A 20-year-old man with respiratory depression is brought to the emergency
department by his parents. Opioid overdose is suspected, and an initial dose of
naloxone is administered at 10 p.m. The patient does not respond to this initial
dose. The team would expect to administer a second dose after how many minutes?
2 minutes
4 minutes
6 minutes
8 minutes
- answer-2 minutes
The dose of naloxone may be repeated after 2 to 3 minutes.
A 28-year-old pregnant patient who ‘resides ‘in ‘transitional ‘housing ‘presents ‘to ‘the
‘emergency ‘department ‘with ‘complaints ‘of ‘feeling ‘feverish ‘and ‘very ‘faint. ‘The
‘patient ‘tells ‘the ‘emergency ‘nurse ‘that ‘she ‘does ‘not ‘know ‘when ‘she ‘became
‘pregnant. ‘Upon ‘palpation, ‘the ‘fundus ‘is ‘not ‘at ‘or ‘above ‘the ‘umbilicus. ‘The
‘patient's ‘condition ‘quickly ‘deteriorates ‘and ‘she ‘goes ‘into ‘cardiac ‘arrest. ‘If
‘available ‘and ‘able ‘to ‘be ‘used ‘without ‘impeding ‘or ‘delaying ‘the ‘resuscitation
‘effort, ‘what ‘diagnostic ‘tool ‘could ‘be ‘used ‘to ‘guide ‘decision-making ‘in ‘the ‘care
‘of ‘this ‘patient?
Fetal ‘echocardiogram
‘Abdominal ‘radiograph
‘Point-of-care
‘ultrasound ‘Fetal
‘monitoring
- ‘answer-Point-of-care ‘ultrasound
Gestational ‘age ‘is ‘an ‘important ‘consideration ‘when ‘determining ‘the ‘approach ‘to
‘a ‘pregnant ‘patient ‘in ‘cardiac ‘arrest. ‘If ‘the ‘gestational ‘age ‘is ‘not ‘known ‘and
‘point-of- ‘care ‘ultrasound ‘is ‘available ‘and ‘able ‘to ‘be ‘performed ‘without ‘impeding
‘or ‘delaying ‘the ‘resuscitation ‘effort, ‘it ‘can ‘be ‘used ‘to ‘quickly ‘estimate ‘gestational
‘age ‘and ‘guide ‘decision-making.
,A ‘30-year-old ‘patient ‘has ‘been ‘brought ‘to ‘the ‘emergency ‘department ‘in ‘cardiac
‘arrest. ‘The ‘cardiac ‘monitor ‘shows ‘the ‘following ‘rhythm. ‘Interpretation ‘of ‘this
‘rhythm ‘would ‘suggest ‘which ‘of ‘the ‘following ‘as ‘a ‘possible ‘precipitating ‘factor?
Hemorrhage
‘Antibiotic ‘use
‘Electrocution
‘Cardiac ‘tamponade
- ‘answer-Electrocution
The ‘rhythm ‘is ‘ventricular ‘fibrillation. ‘Precipitating ‘causes ‘of ‘ventricular
‘fibrillation ‘include ‘electrocution, ‘myocardial ‘ischemia ‘or ‘infarction, ‘shock,
‘stimulant ‘overdose ‘and ‘ventricular ‘tachycardia.
A ‘35-year-old ‘female ‘patient's ‘ECG ‘is ‘consistent ‘with ‘STEMI. ‘The ‘ECG ‘reveals
‘a ‘new ‘ST-segment ‘elevation ‘at ‘the ‘J ‘point ‘in ‘leads ‘V2 ‘and ‘V3 ‘of ‘at ‘least ‘which
‘size?
0.10 ‘mV
0.15 ‘mV
0.2 ‘mV
0.25 ‘mV
- ‘answer-0.15 ‘mV
New ‘ST-segment ‘elevation ‘at ‘the ‘J ‘point ‘in ‘leads ‘V2 ‘and ‘V3 ‘of ‘at ‘least ‘0.15 ‘mV
‘(1.5 ‘mm) ‘in ‘women ‘40 ‘years ‘or ‘younger ‘is ‘considered ‘diagnostic ‘of ‘STEMI.
A ‘42-year-old ‘woman ‘presents ‘to ‘the ‘emergency ‘department ‘with ‘complaints ‘of
‘fatigue, ‘shortness ‘of ‘breath, ‘back ‘pain ‘and ‘nausea. ‘A ‘12-lead ‘ECG ‘is ‘obtained
‘and ‘shows ‘ST-segment ‘depression ‘in ‘leads ‘II, ‘III, ‘and ‘aVF ‘and ‘intermittent
‘runs ‘of ‘nonsustained ‘ventricular ‘tachycardia. ‘Cardiac ‘serum ‘markers ‘are
‘elevated. ‘These ‘findings ‘suggest ‘which ‘condition?
High-risk ‘non-ST-segment ‘elevation ‘ACS ‘(NSTE-
ACS) ‘Low-risk ‘non-ST-segment ‘elevation ‘ACS
‘(NSTE-ACS)
Intermittent-risk ‘non-ST-segment ‘elevation ‘ACS ‘(NSTE-
ACS) ‘ST-segment ‘elevation ‘myocardial ‘infarction ‘(STEMI)
- answer-High-risk ‘non-ST-segment ‘elevation ‘ACS ‘(NSTE-ACS)
The ‘12-lead ‘ECG ‘findings ‘of ‘ST-segment ‘depression ‘in ‘three ‘contiguous ‘leads
‘along ‘with ‘elevated ‘cardiac ‘serum ‘biomarkers ‘are ‘consistent ‘with ‘high-risk ‘non-
, ST-segment ‘elevation ‘ACS ‘(NSTE-ACS). ‘The ‘presence ‘of ‘intermittent ‘runs ‘of
‘ventricular ‘tachycardia ‘also ‘places ‘this ‘patient ‘at ‘high ‘risk. ‘In ‘ST-segment
‘elevation ‘myocardial ‘infarction ‘(STEMI), ‘cardiac ‘serum ‘markers ‘would ‘be
‘elevated, ‘but ‘this ‘patient's ‘ECG ‘findings ‘are ‘not ‘consistent ‘with ‘STEMI.
‘Patients ‘with ‘intermediate- ‘or ‘low-risk ‘NSTE-ACS ‘show ‘nondiagnostic ‘ST-
segment ‘or ‘T- ‘wave ‘changes ‘on ‘ECG, ‘or ‘no ‘changes ‘at ‘all.
A ‘member ‘of ‘the ‘resuscitation ‘team ‘is ‘preparing ‘to ‘administer ‘medications
‘intravenously ‘to ‘a ‘patient ‘in ‘cardiac ‘arrest. ‘The ‘team ‘member ‘should ‘follow
‘each ‘peripherally ‘administered ‘drug ‘dose ‘with ‘a ‘normal ‘saline ‘flush. ‘How ‘much
‘would ‘the ‘team ‘member ‘give?
5 ‘to ‘10 ‘mL
10 ‘to ‘20 ‘mL
20 ‘to ‘30 ‘mL
30 ‘to ‘40 ‘mL
- answer-10 ‘to ‘20 ‘mL
When ‘administering ‘medications ‘during ‘a ‘cardiac ‘arrest, ‘all ‘medications
‘administrated ‘through ‘the ‘IV ‘or ‘intraosseous ‘infusion ‘route ‘should ‘be ‘followed
‘by ‘a ‘10- ‘to ‘20-mL ‘normal ‘saline ‘flush.
A ‘member ‘of ‘the ‘resuscitation ‘team ‘is ‘preparing ‘to ‘defibrillate ‘a ‘patient ‘in
‘cardiac ‘arrest ‘using ‘a ‘biphasic ‘defibrillator. ‘The ‘team ‘member ‘would ‘set ‘the
‘energy ‘dose ‘according ‘to ‘the ‘manufacturer's ‘recommendations, ‘which ‘is ‘usually:
75 ‘to ‘100 ‘joules
120 ‘to ‘200 ‘joules
300 ‘joules
360 ‘joules
- answer-120 ‘to ‘200 ‘joules
When ‘using ‘a ‘biphasic ‘defibrillator, ‘the ‘energy ‘dose ‘should ‘be ‘set ‘at ‘120 ‘to ‘200
‘joules.
A ‘patient ‘arrives ‘at ‘the ‘emergency ‘department ‘complaining ‘of ‘shortness ‘of
‘breath. ‘The ‘patient ‘has ‘a ‘long ‘history ‘of ‘chronic ‘obstructive ‘pulmonary ‘disease.
Assessment ‘reveals ‘respiratory ‘failure. ‘Which ‘action ‘would ‘be ‘the ‘initial ‘priority
‘to ‘address ‘the ‘respiratory ‘failure?
