Study Notes

Acid-Base Balance

Normal pH range: 7.35-7.45; acidosis occurs below 7.35 and alkalosis above 7.45.
PCO2 normal range: 35-45 mmHg; changes indicating respiratory disorders when opposite to pH.
Respiratory acidosis: pH < 7.35, PCO2 > 45 mmHg.
Respiratory alkalosis: pH > 7.45, PCO2 < 35 mmHg.
HCO3 normal range: 22-26 mEq/L; indicates metabolic disorders when in the same direction as pH.

Metabolic Acidosis & Alkalosis

Metabolic acidosis: Decreased pH, PCO2, and HCO3.
Metabolic alkalosis: Increased pH, PCO2, and HCO3.

Fluid Balance Disorders

Hypovolemia:
- Manifestations: tachycardia, tachypnea, dehydration, low blood pressure, orthostatic hypotension.
- Management: IV isotonic solution (0.9% normal saline).
- Nursing interventions: fall precautions, assist with ambulation, monitor weight, skin turgor assessment.
Hypervolemia:
- Manifestations: hypertension, rapid peripheral pulses, respiratory symptoms, pulmonary crackles.
- Management: fluid restriction.
- Complication: weight gain of 2 lbs in 3 days.
- Nursing interventions: monitor weight, strict intake/output monitoring, fall precautions.

Electrolyte Imbalances

Hypokalemia:
- Serum potassium level: < 3.5 mEq/L.
Hyperkalemia:
- Manifestations: ECG changes (tall peaked T waves), abdominal cramps, muscle weakness, diarrhea, arrhythmias.
- Interventions: calcium gluconate IV, calcium administration, IV dextrose with insulin.
- Causes: inhibited aldosterone secretion leading to cardiac dysrhythmias.
Hypomagnesemia:
- Level < 1.6 mEq/L; common cause is diarrhea.
- Nursing management includes referral to alcohol abstinence programs.
Calcium Levels:
- Normal range: 8.2-10.2 mg/dL; affects heart sensitivity.
Hypocalcemia:
- Manifestations: smooth muscle spasms, positive Trousseau's and Chvostek's signs.
Hypercalcemia:
- Manifestations: decreased deep tendon reflexes.
- Management: IV bisphosphonates and calcitonin.
Hyponatremia:
- Causes: diuretics; manifestations include seizure potential.
- Nursing interventions focus on seizure precautions.
Hypernatremia:
- Management: limit sodium intake and monitor daily weight.
Hypochloremia:
- Manifestations include irritability, hypotension, and tetany.

Metabolic Acidosis Management

Treatment focuses on addressing underlying causes and using antidiarrheals.
Nursing interventions: monitor hemodynamic status, especially cardiac output.

Urinary Disorders

UTI:
- Manifestations: dysuria and dark, foul-smelling urine.
- Nursing intervention: increase fluid intake to 2-3 liters daily.
Urinary Incontinence:
- Characterized by involuntary or uncontrolled loss of urine.

Reproductive Health

Bladder Cancer: Major risk factor is smoking.
Dysmenorrhea: Treated with combined oral contraceptives (estrogen and progesterone).
Cervical Cancer: Diagnosed through routine pap smears; treatment typically involves colposcopy and biopsy.
BPH:
- Manifestations: weak urine stream, decreased force.
- Diagnosis: digital rectal exam and urinalysis.
- Medications: anticholinergics.
Prostate Cancer: Risk increases with age; teaching includes signs of infection.
Testicular Cancer: Normal finding includes darker testicles.
HPV: Associated with increased risk of cervical cancer and diagnosed via pap tests and colposcopy. Teaching emphasizes vaccination for prevention.

STI Treatment

Genital Herpes: Manifestations include fever and headache; avoid medication during pregnancy.
Chlamydia: Can be asymptomatic but may lead to dysuria.
Gonorrhea: Risk factors include low socioeconomic status and history of STIs.

Miscellaneous

Menopause: Classified after 12 months without vaginal bleeding.
Urolithiasis Complication: Kidney stones may lead to pyelonephritis.
TURP Procedure: Surgery to remove part of the prostate due to BPH.
Cervical Dysplasia: Abnormal cervical cell growth typically linked to HPV.
Condylomata Acuminata: Anogenital warts caused by HPV.
Syphilis Treatment: Managed with penicillin.
