Correct Answer: C

Rationale: Naloxone, also known by the brand name Narcan, is used to reverse the effects of opioid overdose. Opioids can cause respiratory depression, sedation, and other signs of toxicity. Administering naloxone can quickly reverse these effects, restoring the patient's breathing and consciousness. This makes it the appropriate choice for reversing all signs of toxicity related to opioids. Digibind (Digoxin) is used to reverse toxicity from digoxin specifically. Atropine sulfate is used for bradycardia. Diazepam (Valium) is a benzodiazepine used for anxiety, seizures, and muscle relaxation, not for reversing toxicity.

Correct Answer: D

Rationale: Erosion is the dental condition characterized by the destruction of tooth structure due to exposure to acidic substances, such as gastric acid from conditions like gastroesophageal reflux disease (GERD) or acidic beverages like sodas and citrus fruits. This acidic attack softens and wears away the enamel, leading to the erosion of tooth structure. Unlike dental caries, which is caused by bacteria producing acid from sugars in the mouth, erosion is primarily a result of external acidic sources. Attrition refers to the wear of tooth structure from tooth-to-tooth contact, and abrasion refers to the wear of tooth structure due to forces like brushing too hard or using abrasive toothpaste.

Correct Answer: C

Rationale: Rapid capillary refill is a sign indicative of shock in a trauma patient. Shock is a life-threatening condition where the body's organs and tissues do not receive adequate blood flow and oxygen, leading to cellular damage and eventual organ failure. In a trauma patient, rapid capillary refill suggests poor perfusion, which is a common feature of shock. The capillary refill time is an important clinical assessment that measures the time it takes for color to return to the nail bed after pressure is applied. In cases of shock, the refill time is faster than normal, indicating a systemic circulatory disturbance. Other signs of shock may include tachycardia (increased heart rate), hypotension (not hypertension), and hypothermia (not hyperthermia).

Correct Answer: B

Rationale: As an epidemiology nurse, Nurse Rona's primary function and responsibility is to implement public health surveillance. Epidemiology nurses play a crucial role in monitoring and controlling the spread of diseases within communities. This involves conducting surveillance activities to identify patterns of disease occurrence, investigating outbreaks, collecting and analyzing data, and collaborating with various stakeholders to develop strategies for disease prevention and control. While providing nursing care to sick residents is important, the primary focus of an epidemiology nurse is on population-based health issues rather than individual patient care. Additionally, while Nurse Rona may assist epidemiologists in making reports and follow up cases and contacts, her main role is to implement public health surveillance to protect and promote the health of the community as a whole.

Correct Answer: C

Rationale: Uterine rupture is the most likely cause of these symptoms in a pregnant woman presenting with sudden onset of severe abdominal pain, vaginal bleeding, rigidity of the abdomen, and palpable fetal parts abdominally. Uterine rupture is a rare but serious complication of pregnancy, typically occurring during labor in women with a previous cesarean delivery or other uterine scars. The sudden onset of severe abdominal pain can be associated with vaginal bleeding due to the tearing of the uterine wall, causing fetal parts to be palpable abdominally. This is a life-threatening emergency that requires immediate medical intervention. Ectopic pregnancy, pelvic inflammatory disease, and ovarian torsion may present with abdominal pain and vaginal bleeding but would not typically present with palpable fetal parts abdominally in a pregnant woman.
