What is the primary function of a public health nurse?

Correct Answer: C

Rationale: The primary function of a public health nurse is to promote and protect the health of populations. Public health nurses focus on preventing diseases, promoting healthy behaviors, and addressing health disparities within communities. Providing bedside care (choice A) is typically done by nurses in clinical settings, not public health nurses. Administering medications (choice B) is part of nursing practice but not the primary role of a public health nurse. Performing surgical procedures (choice D) is usually the responsibility of surgical nurses or healthcare providers specializing in surgery, not public health nurses.

Correct Answer: C

Rationale: The correct pathway of blood flow through the heart starts with blood entering the right atrium, moving to the right ventricle, then to the lungs for oxygenation, returning to the left atrium, and finally to the left ventricle before being pumped out to the body. Option A is incorrect as it starts with the ventricles instead of the atria. Option B is incorrect as it has the sequence of ventricles before atria reversed. Option D is incorrect as it has the atria and ventricles mixed up.

Correct Answer: A

Rationale: The correct nursing approach in the immediate postoperative period for a cleft lip repair in an infant is to remove protective arm devices one at a time for short periods with supervision. This approach helps prevent injury to the surgical site while ensuring the infant's comfort and safety. Choice B is incorrect as initiating oral feedings immediately after surgery may not be appropriate and could compromise the surgical site. Choice C is incorrect as introducing parents to the suture line cleansing protocol is important but not the immediate priority. Choice D is incorrect as positioning the infant on the back after feedings is not specific to the immediate postoperative period for a cleft lip repair.

Correct Answer: A

Rationale: The correct answer is A: Iloilo Mission Hospital School of Nursing. This nursing school holds the distinction of being the earliest in the Philippines. St. Paul's Hospital School of Nursing, University of Sto. Tomas College of Nursing, and Manila Central University are not the oldest nursing schools in the country, making them incorrect choices.

Correct Answer: C

Rationale: The correct sequence of steps in active management of the third stage of labor includes intramuscular injection of oxytocin to prevent postpartum hemorrhage, controlled cord traction with counter traction to the uterus to facilitate placental delivery, and uterine massage to aid in uterine contraction and prevent excessive bleeding. Choice A is incorrect because ergometrine administration is not routinely recommended in active management. Choice B is incorrect as intravenous oxytocin is not the preferred route of administration. Choice D is incorrect as the order of steps is not accurate.

Correct Answer: B

Rationale: The correct answer is B: conducting exercise classes at the community center. Regular physical activity plays a crucial role in preventing Type 2 diabetes by helping to maintain a healthy weight, improve insulin sensitivity, and regulate blood sugar levels. Distributing brochures (choice A) may raise awareness but might not lead to significant behavior change. Providing free glucose monitors (choice C) focuses on monitoring rather than prevention. Offering dietary counseling sessions (choice D) is important but focusing solely on diet may not address the comprehensive approach needed to prevent Type 2 diabetes.

Correct Answer: C

Rationale: The correct answer is C: Mental confusion. In this scenario, the client's high fever and pneumonia diagnosis indicate an infection. Infections, especially in older adults, can lead to mental confusion due to the body's systemic response to the infection. Flushed skin (choice A) is more commonly associated with fever but does not specifically relate to the client's condition. Bradycardia (choice B) and hypotension (choice D) are less likely findings in a client with pneumonia and a high fever; instead, tachycardia and increased blood pressure are more commonly seen in response to infection.

Correct Answer: B

Rationale: The correct answer is B: "Increase green leafy vegetable intake." This is the best advice because green leafy vegetables are rich in folic acid, which is essential for fetal development and helps prevent neural tube defects. Choice A is not specific enough and does not address the importance of folic acid. Choice C, drinking milk with each meal, does not provide the necessary folic acid intake. Choice D, eating fish weekly, is not as crucial for preconception diet changes as increasing folic acid intake.

Correct Answer: A

Rationale: The most important information for the nurse to obtain before initiating a community health program targeting teenage smoking is the incidence of smoking among the teenage population in the community. Understanding the prevalence of smoking will help in designing effective intervention strategies. Choice B about funding, while important, is secondary to understanding the scope of the issue. Choice C, the target objectives from Healthy People 2020, may provide guidance but are not as crucial as knowing the local prevalence. Choice D, satisfaction data from previous programs, does not provide essential information for planning a new program.
