following first sex
• Prostate cancer= risks high fat and black
o Findings= urinary hesitancy, recurrent bladder infection, urinary retention, blood in
urine and semen (late), significant residual urine after voiding a small amt of urine
o PSA= greater than 4 indicates possible prostate disease, instruct pt to get prostate
screening after 50, insure psa is assess prior to DRE
o Meds= leuprolide
Ch. 93 Pain management for pt who have cancer
• Palliative cancer pain management provides comfort and reduce pains rather than curing
cancer, goal of palliative pain management is to reduce pain to improve qol
• Meds= nonopioid, opioids, antidepressant (reduce depression, decrease neuropathic pain),
anticonvulsants, corticosteroids (reduce swelling), skeletal muscle relaxants (muscle
spasms), systemic local anesthetics (infusion pump), topical local anesthetic (lidocaine
patch), epidural or intrathecal, regional nerve blocks
• Alternatives= tens (low voltage electrical impulses), heat or cold, pressure, massage or
vibration, acupuncture
Ch. 94 Anesthesia and Moderate Sedation
• General anesthesia= inhalation (NO), IV anesthetic (benzos, Propofol)
o Phases
§ Induction= initiation of IV access, preop meds given, secure airway
§ Maintenance= performance of surgery, airway maintenance
§ Emergence= completion of surgery, removal of assistive airway device
o Meds= opioids, benzos, antiemetics (decrease postanesthetic n/v), anticholinergics,
sedatives, neuromuscular blocking agents
o Complications
§ Malignant hyperthermia= tachy first, dysrhythmias, muscle rigidity,
hypotension, tachypnea, skin mottling, cyanosis, myoglobinuria (protein in
urine)
• Stop surgery, admin IV dantrolene (muscle relaxant), admin 100% O2,
obtain ABGs, infuse iced IV NaCl, apply cooling blanket
• Moderate sedation= admin sedatives/opioids to point where pt relaxes enough that surgeon
can perform minor procedure w/o discomfort for pt, yet pt retains protective reflexes (gag
reflex), is easily arousable and maintains patent airway
• Pre=NPO 6hr prior to procedure, clear liquids up to 2hr b/f surgery, verify pt signed
informed consent, remove dentures
• Intra=assess loc, cardiac rhythm, respiratory status and vitals
• Post= monitor and document vitals and loc until pt is fully awake, assessment criteria return
to pre-sedation levels
o Discharge= vitals stable for 30-90 min, ability to tolerate orals fluids, ability to
urinate, no N/V SOB or dizzy
§
Ch. 95 Preop Nursing Care
• Verify that informed consent is completed, signed, and witnessed, scheduled meds (antihtn,
anticoags, antidepressants) can be held until after surgery, ensure pt remains NPO for 6hrs
for solids and 2hrs for clear liquids b/f surgery, prophylactic antibiotics admin w/I 1hr of
surgical incision
• Informed consent= responsibility of PROVIDER to obtain consent after discussing risks and
benefits of procedure, the nurse is NOT to obtain consent for provider UNDER ANY
CIRCUMSTANCE, nurse can clarify info that remains unclear but NOT provide any new
info, NURSE ROLE is to witness pt signing of consent form after pt acknowledges
understanding of procedure and to notify provider if pt has more questions or appears to not
understand info
o Must be 18 or emancipated, mentally capable of understanding risk, NOT under
influence of meds that affect decision making or judgment
Ch. 96 PostOp Nursing Care
• Airway=assess blood o2 saturation, assess respiratory pattern, rate, and depth, assess
symmetry of breath sounds, auscultate lung sounds, suction accumulated secretions
• Circulation= observe for internal bleeding, assess for hypervolemia and hypovolemia,
assess skin color, temp, sensation, assess and compare peripheral pulses, monitor ekg,
monitor fluid and electrolyte balance
• Vitals= obtain vitals until stable
• I&O= review I& O, urine output less than 30 can indicate hypovolemia
• Surgical wound= check dressings and admin pain meds
• Discharge= stable vitals, no evidence of bleeding, return of reflexes, minimal or absent n/v,
wound drainage that is minimal to moderate, urine output at least 30mL/ hr
