A patient with STEMI is experiencing chest pain that is refractory to sublingual
nitroglycerin. Intravenous nitroglycerin is prescribed. When administering this
medication, it would be titrated to maintain which systolic blood pressure?
Select the correct answer to this question.
60 mmHg
70 mmHg
80 mmHg
90 mmHg - ANSWER> 90 mmHg
In patients with STEMI, IV nitroglycerin may be used when chest pain or
discomfort is recurrent or refractory to nitroglycerin administered sublingually or
by spray. The IV nitroglycerin should be titrated to maintain a systolic blood
pressure of 90 mmHg or more.
Cardiac monitoring indicates that a patient has a ventricular tachyarrhythmia. The
patient has a pulse and is not showing any signs of hemodynamic compromise. A
12-lead ECG reveals an irregular rhythm with QRS complexes greater than 0.12
second in duration. Which action would be appropriate at this time?
Select the correct answer to this question.
Synchronized cardioversion
Atropine
1|Pag e
,Defibrillation
Consider an antiarrhythmic infusion and expert consultation - ANSWER>
Consider an antiarrhythmic infusion and expert consultation
A patient experiencing STEMI comes to the emergency department of a large
medical center at 9:30 p.m. The patient states that the symptoms started about 8
p.m. After confirming the diagnosis and initiating care, the healthcare team
schedules the patient for percutaneous coronary intervention (PCI). The facility is
capable of administering PCI. To achieve the best outcomes, therapy should be
administered to this patient by which time?
Select the correct answer to this question.
11:00 p.m.
12:00 a.m.
1:00 a.m.
1:30 a.m. - ANSWER> 11:00 p.m.
Reperfusion therapy should be administered within 1 hour, 30 minutes of the
patient's first medical contact if the patient does not need to be transferred to
another facility. The patient arrived at 9:30 p.m., so the latest the therapy should be
administered would be 11 p.m.
Assessment of a patient reveals an ETCO2 level of 55 mmHg and an arterial
oxygen saturation (SaO2) level of 88%. The provider would interpret these
findings as indicative of which condition?
Select the correct answer to this question.
Respiratory distress
Cardiac arrest

, Respiratory failure
Respiratory arrest - ANSWER> Respiratory failure
A patient in the telemetry unit is receiving continuous cardiac monitoring. The
patient has a history of myocardial infarction. The patient's ECG rhythm strip is
shown in the following figure. The provider interprets this strip as indicating which
arrhythmia?
Second-degree AV block
First-degree atrioventricular (AV) block
Sinus tachycardia
Third-degree AV block - ANSWER> Third-degree AV block
A patient is being treated in the emergency department and is determined to have
NSTE-ACS. Invasive management is planned based on which finding?
Select the correct answer to this question.
Atrial tachycardia
Ventricular tachycardia
Atrial fibrillation
Ventricular fibrillation - ANSWER> Ventricular tachycardia
An early invasive strategy should be considered for patients with high-risk NSTE-
ACS, which would be indicated by ventricular tachycardia.
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?
Delivery of supplemental oxygen via nasal cannula
