- tachypnea
- tachycardia
- hypoxia, hypocarbia
- cool, clammy skin
- MENTAL STATUS CHANGE
- pallor and cyanosis
- skin mottling
- SEVERELY low bp with narrowed pulse pressure
- High temp then it becomes low

- elevated inflammatory markers (WBC, plasma, C-rp, procalcitonin)
5
New cards
What should be completed within 3 hours of patient presentation/symptoms in septic shock?
- Obtain blood culture prior to admin of antibiotics
- Administer prescribed broad spectrum antibiotics
6
New cards
For septic shock, when do you initiate aggressive fluid resuscitation?
in patients with hypotension or elevated serum lactate (>4 mmol/L) → minimum initial fluid bolus of 30 mL/kg using crystalloid solutions
7
New cards
Since septic shock is most commonly caused by gram-negative bacteria, Joint Commission’s National Patient Safety Goals recommends the administration of
IV antibiotics that are effective against gram-negative bacteria within 1 hr of a septic shock diagnosis
8
New cards
What should be completed as soon as possible or within the first 6 hours of patient presentation/symptoms for septic shock
Begin vasopressor agents if hypotension is not improved (MAP < 65 mm Hg) after initial fluid resuscitation (norepinephrine)
9
New cards
For septic shock, if hypotension persists after initial fluid administration (MAP
Measure CVP (goal 8–12 mm Hg)

16
New cards
How do you prevent CAUTI
- strict aseptic technique during insertion

23
New cards
Advise clients taking fluoroquinolones or sulfonamides that
- sun-sensitivity is increased and sunburn is a risk for even dark-skinned individuals
- medications can precipitate in the renal tubules, so advise client to take these medications with a full glass of water and to increase fluid intake
- take with food

41
New cards
Amantadine
Antiviral, antiparkinsonian, anticholinergic
- it increases dopamine
- Monitor for discoloration of the skin that subsides when amantadine is discontinued
- pt might experience anxiety, confusion, and anticholinergic effects
- side effects: tremor, rigidity, bradykinesia
42
New cards
Dopaminergics
Levodopa - increases dopamine levels (leaves more in the brain)
- may be combined with carbidopa to decrease metabolism of levodopa (conserves)
- monitor for the wearing off phenomenon and dyskinesias (indicates the need to adjust the dosage or time of admin or the need for a medication holiday)
43

women who are postmenopausal should have a
very thin endometrium due to low levels of estrogen
a thicker lining warrants further investigation

interactions with others
63
New cards

Selective estrogen receptor modulators (SERMs): toremifene (tamoxifen and raloxifene)
Used in females who are at high risk for breast cancer or who have advanced breast cancer
• Suppress the growth of remaining cancer cells post-mastectomy or lumpectomy
• Tamoxifen has been found to increase the risk of endometrial cancer, DVT and
PE
• Raloxifene does not share these adverse effects
87
New cards
Chemotherapy and/or radiation can augment or replace a mastectomy, depending on several
factors
