Section 1: Nursing, Hyponatremia, Clinical (Q1–Q15)
Question & Answer
Q1 HYPOnatremia
A due to sodium LOSS or water GAIN <136
Q2 if its fluid or sodium loss
A Hypovolemia, if you ever have low fluids you will always have hypotension (weak, thready pulse)
Q3 Water gain
A Hypervolemia (bounding pulse, normally high BP)
Q4 Clinical manifestation of HYPOnatremia
A NEURO changes (important) -seizures, decreased LOC, coma, weakness put pt on seizure
precautions
Q5 Nursing itnerventions HYPOnatremia
A sodium loss-replace fluids and give hypertonic solutions water gain-restrict water intake, may put
on diuretic
Q6 HYPERnatremia
A sodium gain or water loss >145
Q7 Clinical manifestation of HYPERnatremia
A THINK DRY thirst-first indication (not accurate in cognitvely imapired or older adults) change in LOC,
agitation, lethargic to comatose skeletal muscle twitching decreased cardiac contractility
Q8 HYPERnatremia nursing interventions
A Fluid loss- IV fluid, HYPOtonic solution (0.45% NS, may give D5%) if not caused by fluid loss- D5W
which will help get rid of the sodium by rehydrating diuretics
Q9 HYPOkalemia
A low potassium <3.5 mEq/L
Q10 Clinical Manifestation of HYPOkalemia
A CARDIAC changes—very serious and deadly complications (important) assess EKG, rhythm, rate
and force of CV system. -muscle weakness, shallow respirations -skeletal muscle weakness -
changes in LOC, abd distention, hypoactive BS
Q11 Nursing interventions of HYPOkalemia
A Potassium replacement PO potassium-may cause n/v take w food NEVER PUSH potassium, Rate
should NOT EXCEED 10 mEq/hr

Question & Answer
Q12 HYPERkalemia
A High potassium >5.0
Q13 Clincial manifestations of HYPERkalemia
A -EKG changes (important), dysrhythmias -Hyperactive BS-body is trying to expell potassium
Q14 Nursing interventions HYPERkalemia
A -Sodium polystyrene sulfonate (aka Kayexalate)- removes postassium through stool and is drank
through a straw -Diuretics: non-potassium sparing (we want FUROSEMIDE not spironolactone) -
Emergent care: IV calcium gluconate (decreases the potential for a cardiac event)
Q15 HYPOcalcemia
A low calcium <9.0
Section 2: Clinical, Nursing, Interventions (Q16–Q29)
Question & Answer
Q16 Clinical manifestations for HYPOcalcemia
A NEUROMUSCULAR Changes (important) -Trousseau sign: muscle spasm when BP cuff is inflated
-Chvostek sign: facial twitching when they tap on the face -Paresthesia: tingling around the lips - HR
& ECG changes
Q17 Nursing interventions HYPOcalcemia
A Drug therapy: IV calcium, Oral calcium & vitamin D -Monitor ECG changes
Q18 HYPERcalcemia
A high calcium >10.5
Q19 Causes of HYPERcalcemia
A Malignancy (bone malignancy)
Q20 clinical manifestations of HYPERcalcemia
A -ECG changes (important) -Neuromuscular changes (important): severe muscle weakness,
decreased DTR
Q21 Nursing interventions HYPERcalcemia
A -NS administration (rehydrating the pt) - IF HYDRATION IS NOT AN ISSUE= loop diuretic
administration - Calcitonin administration: helps bring down calcium level
Q22 HYPOmagnesemia
A low magnesium <1.3 magnesium= mellow
Q23 Clinical manifestations for HYPOmagnesium
A ECG changes that can be fatal (important) -Hyperactice DTR, numbness and tingling
Q24 Nursing interventions for HYPOmagnesium
A -magnesium suflate IV -Seizure precautions -Treat hypocalcemia
