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 ["A","B","D","E","G"]

Explanation

A. Abdomen rigid with decreased bowel sounds: A rigid, tender abdomen suggests peritonitis, a life-threatening complication of peritoneal dialysis requiring immediate intervention.

B. Glucose 220 mg/Dl: Elevated glucose is concerning but not immediately life-threatening compared to the other findings.

C. No dialysis for 24 hours: Missing dialysis leads to toxin accumulation, hyperkalemia, and fluid overload, all of which can be life-threatening.

D. Crackles throughout the lungs: Fluid overload can cause pulmonary edema, leading to respiratory distress. Immediate intervention is needed to prevent respiratory failure.

E. WBC 17,000 mm³: Leukocytosis suggests infection, possibly peritonitis, which requires urgent antibiotic therapy.

F. Hemoglobin 10 g/dL: Mild anemia is expected in CKD and not an emergency.

G. Potassium 7 mEq/L: Severe hyperkalemia is a medical emergency due to the risk of life-threatening cardiac arrhythmias.

H. Creatinine 3 mg/dl: Creatinine is chronically elevated in CKD and not an acute concern.

A. Administer supplemental oxygen B. Secure precautions C. Cardiac monitoring D. Initiating a fluid restriction

Correct Answer is C

Explanation

A. Administer supplemental oxygen: Hypokalemia primarily affects cardiac and neuromuscular function, not oxygenation. Oxygen may be needed if dysrhythmias develop but is not the highest priority.

B. Seizure precautions: While severe hypokalemia can cause muscle weakness, seizures are not the primary concern. Cardiac effects take priority.

C. Cardiac monitoring: A potassium level of 2.2 mEq/L is critically low, increasing the risk of life-threatening cardiac arrhythmias. Continuous cardiac monitoring helps detect dangerous dysrhythmias like ventricular tachycardia.

D. Initiating a fluid restriction: Fluid restriction is more relevant for hyperkalemia or fluid overload, not hypokalemia.
