CHP 5 & 6 NR 283 FOR EXAM 2 2026 STYLE
QUESTIONS WITH DETAILED, ACCURATE
ANSWERS.
Magnesium - CorreCt Answers -It serves many important functions, including taking
part in the production of energy (adenosine triphosphate), DNA and protein synthesis,
carbohydrate metabolism, nerve transmission, parathyroid hormone production (which
regulates calcium), and is important in heart function.
When magnesium levels get too high (hypermagnesemia) - CorreCt Answers -it can
depress the central nervous system (CNS). This can cause lethargy, muscle weakness,
loss of reflexes, low blood pressure, and heart rhythm problems.
When magnesium levels get too low (hypomagnesemia) - CorreCt Answers -it can
lead to respiratory muscle paralysis, coma, and heart arrest. Symptoms aggravate the
central nervous system (CNS) and can include confusion, reduced consciousness,
muscle lock-up (tetany), muscle cramps, and strong reflexes (nerve excitability).
Magnesium (Mg2+) - CorreCt Answers -is an intracellular ion with about 50% stored
in bone. Changes in serum magnesium levels are linked to both potassium and calcium
levels. Magnesium is a component of many enzyme reactions and in protein and DNA
synthesis.
Magnesium - Pathophysiology - CorreCt Answers -Decreased magnesium levels
interfere with the enzyme reactions required for many bodily functions, including
protein and DNA synthesis.
Low magnesium increases cardiac muscle irritability.
Because potassium, calcium, and magnesium work together to maintain a neutral
intracellular electrical charge, it is difficult to maintain a normal potassium level when
the serum magnesium level is low.
,A person with a low magnesium level is most likely to experience which symptoms? -
CorreCt Answers -seizures
tetany
tremors
chloride - CorreCt Answers -The brain uses sodium chloride, the salt made when
sodium and chloride bind, to attract water and make cerebrospinal fluid (CSF). In the
stomach, hydrogen binds to chloride to make hydrochloric acid, a chemical critical to
digestion.
Hypochloremia - CorreCt Answers -Hypochloremia rarely occurs alone; most often,
changes happen with parallel shifts in sodium or bicarbonate levels.
Hyperchloremia - CorreCt Answers -Serum chloride levels greater than 106 mEq/L
Chemical Combinations - CorreCt Answers -Symbol
Chemical Compound
Function
K+

Which action by the student could have prevented them from becoming hyponatremic? -
CorreCt Answers -Drank an isotonic sports drink instead of water
Which items should be included in the diet of a person who wants to increase their
calcium intake? - CorreCt Answers -Calcium is found naturally in dairy products,
such as milk and cheese, green, leafy vegetables, and almonds.lkm’fcji lazdxcv

Which clients are at risk for hypomagnesemia due to preexisting alterations in health? -
CorreCt Answers -Conditions that place a person at high risk for hypomagnesemia
include diuretic use, diabetic ketoacidosis (high blood sugar leading to ketone
formation), hypoparathyroidism, malnourishment, and alcohol use disorder.
Location of Potassium - CorreCt Answers -In a healthy person, most of the
potassium in the body is located inside the cells
What alteration is present in a person with hyperkalemia? Correct Answers -they have
too much potassium.
Which clinical manifestation is not associated with hyperkalemia? - CorreCt Answers
-A positive Chvostek's sign is associated with hypocalcemia and seen as a twitching of
the facial muscles in response to gently tapping on a person's cheek, in front of their ear.
, Decreased blood pressure, muscle twitches and cramps, and a weak and slow heart rate
are associated with hyperkalemia.
Potassium supports many bodily functions, including - CorreCt Answers -acid-base
balance
intracellular fluid volume
metabolic processes
nerve conduction
muscle contraction
cell membrane potential
Most importantly, abnormal potassium levels, both high and low, have a significant and
serious effect on the heart muscle and conduction of electrical impulses that stimulate
cardiac contraction and regulate heart rate.
Hypokalemia - CorreCt Answers -Prolongs repolarization of cardiac muscles due to
loss of intracellular potassium
This may lead to cardiac arrest.
What occurs during osmosis? - CorreCt Answers -Water moves from an area of lower
solute concentration to an area of higher solute concentration.
Hydrostatic pressure - CorreCt Answers -Hydrostatic pressure is the pressure
exerted to push fluid from one compartment to another.
For example, when pressure in the blood vessels, or blood pressure, is higher, more fluid
may be pushed from the intravascular area to the extracellular spaces where the
pressure is lower.
Osmotic pressure - CorreCt Answers -Osmotic pressure draws fluid from an area of
higher concentration to one of lower concentration.
