Correct Answer: A

Rationale: The correct initial action upon discovering an electrical fire is to disconnect the electrical power if it can be done safely. This helps prevent the fire from spreading through the electrical system. Smothering the fire with a blanket is not recommended for electrical fires as it can fuel the fire. Saturating the source with water or other liquids is also not advised as it can lead to electric shock or spread the fire. Activating the fire alarm is important, but it should be done after disconnecting the power to prevent further escalation of the fire.

Correct Answer: D

Rationale: Breast implants can interfere with mammography by potentially preventing the detection of masses. The presence of implants can obscure a clear view of breast tissue, making it difficult to identify abnormalities such as masses that may indicate breast cancer. Choices A, B, and C are incorrect because discomfort, contraindications, and dislodgment are not primary reasons why breast implants interfere with mammography. The main concern is the impedance of detecting abnormalities accurately due to the implants.

Correct Answer: B

Rationale: The correct answer is B: Secondary prevention. Hearing screening for prematurely born infants falls under secondary prevention, which aims to identify and treat a condition in its early stages to prevent further complications. Primary prevention (choice A) focuses on preventing the disease from occurring, while tertiary prevention (choice C) involves managing complications and preventing disability. Choice D, disability prevention, is not a recognized category of prevention. In this context, the screening helps in early identification of hearing loss, allowing for timely intervention to prevent further impairment or complications, aligning with the principles of secondary prevention.

Correct Answer: C

Rationale: The correct goal of palliative care is to provide comprehensive care that addresses the physical, emotional, social, and spiritual needs of the dying client until the end of life. Therefore, the statement 'no interventions are needed because the client is near death' is incorrect as interventions are still essential to ensure comfort and quality of life. Choices A, B, and D are all aligned with the goals of palliative care, focusing on improving the quality of life, providing holistic care, and supporting both the family and the client.

Correct Answer: C

Rationale: A 5-year-old child can have up to 20 temporary (deciduous or baby) teeth. The first tooth usually erupts by age 6 months, and the last by age 30 months. All temporary teeth are usually shed between 6 and 13 years of age. Therefore, a 5-year-old child should have up to 20 temporary teeth. The correct answer is 'up to 20.' Choices A, B, and D are incorrect because the correct number of temporary teeth in a 5-year-old child's mouth is up to 20, not 10, 15, or 32.
