Adult Health Nursing Answer Key Questions
Question 1 of 5
A patient presents with scrotal pain, swelling, and erythema. On physical examination, there is a tender, fluctuant mass in the scrotum. What is the most likely diagnosis?
Correct Answer: B
Rationale: The most likely diagnosis in this scenario is epididymitis. Epididymitis is an inflammation of the epididymis, a coiled tube at the back of the testicle that stores and carries sperm. Common symptoms include scrotal pain, swelling, erythema (redness), and a tender, fluctuant mass in the scrotum due to an abscess. Risk factors for epididymitis include urinary tract infections, sexually transmitted infections (such as gonorrhea or chlamydia), and recent urological procedures. It is important to differentiate epididymitis from testicular torsion, which would present with sudden, severe testicular pain, absent cremasteric reflex, and a high-riding testicle. Testicular cancer typically presents as a painless mass or swelling in the scrotum, and hydrocele presents as painless scrotal swelling due to a collection of fluid
Question 2 of 5
A patient presents with watery diarrhea, abdominal cramps, and nausea after consuming contaminated water from a stream during a camping trip. Laboratory tests reveal oocysts in the stool sample. Which of the following parasites is most likely responsible for this infection?
Correct Answer: C
Rationale: Cryptosporidium parvum is a parasite commonly found in contaminated water sources such as streams or lakes. It causes an infection called cryptosporidiosis, which often presents with symptoms like watery diarrhea, abdominal cramps, and nausea. The oocysts of Cryptosporidium parvum can be identified in stool samples, making it the likely culprit in this scenario. Giardia lamblia, another common waterborne parasite, can also cause similar symptoms but is characterized by trophozoites rather than oocysts in stool samples. Entamoeba histolytica is associated with amoebic dysentery and does not typically present with watery diarrhea. Cyclospora cayetanensis is another parasite causing gastrointestinal symptoms but is not as commonly associated with contaminated water sources as Cryptosporidium parvum.
Question 3 of 5
A pregnant woman presents with sudden onset of severe abdominal pain and dark red vaginal bleeding at 28 weeks gestation. On examination, the uterus is tender, and the fundus feels firm. Which of the following conditions is the most likely cause of these symptoms?
Correct Answer: D
Rationale: The most likely cause of the sudden onset of severe abdominal pain and dark red vaginal bleeding with a tender, firm uterus at 28 weeks gestation is abruptio placentae. Abruptio placentae, also known as placental abruption, is the premature separation of the placenta from the uterine wall before delivery. This condition can be life-threatening to both the mother and the fetus, as it can lead to severe bleeding and compromise the oxygen and nutrients supply to the fetus. The presentation typically includes severe abdominal pain, dark red or maroon vaginal bleeding, uterine tenderness, and a firm uterus due to the blood accumulation behind the placenta. Prompt recognition and intervention are crucial to prevent adverse maternal and fetal outcomes.
Question 4 of 5
A pregnant woman presents with severe lower abdominal pain and vaginal bleeding. On examination, cervical motion tenderness and unilateral adnexal tenderness are noted, along with an adnexal mass on the affected side. Which of the following conditions is the most likely cause of these symptoms?
Correct Answer: A
Rationale: The clinical presentation of severe lower abdominal pain and vaginal bleeding in a pregnant woman, along with cervical motion tenderness, unilateral adnexal tenderness, and an adnexal mass on the affected side, is highly concerning for an ectopic pregnancy. Ectopic pregnancy occurs when a fertilized egg implants outside the uterus, most commonly in the fallopian tube. The presence of an adnexal mass and tenderness on one side is indicative of potential tubal involvement and can mimic symptoms of pelvic inflammatory disease. Prompt evaluation and management are crucial in ectopic pregnancy to prevent life-threatening complications associated with rupture of the fallopian tube.
Question 5 of 5
A woman in active labor is experiencing meconium-stained amniotic fluid. What is the nurse's priority action?
Correct Answer: B
Rationale: Meconium-stained amniotic fluid indicates that the fetus may have passed stool in utero, which can lead to potential respiratory problems once born due to meconium aspiration. The priority action for the nurse in this situation is to prepare for immediate delivery to expedite the removal of the fetus from the contaminated environment and provide necessary interventions such as suctioning of the airway to prevent aspiration of meconium. Prompt delivery is crucial to minimize the risk of complications related to meconium aspiration syndrome. Administering oxygen, inserting a urinary catheter, and notifying the neonatal resuscitation team can be important subsequent actions, but the immediate focus should be on delivering the baby.
