1
Q

Meaning of Hypomagnesemia

A

Low levels of magnesium in the blood

2
Q

Normal levels of Magnesium

A

1.6-2.6

3
Q

Level of hypomagnesemia

A

< 1.6

4
Q

Magnesium plays a role in

A

major cell functions like transferring and storing energy, regulation of parathyroid hormone PTH (which also plays a role in calcium levels). In hypomagnesemia, the release of calcium is inhibited and that is why you will see hypocalcemia if you have low magnesium level. Magnesium also plays a role in the metabolism of carbs, lipids, and proteins, and blood pressure regulation.

5
Q

Where is magnesium absorbed?

A

Magnesium is absorbed in the small intestine and excreted via the kidneys (any issues with these systems can cause magnesium level issues).

6
Q

Saying for Causes of Hypomagnesemia

A

“Low Mag”

7
Q

“(L)ow Mag”

A

Limited intake Mg (Starvation)

8
Q

“L(o)w Mag”

A

Other electrolyte issues cause low mag levels

9
Q

“Lo(w) Mag”

A

Wasting magnesium kdineys (loop and thiazide diuretics and cyclosporine … stimulates the kidneys to waste Mag)

10
Q

“Low (M)ag”

A

Malabsorption issues (Crohn’s, Celiac, proton-pump inhibitors drugs “Prilosec, Nexium, Protonix”…drug family ending in “prazole” Omeprazole, diarrhea/vomiting)

11
Q

“Low M(a)g”

A

Alcohol (due to poor dietary intake, alcohol stimulates the kidneys to excreted mag, acute pancreatitis)

12
Q

“Low Ma(g)”

A

Glycemic issues (Diabetic Ketoacidosis, insulin administration)

13
Q

Saying for Signs and Symptoms of Hypomagnesemia

A

Remember “Twitching” because the body is experiencing neuromuscular excitability. This is the OPPOSITE in hypermagnesemia where everything system of the body is lethargic.

14
Q

“(T)witching”

A

Trouesseau (Positive due to hypocalcemia)

15
Q

“T(w)itching”

A

Weak Respirations

16
Q

“Tw(i)tching”

A

Irritability

17
Q

“Twi(t)ching”

A

Torsades de pointes (abnormal heart rhythm that leads to sudden cardiac death) Tetany (seizures)

18
Q

“Twit(c)hing”

A

Cardiac Changes and Chvosteks Signs

19
Q

“Twitc(h)ing”

A

Hypertension, Hyperreflexia

20
Q

“Twitch(i)ng”

A

Involuntary Movements

21
Q

“Twitchi(n)g”

A

Nausea

22
Q

“Twitchin(g)”

A

GI Issues

23
Q

Nursing Intervention - Cardiac

A

Monitor Cardiac , Gi , Respiratory, Neuro Status

24
Q

Nursing Intervention - What to administer

A

May administer potassium supplements due to hypokalemia (hard to get magnesium level up if potassium level is down)

25
Q

Supplements

A

Administer calcium supplements

26
Q

How should Magnesium be administer?

A

Administer Magnesium Sulfate IV Route

27
Q

What other electrolyte levels should be watched out for?

A

Like calcium and potassium
