Updated by the Tigertest team. Based on the BCEN CEN Examination Content Outline effective July 2026. Original questions; 50 per test, weighted like the real exam. Not affiliated with BCEN.
1. A 14-year-old has sudden severe scrotal pain, nausea and a high-riding testis with no cremasteric reflex. What is the priority?
- A.Outpatient ultrasound
- B.Urgent surgical review
- C.Antibiotics and rest
- D.Ice and scrotal support
Answer: B. These findings suggest testicular torsion. The testis can be saved if blood flow is restored within about 6 hours, so it is a surgical emergency.
2. A patient has severe flank pain radiating to the groin, blood in the urine and cannot sit still. What is most likely?
- A.Bladder cancer
- B.Appendicitis
- C.Pyelonephritis
- D.Renal calculus
Answer: D. Colicky flank pain moving to the groin with hematuria is typical of a kidney stone. Pain control and hydration are the first steps.
3. A man has had a painful erection for 5 hours after injecting erectile medication. What is this?
- A.Ischemic priapism
- B.Urinary retention
- C.Normal side effect
- D.Peyronie's disease
Answer: A. A persistent painful erection over 4 hours is a urologic emergency, as trapped blood can damage the tissue. Aspiration and phenylephrine are used.
4. An older man cannot void and has lower abdominal pain. A bladder scan shows 900 mL. What is the priority?
- A.Give a diuretic
- B.Wait for spontaneous voiding
- C.Catheterize the bladder
- D.Encourage fluid intake
Answer: C. Acute urinary retention, often from an enlarged prostate, is relieved with a catheter. Fluids and diuretics would only add to the volume.
5. A woman of childbearing age has one-sided pelvic pain and vaginal spotting after a missed period. What must be ruled out first?
- A.Urinary infection
- B.Endometriosis
- C.Ectopic pregnancy
- D.Ovarian cyst
Answer: C. Any woman of childbearing age with pelvic pain needs a pregnancy test. A ruptured ectopic pregnancy can cause fatal bleeding.
6. A pregnant patient at 34 weeks has painless bright red vaginal bleeding. What should the nurse avoid?
- A.A digital vaginal exam
- B.Starting a large IV
- C.Left lateral positioning
- D.Fetal heart monitoring
Answer: A. Painless bleeding in late pregnancy suggests placenta previa. A digital exam can tear the placenta and cause heavy bleeding.
7. A pregnant patient in a car crash has dark vaginal bleeding and a rigid, tender uterus. What is most likely?
- A.Bladder injury
- B.Placenta previa
- C.Preterm labor only
- D.Abruptio placentae
Answer: D. Abruption, the placenta separating from the wall, causes painful bleeding and a firm uterus. Some blood can stay concealed behind the placenta.
8. A pregnant patient at 32 weeks has a blood pressure of 168/112, headache and visual changes. Which medication helps prevent seizures?
- A.Methylergonovine
- B.Magnesium sulfate
- C.Oxytocin
- D.Terbutaline
Answer: B. Severe preeclampsia is treated with magnesium sulfate to prevent eclamptic seizures. Deep tendon reflexes and breathing are watched for toxicity.
9. A patient on magnesium sulfate has absent knee reflexes and a respiratory rate of 10. Which antidote is given?
- A.Protamine sulfate
- B.Calcium gluconate
- C.Naloxone
- D.Flumazenil
Answer: B. Loss of reflexes and slowed breathing signal magnesium toxicity. IV calcium gluconate counters its effects.
10. A pregnant patient lying flat after trauma becomes hypotensive. What position change helps?
- A.Right side-lying
- B.Flat with legs raised
- C.Trendelenburg
- D.Left lateral tilt
Answer: D. After about 20 weeks the uterus can compress the vena cava when the patient lies flat. Tilting to the left restores venous return.
