A nurse is caring for an adult client who has a fever of 39.4°C (103°F) and is receiving 0.9% sodium chloride IV at 125 mL/hr. Over the last hour, the nurse notes that the client's urine output is 20 mL. The nurse should report this finding to the provider and anticipate a prescription for what?
An antipyretic medication
A diuretic medication
A blood culture
A fluid bolus
The Correct Answer is D
Choice A reason: An antipyretic medication is not the best answer because it does not address the client's low urine output. An antipyretic medication is a drug that lowers the body temperature by reducing the production of heat or increasing the loss of heat. It may help the client feel more comfortable, but it does not improve the kidney function or prevent dehydration.
Choice B reason: A diuretic medication is not the best answer because it may worsen the client's low urine output. A diuretic medication is a drug that increases the excretion of water and electrolytes by the kidneys. It may lower the blood pressure and reduce the fluid overload, but it may also cause dehydration, electrolyte imbalance, and kidney damage.
Choice C reason: A blood culture is not the best answer because it does not address the client's low urine output. A blood culture is a laboratory test that detects the presence of bacteria or other microorganisms in the blood. It may help identify the cause of the fever and guide the antibiotic therapy, but it does not improve the kidney function or prevent dehydration.
Choice D reason: A fluid bolus is the best answer because it may improve the client's low urine output. A fluid bolus is a rapid infusion of a large volume of fluid, usually isotonic saline or lactated Ringer's solution. It may increase the blood volume and pressure, improve the tissue perfusion, and stimulate the urine production. It may also help lower the fever by diluting the pyrogens and increasing the heat loss.

Correct Answer is D
Explanation
Choice A reason: This is not a correct answer because 0.9% Sodium Chloride is an isotonic solution, which means it has the same osmolarity as the blood plasma. It does not cause any fluid shifts between the intracellular and extracellular compartments.
Choice B reason: This is not a correct answer because Lactated Ringer's is an isotonic solution, which means it has the same osmolarity as the blood plasma. It does not cause any fluid shifts between the intracellular and extracellular compartments.
Choice C reason: This is not a correct answer because D5W (5% Dextrose in Water) is an isotonic solution when it is in the IV bag, but it becomes hypotonic once it enters the body, as the dextrose is rapidly metabolized and only water remains. However, it is not a preferred solution for a patient with critically high sodium, as it can cause cerebral edema and worsen the neurological status.
Choice D reason: This is a correct answer because 0.45% Sodium Chloride is a hypotonic solution, which means it has a lower osmolarity than the blood plasma. It causes fluid to shift from the extracellular to the intracellular compartment, which can help lower the sodium level and correct the fluid imbalance.
Correct Answer is D
Explanation
Choice A reason: Half-normal saline solution is a hypotonic solution, which means it has a lower concentration of solutes than the blood plasma. It can cause fluid to shift from the blood vessels into the cells, leading to cellular swelling and edema.
Choice B reason: 10% dextrose in water is a hypertonic solution, which means it has a higher concentration of solutes than the blood plasma. It can cause fluid to shift from the cells into the blood vessels, leading to cellular shrinkage and dehydration.
Choice C reason: 5% dextrose and half-normal saline solution is a hypertonic solution, which has the same effects as choice B. The dextrose increases the osmolarity of the solution, while the half-normal saline provides some electrolytes.
Choice D reason: Lactated Ringer's solution is an isotonic solution, which means it has the same concentration of solutes as the blood plasma. It maintains fluid balance and provides electrolytes such as sodium, potassium, calcium, and lactate. It is commonly used for fluid resuscitation, dehydration, and acidosis.
