Question 1 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: The correct answer is C: Cryptosporidium parvum. This parasite is the most likely cause of the infection due to its presentation with watery diarrhea, abdominal cramps, and nausea after consuming contaminated water. Laboratory tests revealing oocysts in the stool sample further support this diagnosis as Cryptosporidium parvum is known to produce oocysts in the stool. Giardia lamblia (choice A) presents with similar symptoms but does not typically produce oocysts. Entamoeba histolytica (choice B) is more associated with bloody diarrhea and liver abscesses. Cyclospora cayetanensis (choice D) is also associated with watery diarrhea but is less common in this scenario. Thus, based on the symptoms and laboratory findings, Cryptosporidium parvum is the most likely culprit.
Question 2 of 5
A pregnant woman presents with severe abdominal pain and passage of tissue at 12 weeks gestation. On examination, the cervix is partially dilated, and products of conception are protruding through the cervical os. Which of the following conditions is the most likely cause of these symptoms?
Correct Answer: B
Rationale: In this scenario, the pregnant woman is presenting with severe abdominal pain, passage of tissue, and cervical dilation with products of conception protruding through the cervical os at 12 weeks gestation. These are classic signs and symptoms of an incomplete abortion. Incomplete abortion occurs when not all of the products of conception are expelled from the uterus. It can present with vaginal bleeding, abdominal pain, cervical dilation, and passage of tissue. The management of incomplete abortion may involve expectant, medical, or surgical options depending on the clinical context and the patient's condition.
Question 3 of 5
A pregnant woman presents with fever, chills, and abdominal pain localized to the right upper quadrant. On examination, she has tenderness in the right upper abdomen and a positive Murphy's sign. Which of the following conditions is the most likely cause of these symptoms?
Correct Answer: C
Rationale: The scenario described in the question is consistent with acute cholecystitis, which is inflammation of the gallbladder usually caused by an impacted gallstone in the cystic duct. The key clinical features of acute cholecystitis include fever, chills, right upper quadrant abdominal pain (which can be localized to the right upper quadrant), tenderness in the right upper abdomen, and a positive Murphy's sign (pain and inspiratory arrest upon palpation of the right upper quadrant). This condition is more common in pregnant women due to hormonal changes that can lead to gallstone formation and subsequent inflammation of the gallbladder. Ectopic pregnancy, pelvic inflammatory disease, and ovarian torsion typically present with different clinical features compared to those described in acute cholecystitis.
Question 4 of 5
A woman in active labor is receiving an epidural analgesic for pain relief. What assessment findings indicate a potential complication of epidural analgesia?
Correct Answer: A
Rationale: One potential complication of epidural analgesia in labor is maternal hypotension. The epidural analgesic can cause vasodilation, leading to a decrease in blood pressure. Maternal hypotension can result in decreased placental perfusion, which may jeopardize fetal well-being. It is important for healthcare providers to monitor the maternal blood pressure closely and intervene promptly if hypotension occurs by providing IV fluids or administering medication to raise blood pressure. Uterine hyperstimulation, fetal tachycardia, and respiratory depression are not typically associated with epidural analgesia as complications.
Question 5 of 5
A woman in active labor is experiencing precipitous labor with rapid cervical dilation and descent of the fetal presenting part. What maternal complication should the nurse anticipate?
Correct Answer: A
Rationale: Precipitous labor is characterized by rapid cervical dilation and descent of the fetal presenting part, leading to a shortened labor duration of less than 3 hours. This rapid progression can increase the risk of maternal complications, such as postpartum hemorrhage. Postpartum hemorrhage is defined as excessive bleeding of more than 500 ml after vaginal delivery or more than 1000 ml after cesarean delivery. The rapid delivery in precipitous labor can result in inadequate uterine contractions after delivery, leading to poor uterine tone and potential postpartum hemorrhage due to uterine atony. Therefore, the nurse should anticipate postpartum hemorrhage as a potential maternal complication in a woman experiencing precipitous labor.
