Which of the following statements BEST describes Public Health Nursing?

Correct Answer: D

Rationale: Public Health Nursing is a specialized field of nursing that focuses on promoting and protecting the health of populations and communities rather than individuals. One of the key principles of Public Health Nursing is the emphasis on health promotion and disease prevention strategies. This involves educating and empowering individuals, families, and communities to adopt healthy behaviors and lifestyles in order to prevent illness and improve overall well-being. Public Health Nurses work to address the root causes of health disparities and advocate for policies and programs that promote the health of entire populations. While providing care to sick individuals may be a component of Public Health Nursing, the primary focus is on preventing illness and promoting health at the community level.

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: D

Rationale: The most common symptom of scabies that the family would report to Nurse Emma is itchiness. Scabies is a contagious skin condition caused by the Sarcoptes scabiei mite, which burrows into the skin and lays eggs, leading to intense itching, especially at night. The itching is a result of the body's allergic reaction to the mites and their waste products. While rashes, scaling, and swelling can also occur with scabies, the hallmark and most bothersome symptom experienced by individuals with scabies is the intense itchiness, making it the most common symptom reported by affected individuals or their families during the history-taking process.

Correct Answer: C

Rationale: Nurse Minda should alert the unit staff to closely observe the fan because the occasional sparking may be a sign of an impending issue that could lead to a more serious problem. By closely monitoring the fan, the staff can ensure the safety of those in the unit and take necessary actions if the situation worsens. It is important to address potential safety hazards promptly to prevent any harm or damage.

Correct Answer: A

Rationale: The presentation described with sudden-onset, painless vision loss, a cherry-red spot at the macula, and attenuated retinal vessels is classic for central retinal artery occlusion (CRAO). CRAO occurs when the central retinal artery, which supplies blood to the inner retinal layers, becomes occluded. The cherry-red spot is due to the exposure of the underlying choroid, which still appears red as it is not affected by the blockage. Attenuated retinal vessels and a pale retina may also be seen due to ischemia. In contrast, central retinal vein occlusion (choice B) presents with sudden painless vision loss, retinal hemorrhages, dilated retinal veins, and cotton-wool spots. Retinal detachment (choice C) typically presents with flashes, floaters, and a curtain-like shadow across the vision. Acute angle-closure glaucoma (

Correct Answer: B

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: Placing the mother in a hands-and-knees position can help facilitate fetal rotation from occiput posterior to the desired occiput anterior position. This position utilizes gravity to assist in the repositioning of the baby, ultimately helping to alleviate back pain and promoting more efficient labor progress. It allows the baby's head to descend properly into the pelvis, potentially reducing the risk of a prolonged labor or the need for instrumental delivery. Additionally, being in this position can help the mother feel more comfortable and empowered during labor. Overall, assisting the mother into a hands-and-knees position is a non-invasive, low-risk intervention that can have a positive impact on both the mother and baby's well-being during labor.

Correct Answer: B

Rationale: In an educational program conducted by a nurse, it is crucial to involve the patient, their family, and significant others. This approach ensures holistic care by considering the patient's psychosocial environment, family dynamics, and support system. Including these individuals in the educational program fosters collaboration, strengthens the patient-nurse relationship, and equips family members with the knowledge and skills needed to provide optimal care at home. Furthermore, involving the patient's support system can enhance adherence to treatment plans and contribute to better health outcomes. Therefore, the presence and cooperation of the patient, family, and significant others are essential elements of a successful educational program led by a nurse.

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.
