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 - ✔️✔️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 - ✔️✔️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
