A client is diagnosed with hypercalcemia.
Which of the following clinical manifestations would the nurse expect to observe (Select all that apply).
Muscle spasms.
Confusion.
Constipation.
Bradycardia.
Polyuria.
Correct Answer : B,C,D
Hypercalcemia is a condition in which the calcium level in the blood is above normal.
This can cause various symptoms, such as confusion, constipation, and bradycardia (slow heart rate).
These are the clinical manifestations that the nurse would expect to observe in a client with hypercalcemia.
Choice A is wrong because muscle spasms are not a common symptom of hypercalcemia.
In fact, hypercalcemia can cause muscle weakness and pain.
Choice E is wrong because polyuria (excessive urination) is not a direct symptom of hypercalcemia, but rather a result of kidney problems caused by hypercalcemia.
Hypercalcemia can make the kidneys work harder to filter the excess calcium, leading to dehydration and thirst.
However, this does not necessarily mean that the client will have polyuria.
Normal ranges for calcium levels in the blood are 8.5 to 10.2 mg/dL (milligrams per deciliter) or 2.1 to 2.6 mmol/L (millimoles per liter).

Correct Answer is A
Explanation
SIADH is a condition in which your body makes too much antidiuretic hormone (ADH), which controls how your body releases and conserves water.
SIADH makes it harder for your kidneys to release water and causes the levels of electrolytes, like sodium, to fall due to water retention.
This leads to hyponatremia, which is when you have low levels of sodium in your blood.
Choice B is wrong because hypernatremia is when you have high levels of sodium in your blood.
This can occur due to dehydration, excessive salt intake, or kidney problems.
Choice C is wrong because hyperkalemia is when you have high levels of potassium in your blood.
This can occur due to kidney failure, acidosis, or certain medications.
Choice D is wrong because hypokalemia is when you have low levels of potassium in your blood.
This can occur due to vomiting, diarrhea, diuretics, or alkalosis.
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.
