SIMCLEX Questions attempt 1
Cushing reflex
a late sign following a head injury characterized by a triad consisting of -severe hypertension, bradycardia, and periods of apnea.
bronchiolitis
a respiratory infection that primarily affects the bronchioles found in the lower airways. It does primarily occurs in the winter.
why does prone positioning improve oxygenation ARDS
decreased atelectasis, mobilizes secretions, decreases pleural pressure.
metabolic acidosis
decreased pH in blood and body tissues as a result of an upset in metabolism
Rett Syndrome
disorder that results from a single-gene defect during development, in which there is a mutation on one of the X chromosomes, MECP2. The condition almost exclusively affects girls. Rett syndrome causes difficulties with social and language skills, as well as problems with activity and coordination. Most persons with Rett syndrome are never able to live independently and they may not live past middle age.
metabolic alkalosis
elevation of HCO3- usually caused by an excessive loss of metabolic acids
clear liquid diet
coffee, broth, tea
atelectasis
collapsed lung; incomplete expansion of alveoli
bronchitis occurs
the lower airways. Bronchitis is when there is inflammation in the large airways, the trachea and bronchi, which are part of the lower airways.
Physical carcinogens
ionizing radiation and ultraviolet light
aortic stenosis sound
swooshing
The Braden scale must be completed
once per shift
full liquid diet
peanut butter, ice cream, grape juice
A newborn infant should pass the first stool of meconium within
24 hrs after birth
respiratory acidosis
A drop in blood pH due to hypoventilation (too little breathing) and a resulting accumulation of Co2.
Aripiprazole
Antipsychotic, used for schizophrenia
If a gallop sound (S3) is heard
this indicates blood prematurely rushing into the ventricle. This is often related to volume overload as seen in heart failure, but could also be caused by pulmonary hypertension or coronary artery disease.
side effects of albuterol
tremor in extremities, restlessness, pounding HR
Valves of the heart
tricuspid valve, pulmonary semilunar valve, bicuspid or mitral valve, aortic semilunar valve
PVCs originate in the
ventricles of the heart
antipyretic
Medication used to reduce a fever
with Parkinson's, avoid foods high in
Vitamin B6
metabolic alkalosis causes
severe vomiting, excessive GI suctioning, diuretics, excessive NaHCO3
Gestational hypertension in the mother causes
A baby that will be small for gestational age. the fetus to be growth restricted due to inappropriate blood flow to the placenta and fetus.
Carbamazepine
Anticonvulsant
respiratory alkalosis
Arise in blood pH due to hyperventilation (excessive breathing) and a resulting decrease in CO2.
Which of the following medications lower blood pressure by reducing cardiac cell excitability?
Calcium channel blockers. When calcium enters the cell, it causes the cell to contract. Therefore, calcium channel blockers reduce cardiac cell excitability.
how to tell if patient is in fluid overload?
Chest X-Ray
foods high in vitamin B6
Meat, Poultry, Grains, Seeds, and Seafood
When should phytonadione be given?
Phytonadione is vitamin K. A newborn should be with mom for the first HOUR after delivery, and then given the vitamin K injection.
metabolic acidosis causes
Primary Cause: Addition of large amounts of fixed acids to body fluids; Contributing Causes: Lactic acidosis (circulatory failure), Ketoacidosis (diabetes, starvation), Phosphates and sulfates (Renal dz), Acid ingestion (salicylates), Secondary to respiratory alkalosis, Adrenal insufficiency
The S2 sounds of the heartbeat is
The Pulmonic valve closing
The S1 sounds of the heartbeat is
The Tricuspid valve closing
TURP syndrome
This complication occurs due to significant absorption of fluids used to irrigate the bladder. This causes significant volume overload and a resulting hyponatremia.
