Master Fundamentals of Nursing for Your 2025 Nursing Exams
Hello, dear nursing students and exam aspirants. We are continuing our journey to help you prepare for the AIIMS NORCET 9.0, KGMU, BTSC, or Raj CHO/NHM nursing exams in 2025. Today, on Day 29, we will focus on Fundamentals of Nursing, a topic you need to master. Fundamentals of nursing form the foundation of patient care, covering essential skills like assessing vital signs, interpreting diagnostic tests, and managing fluid balance. At logyanlo.in, we are here to support you with our Day 29 Practice Test, designed to help you excel in this essential subject.
In this guide, we will cover Fundamentals of Nursing in detail, including vital signs like temperature, respiration, pulse, and blood pressure, diagnostic tests like ABG analysis and applied ABG, and concepts of fluids and electrolytes, as well as fluid balance and imbalance. These topics are high-yield for exams like AIIMS NORCET 9.0, KGMU, and Raj CHO/NHM, often making up 10–15% of the questions. Let us dive in and take your exam prep to the next level.
Why Fundamentals of Nursing is Essential for Nursing Exams
Fundamentals of Nursing focuses on the basic principles and skills needed to provide safe and effective patient care. This topic is a major focus in exams like AIIMS NORCET 9.0, KGMU, BTSC, and Raj CHO/NHM, testing your ability to assess patients, interpret diagnostic tests, and manage fluid imbalances. Here is why this subject matters:
- Core Knowledge: It covers vital signs, diagnostic tests, and fluid balance, which are foundational to nursing practice.
- Exam Focus: Questions often test your knowledge of normal vital sign ranges, ABG interpretation, and electrolyte imbalances.
- Clinical Skills: Skills like measuring blood pressure and analyzing ABGs are vital for patient assessment.
- Score Booster: A strong performance in this section can significantly improve your overall exam score.
At logyanlo.in, our Day 29 Practice Test is crafted to help you master these concepts and feel confident heading into the 2025 exams.
Key Concepts in Fundamentals of Nursing for Your Exam Prep
Let us explore the core topics of Fundamentals of Nursing that you need to know for your AIIMS NORCET 9.0, KGMU, BTSC, or Raj CHO/NHM exams. We will focus on nursing responsibilities and exam-relevant points.
Vital Signs: Temperature, Respiration, Pulse, Blood Pressure
Vital signs are key indicators of a patient’s physiological status, often the first step in assessing health.
Temperature:
- Normal Range: 36.5–37.5°C (97.7–99.5°F).
- Methods:
- Oral: Most common, 0.5°C higher than axillary.
- Axillary: Least invasive, 0.5°C lower than oral.
- Tympanic: Quick, reflects core temperature.
- Abnormalities:
- Fever (>38°C): Indicates infection or inflammation.
- Hypothermia (<35°C): Seen in shock or exposure.
Respiration:
- Normal Range: 12–20 breaths/min (adults).
- Assessment:
- Rate: Count breaths per minute.
- Depth: Shallow, normal, or deep.
- Pattern: Regular or irregular (e.g., Cheyne-Stokes in heart failure).
- Abnormalities:
- Tachypnea (>20 breaths/min): Seen in fever, anxiety.
- Bradypnea (<12 breaths/min): Seen in opioid overdose.
Pulse:
- Normal Range: 60–100 beats/min (adults).
- Assessment:
- Rate: Count beats per minute.
- Rhythm: Regular or irregular.
- Strength: Strong, weak, or thready.
- Sites: Radial (most common), carotid, brachial.
- Abnormalities:
- Tachycardia (>100 beats/min): Seen in fever, shock.
- Bradycardia (<60 beats/min): Seen in hypothermia.
Blood Pressure:
- Normal Range: 90/60–120/80 mmHg.
- Assessment:
- Systolic: Pressure during heart contraction.
- Diastolic: Pressure during heart relaxation.
- Use a sphygmomanometer and stethoscope.
- Abnormalities:
- Hypertension (>140/90 mmHg): Risk for stroke.
- Hypotension (<90/60 mmHg): Seen in shock, dehydration.
Nursing Responsibilities:
- Measure vital signs accurately, using appropriate techniques (e.g., ensuring cuff size is correct for BP).
- Monitor trends, like a rising temperature indicating infection, and report abnormalities.
- Educate patients on factors affecting vital signs, like avoiding caffeine before BP measurement.
Exams often test your knowledge of normal ranges, like a pulse of 60–100 beats/min in adults.
Diagnostic Tests: ABG Analysis
Arterial Blood Gas (ABG) analysis measures blood pH, oxygen, and carbon dioxide levels to assess respiratory and metabolic function.
Key Components:
- pH: 7.35–7.45 (normal), indicates acid-base balance.
- PaO2: 75–100 mmHg, measures oxygen in arterial blood.
- PaCO2: 35–45 mmHg, measures carbon dioxide, reflects ventilation.
- HCO3-: 22–26 mEq/L, measures bicarbonate, reflects metabolic status.
- Base Excess: -2 to +2 mEq/L, indicates metabolic acid-base imbalance.
Steps for Analysis:
- Step 1: Check pH (acidotic <7.35, alkalotic >7.45).
- Step 2: Identify primary disorder:
- If PaCO2 is abnormal, it’s respiratory.
- If HCO3- is abnormal, it’s metabolic.
- Step 3: Check for compensation (e.g., high HCO3- in respiratory acidosis).
Nursing Responsibilities:
- Prepare the patient for ABG sampling, explaining the procedure (arterial puncture, usually radial artery).
- Monitor the puncture site for bleeding or hematoma post-procedure.
- Report critical values immediately (e.g., pH <7.2 or PaO2 <60 mmHg).
Exams often test your understanding of ABG components, like PaCO2 reflecting ventilation status.
Applied ABG
Applied ABG involves interpreting ABG results to identify acid-base disorders and their causes.
Disorders:
- Respiratory Acidosis:
- pH <7.35, PaCO2 >45 mmHg.
- Cause: Hypoventilation (e.g., COPD, opioid overdose).
- Respiratory Alkalosis:
- pH >7.45, PaCO2 <35 mmHg.
- Cause: Hyperventilation (e.g., anxiety, fever).
- Metabolic Acidosis:
- pH <7.35, HCO3- <22 mEq/L.
- Cause: Diabetic ketoacidosis, diarrhea.
- Metabolic Alkalosis:
- pH >7.45, HCO3- >26 mEq/L.
- Cause: Vomiting, diuretic use.
Compensation:
- Respiratory compensation: Kidneys adjust HCO3- (takes days).
- Metabolic compensation: Lungs adjust PaCO2 (takes minutes to hours).
Nursing Responsibilities:
- Interpret ABG results, like identifying respiratory acidosis in a COPD patient with PaCO2 of 50 mmHg.
- Monitor for signs of acid-base imbalance, like Kussmaul respirations in metabolic acidosis.
- Administer interventions as ordered, like oxygen therapy for respiratory acidosis.
Exams often test your ability to identify disorders, like metabolic acidosis with low HCO3-.
Fluids and Electrolytes
Fluids and electrolytes maintain homeostasis, supporting cellular function and organ systems.
Key Electrolytes:
- Sodium (Na+): 135–145 mEq/L, regulates fluid balance.
- Hyponatremia (<135 mEq/L): Seen in SIADH, causes confusion.
- Hypernatremia (>145 mEq/L): Seen in dehydration, causes thirst.
- Potassium (K+): 3.5–5.0 mEq/L, regulates cardiac and muscle function.
- Hypokalemia (<3.5 mEq/L): Seen in diuretic use, causes arrhythmias.
- Hyperkalemia (>5.0 mEq/L): Seen in renal failure, causes peaked T waves.
- Calcium (Ca2+): 8.5–10.5 mg/dL, supports bone health and muscle contraction.
- Hypocalcemia (<8.5 mg/dL): Seen in vitamin D deficiency, causes tetany.
- Hypercalcemia (>10.5 mg/dL): Seen in hyperparathyroidism, causes lethargy.
- Magnesium (Mg2+): 1.5–2.5 mEq/L, supports nerve and muscle function.
- Hypomagnesemia (<1.5 mEq/L): Seen in alcoholism, causes tremors.
- Hypermagnesemia (>2.5 mEq/L): Seen in renal failure, causes bradycardia.
Nursing Responsibilities:
- Monitor electrolyte levels, reporting abnormalities like hyperkalemia (>5.0 mEq/L).
- Administer IV fluids or electrolyte replacements as ordered (e.g., potassium chloride for hypokalemia).
- Educate patients on dietary sources, like bananas for potassium.
Exams often test your knowledge of normal ranges, like sodium at 135–145 mEq/L.
Fluid Balance and Imbalance
Fluid balance maintains the body’s hydration status, while imbalances can lead to serious complications.
Fluid Compartments:
- Intracellular Fluid (ICF): 60% of body water, inside cells.
- Extracellular Fluid (ECF): 40% of body water, includes:
- Intravascular (plasma).
- Interstitial (between cells).
Fluid Imbalances:
- Dehydration (Fluid Volume Deficit):
- Causes: Vomiting, diarrhea, excessive sweating.
- Signs: Thirst, dry mucous membranes, low BP, high pulse.
- Fluid Overload (Fluid Volume Excess):
- Causes: Heart failure, excessive IV fluids.
- Signs: Edema, crackles in lungs, high BP.
Assessment:
- Daily weight: 1 kg = 1 liter of fluid.
- Intake and output: Normal output 1–2 liters/day.
- Skin turgor: Pinched skin returns slowly in dehydration.
Nursing Responsibilities:
- Monitor intake and output, ensuring balance (e.g., 2 liters in, 2 liters out).
- Assess for signs of imbalance, like edema in fluid overload, and report promptly.
- Administer fluids as ordered, like isotonic saline (0.9% NaCl) for dehydration.
Exams often test your understanding of fluid imbalances, like signs of dehydration (dry mucous membranes).
