What happens when a hypertonic IV solution is administered to a client?

Fluid will be pushed in the interstitial spaces

Fluid will be pulled out of the cells and into the blood stream.

Fluid will be pushed out of the blood stream into the extravascular spaces.

Fluid will be pulled out of the bloodstream into the cells

Answer and Explanation

The Correct Answer is B

A. Fluid will be pushed into the interstitial spaces. Hypertonic solutions draw water into the bloodstream, not into tissues.

B. Fluid will be pulled out of the cells and into the bloodstream: Hypertonic solutions (e.g., 3% NaCl, D10W) have a higher osmolarity than blood plasma. This pulls fluid from cells into the intravascular space, causing cell shrinkage and increasing blood volume.

C. Fluid will be pushed out of the bloodstream into extravascular spaces. This describes a hypotonic solution’s effect.

D. Fluid will be pulled out of the bloodstream into the cells. This describes an isotonic or hypotonic effect.

Correct Answer is C

Explanation

A. Request a neurological consult: This is likely a metabolic issue (hypocalcemia), not a neurological disorder.

B. Have another nurse take their blood pressure: Rechecking BP does not address the underlying cause of the abnormal movement.

C. Review the client's lab values: Carpopedal spasm (Trousseau's sign) during BP measurement suggests hypocalcemia. The nurse should check serum calcium levels to confirm.

D. Call the healthcare provider for orders: The nurse should first review lab results to provide accurate data when notifying the provider.

A. Respiratory Alkalosis B. Metabolic Acidosis C. Metabolic alkalosis D. Respiratory acidosis

Correct Answer is D

Explanation

A. Respiratory Alkalosis: Would have high pH (>7.45) and low PaCO2 (<35 mmHg).

B. Metabolic Acidosis: Would have low pH and low HCO3 (<22 mEq/L).

C. Metabolic Alkalosis: Would have high pH and high HCO3 (>26 mEq/L).

D. Respiratory Acidosis: A low pH (<7.35) and high PaCO2 (>45 mmHg) indicate respiratory acidosis, which occurs due to hypoventilation, COPD, or respiratory failure. The bicarbonate (HCO3) is normal, meaning there is no metabolic compensation yet.
