The Molecular Blueprint of Nursing Flashcards

Flashcards based on lecture notes covering the molecular foundations of nursing, biomolecules, cellular respiration, blood glucose regulation, acid-base balance, organ waste metrics, and pharmacological actions.

What is biochemistry defined as in the context of clinical observations?

Biochemistry is the scientific foundation that decodes clinical observations into actionable interventions.

What is the underlying cellular event in a patient presenting with severe dehydration?

Severe fluid and electrolyte imbalance at the cellular level.

What is the focus and nursing application of Clinical Biochemistry 14?

Focus: Lab-based diagnosis. Nursing Application: Monitoring disease progression and organ function.

What is the focus and nursing application of Enzymology?

Focus: Biological catalysts. Nursing Application: Interpreting clinical laboratory test results.

What is the composition, primary function, and clinical relevance of carbohydrates?

Composition: Carbon, hydrogen, oxygen. Primary Function: Energy production and cellular recognition. Clinical Relevance: Maintenance of blood glucose levels; digestion/absorption tracking.

What is the composition, primary function, and clinical relevance of lipids?

Composition: Fats / Insoluble compounds. Primary Function: Cell membrane formation, hormone production. Clinical Relevance: Long-term energy storage, insulation, and organ protection.

What is the composition, primary function, and clinical relevance of proteins?

Composition: Amino acids. Primary Function: Enzymatic action, substance transport. Clinical Relevance: Critical for wound healing, immune response, and tissue repair.

What is the composition, primary function, and clinical relevance of nucleic acids?

Composition: DNA/RNA structures. Primary Function: Genetic information storage. Clinical Relevance: Directing protein synthesis and cellular division.

What are the primary functions of water, vitamins, and electrolytes in the body?

Water maintains blood volume and temperature; vitamins act as organic co-factors; electrolytes are charged minerals regulating heart rhythm and acid-base balance.

What is the chemical equation for cellular respiration in a healthy state?

$$\text{Glucose} + \text{Oxygen} \rightarrow \text{Carbon Dioxide} + \text{Water} + \text{ATP}$$

What is ATP and what cellular processes does it fuel?

ATP is the cellular currency used for muscle contraction, nerve transmission, and cell repair.

What is the Hypoxic Cascade?

A critical reduction in ATP and energy production that leads directly to tissue damage, underlying conditions like hypoxia, shock, severe anemia, sepsis, and respiratory failure.

How do insulin and glucagon regulate glucose levels?

Insulin pushes glucose into cells, while glucagon releases stored glucose.

What are the biochemical state, clinical symptoms, and nursing focus for hypoglycemia?

Biochemical State: Critical deficit of blood glucose. Clinical Symptoms: Sweating, tremors, intense hunger, dizziness, palpitations, confusion, and weakness. Nursing Focus: Immediate capillary glucose check and rapid carbohydrate/glucose administration.

What are the biochemical state, clinical symptoms, and nursing focus for hyperglycemia?

Biochemical State: Toxic accumulation of blood glucose. Clinical Symptoms: Increased thirst, frequent urination, profound fatigue, blurred vision, and slow wound healing. Nursing Focus: Insulin administration, diet monitoring, and long-term complication prevention.

What is the normal blood pH level and the role of the Bicarbonate Buffer System?

Normal blood pH is $7.4$. The Bicarbonate Buffer System acts as the body's primary molecular shock-absorber against harmful pH shifts.

What triggers Respiratory Acidosis?

It is triggered by excess Carbon Dioxide retention (e.g., Respiratory Failure).

What triggers Metabolic Acidosis?

It is triggered by loss of bicarbonate, specifically mapped to clinical events like severe diarrhea or diabetic ketoacidosis.

What triggers Metabolic Alkalosis?

It is triggered by loss of stomach acid, specifically mapped to clinical events like severe vomiting.

What specific electrolytes are replaced during IV fluid administration for dehydration, dengue fever, or diarrhea?

Sodium, Potassium, Calcium, and Chloride.

Why is oxygen therapy essential for cellular respiration?

It supplies the mandatory catalyst for ATP production, preventing cells from shifting to anaerobic, tissue-damaging states.

What waste product and clinical metrics are associated with the liver?

Waste Product: Bilirubin. Clinical Metric: Liver enzymes and Bilirubin labs.

What waste products and clinical metrics are associated with the kidneys?

Waste Products: Urea, Creatinine, excess electrolytes, water. Clinical Metric: Blood Urea Nitrogen (BUN), Creatinine levels.

What waste product and clinical metric are associated with the lungs?

Waste Product: Carbon Dioxide. Clinical Metric: Arterial Blood Gases (ABGs).

What waste product is filtered by the skin?

Small amounts of metabolic waste via sweat.

What specific inputs are necessary for tissue building and repair?

Protein synthesis (tissue building), Vitamin C & Zinc (collagen formation/immunity), Oxygen (cellular repair), and strict blood glucose control.

How do poor nutrition or high blood glucose affect surgical healing?

They strictly halt protein synthesis, resulting in delayed surgical healing.

What are the pharmacological actions of antibiotics, diuretics, and anticoagulants?

Antibiotics: Interfere with bacterial biochemical processes. Diuretics: Force water and electrolyte excretion. Anticoagulants: Block specific blood clotting pathways.
