Correct Answer: A

Rationale: The initial treatment goal for a patient like Mila is often focused on preventing infection. Infection prevention is a basic and essential step in patient care, especially for someone who may be at risk due to their medical condition or treatment plan. By preventing infection, healthcare providers can help ensure the patient's safety and promote successful outcomes for the overall treatment plan. Correcting hypoxia, metabolic acidosis, and increasing myocardial oxygen supply may be important goals as well, but preventing infection is usually prioritized as it can have serious consequences if not addressed promptly.

Correct Answer: A

Rationale: Colles' fracture is a type of distal radius fracture characterized by a break of the radius bone in the forearm close to the wrist. In a Colles' fracture, the distal fragment of the fractured radius bone gets displaced dorsally, meaning it shifts upwards towards the back of the hand, creating a characteristic "dinner fork" deformity when viewed from the side. This dorsal displacement results in a visible bump on the back of the wrist and a noticeable deformity when compared to the uninjured side.

Correct Answer: C

Rationale: The primary collaborative goal for the treatment of Ms. C should be to restore normal nutrition and weight. This is essential in addressing the potential health issues associated with anorexia nervosa, which is characterized by significantly low body weight and malnutrition. By focusing on restoring normal nutrition and weight, Ms. C can improve her physical health and overall well-being. Resolving possible dysfunctional family roles as an adolescent, increasing the desire to eat, and assisting her to increase feelings of control over eating are important aspects of treatment as well, but the most immediate goal should be to address the physical consequences of anorexia nervosa through restoring normal nutrition and weight.

Correct Answer: C

Rationale: Cryptosporidium parvum is a protozoan parasite that commonly causes waterborne illness characterized by watery diarrhea, abdominal cramps, and nausea. This parasite is often transmitted through contaminated water sources such as streams or lakes. Laboratory tests identifying oocysts in the stool sample are indicative of Cryptosporidium infection. Giardia lamblia can also cause similar symptoms, but the presence of oocysts points more towards Cryptosporidium in this case. Entamoeba histolytica causes amoebic dysentery with bloody diarrhea and is usually associated with fecal-oral transmission through contaminated food or water. Cyclospora cayetanensis typically causes prolonged watery diarrhea and is associated with the ingestion of contaminated food or water.

Correct Answer: C

Rationale: Excessive bleeding during a surgical procedure is a critical situation that requires immediate attention. The surgeon should be notified promptly so that appropriate interventions can be initiated to control the bleeding, such as applying pressure, administering hemostatic agents, or performing additional surgical measures. The surgeon is ultimately responsible for addressing the source of bleeding and ensuring the patient's safety during the procedure. It is important for the nurse to communicate effectively and collaborate with the surgical team to manage the situation efficiently and effectively.
