The nurse is evaluating the fluid balance of a client who was admitted yesterday with dehydration and who has been receiving IV fluids since admission. An increase in which parameter indicates to the nurse that the client is rehydrating?
Urine specific gravity
Serum hematocrit
Pulse rate
Urinary output
The Correct Answer is D
Choice A reason: Urine specific gravity is a measure of the concentration of solutes in the urine. It is inversely related to the hydration status of the client. A high urine specific gravity indicates dehydration, while a low urine specific gravity indicates overhydration.
Choice B reason: Serum hematocrit is a measure of the percentage of red blood cells in the blood. It is also inversely related to the hydration status of the client. A high serum hematocrit indicates dehydration, while a low serum hematocrit indicates overhydration.
Choice C reason: Pulse rate is a measure of the frequency of the heartbeats. It is directly related to the hydration status of the client. A low pulse rate indicates dehydration, while a high pulse rate indicates overhydration.
Choice D reason: Urinary output is a measure of the amount of urine produced by the kidneys. It is directly related to the hydration status of the client. A low urinary output indicates dehydration, while a high urinary output indicates overhydration.

Correct Answer is A
Explanation
Choice A reason: This is the correct instruction as it ensures that the injection is given in a well-perfused area with minimal risk of injury to major blood vessels or organs. The umbilicus should be avoided as it may harbor bacteria or cause discomfort.
Choice B reason: This is an incorrect instruction as it may result in a loss of medication or inaccurate dosing. The air bubble in the prefilled syringe should be left intact as it helps to seal the medication in the subcutaneous tissue and prevent leakage.
Choice C reason: This is an incorrect instruction as it may cause irritation or inflammation of the injection sites. The gluteal area should be avoided as it has a higher risk of hitting a nerve or blood vessel. The abdomen is the preferred site for low-molecular-weight heparin injections.
Choice D reason: This is an incorrect instruction as it may increase the risk of bleeding or bruising. The injection site should not be massaged or rubbed as it may dislodge the clot or damage the tissue.
Correct Answer is A
Explanation
The correct answer is A. Start collecting the specimen with the next void.
Choice A reason: The 4-hour urine collection for creatinine clearance should start with an empty bladder. The first urine of the day is discarded and the time is noted. All subsequent urine for the next 4 hours, including the first urine the following day, should be collected. If the first sample was put in the urinal hours ago and was not collected, the nurse should start collecting the specimen with the next void.
Choice B reason: Beginning the collection the next day would delay the test and may not be necessary. The test should ideally start after the first urine of the day is discarded.
Choice C reason: Observing the sample for sediment is not typically part of the procedure for a 4-hour urine collection for creatinine clearance. The focus is on collecting all urine for a specified period, not on the physical characteristics of the sample.
Choice D reason: Emptying the sample into the 4-hour container would be incorrect if the sample was the first urine of the day, which should be discarded. The collection should start with the next void.
