Tested questions with rationales from the
NUR 5461 Module 7 Quiz at William
Paterson University.
Covers Advanced Pathophysiology core
concepts.
Reflects actual quiz format. Ideal for exam preparation
and concept mastery.
, 7.1 What is the function of osteocalcin?
A. Forms compression-resistant networks between collagen fibrils
B. Controls collagen interactions that lead to fibril formation
C. Plays a part in bone resorption by recruiting osteoclasts
D. Transports essential elements such as hormones
Answer: C. Plays a part in bone resorption by recruiting osteoclasts
Expert Rationale: Osteocalcin (bone Gla protein) is a non-collagenous protein
made by osteoblasts that binds calcium and is inṿolṿed in bone turnoṿer. It helps
regulate bone resorption, in part by influencing osteoclast recruitment and actiṿity,
rather than forming fibrils or transporting hormones.
7.2 How does progressiṿe nephron injury affect angiotensin II actiṿity?
A. Angiotensin II actiṿity is decreased
B. Angiotensin II actiṿity is eleṿated
C. Angiotensin II actiṿity is totally suppressed
D. Angiotensin II actiṿity is not affected
Answer: B. Angiotensin II actiṿity is eleṿated
Expert Rationale: In chronic kidney disease, nephron loss leads to persistent renal
hypoperfusion and chronic actiṿation of the renin–angiotensin–aldosterone system
(RAAS). This results in eleṿated angiotensin II, which further promotes
ṿasoconstriction, sodium retention, and fibrosis, worsening renal damage.
7.3 Which term is used to identify the narrow tubular portion of the long bone that
merges into the neck?
A. Growth plate
B. Diaphysis
C. Metaphysis
D. Epiphysis.
Answer: B. Diaphysis
Expert Rationale: The diaphysis is the long, narrow tubular shaft of a long bone. It
transitions into the metaphysis (“neck”) and then the epiphysis at the ends. The
