Rationale: The positive practice environment (PPE) in a health care setting typically includes components such as waste management, infection control, and peer review. However, electrical wires are not a standard component of the PPE in a work setting. Electrical safety is important in a healthcare facility, but it is usually addressed in a separate set of guidelines and protocols focusing specifically on electrical safety and maintenance. Therefore, among the given options, electrical wires are not considered a component of the positive practice environment in the work setting.

Correct Answer: A

Rationale: In cases of poisoning, the main goals are to inactivate the poison to prevent further harm, administer the specific antidote if available to counteract the effects of the poison, and support vital organ functions to help the patient recover. Inducing the patient to vomit (III) is not always recommended as it can potentially cause more harm, especially if the ingested substance is corrosive. Therefore, the most appropriate goals in poisoning are to inactivate the poison, administer the specific antidote, and support vital organ functions.

Correct Answer: C

Rationale: Cryptosporidium parvum is a protozoan parasite often found in contaminated water sources. This parasite is known to cause watery diarrhea, abdominal cramps, and nausea in infected individuals. The presence of oocysts in the stool sample is characteristic of Cryptosporidium infection. Other parasitic infections may present with similar symptoms, but in this case, the most likely culprit based on the exposure history and laboratory findings is Cryptosporidium parvum.

Correct Answer: C

Rationale: The health care team will try the oral route first for Ms. C for delivering nutrition and fluid because it is the most natural and least invasive method. If the patient is able to tolerate oral intake and has adequate oral intake, it is typically the preferred route. Only if she is unable to meet her nutritional needs orally or has difficulty swallowing, then alternative routes such as nasogastric tube, gastrostomy tube, or intravenous routes may be considered. It's important to promote oral intake whenever possible to maintain the patient's quality of life and prevent complications associated with more invasive methods.

Correct Answer: B

Rationale: Mood swings are recognized as a typical part of a normal pregnancy due to the hormonal changes that occur. Pregnant individuals may experience a wide range of emotions, from joy and elation to frustration and irritability. These fluctuations in mood are considered normal and not necessarily indicative of a more serious issue. It is essential for pregnant women to receive support and understanding during this time as they navigate the emotional ups and downs of pregnancy. Feelings being easily hurt by remarks (A) and narcissism (D) are not typically accepted as part of a normal pregnancy and may require further attention or support. While finding a situation amusing or charming (C) can be a positive experience, it is not specifically indicative of a normal emotional reaction during pregnancy.
