A client with dry skin and mucous membranes is weak, has orthostatic blood pressure changes, and has decreased urine output. The serum osmolality is 290 mOsm/kg. What IV fluid should the nurse anticipate being prescribed for this client?

0.45% Sodium Chloride

10% dextrose in water

5% dextrose in water

0.9% Sodium Chloride

Answer and Explanation

The Correct Answer is D

A. 0.45% Sodium Chloride: This is a hypotonic solution, which is not appropriate for a client with normal serum osmolality (290 mOsm/kg). It may cause fluid shifts that are not desirable in this context.
B. 10% dextrose in water: This hypertonic solution is generally used for providing calories rather than correcting fluid imbalance and is not suitable for initial rehydration in this scenario.
C. 5% dextrose in water: This solution is isotonic in the bag but becomes hypotonic in the body. It is not the best choice for rehydrating a client with normal serum osmolality and significant fluid loss.
D. 0.9% Sodium Chloride: This isotonic solution is appropriate for rehydration in a client with normal serum osmolality. It helps restore extracellular fluid volume without causing fluid shifts, making it ideal for this situation.

Correct Answer is C

Explanation

A. Client's serum pH is 7.41: This is within the normal range for blood pH (7.35-7.45) and does not specifically indicate a potassium deficit.
B. Client has a stage 2 sacral wound: This is related to skin integrity and does not directly impact potassium levels.
C. Client requires continuous nasogastric suction: Continuous nasogastric suction can lead to the loss of potassium as it removes gastric contents, which may include electrolytes.
D. Client has a history of adrenal insufficiency: While adrenal insufficiency can affect electrolyte balance, continuous nasogastric suction is a more immediate risk for potassium deficit.

A. The client with a serum phosphorus of 4.5 mg/dL that requires assistance with planning their meals B. The client with a serum magnesium of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes C. The client with a serum potassium of 5.3 mEq/L and is scheduled for hemodialysis in three hours D. The client with a serum sodium of 145 mEq/L who is complaining of a dry mouth and wants a glass of water

Correct Answer is B

Explanation

A. The client with a serum phosphorus of 4.5 mg/dL that requires assistance with planning their meals: A serum phosphorus level of 4.5 mg/dL is within the normal range, and assistance with meal planning is a lower priority compared to the other situations.
B. The client with a serum magnesium of 1.1 mEq/L who has tremors and hyperactive deep tendon reflexes: This client has hypomagnesemia, which can lead to severe complications like seizures or cardiac arrhythmias. Immediate attention is necessary due to the symptoms and the critically low magnesium level.
C. The client with a serum potassium of 5.3 mEq/L and is scheduled for hemodialysis in three hours: This potassium level is slightly elevated, but the scheduled hemodialysis suggests the issue will be addressed soon.
D. The client with a serum sodium of 145 mEq/L who is complaining of a dry mouth and wants a glass of water: A serum sodium of 145 mEq/L is on the high end of normal; the client's dry mouth is concerning but not as urgent as the issues presented by the hypomagnesemia.
