Which adjunct is most effective in managing adults with sickle cell
disease?
A. Hydroxyurea (Droxin)
B. Heparin
C. Prednisone (Deltasone)
D. Rho(D) immunoglobulin (RhoGAM) - Correct Answer - A.
Hydroxyurea (Droxin)
Which finding is a sign of serotonin syndrome?
A. Bradycardia
B. Diaphoresis
C. Hypothermia
D. Lethargy - Correct Answer - B. Diaphoresis
Which receptor is located in the lungs?
A. Alpha
B. Beta1
pg. 1
,2|Page
C. Beta2
D. Dopaminergic - Correct Answer - C.
Beta2 receptors are located in the lungs and peripheral vessels. Alpha
receptors exist in vascular smooth muscle. Beta1 receptors are in the
myocardium. Dopaminergic receptors are found in renal, mesenteric,
cerebral, and coronary arteries.
A fracture of which bone does not always require anatomic alignment
for healing?
A. Wrist
B. Hip
C. Elbow
D. Clavicle - Correct Answer - D. Clavicle
Which dysrhythmia has premature P waves with a different
configuration than other P waves in the cardiac cycle?
A. Atrial flutter
B. Premature atrial complex
C. First-degree atrioventricular block
D. Second-degree atrioventricular block, type II - Correct Answer - B.
Premature atrial complexes are ectopic beats that are initiated by an
irritable atrial focus. P waves are present, but because the ectopic focus
originates the impulse outside the sinoatrial node, the premature P waves
have a different configuration. Atrial flutter causes no P waves, but it
causes flutter waves in a sawtoothed pattern. First-degree
atrioventricular block has a P wave for every QRS complex, but the PR

interval is consistently prolonged. Second-degree atrioventricular block,
type II, has one or more P waves for every QRS complex. In first-degree
atrioventricular block and second-degree atrioventricular block, type II,
the P wave configuration is consistent from P wave to P wave
Nutmeg toxicity is likely to cause which finding?
A. Hallucinations
B. Salivation
C. Rhabdomyolysis
D. Seizures - Correct Answer - A
In a patient with immune thrombocytopenic purpura, which finding
should you expect?
A. Tachypnea
B. Severe pain
C. Petechiae
D. Narrowing pulse pressure - Correct Answer - C. Petechiae
Which drug can cause a sense of omnipotence, excitement,
hyperalertness, hyperactivity, or hypersexuality?
A. Clonidine (Catapres)
B. Methaqualone (Quaalude)
C. Amphetamine (Adderall)
D. Amitriptyline (Elavil) - Correct Answer - C. Amphetamine (Adderall)

In most people, which area of the heart receives its blood supply from
the right coronary artery?
A. Posterior surface of the left ventricle
B. Anterior surface of the ventricular septum
C. Sinoatrial node
D. Left atrium - Correct Answer - C.
In about 60 percent of the population, the right coronary artery supplies
the sinoatrial node. The left anterior descending artery supplies the
anterior surface of the ventricular septum. The circumflex artery supplies
the posterior surface of the left ventricle and the left atrium.
Increased bowel sounds are a finding in which type of poisoning?
A. Barbiturate
B. Anticholinergic
C. Tricyclic antidepressant
D. Organophosphate - Correct Answer - D
When caring for a patient with superior vena cava syndrome, you should
be alert for which finding?
A. Hemarthrosis
B. Abdominal pain
C. Laryngeal swelling
D. Petechiae - Correct Answer - C. Laryngeal swelling
