A nurse is teaching a class about administering IV fluids to treat dehydration. The nurse should include in the teaching that which of the following laboratory values indicates effective treatment of dehydration?

Urine specific gravity 1.020

BUN 28 mg/dl

Serum hematocrit 55%

Serum osmolarity 310 mOsm

Answer and Explanation

The Correct Answer is D

A. Urine specific gravity 1.020: While this value indicates concentrated urine and can be useful in assessing dehydration, it doesn’t specifically confirm effective treatment. High urine specific gravity suggests dehydration because the kidneys are conserving water, but it doesn’t directly confirm the effectiveness of treatment.
B. BUN 28 mg/dl (Blood Urea Nitrogen): Elevated BUN levels can be seen in dehydration, but it's not a direct marker of effective treatment. It indicates dehydration due to increased urea concentration in the blood but doesn’t confirm if the treatment has been effective or not.
C. Serum hematocrit 55%: In dehydration, the blood becomes more concentrated due to water loss, causing an increase in hematocrit levels. However, while this value might indicate dehydration initially, it may not specifically confirm the effectiveness of treatment once initiated.
D. Serum osmolarity 310 mOsm: Serum osmolarity measures the concentration of particles in the blood. In dehydration, the blood becomes more concentrated, leading to increased serum osmolarity. When treatment is effective, rehydration occurs, diluting the blood and bringing serum osmolarity back toward normal levels. Therefore, a decrease in serum osmolarity towards the normal range (280-300 mOsm) would indicate effective treatment of dehydration

Correct Answer is A

Explanation

A. Urticaria (hives): Urticaria is a manifestation of an allergic reaction, which can occur during a transfusion reaction. If the client develops urticaria, it suggests an allergic response, and epinephrine may be administered to manage severe allergic reactions.
B. Distended jugular vein: Distended jugular veins may be associated with fluid overload or cardiovascular issues, but it is not a typical indication for administering epinephrine during a blood transfusion reaction.
C. Bounding pulse: A bounding pulse may be associated with increased cardiac output but is not typically an indication for epinephrine administration during a blood transfusion reaction.
D. Confusion: Confusion is a neurological symptom and is not a typical indication for administering epinephrine during a blood transfusion reaction. Neurological symptoms may suggest other complications that need appropriate interventions.

A. PT 11 seconds B. APTT 50 seconds C. Hematocrit 456 D. Platelets 300,000/mm²

Correct Answer is C

Explanation

A.PT (Prothrombin Time) 11 seconds: The prothrombin time measures the extrinsic pathway of the coagulation cascade. A PT of 11 seconds is within the normal range, and it indicates that the extrinsic clotting pathway is functioning appropriately. There is no need to report this value.
B. APTT (Activated Partial Thromboplastin Time) 50 seconds: The APTT measures the intrinsic pathway of the coagulation cascade. A value of 50 seconds is prolonged and may suggest that the client is receiving an effective anticoagulant dose. However, the APTT target range can vary based on the specific therapeutic goal and the heparin protocol in use. It's essential to follow the healthcare provider's guidance on the target APTT range.
C. Hematocrit 456: The normal range for hematocrit is usually expressed as a percentage. A value of 456 is outside the normal range and likely represents an error or a misinterpretation. The nurse should verify this value, as an extremely high hematocrit could be indicative of an issue such as dehydration or an analytical error.
D. Platelets 300,000/mm²: A platelet count of 300,000/mm² is within the normal range. There is no need to report this value as it suggests a normal platelet count.
