Correct Answer: B

Rationale: Ectopic pregnancy is a common complication of untreated gonorrhea or chlamydia infection in women. This occurs when a fertilized egg implants and grows outside the uterus, typically in one of the fallopian tubes. Both gonorrhea and chlamydia can lead to scarring of the fallopian tubes due to untreated inflammation and infection. This scarring may obstruct the fallopian tubes, making it difficult for the fertilized egg to travel to the uterus for implantation. As a result, the egg may implant and grow in the fallopian tube, leading to an ectopic pregnancy. Ectopic pregnancies are dangerous and can result in serious complications for the woman, including rupture of the fallopian tube, internal bleeding, and potentially life-threatening situations. It is crucial to seek prompt treatment for gonorrhea and chlamydia to prevent such severe outcomes.

Correct Answer: C

Rationale: Ciprofloxacin is an antibiotic commonly prescribed for the prevention of bacterial infections that can result from animal bites, such as dog bites. Dog bites are often contaminated with bacteria and can lead to infections, particularly from organisms such as Pasteurella multocida. Ciprofloxacin is effective against a broad range of bacteria, including those commonly found in animal bites, making it a suitable choice for infection prophylaxis in this scenario. Ibuprofen is a pain reliever and anti-inflammatory medication, tetanus toxoid is given to prevent tetanus infection, and meperidine is a narcotic analgesic used for pain relief, but none of these options specifically target bacterial prevention in the case of a dog bite.

Correct Answer: B

Rationale: Human chorionic gonadotropin (HCG) can be detected in the blood as early as 10 days after the last menstrual period. This hormone is produced by the placenta shortly after the embryo attaches to the uterine lining. Pregnancy tests detect HCG levels to determine pregnancy status, and the hormone can be detected earlier in the blood compared to urine tests. Detecting HCG in the blood at around 10 days post ovulation is often the earliest point when a blood test can confirm pregnancy.

Correct Answer: D

Rationale: When a woman in active labor demonstrates signs of cephalopelvic disproportion (CPD) with the fetal head failing to descend despite strong contractions, the nursing action that should be prioritized is to prepare for immediate instrumental delivery. CPD can lead to a prolonged and difficult labor, increasing the risks for both the mother and the fetus. In cases where the fetal head is not descending adequately and the mother's contractions are strong, instrumental delivery, like forceps or vacuum extraction, may be necessary to facilitate the safe delivery of the baby. It is important to act promptly to avoid potential complications associated with prolonged labor. Other actions, such as performing a pelvic exam, changing maternal positions, or administering oxytocin, may be considered but addressing the issue of CPD efficiently through instrumental delivery should take precedence in this scenario.

Correct Answer: C

Rationale: The most likely causative agent in this scenario is Borrelia burgdorferi, which is the bacterium responsible for causing Lyme disease. The classic presentation of Lyme disease includes fever, malaise, and a skin lesion resembling a "bull's eye" rash, known as erythema migrans. This rash typically appears at the site of a tick bite. If left untreated, Lyme disease can progress to involve multiple organ systems and lead to more severe complications. Plasmodium falciparum is the causative agent of malaria, which typically presents with symptoms such as fever, chills, and fatigue, but it does not cause a "bull's eye" rash. Trypanosoma cruzi is the parasite responsible for Chagas disease, which presents with symptoms such as fever, swelling at the site of entry (typically the bite wound), and enlarged lymph nodes, but it does not
