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

Answer and Explanation

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 most important intervention because a high serum potassium level can cause cardiac dysrhythmias, which can be life-threatening. The nurse should monitor the client's heart rate and rhythm closely and report any changes or abnormalities to the healthcare provider.

Choice B reason: This is not the most important intervention because the color and amount of urine are not directly related to the serum potassium level. The nurse should assess the client's renal function and fluid balance, but these are not the priority assessments.

Choice C reason: This is also not the most important intervention because the muscle strength is not the most sensitive indicator of the serum potassium level. The nurse should evaluate the client's neuromuscular status and watch for signs of weakness or paralysis, but these are not the priority assessments.

Choice D reason: This is another incorrect intervention because the deep tendon reflexes are not the most reliable indicator of the serum potassium level. The nurse should check the client's reflexes and note any hyperreflexia or hyporeflexia, but these are not the priority assessments.

A. The technique is intended to maintain straight spinal alignment. B. Using two or three people increases client safety. C. Working together can decrease the risk of back injury to the nurses. D. Turning instead of pulling reduces the likelihood of skin damage.

Correct Answer is A

Explanation

Choice A reason: This is the best explanation as it describes the main goal of the log-rolling technique, which is to prevent twisting or bending of the spine. This is especially important for clients who have spinal injuries, surgeries, or disorders.

Choice B reason: Using two or three people is a part of the log-rolling technique, but it is not the purpose of it. It is a means to achieve the purpose of maintaining spinal alignment. It also ensures that the client is moved smoothly and gently.

Choice C reason: Working together can decrease the risk of back injury to the nurses, but it is not the purpose of the log-rolling technique. It is a benefit for the nurses, but not for the client. The nurse should focus on the client's needs and outcomes.

Choice D reason: Turning instead of pulling reduces the likelihood of skin damage, but it is not the purpose of the log-rolling technique. It is an advantage for the client, but not the main reason for using the technique. The nurse should explain how the technique affects the spine, not the skin.
