Urinary System Exam Questions Questions
Question 1 of 5
Aldosterone:
Correct Answer: B
Rationale: Aldosterone increases Na reabsorption e.g., distal tubule ENaC, raises BP. It's adrenal not JGA (renin triggers). K is secreted not reabsorbed. H secretion is separate pH effect indirect. Na reabsorption distinguishes it, key to volume control, unlike origin or ion errors.
Question 2 of 5
The nurse identifies a nursing diagnosis of risk for injury: fracture related to alterations in calcium and phosphorus metabolism for a patient with chronic renal disease. The pathologic process directly related to the risk for fractures is
Correct Answer: C
Rationale: Chronic renal disease impairs vitamin D activation, reducing calcium absorption, weakening bones not aluminum loss (dialysis issue), soft tissue calcification (secondary), or PTH alone (compensatory). This distinguishes hypocalcemia's skeletal impact, key for fracture risk, contrasting with other metabolic sequelae.
Question 3 of 5
A patient rapidly progressing toward end stage renal disease asks about the possibility of a kidney transplant. In responding to the patient, the nurse knows that contraindications to kidney transplantation include
Correct Answer: D
Rationale: Extensive vascular disease impairs graft perfusion, contraindicating transplant not hepatitis C (manageable), CAD (assessable), or hypertension (controllable). This distinguishes vascular viability, critical for transplant success, contrasting with treatable conditions.
Question 4 of 5
Diseases caused by E-coli are:
Correct Answer: D
Rationale: E. coli causes urinary tract infections (UTI, common), neonatal meningitis (via birth canal), and diarrhea (enteropathogenic strains) all apply. This broad pathogenicity distinguishes E. coli's clinical impact, critical for infectious disease, contrasting with limited scopes.
Question 5 of 5
For conversion of oxaloacetate to phosphoenol pyruvate, high energy molecule is required in the form of
Correct Answer: A
Rationale: Gluconeogenesis converts oxaloacetate to phosphoenolpyruvate using GTP specifically (PEPCK enzyme), not ATP or CTP. This distinguishes energy specificity, key for metabolic pathways, contrasting with broader nucleotide use.
