A client is admitted to the hospital with cerebral edema.
The nurse is preparing to start an intravenous (IV) infusion.
Which of the following IV fluids is the most appropriate for this client?
Normal saline (0.9% NaCl).
Half normal saline (0.45% NaCl).
Lactated Ringer’s.
D5W (5% dextrose in water).
The Correct Answer is A
Normal saline (0.9% NaCl).
Choice A rationale:
Normal saline (0.9% NaCl) is the most appropriate choice for a client with cerebral edema.
This isotonic solution is commonly used to maintain intravascular volume and provides a neutral effect on fluid balance in the brain.
It does not introduce additional electrolytes that could potentially worsen cerebral edema.
Choice B rationale:
Half normal saline (0.45% NaCl) is not the best choice for cerebral edema because it is hypotonic and may lead to cellular swelling, potentially exacerbating the edema.
Choice C rationale:
Lactated Ringer's, while isotonic, contains additional electrolytes and lactate.
In the case of cerebral edema, it is safer to use a solution with a simpler composition like normal saline to avoid any potential complications related to electrolyte imbalances.
Choice D rationale:
D5W (5% dextrose in water) is not recommended for cerebral edema because it contains dextrose and may not adequately address the underlying issue of increased intracranial pressure associated with cerebral edema.

Correct Answer is ["A","B","C","D"]
Explanation
Choice A rationale:
Thirst and dry mouth are early signs of dehydration.
When the body loses fluids, it signals the brain to increase thirst and conserve water.
Dry mouth can occur due to reduced saliva production when the body is dehydrated.
Choice B rationale:
Decreased urine output and dark-colored urine are indicators of concentrated urine, suggesting dehydration.
Reduced fluid intake or excessive fluid loss can lead to decreased urine production, and the urine becomes more concentrated, appearing darker than usual.
Choice C rationale:
Rapid heart rate and low blood pressure are signs of hypovolemic shock, a severe form of dehydration where the body cannot circulate enough blood to meet its needs.
This can happen in severe cases of dehydration when there is a significant loss of fluids and electrolytes.
Choice D rationale:
Poor skin turgor is a classic clinical sign of dehydration.
Skin turgor refers to the skin's ability to return to its normal position after being pinched.
In dehydrated individuals, the skin loses elasticity and remains tented or "pinched" after being pulled up.
This indicates a lack of fluid in the body.
Choice E rationale:
Increased energy and playfulness are not typical signs of dehydration.
Dehydrated children are more likely to be lethargic and irritable due to the physiological stress on their bodies.
Correct Answer is A
Explanation
Choice A rationale:
“This fluid will help to restore my sodium levels and replace the fluids I lost from vomiting.”.
The client should understand that they are receiving Half Normal Saline (0.45% NaCl) to restore sodium levels and replace lost fluids due to vomiting.
Half Normal Saline contains 77 mEq/L of sodium and 77 mEq/L of chloride, making it a suitable choice for a patient with mild hyponatremia and fluid loss from vomiting.
It helps restore sodium levels without the risk of overcorrection seen with 0.9% NaCl.
Choice B rationale:
“This fluid will help to lower my sodium levels and replace the fluids I lost from sweating.”.
Half Normal Saline is not used to lower sodium levels; its purpose is to restore sodium levels and provide fluids for cases like vomiting or other fluid losses.
Sweating typically leads to fluid loss, not sodium loss, and Half Normal Saline is not a treatment for high sodium levels.
Choice C rationale:
“This fluid will help to restore my potassium levels and replace the fluids I lost from vomiting.”.
Half Normal Saline does not address potassium levels, and the primary reason for using it is to address sodium imbalances and fluid loss, not potassium-related issues.
Choice D rationale:
“This fluid will help to lower my potassium levels and replace the fluids I lost from sweating.”.
Half Normal Saline is not used to lower potassium levels and is not specifically indicated for treating high potassium.
Additionally, it is not typically used to address fluid loss from sweating.
