Correct Answer is A
Explanation
A. Isotonic: An isotonic solution has the same solute concentration as blood plasma; thus, 0.9% NaCl does not cause cells to shrink or swell.
B. Exotonic: "Exotonic" is not a recognized term in fluid balance or physiology.
C. Hypotonic: A hypotonic solution (like 0.45% NaCl) has a lower solute concentration than blood, causing water to move into cells, possibly leading to swelling.
D. Hypertonic: A hypertonic solution (like 3% NaCl) has a higher solute concentration than blood, causing water to leave cells and leading to cell shrinkage.
Correct Answer is B
Explanation
A. Lymphedema:
Lymphedema is localized fluid accumulation due to lymphatic obstruction, usually unilateral and not associated with dyspnea or heart failure signs.
B. Congestive heart failure (CHF):
CHF leads to fluid buildup (causing JVD, edema) and respiratory symptoms (cough, dyspnea) due to impaired heart pumping.
C. Endocarditis:
Endocarditis is an infection of the heart valves, presenting more with fever, murmurs, and embolic signs, not classic CHF symptoms.
D. Atrial fibrillation:
AFib causes irregular heart rhythm, and may contribute to CHF, but on its own, AFib doesn’t cause pitting edema and JVD without underlying CHF.
