Which dysrhythmia would be identified on an ECG/EKG six-second strip by a heart rate of 76
and a PR interval of 0.24?
a.sinus tachycardia
b.first-degree atrioventricular block
c.sinus bradycardia
d.junctional escape rhythm - ANSWER B: First-degree atrioventricular block is
diagnosed partially by an EKG showing a PR interval of greater than 0.20 seconds.
Which blood test may indicate infection or inflammation and would need to be used as part
of the clinical picture with diagnosing and treating abdominal pain?
a.white blood cell (WBC) count of 5.0
b.hematocrit (HCT) of 45
c.WBC count of 28.0
d.blood sugar (BS) of 74 - ANSWER C: An elevated WBC count would be indicative of
infection or inflammation. The WBC count of 5.0 is normal. The HCT and BS levels listed
would also be considered within normal limits.
A 30-year-old man comes to the emergency department with the acute onset of left flank
pain radiating to the groin. Microscopic hematuria is present on urinalysis. What is the most
likely diagnosis?
a.ureteral calcium oxalate calculus
b.ureteral cystine calculus
c.testicular torsion
1
, d.cystitis - ANSWER A: Ureteral calculi are a quite common cause of acute emergency
evaluation, usually causing flank pain with radiation to the back and/or groin. About 75% of
these are calcium oxalate or phosphate; less common are struvite, uric acid, or cystine
calculi. While KUB or ultrasound may show the stone, helical CT is now the preferred
diagnostic method. Additional workup includes CBC, chemistry panel, urinalysis, and
straining of urine to catch a passed stone for chemical analysis. Nursing attention should be
directed to intravenous hydration with input and output recording and narcotic or narcotic
plus NSAID (e.g., ketorolac) administration for pain. Some patients may be discharged with
analgesics and instructions for hydration and calculus capture. Testicular torsion is most
common in adolescents and usually presents with testicular and groin pain with abdominal
radiation; increasing pain by lifting the scrotum to the level of the pubic symphysis causes
exacerbation of the pain (Prehn sign). Cystitis may be infectious or drug-induced, but cystitis
usually causes dysuria and pyuria and shows positive urine cultures.
Which of the following is NOT appropriate for screening for domestic violence by the
emergency department nurse?
a.asking if the person has been hit, kicked, or otherwise hurt by someone in the past year; if
so, by whom
b.asking, "Do you feel safe in your present relationship?"
c.avoid asking about intimate person violence if the patient is in the emergency department
for a medical ailment, not trauma
d.asking if there is a partner from a previous relationship that makes the individual feel
unsafe - ANSWER C: Domestic violence, nearly always perpetrated against women, is a
major problem confronted by the emergency nurse. Screening for possible cases should
include answers A, B and D. Interestingly, victims of intimate partner violence often present
with a medical ailment, not trauma. These include back, abdominal, or pelvic pain,
headaches, urinary infections, sexually transmitted disease, or symptoms consistent with
posttraumatic stress disorder (PTSD). Sometimes evidence of old trauma such as healing
fractures or cosmetically concealed bruises may point toward the presence of domestic
violence. Many victims will deny it but sometimes compassionate questioning in a private
setting will elicit a positive response. The nurse may then offer advice, refer to a social
agency or shelter, or ask for a consultation by the hospital social worker.
A patient is intubated and on mechanical ventilation. The ventilator alarm rings and the
airway pressure is found to be elevated. Possible causes include the following EXCEPT:
a.endotracheal tube obstruction with sputum
