A nurse is reviewing a client’s laboratory results. Which of the following findings should the nurse report to the provider?
Magnesium 1.9 mg.
Chloride 99 mEq/L.
Sodium 126 mEq/L.
Potassium 3.6 mEq/L.
The Correct Answer is C
a. Magnesium 1.9 mg: This magnesium level is within the expected reference range (1.3-2.1 mEq/L).
b. Chloride 99 mEq/L: This chloride level is within the expected reference range (98-106 mEq/L).
c. Sodium 126 mEq/L: A sodium level of 126 mEq/L is significantly below the normal range (135-145 mEq/L), indicating hyponatremia, which can have serious consequences and requires prompt attention.
d. Potassium 3.6 mEq/L: This potassium level is within the expected reference range (3.5-5.0 mEq/L).

Correct Answer is B
Explanation
a. Neck vein distention: Neck vein distention may indicate fluid overload, but it is not a direct measure of fluid losses.
b. Body weight: Monitoring body weight before and after hemodialysis provides a direct
measure of fluid losses. Hemodialysis removes excess fluid, and changes in body weight reflect fluid balance.
c. Abdominal girth: Abdominal girth may be affected by fluid accumulation but is not a direct measure of fluid losses during hemodialysis.
d. Blood pressure: While blood pressure may be influenced by fluid status, it is not a specific measure of fluid losses during hemodialysis. Body weight is a more direct indicator of fluid removal.
Correct Answer is A
Explanation
a. Prothrombin time (PT): Warfarin affects the extrinsic pathway of the coagulation cascade, and PT is the primary diagnostic test used to monitor the therapeutic effect of warfarin. It measures
the time it takes for blood to clot.
b. Platelet count: Platelet count assesses the number of platelets in the blood and is not specifically used to monitor the effect of warfarin.
c. White blood cell count (WBC): WBC count assesses the number of white blood cells and is not specifically used to monitor the effect of warfarin.
d. Activated partial thromboplastin time (aPTT): While aPTT is a valuable test for monitoring the therapeutic effect of heparin, it is not the primary test for warfarin. Warfarin primarily affects the extrinsic pathway, and PT is more appropriate for monitoring its effects.
