Albumin

Answer and Explanation

The Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"B"},"D":{"answers":"C"}}

Solutions	Hypotonic	Isotonic	Hypertonic
0.45% sodium chloride	✅
0.9% sodium chloride		✅
Lactated Ringers		✅
Albumin			✅

0.45% Sodium Chloride (Hypotonic): Has lower osmolarity than blood, causing fluid to shift into cells, making them swell. Used for dehydration and intracellular rehydration.

0.9% Sodium Chloride (Isotonic): Has the same osmolarity as blood, so it stays in the intravascular space. Used for fluid resuscitation (hypovolemia, dehydration, shock).

Lactated Ringers (Isotonic): Contains electrolytes (Na+, K+, Ca2+, lactate), making it ideal for burns, surgery, and trauma patients. Maintains intravascular volume without fluid shifts.

Albumin (Hypertonic): Large protein that pulls fluid into the intravascular space (colloid osmotic pressure). Used for hypovolemia, burns, or severe hypoalbuminemia.

Correct Answer is B

Explanation

A. pH 7.30, PaCO₂ 38, HCO₃ 15: Metabolic acidosis (low HCO₃, normal PaCO₂).

B. pH 7.32, PaCO₂ 56, PO₂ 84, HCO₃ 26: The client has respirations of 8/min, which indicates hypoventilation → CO₂ retention → respiratory acidosis. pH 7.32 indicates acidosis. PaCO₂ 56 mmHg - Elevated CO₂ (hypercapnia), confirming respiratory acidosis. HCO₃ 26- Normal bicarbonate suggests that compensation has not yet occurred

C. pH 7.37, PaCO₂ 45, HCO₃ 24: Normal ABG values.

D. pH 7.48, PaCO₂ 32, HCO₃ 22: Respiratory alkalosis (low PaCO₂ due to hyperventilation, not hypoventilation).

A. Assess the fistula with a large bore needle B. Auscultate the fistula site for a bruit. C. Measure the blood pressure in the affected arm D. Assess the rate and quality of the radial pulse on the affected arm

Correct Answer is B

Explanation

A. Assess the fistula with a large bore needle: Large bore needles are used during dialysis sessions, not for routine assessment. Inappropriate needling can damage the fistula.

B. Auscultate the fistula site for a bruit: A functional AV fistula should have a palpable thrill (vibration) and an audible bruit (whooshing sound) when auscultated with a stethoscope. These findings confirm adequate blood flow and patency.

C. Measure the blood pressure in the affected arm: Blood pressure measurements should never be taken on the fistula arm to prevent compression and potential fistula failure.

D. Assess the rate and quality of the radial pulse on the affected arm: The radial pulse does not accurately assess AV fistula patency; the focus should be on the thrill and bruit.
