PEARLS

Question 1

high heart rate, low BP

Answer 1

think bleed-dehydration

Question 2

flat jugular veins when supine

Answer 2

think bleed-dehydration or HHNK

Question 3

hot skin in a shock pt

Answer 3

think SEPTIC shock, look for source
- commonly will present with open wound
- can present in nursing home pts
- bacteria in bloodstream via lymph system to be septic
- temp down = late sign in septic shock
- cause is always bacterial

Question 4

female pt on birth control and/or smoking w/ SOB

Answer 4

think PE
- NR classically uses 35 y/o female smoker
- predisposing factors: travel, long period of inactivity, recent surgery, cancer
- PE mimics RSF (blocks blood flow up through the lungs, blood backs up causing edema & JVD)

Question 5

hives, laryngeal edema

Answer 5

think allergic or anaphylaxis
- stridor usually exists with anaphylaxis related throat swelling
- laryngeal edema also caused by trauma/localized infection (Ludwig’s angina)
- hive is a swollen capillary bed
- urticaria = hive related itching
- IgE = antibody responsible for anaphylaxis (histamine from mast cells, IgE attaches, causes them to burst)

Question 6

cool, clammy skin

Answer 6

think shock (sympathetic response)

Question 7

sudden onset of vomiting/diarrhea after eating

Answer 7

think allergic or anaphylactic shock
- food poisoning typically takes ~ 12 hours, allergy/anaphylaxis is quicker

Question 8

cool, clammy skin above & warm, dry skin below w/ low BP & low HR, think…

Answer 8

neurogenic shock (does not have to be trauma)
- spinal shock is temporary (difference between spinal and neurogenic)
- neurogenic shock can come w/ any disruption in blood flow (not just trauma)

Question 8

getting pt to the hospital is not enough…

Question 16

pt states “feels like my heart is beating out of my chest,” think…

Answer 16

SVT
- can/will result in LSF, backup blood to lungs
- CHAP = stable or unstable
- Tx stable = adenosine (6mg/12mg, save last 12 for hospital)
- Tx unstable = cardiovert @ 100 J

Question 17

Wolff Parkinson White Syndrome presents with (on 12-lead)…

Answer 17

delta wave on ECG, slurred P wave line into QRS

Question 18

crushing substernal chest pain, think…

Answer 18

MI

- other signs = toothache, bellyache

Question 19

sudden onset SOB, think…

Answer 19

PE

Question 20

JVD, think…

Answer 20

RSF
- PE, tension pneumo, cardiac tamponade, COPD

ectopic pregnancy
- having tubal ligation increases the risk, but used to throw people off on test

Question 23

tall, skinny males with SOB, think…

Answer 23

spontaneous pneumo
- closed pneumo, often presents with history of smoking
- can occur in pts with Hx of COPD

MI, stroke, aneurism

s/s of lightheadedness, breathlessness, weakness, headache, nausea, vomiting could indicate what condition

Answer 34

acute mountain sickness - occurs at 6600 ft, least serious of the altitude related illnesses - Tx includes remaining where you are and it will subside or go to lower elevation, fluid admin recommended, can be treated with diuretic (acetazolamide) - high respirations lead to respiratory alkalosis

Question 35

s/s of progressive weakness, fatigue, decreased appetite, weight loss, hyperpigmentation of skin, vomiting, diarrhea could indicate what condition

Answer 35

addison's disease (hypoadrenalism) - adrenal disease -> hypoadrenalism -> possibly autoimmune disease (can also be caused by an intense stressor on the system) -> cessation of adrenal gland function - die from cardiopulmonary collapse

Answer 36

allergies and anaphylaxis - Tx for allergy run w/o airway compromise = Benadryl - Tx for anaphylaxis = epi 1:1000 (antibody driver behind this reaction is IgE, which is attached to mast and mobile mast cells, anaphylaxis is type 1 allergic reaction)
