Podcast Transcription

Alright, this next condition is hypernatremia. So, first, I wanna define it before I go into your mnemonics. But definition of hypernatremia is the serum sodium level above the limit of 145 mmol/L. So, if you remember the normal level for serum sodium is 135 to 145 mmol/L. Hypernatremia is above that 145. So, it can be caused by too much sodium in the blood but it’s also caused by too little free water in the body. So, you really have to assess the patient’s volume status before knowing how to appropriately treat or you can really do some damage if you’re treating it the wrong way.

 

So, I have 3 mnemonics for your signs and symptoms. And they’re all kinda related. So, they are easy to remember. The first one is FRIED. FRIED. You’re FRIED from learning about sodium. F – Flashed skin, R – Restlessness, I – Increased fluid retention and increased BP, E – Edema, D – Decreased urinary output and dry mouth. You’re fried from learning about sodium. F – flashed skin, R – Restlessness, I – Increased fluid retention, E – Edema, and D – Decreased urine output.

 

My next one is SWINE. SWINE. And I remember this as ‘Bacon has high amounts of sodium.’ And you can fry bacon and swine and there you go. So, SWINE. SWINE. S – Sleepy, W – Weakness, I – Irritability, N – Neuromuscular Excitability, E – Edema. SWINE. S – Sleepy, W – Weakness, I – Irritability, N – Neuromuscular Excitability, E – Edema.

 

Our last one is SALT. SALT. Skin flashed, Agitation, Low grade fever, and Thirst. S – skin flashed, A – Agitation, L – Low grade fever, and T – Thirst. So, those are some signs and symptoms of hypernatremia.

 

So, here’s one for causes of hypernatremia. MODEL. MODEL. M – Medications or Meals, O – Osmotic Diuretics. D – Diabetes insipidus, E – Excessive water loss, and L – Low water intake. MODEL. M – Medications or Meals, O – Osmotic Diuretics, D – Diabetes Insipidus, E – Excessive water loss, and L – Low water intake. And those are some mnemonics to help you remember signs and symptoms and causes of hypernatremia.
