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
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
