The physician has prescribed 30 mEq of potassium gluconate to be given orally once a day in orange juice.
The available concentration of potassium gluconate is 20 mEq per 15 mL.
What is the amount of mL the nurse will administer Instructions: Rounding: For adult clients, the answer should be rounded to the nearest whole number (mg, mcg, and m).
The Correct Answer is ["23"]
The correct answer is 22.5 mL.
To find the amount of mL, use the formula: (desired dose / available dose) x available volume.
In this case, desired dose = 30 mEq, available dose = 20 mEq, and available volume = 15 mL.
Plug these values into the formula: (30 mEq / 20 mEq) x 15 mL = 22.5 mL.
However, since the instructions say to round to the nearest whole number for adult clients, the final answer is 23 mL.

Correct Answer is A
Explanation
Sodium is the major extracellular electrolyte in the body.
It is responsible for maintaining the extracellular fluid volume, and also for regulation of the membrane potential of cells.
Sodium is exchanged along with potassium across cell membranes as part of active transport.
Choice B is wrong because potassium is mainly an intracellular ion.
It is important for nerve and muscle function, but it is not the predominant electrolyte in the extracellular fluid.
Choice C is wrong because calcium is not the major electrolyte in the extracellular fluid.
Calcium is mostly found in bones and teeth, where it forms a mineral reserve with phosphate.
Calcium also plays a role in muscle contraction, blood clotting, and enzyme activity.
Choice D is wrong because magnesium is not the major electrolyte in the extracellular fluid.
Magnesium is mostly found in bones, where it helps to stabilize the structure of ATP2.
Magnesium also participates in enzyme reactions, nerve and muscle function, and protein synthesis.
Correct Answer is C
Explanation
Angiotensin II is a hormone that stimulates the adrenal cortex to release aldosterone. Aldosterone is a hormone that helps regulate blood pressure by increasing the reabsorption of sodium and water and the excretion of potassium by the kidneys.
Choice A is wrong because renin is not a hormone but an enzyme that catalyzes the conversion of angiotensinogen to angiotensin I1.
Choice B is wrong because angiotensin I is an inactive precursor of angiotensin II that is converted by angiotensin-converting enzyme (ACE) in the lungs.
Choice D is wrong because antidiuretic hormone (ADH) is a hormone that regulates water balance by increasing the reabsorption of water by the kidneys, but it does not affect aldosterone secretion.
