Which statement is true about the sodium-potassium pump?

It is a passive process.

It increases the loss of water from the body.

It causes hyperkalemia, as it pulls potassium out of the intracellular fluid.

It maintains the equilibrium between the intracellular and extracellular fluid.

Which statement reflects the relationship of magnesium to other electrolytes?

Serum levels of magnesium are related to serum levels of sodium and chloride.

Serum levels of magnesium are related to serum levels of calcium and chloride.

Serum levels of magnesium are related to serum levels of potassium and calcium.

Serum levels of magnesium are related to serum levels of potassium and sodium.
Sodium is the primary extracellular cation and is frequently lost with vomiting. This can lead to hyponatremia.

Chloride is an extracellular anion, electrically attracted to sodium, and lost with vomiting.

Potassium is an intracellular cation that is frequently lost with vomiting.
An individual arrives for an annual physical, and the lab work shows the chloride level is high. Which additional electrolyte would you expect to be high?Sodium Sodium and chloride have an affinity for one another due to their opposite electrical charges. If the chloride level is high, the sodium level will be high.Which statements reflect the role of magnesium?Necessary for the synthesis of proteins and DNA Magnesium is necessary for the synthesis of proteins and DNA, as well as a variety of other enzymatic reactions. Correct Needed for muscle contraction and nerve transmission Magnesium is the second most common cation in the intracellular fluid (ICF) and is needed for muscle contraction and nerve transmission. Correct Important to a variety of enzymatic reactions within the body Magnesium is an intracellular ion (positively charged) that is important to enzymatic reactions in the body.Which electrolyte is required for the storage of glycogen in the liver?Potassium Potassium is the primary intracellular ion and is necessary for the storage of glycogen and glucose in the liver. IncorrectAn individual presents in diabetic ketoacidosis. Knowing that acidosis influences electrolyte functioning, which laboratory value would be expected?High potassium In acidosis, hydrogen ions diffuse from the blood into the cell. As they enter the ICF, potassium is displaced into the ECF to maintain electrical neutrality, resulting in higher potassium levels.Which statement describes a cause of hyperkalemia?Abnormal ECG Hyperkalemia often presents with cardiac dysrhythmias, which can be fatal if the potassium levels are not corrected. History of renal failure Patients with a history of renal failure are at risk for hyperkalemia, as the body retains potassium with renal disease. Clinical complaint of weakness Hyperkalemia causes decreased neuromuscular activity leading to muscle weakness.An individual presents in the clinic with repetitive movements in the hands. Which statement is the probable cause of the repetitive movements?Chorea Chorea is defined as involuntary, repetitive movements and is often seen in hypomagnesemia.Which statements found in a person's medical record would lead the practitioner to consider the likelihood of hypokalemia?Laxative abuse With diarrhea, fluid and electrolyte losses can be excessive, with several liters of fluid (100 to 200 mEq of potassium) lost per day. The loss of fluid and sodium stimulates the secretion of aldosterone, which in turn causes renal losses of potassium thus causing hypokalemia. Correct Loop diuretic therapy Diuretic therapy causes the excretion of potassium, particularly if potassium-sparing diuretics are not used.
