Correct Answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

Correct Answer: B

Rationale: The correct answer is Standard Precautions. Standard precautions are taken in all situations for all clients and involve all body secretions except sweat. They are designed to reduce the rate of transmission of microbes from one host to another or one source to another. Respiratory Isolation (Choice A) is used for diseases transmitted by airborne particles, not secretions and blood. Contact Isolation (Choice C) is for clients known or suspected to be infected with microorganisms that can be transmitted by direct or indirect contact. Droplet Isolation (Choice D) is used for diseases transmitted by large respiratory droplets expelled during coughing, sneezing, talking, or procedures.

Correct Answer: B

Rationale: The correct answer is B. Restraints are used as an emergency intervention when all other options to protect a client from imminent danger have been exhausted. Restraints should only be used as a last resort to ensure the safety of the client and others. Choices A, C, and D are incorrect because restraints are not used to maintain control, reinforce behavior, or are exclusively taken under direct physician supervision. It is crucial to remember that restraint use should always be based on careful assessment, documentation, and adherence to legal and ethical guidelines.

Correct Answer: B

Rationale: The correct statement regarding preparation for a lipoprotein fractionation test is that the client cannot eat for 12 hours before the test. It is important to note that the client can drink an unrestricted amount of water. Limiting fluid intake is not necessary for this test. There is no need for the client to ingest a lipid solution as part of the preparation. Therefore, the other choices are incorrect.

Correct Answer: D

Rationale: The correct answer is 'sunburn from lack of protection and overexposure.' First-degree burns primarily affect the outer layer of the skin and are commonly caused by overexposure to the sun without adequate protection, making it a significant concern for parents of small children. Choices A, B, and C describe other types of burns (scalding, contact with hot surfaces, and contact with flammable substances) that can cause more severe burns beyond the first-degree level. It is crucial for parents to be educated about sun safety measures to prevent sunburns in children.
