NUR1023 Final Exam – NUR1023, Florida State
College at Jacksonville (FSCJ), Complete Exam
Study Guide and Key Concepts Review
Introduction:
This document covers essential nursing concepts for the NUR1023
final exam, including fluid and electrolyte imbalances, medication
administration, pain management, laboratory values, and patient
care interventions. It also includes key topics such as infection
control, nutrition, developmental stages, and diagnostic procedures,
making it a comprehensive review for exam preparation.
Exam Questions and Answers:
causes of Hypernatremia ---Correct precise answer---Fluid
deprivation, lack of fluid consumption, diarrhea, excess insensible
water loss, excess water loss, rapid or excessive administration of
sodium-containing IV solutions
Nursing interventions for Hyper/Hyponatremia ---Correct precise
answer---Fluid replacement/ restriction
Low-Sodium dietary restrictions
Diuretics
,Potassium (K+) does what in the body ---Correct precise answer----
Controls intracellular osmolality Regulator of cellular enzyme
activity
-Role in the transmission of electrical impulses in nerve, heart,
skeletal, intestinal, and lung tissue;
-Regulated by aldosterone Eliminated by the kidneys
-Additional regulation via transcellular shift between the ICF and
ECF compartments
hyperkalemia S/SX ---Correct precise answer---A variety of cardiac
irregularities may result, including cardiac arrest if hyperkalemia
is not corrected
V-fib, v-tach, deadly arrhythmias
Hyperkalemia- it can lead to irregular heartbeat (arrhythmia),
muscle weakness, fatigue, nausea, and in severe cases, even cardiac
arrest
Hyperkalemia ---Correct precise answer---Excess potassium may
result from renal failure, hypoaldosteronism, or the use of certain
medications such as potassium chloride, heparin, angiotensin-
converting enzyme (ACE) inhibitors, nonsteroidal antiinflammatory
drugs (NSAIDs), and potassium-sparing diuretics.
,hypokalemia S/SX ---Correct precise answer---muscle weakness,
cramps, irregular heartbeat, and fatigue, primarily affecting muscle
function and heart rhythm due to potassium's role in electrical
signaling within the body.
hypokalemia ---Correct precise answer----Potassium may be lost
through vomiting, gastric suction, alkalosis, or diarrhea, or as the
result of the use of diuretics.
-When the extracellular potassium level falls, potassium moves
from the cell, creating an intracellular potassium deficiency.
Sodium and hydrogen ions are then retained by the cells to
maintain isotonic fluids.
Foods that have potassium ---Correct precise answer---Fruits such
as bananas, dried apricots, prunes, raisins, kiwi
Veggies such as potatoes, spinach, tomatoes, broccoli, beans, lentils
Milk, yogurt, all meat and fish
Leading food sources: fruits and vegetables, dried peas and beans,
whole grains, milk, meats Lost via kidneys, stool, sweat, emesis
nursing interventions for hyper/hypokalemia ---Correct precise
answer----administer PO hypo. Do not crush pills. Can piggyback
K+. NO STRAIGHT PUSH
-limit potassium if hyperkalemic.
-Discontinuing diuretics,
, -monitor potassium levels.
Magnesium (Mg+) ---Correct precise answer----It Activates enzyme
-Major role in synthesis of carbohydrates, protein and dna by
stabilizing their structure and allowing them to function properly,
particularly in reactions related to ATP
-Role in electricity in the heart, muscle and nerves
Hypomagnesemia causes ---Correct precise answer---Malnutrition
Diuretic therapy
Syndrome of inappropriate antidiuretic hormone secretion (SIADH)
Small bowel bypass surgery
Hypercalcemia (increase in calcium causes decrease in magnesium)
Hypomagnesemia S/Sx ---Correct precise answer---muscle
weakness or spasms
Tremors
Tetany
Seizures
cardiac arrhythmias
change in mental status
hyperactive deep tendon reflexes (DTRs)
