Renal System Questions Quizlet Questions
Question 1 of 5
Concerning the functional histology of the kidney:
Correct Answer: D
Rationale: Superficial nephrons with short loops (A) reabsorb less salt, deep nephrons with long loops (B) enhance salt and water reabsorption via countercurrent mechanisms, and in dehydration (C), blood shifts to deep nephrons to maximize concentration. All are correct: short loops limit salt reabsorption, long loops boost it, and dehydration favors deep nephrons, making E (all are correct), reassigned as D, the answer.
Question 2 of 5
The appearance of glucose in the urine:
Correct Answer: D
Rationale: Glucose appears in urine (glycosuria) when its plasma level exceeds the renal threshold (~180 mg/dL), saturating PCT carriers (D). It's not normal (A), unrelated to angiotensin II (B), and hypoglycemia (C) reduces glucose, making D the cause.
Question 3 of 5
Podocytes make up the:
Correct Answer: D
Rationale: Podocytes form the visceral layer of Bowman's capsule (D), surrounding glomerular capillaries to filter plasma. Nephron (A) is broader, glomerulus (B) is capillaries, and renal capsule (C) is outer, making D precise.
Question 4 of 5
Which of the following is found in the renal medulla?
Correct Answer: D
Rationale: The loop of Henle (D) extends into the renal medulla, aiding concentration. Pacemaker cells (A) are cardiac, islets (B) are pancreatic, and DCT (C) is cortical, making D the medullary structure.
Question 5 of 5
A 62-year-old asks the nurse for a perineal pad, stating that laughing or coughing causes leakage of urine. Which intervention is most appropriate to include in the care plan?
Correct Answer: D
Rationale: Stress incontinence from coughing/laughing improves with Kegel exercises (D) to strengthen pelvic muscles. Toileting (A) or commode (B) suits functional incontinence, and Credé (C) is for overflow, making D most appropriate.
