1. Which of the following measures the frequency of new cases of the phenomenon during a given period of time?

Correct answer: D

Rationale: The correct answer is D, incidence rate. Incidence rate measures the frequency of new cases of a phenomenon, providing important information about the risk of developing the condition. Prevalence rate (choice A) reflects both old and new cases, proportionate mortality rate (choice B) is the proportion of deaths due to a specific cause, and case fatality rate (choice C) measures the proportion of deaths among confirmed cases, not just new cases.

2. The client with Raynaud's phenomenon would benefit most by which teaching intervention?

Correct answer: A

Rationale: The correct answer is A: Stop smoking. Smoking causes vasoconstriction, worsening the symptoms of Raynaud's phenomenon. Quitting smoking is crucial in managing this condition effectively. Choices B, C, and D are not as directly related to the pathophysiology of Raynaud's phenomenon. While keeping feet dry and reducing stress can be beneficial for overall health, they are not as directly linked to managing Raynaud's phenomenon as smoking cessation.

3. The Healthy People project is designed to:

Correct answer: C

Rationale: The Healthy People project is designed to follow health indicators such as activity, substance use, mental health, and environmental issues to improve public health outcomes. Choice A is incorrect because the project focuses on public health indicators rather than insurance liabilities. Choice B is incorrect as the project actually acknowledges the significant impact of social factors on health. Choice D is incorrect because one of the main goals of the Healthy People project is to identify and address disparities in access to healthcare, not to demonstrate that access is adequate for all populations.

4. A home health nurse knows that a 70-year-old male client who is convalescing at home following a hip replacement is at risk for developing decubitus ulcers. Which physical characteristic of aging contributes to such a risk?

Correct answer: C

Rationale: Thinning of the skin with loss of elasticity is the physical characteristic of aging that contributes to an increased risk of developing decubitus ulcers. As individuals age, the skin becomes thinner and loses its elasticity, making it more susceptible to damage from pressure, leading to the formation of pressure ulcers. Choices A, B, and D are incorrect as they do not directly contribute to the development of decubitus ulcers in this context.

5. Manny Pacquiao, a Filipino and world boxing champion, used to advertise a muscle pain-relieving drug popularly known in the Philippine market. What can be an equally effective medicinal alternative, especially in far-flung communities and provinces, to relieve muscles and joint pains and prove to be non-costly?

Correct answer: D

Rationale: Yerba Buena is a suitable alternative for muscle and joint pain relief, particularly in remote areas due to its cost-effectiveness and proven efficacy. Sambong is more commonly used for urinary tract problems, Lagundi is known for respiratory conditions, and Akapulko is primarily used for skin diseases, making them less effective alternatives for muscle and joint pain relief.
