NR 601 WEEK 3 PSYCHIATRIC DISORDERS AND
SCREENING 2026 FINAL PAPER REVIEW
QUESTIONS ANSWERS BUNDLED PRACTICE
COLLECTION
◉ Basic Laboratory Interpretation.
Answer: Complete Blood Count
Comprehensive Metabolic Panel (CMP)
Thyroid Function Tests
Vitamin B12 Level
Vitamin D Level
Toxicology Screen
Urinalysis (UA)
◉ Basic Laboratory Interpretation: Complete Blood Count.
Answer: -measures RBCs, WBCs, hemoglobin, hematocrit, and
platelets
-includes a differential of the WBCs
-In mental health, the CBC is used to rule out medical conditions that
may present with symptoms that can be attributed to both medical
and psychiatric diagnoses
,• Ex: rule out anemia as a cause for depressive symptoms and
fatigue
• Ex: rule out infection as a cause of acute mental status changes
RBCs: 4.5-6.0 million/microliter
Hemoglobin: 12-18 grams/100 mL
Hematocrit: 38%-48%
Reticulocytes: 0%-1.5%
WBCs (total): 5000-10,000/microliter
Neutrophils: 55%-70%
Eosinophils: 1%-3%
Basophils: 0.5%-1%
Lymphocytes: 20%-35%
Monocytes: 3%-8%
Platelets: 150,000-300,000/microliter
◉ Basic Laboratory Interpretation: Comprehensive Metabolic Panel
(CMP).
Answer: common blood test used to determine general health status
-fluid and electrolyte balance, status of the body's metabolism, liver
function, and kidney function
-used to monitor the effects of medications, such as antipsychotics,
on liver function and glucose levels
,-rule out medical conditions that could cause symptoms
• Ex: changes in mood or cognition
Sodium (Na+): 136-145 mEq/L
Postassium (K+): 3.5-5.0 mEq/L
Chloride (Cl-): 95-105 mEq/L
Bicarbonate (HCO3-): 22-28 mEq/L
Calcium, serum (Ca 2+) 8.4-10.2 mg/dl
Glucose, serum Fasting: 70-110 mg/dl; 2-h postprandial: <120mg/dl
Cholesterol, serum: REC<200 mg/dl
Total Protein 6.0-7.8 g/dl
Albumin 3.5-5.5 g/dl
-Kidney Tests
• Creatinine, serum 0.6-1.2mg/dl
• Urea nitrogen, serum (BUN) 7-18mg/dl
-Liver Tests
• Alanine aminotransferase (ALT), serum: 8-20 U/L
• Aspartate aminotransferase (AST), serum: 8-20 U/L
• Bilirubin, serum (adult) Total//Direct: 0.1-1.0 mg/dl // 0.0-0.3
mg/dl
• Phosphatase (alkaline), serum: 20-70 U/L
, ◉ Basic Laboratory Interpretation: Thyroid Function Tests (TFTs).
Answer: used to rule out thyroid disorders as a cause for symptoms
• symptoms related to thyroid disorders include anxiety,
restlessness, depression, mood swings, sleeping difficulties,
difficulties with concentration, short-term memory lapses, and lack
of mental alertness
Normal TFT levels
TSH: 0.4-4.5 mIU/L
T3: 100-200 ng/dL
T4: 5-11 ug/dL
◉ Basic Laboratory Interpretation: Vitamin B12 Level.
Answer: Deficiency of vitamin B12 can affect mood and other brain
functions
-psychiatric symptoms associated with B12 deficiency include
depression, mania, psychotic symptoms, and cognitive impairment
normal: 190-950 picograms/mL
• 200-300/mL indicates a borderline level with a possible need for
additional testing
◉ Basic Laboratory Interpretation: Vitamin D Level.
