Correct Answer: B

Rationale: The correct answer is B: Uterine infection. The patient's symptoms of crampy abdominal pain, scant serosanguineous vaginal drainage with odor, negative pregnancy test, and vital signs indicating fever, low blood pressure, and irregular pulse suggest an infection. The history of recent miscarriage raises suspicion for retained products of conception leading to infection. Ectopic pregnancy (choice A) would present with different symptoms such as abdominal pain, vaginal bleeding, and positive pregnancy test. Gestational trophoblastic disease (choice C) typically presents with abnormal vaginal bleeding and high levels of hCG. Endometriosis (choice D) is a chronic condition and not related to the acute symptoms described. In summary, the clinical presentation aligns with uterine infection given the patient's history, symptoms, and vital signs.

Correct Answer: D

Rationale: The correct answer is D: The patient has been infected with HIV. Antibodies to the AIDS virus in the blood indicate a past or current infection with HIV. This is because the body produces antibodies in response to the presence of the virus. A: The patient is immune to HIV is incorrect because antibodies indicate exposure, not immunity. B: The patient's immune system is intact is incorrect because the presence of antibodies does not necessarily reflect the overall functionality of the immune system. C: The patient has AIDS-related complications is incorrect because the presence of antibodies does not directly indicate the presence of AIDS-related complications.

Correct Answer: A

Rationale: The correct answer is A: Have you ever experienced claustrophobia or feelings of anxiety while in enclosed spaces? This question is important because electronystagmography involves the patient being placed in a confined space with sensors attached to monitor eye movements. Claustrophobia or anxiety can significantly impact the patient's ability to tolerate the test, affecting its accuracy. Choice B: Do you currently take any tranquilizers or stimulants on a regular basis? While relevant in some cases, it is not as crucial as ensuring the patient can tolerate the test environment. Choice C: Do you have a history of falls or problems with loss of balance? While relevant to Mnire's disease, it is not directly related to the preparation for electronystagmography. Choice D: Do you have a history of either high or low blood pressure? While monitoring blood pressure is important for some procedures, it is not a primary concern for electronystagmography.

Correct Answer: C

Rationale: The correct answer is C: Hydrocele. A hydrocele is the collection of fluid in the tunica vaginalis of the testes. This condition is common in newborns and can also occur in adolescents. Cryptorchidism (A) is the absence of one or both testes from the scrotum. Orchitis (B) is inflammation of the testicles. Prostatism (D) is a non-specific term related to prostate issues, not relevant to the given scenario. Therefore, the correct diagnosis for an adolescent with fluid collection in the tunica vaginalis of his testes is hydrocele.

Correct Answer: A

Rationale: The correct answer is A: Abdominal palpation. Palpating the abdomen can potentially cause rupture of the liver in patients with HELLP syndrome due to increased risk of liver hematoma. This can lead to severe bleeding and compromise the patient's condition. Checking deep tendon reflexes (C), auscultation of the heart and lungs (D), and venous sample of blood (B) are safe assessments that do not pose a risk of exacerbating the patient's condition. It is crucial to prioritize patient safety and avoid interventions that can harm the patient, making avoiding abdominal palpation the correct choice in caring for a patient with HELLP syndrome.
