QUESTIONS AND CORRECT ANSWERS
Question:
1. Hyperosmolar Dehydration Water Shift
Answer:
Water moves from tissue cells into hyperosmolar blood, causing cellular dehydration.
Question:
2. Compensated Metabolic Acidosis ABG Pattern
Answer:
Low pH (<7.35), low HCO■■ (<22 mEq/L), and low PaCO■ (<35 mm Hg).
Question:
3. Hyperkalemia with Peaked T Waves Priority
Answer:
Place client on continuous cardiac monitoring and notify provider immediately.
Question:
4. Hypokalemia Findings
Answer:
Flattened T waves, U waves, ST depression, and muscle weakness.
Question:
5. Wernicke Encephalopathy Prevention in Alcoholism
Answer:
Administer IV thiamine (Vitamin B1) before giving glucose.
Question:
6. Second Line of Defense Example
Answer:
Mast-cell histamine release producing local acute inflammation.
Question:
7. Humoral Adaptive Immunity Mechanism
Answer:
B lymphocytes differentiate into plasma cells that produce specific antibodies.
Question:
8. Anaphylactic Shock First-Line Treatment
Answer:
Intramuscular (IM) epinephrine.
Question:
9. Sepsis Definition
, Answer:
A dysregulated systemic inflammatory response triggered by a confirmed infection.
Question:
10. Systemic Lupus Erythematosus (SLE) Tissue Injury
Answer:
Deposition of autoantibody-antigen immune complexes in blood vessels and tissues.
Question:
11. Septic Shock Priority Management
Answer:
Activate sepsis protocol, restore perfusion with fluids/vasopressors, and support oxygenation.
Question:
12. NSAID-Induced Peptic Ulcer Mechanism
Answer:
Inhibition of prostaglandin synthesis, decreasing protective gastric mucus and bicarbonate.
Question:
13. HIV Isolation Precautions
Answer:
Standard precautions (unless a co-infection requires specific transmission-based precautions).
Question:
14. Vancomycin-Resistant Enterococcus (VRE) Mechanism
Answer:
Alteration of the bacterial drug-binding target site.
Question:
15. Neutropenic Fever Priority Action
Answer:
Report immediately, obtain blood cultures, and administer prompt broad-spectrum antibiotics.
Question:
16. Iron-Deficiency Anemia Lab Pattern
Answer:
Microcytic cells (low MCV), low serum ferritin, and high TIBC.
Question:
17. Vitamin B12 Deficiency vs. Iron Deficiency
Answer:
Vitamin B12 deficiency presents with neurological signs (paresthesias, ataxia) and macrocytosis.
Question:
18. Severe Thrombocytopenia (<20,000/mm³) Safety
