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
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 D
Explanation
A. Administer more than one pill to the client at a time: Administering more than one pill at a time may increase the risk of choking, especially for individuals with dysphagia. It's generally advisable to administer one medication at a time to ensure proper swallowing.
B. Tilt the client's head back when administering the medications: Tipping the head backward can increase the risk of aspiration (inhalation of medication into the airways). It is recommended to keep the head in a neutral or slightly forward position to facilitate swallowing.
C. Place the medications on the back of the client's tongue: Placing medications on the back of the tongue may trigger the gag reflex and increase the risk of aspiration. Medications should be placed on the front of the tongue to allow for better control and coordination of swallowing.
D. Mix the medications with a semisolid food for the client (Correct Answer): Mixing medications with a semisolid food, often referred to as "food thickening," can be beneficial for clients with dysphagia. This helps make the medications easier to swallow and reduces the risk of choking or aspiration. However, it is important to check with the healthcare provider or pharmacist to ensure compatibility with specific medications.
Correct Answer is D
Explanation
A. "If I were you, I would get the vaccine to keep my family safe:"
This statement imposes the nurse's personal opinion on the client and may not respect the client's autonomy and decision-making.
B. "Influenza can be very serious to anyone who does not receive the vaccine:"
While this statement conveys the seriousness of influenza, it may be perceived as coercive or fear-inducing. It is important to provide information without pressure.
C. "The influenza vaccine is mandatory for all clients before discharge, so you will need to sign an against medical advice form:"
This statement is not accurate and may create unnecessary tension. Influenza vaccination is generally not mandatory, and clients have the right to decline without being labeled against medical advice for this particular vaccination.
D. "The influenza vaccine is strongly encouraged, but I understand you would like to decline right now:"
This is the correct answer. It acknowledges the client's decision to decline the vaccine while expressing that the vaccine is encouraged. It respects the client's autonomy and allows for open communication about the decision.
