsens solubility opposite effect. Lowering sodium aids calcium stones, not cystine irrelevant. Intestinal binding isn't a strategy cystine is renal. Solubility enhancement distinguishes cystine prevention, key to managing this genetic defect, unlike counterproductive, unrelated, or non-existent approaches.
