(Latest Update 2025)
b.ureteral cystine calculus
c.testicular torsion
d.cystitis - Correct 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.

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 - Correct 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:

d.cuff leak - Correct Answer ✅D: Mechanical ventilation
requires diligent observation of the patient and ventilator by
