A client with fluid retention is ordered hydrochlorothiazide (Microzide). The nurse provides education about possible electrolyte imbalances related to thiazide diuretic therapy. To help prevent thiazide-related complications, the client should be encouraged to consume foods and fluids that contain which electrolyte?

Calcium

Selenium

Potassium

Bicarbonate

Answer and Explanation

The Correct Answer is C

A. Calcium: Thiazide diuretics can increase calcium levels, but the primary concern is the potential loss of potassium.
B. Selenium: This is not directly related to thiazide diuretic therapy and does not address the primary electrolyte imbalance.
C. Potassium: This is the correct choice. Thiazide diuretics can cause hypokalemia (low potassium levels). Encouraging potassium-rich foods helps to counteract this side effect.
D. Bicarbonate: While bicarbonate can be important for acid-base balance, it is not the primary concern with thiazide diuretics, which typically affect potassium levels.

Correct Answer is C

Explanation

A. Respiratory acidosis without compensation: The pH of 7.22 indicates acidosis, but the HCO3 level of 23 mEq/L suggests that compensation is occurring because the HCO3 is within the normal range for respiratory acidosis.
B. Metabolic acidosis with full compensation: The high PaCO2 level is more indicative of respiratory issues, not metabolic acidosis. Additionally, compensation for metabolic acidosis would show elevated HCO3.
C. Respiratory acidosis with partial compensation: The elevated PaCO2 and low pH indicate respiratory acidosis. The normal HCO3 level suggests partial compensation by the kidneys.
D. Metabolic acidosis without compensation: The elevated PaCO2 and normal HCO3 suggest respiratory acidosis rather than metabolic acidosis.

A. Chest x-ray results B. Serum osmolality C. Intake and output record D. Serum glucose level

Correct Answer is A

Explanation

A. Chest x-ray results: This is the correct choice. After central venous catheter insertion, a chest x-ray is crucial to confirm correct catheter placement and to rule out complications such as pneumothorax or catheter malposition.
B. Serum osmolality: While serum osmolality can provide information about fluid and electrolyte balance, it is not directly related to verifying catheter placement or the immediate post-insertion assessment.
C. Intake and output record: Although important for monitoring fluid balance, the intake and output record does not confirm the proper placement of the central venous catheter.
D. Serum glucose level: This is not relevant to verifying the catheter placement or ensuring proper functioning immediately after insertion.
