The 1icensure examination which is administered by the Professional Regulation Commission, Board of Nursing is given to ______.

Correct Answer: D

Rationale: The correct answer is D because the licensure examination aims to assess if candidates meet the expected competency standards to practice nursing safely and effectively. This process ensures that only qualified individuals enter the profession, maintaining high standards of care. Choice A is incorrect because the exam goes beyond applying theory to include practical skills. Choice B is incorrect as protecting the public is the outcome of ensuring competency. Choice C is incorrect as the exam evaluates the full scope of nursing practice, not just its application.

Correct Answer: A

Rationale: The correct answer is A: Identify and count cases. In the initial stages of an outbreak investigation, it is crucial to identify and count cases to understand the scope and magnitude of the outbreak. By counting cases, Nurse Rona and her team can track the spread of the disease, identify common characteristics among those affected, and determine the extent of the outbreak. This step helps in guiding further investigation and control measures. Summary of other choices: B: Define and identify cases - While defining cases is important, it is not the initial step in outbreak investigation. C: Verify diagnosis - Verifying diagnosis is important but comes after identifying and counting cases. D: Prepare for field work - Field work is important in outbreak investigations, but it typically comes after the initial step of identifying and counting cases.

Correct Answer: C

Rationale: The correct answer is C: Primary prevention. In this scenario, the clinic focuses on preventing disease before it occurs through health education and immunization. Primary prevention aims to promote general health and prevent the onset of diseases. It targets the entire population to reduce the risk of disease occurrence. Incorrect Choices: A: Diagnosis and treatment - This choice involves identifying and treating existing health conditions, which is not the primary focus of a clinic designed for health education and immunization. B: Secondary prevention - This choice involves early detection and treatment of diseases to prevent complications, which is more focused on individuals who already have risk factors or symptoms, not on the general population. D: Tertiary prevention - This choice involves managing and treating complications of diseases to prevent further deterioration, which is not the primary goal of a clinic focused on health education and immunization.

Correct Answer: C

Rationale: The correct answer is C: Food and water. Typhoid fever is primarily transmitted through contaminated food and water by the bacterium Salmonella typhi. The bacteria are shed in the feces of infected individuals and can contaminate water sources or food prepared with contaminated water. This transmission route aligns with the typical epidemiology of typhoid fever outbreaks. Now, let's discuss why the other choices are incorrect: A: A vector - Typhoid fever is not transmitted by a vector such as mosquitoes or ticks. B: Blood and body fluids - Typhoid fever is not typically spread through blood or body fluids but rather through ingestion of contaminated food or water. D: Air - Typhoid fever is not an airborne disease and is not transmitted through the air.

Correct Answer: C

Rationale: The correct answer is C: Fifth month. Nurse Vera should explain that the fetal heart can typically be heard using a Doppler ultrasound device around the fifth month of pregnancy. This is because the baby's heart is developed enough to produce audible sounds by this time. Choices A, B, and D are incorrect because in the ninth month, the baby is ready for delivery, in the third month the heart is still developing, and in the first month the heart is just beginning to form and is not yet audible.
