NUR 211 Exam 1 Practice Questions and
Correct Answers
Donning PPE order ✅gown, mask/n95, face shield/goggles, gloves

Doffing PPE order ✅gloves, gown, leave patient's room and hand hygiene, face
shield/goggles, mask/n95, hand hygiene

Isotonic fluid examples ✅0.9% NS, D5W, 5% Dextrose in 0.225% Saline, LR

What do isotonic fluids do? ✅Expand plasma volume and cause cells to stay the same
size
-Replaces fluid lost due to nausea, vomiting, diarrhea, surgery
-increases extracellular fluid

Hypotonic fluid examples ✅0.45% NS, 0.225% NS, 0.33% NS, D5W, Plasma lyte 56

What do hypotonic fluids do? ✅Expand intracellular volume and cause cells to swell
-Give for dehydrated cell (DKA, HHS, DI, severe dehydration)
-don't give to patient with increased ICP, burns, or trauma

Hypertonic fluid examples ✅3% NS, 5% NS, D10W, 5% Dextrose in 0.9%NS, 5%
Dextrose in 0.45% NS, 5% Dextrose in LR

What do hypertonic fluids do? ✅Expand extracellular volume and cause cells to shrink
-Give for cellular edema such as cerebral edema, hyponatremia
-give it slowly in large vein, because it can cause fluid overload

What electrolytes are in LR? ✅Ca, K, Cl, Na

Colloids ✅are proteins, starches, and other large molecules such as Albumin,
Hetastarch, and Plasmalyte
-they expand plasma volume and draw fluids from the cells and tissues into the
intravascular space expanding circulating volume.

Endocrine system ✅-Affects most cell, organ, and body functions
-Closely linked with neurologic and immune systems
-Works by negative feedback system

Anti-Diuretic Hormone (Vasopressin) ✅-Controls fluid excretions by kidneys
-BP decreased -> body releases ADH so more water is in the blood -> this raises BP ->
blood osmo goes down -> urine we excrete is decreased and more concentrated

,Normal blood osmolality ✅275-295 mOsm/kg

Normal urine osmolality ✅500-850 mOsml/kg

Diabetes Insipidus (DI) ✅DRY DAN
-Hyposecretion of ADH or failure of kidney to respond appropriately to ADH
-Large Volume of dilute urine*
-Associated- Neurogenic or Nephrogenic- failure of kidney to respond appropriately to
ADH/ pee a lot
-polyurea/ nothing to do with blood sugar
-lose large volume of dilute urine 4-30 L in 24 hrs
-associated with neurogenic (hyposecretion- swelling of the brain, tumor in the brain,
infection of the brain, surgery) and nephrogenic (hypokalemia, hypercalcemia, meds like
lithium kidneys less responsive) become dehydrated
-Dry patient because urinating lots of water
-Hypernatremia can occur

DI Diagnostics ✅-Fluid Deprivation Test: 8-12 hrs or until 3-5% of body weight is lost/
person is weighed frequently
-Plasma and urine osmolality studies performed/ Inability for the specific gravity to
increase is characteristic of DI
-ADH test: measures how much ADH is in the blood usually used in combination with
other tests to determine what is causing the increase or decrease in ADH levels/ The
increase in urine osmolality and decreased urine output with this test is characteristic of
DI
-Urine specific gravity for DI is < 1.006
-Hold meds with sucrose or dextrose
-No heavily dyed foods before test

DI clinical manifestations ✅-UOP- 4-30 L/day
-Tachycardia
-Polydipsia
-Neuro changes
-Serum Osmolality ↑
-Urine Osmolality ↓
-Na levels ↑
-Hypotension
-Cardiovascular collapse
-dehydration in vascular bed
-Hypovolemia
-Decreased BP

DI Medical Management ✅-Replace Fluids: Free water- drinking water, water through
ng tube or iv fluids, d5w and water

, -Neurogenic (brain)- not enough ADH/ give IV vasopressin and desmopressin nasal
spray (it causes vasoconstriction so careful with heart patients), give thiazide diuretics
(increased sun sensitivity and hypokalemia and hypomagnesemia) Chloropropramide
-Thiazide Diuretics- makes desmopressin work harder
-Renal- have enough ADH just not responding/ give thiazide diuretics, mild salt
depletion, prostaglandin inhibitors- ibuprofen, aspirin- watch bleeding
-Prostaglandin inhibitors- help kidney respond better to diuretic and vasopressin
(indomethacin)

Which prescription for a client diagnosed with diabetes Insipidus should the nurse
question?
A. Monitor and record accurate intake and output
B. Check urine specific gravity
C. Restrict fluids to 100ml every 6 hours
D. Weigh the client daily ✅C

Syndrome of Inappropriate Anti-Diuretic Hormone (SIADH) ✅SOGGY SAM
-Excess excretion of ADH
-Concentrated urine
-Dilutional hyponatremia
-Fluid overload signs and symptoms
-Associated with neurological trauma, swelling of the brain, tumors of brain and lung,
pneumonia and meningitis (infections)
-Meds- vincristine, thiazide diuretics, phenothiazines, tricyclic antidepressants
-very concentrated urine, hang on to water, hyponatremia, fluid overload signs and
symptoms

SIADH Diagnostics ✅-Urine specific gravity > 1.032
-Serum Osmolality ↓
-Urine Osmolality ↑
-Serum Na ↓
-BUN/CR ↓

SIADH clinical manifestations ✅Fluid overload signs and symptoms hypertension,
crackles, jvd, edema, altered loc, seizures, coma, and death
-Na levels below 120- seizure, coma death

SIADH Medical Management ✅-Treat underlying cause
-Fluid Restrictions- no free water
-Na supplementation: Hypertonic solutions 3% NS- give in large vein/ central line/ give
slowly/ or Orally- like salt tabs
-Loop diuretics- furosemide- pull fluid to kidney and pee it out
-Electrolyte replacements
-least to most invasive procedures

SIADH Nursing Interventions ✅-Monitor cardiac and Neuro
