Correct Answer: A

Rationale: Informed consent is a person's agreement to allow something, such as a treatment, to be performed. A consent form is required even if the problem is a sexually transmitted infection. If the client is a minor, the minor may sign the informed consent form in specific situations, including seeking treatment for a sexually transmitted infection. In this case, the 17-year-old client is seeking examination and treatment for a sexually transmitted infection, so she will need to sign the informed consent form. Contacting her parents for permission is not required in this situation. Choice C is incorrect because a consent form is necessary regardless of the medical issue. Choice D is incorrect because the individual's age is not the determining factor; rather, it is the nature of the medical service being sought that dictates the need for informed consent.

Correct Answer: B

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

Correct Answer: A

Rationale: The correct answer is hepatitis A. Hepatitis A does not produce a carrier state after its acute phase. It is transmitted via contaminated water or food through the oral-fecal route and is not blood-borne. Hepatitis B, choice B, can lead to a carrier state where the person remains infectious despite being asymptomatic. Hepatitis C, choice C, can also result in a chronic carrier state. Hepatitis D, choice D, is an incomplete virus that requires hepatitis B to replicate; it does not lead to a carrier state on its own.

Correct Answer: C

Rationale: The correct intervention when a client is restrained is to assess the restraint every 30 minutes. This ensures the safety and well-being of the client by checking for proper fit, circulation, and signs of distress. Removing restraints and providing skin care every hour may not be necessary and could increase the risk of skin breakdown. Documenting the skin condition every 3 hours is important but not the immediate intervention needed when a client is restrained. Tying the restraint to the side rails is unsafe and can cause harm to the client, as restraints should be secured to the bed frame or an immovable part of the bed.

Correct Answer: D

Rationale: The correct answer is 'To be aware of the role of the licensed nurse.' Nurse practice acts outline the scope of practice for nurses, defining what constitutes nursing practice and the role of licensed nurses. Choice A is incorrect because hospital and long-term care facility policies are institution-specific and not typically covered in the nurse practice act. Choice B is incorrect as the scope of practice for nurses is a part of the nurse practice act, but it's not the sole purpose for a nurse to refer to it. Choice C is incorrect as health care policies in a state are governed by other legislative acts, not the nurse practice act.
