Question 1 of 5
An increase or decrease in blood P_CO₂ is always accompanied by a change in plasma H⁺ concentration (plasma pH).
Correct Answer: A
Rationale: True (A): P_CO₂ shifts H⁺ via carbonic acid (CO₂ + H₂O ⇌ H⁺ + HCO₃⁻), affecting pH. False (B) is incorrect.
Question 2 of 5
An increased concentration of O₂ in the plasma contributes to the release of O₂ from hemoglobin to body tissues.
Correct Answer: B
Rationale: False (B): High plasma O₂ increases hemoglobin binding (left shift), not release. Low P_O₂ aids release. True (A) is incorrect.
Question 3 of 5

Correct Answer: D
Rationale: In ectopic pregnancies, the embryo implants outside the uterus, most commonly in the Fallopian tube (D), not the uterus (A), pelvic bone (B), or vagina (C).
