Correct Answer: C

Rationale: The correct answer is C: 'Promoting health and preventing illness.' Primary health care aims to provide essential health services, promote health, prevent diseases, and manage common health problems. Choices A, B, and D are incorrect because primary health care focuses on a holistic approach to health that includes health promotion, disease prevention, treatment of common illnesses, and community participation, rather than specialized services, chronic disease treatment, or medical research.

Correct Answer: D

Rationale: The best strategy for the nurse to use when teaching insulin injection techniques to a newly diagnosed client with diabetes is to observe a return demonstration. This method ensures that the client can correctly perform the technique. Providing written pre and post tests (choice A) may assess knowledge but not application. Asking questions during practice (choice B) may help with understanding but not necessarily with the actual performance. Allowing another diabetic to assist (choice C) may provide peer support but does not guarantee correct technique demonstration.

Correct Answer: A

Rationale: The correct answer is A, maternal mortality. Maternal mortality specifically measures the risk of dying from pregnancy-related causes. Neonatal death rate, fetal death rate, and infant mortality rate focus on different populations and timeframes. Neonatal death rate refers to deaths within the first 28 days of life, fetal death rate measures stillbirths, and infant mortality rate includes deaths of infants under one year of age. Therefore, A is the most appropriate measure for assessing the risk of dying from causes related to pregnancy, childbirth, and puerperium.

Correct Answer: B

Rationale: In the management of acute respiratory infection in a child, it is essential to address various aspects of care. Providing safe remedies to relieve symptoms like sore throat and cough (Choice A) helps in managing discomfort. Advising the mother to monitor for signs of pneumonia (Choice C) is crucial for early detection and intervention if complications arise. Ensuring proper nutrition (Choice D) is important for the child's overall health and immune function during illness. Therefore, all the listed interventions are appropriate in managing acute respiratory infection, making Choice B the correct answer. Choices A, C, and D are incorrect on their own as they address only specific aspects of care and not the comprehensive management of acute respiratory infection.

Correct Answer: D

Rationale: Physical inactivity is a modifiable risk factor for chronic diseases because individuals have control over their level of physical activity. By increasing physical activity, the risk of chronic diseases can be reduced. Choices A, B, and C are not modifiable risk factors: Age is a non-modifiable factor, gender is a biological characteristic, and genetic predisposition is inherent and cannot be altered.
