Correct Answer: D

Rationale: The appropriate nursing action in response to significantly high blood pressure readings like 172/104 mm Hg and 164/98 mm Hg is to confirm the readings by taking the blood pressure in the other arm. This can help rule out any error or issue specific to that arm. The nurse should then schedule a healthcare practitioner's appointment for as soon as possible to further assess the client's condition and determine the appropriate intervention. Choice A is incorrect because solely referring the client to a nutritionist for a low-sodium diet without further assessment or confirmation of the blood pressure readings is premature. Choice B is incorrect as the client is already seated, and calling paramedics for immediate transport to the hospital is not warranted based solely on the blood pressure readings provided. Choice C is incorrect as stress may not be the sole reason for the high blood pressure readings, and further assessment is required before referring the client to counseling services.

Correct Answer: B

Rationale: The correct answer is B: Health education. Health education is the process through which individuals acquire knowledge and skills to enhance their health and well-being. Health literacy (choice A) refers to the ability to understand and use health information, but it is not the same as the process of gaining knowledge and skills. Health promotion (choice C) involves advocating for health and implementing interventions to improve health outcomes, rather than the individual learning process. Health behavior (choice D) pertains to the actions individuals take regarding their health, not specifically the process of gaining knowledge and skills.

Correct Answer: B

Rationale: Restlessness and confusion are signs of hypoxia and hypercapnia in a client with COPD, indicating that the client's condition may be deteriorating rapidly. Immediate attention is necessary to prevent further complications. Nausea and vomiting (Choice A) may be related to various factors but do not directly indicate respiratory distress. Low-grade fever and cough (Choice C) are common in COPD and may not require immediate intervention. Irritating cough and liquefied sputum (Choice D) are typical symptoms of COPD exacerbation but do not signal an immediate need for attention as restlessness and confusion.

Correct Answer: A

Rationale: The correct answer is A: Primary prevention. Administering a booster dose of DTaP vaccine to an infant is an example of primary prevention. Primary prevention aims to prevent disease or injury before it occurs by preventing exposure to risk factors. Tertiary prevention focuses on reducing the impact of a disease or injury that has already occurred, while secondary prevention involves early detection and treatment to prevent the progression of disease. Choice B, tertiary prevention, is incorrect as it deals with managing the consequences of a disease rather than preventing it. Choice C, secondary prevention, is also incorrect as it focuses on early detection and treatment rather than vaccination to prevent the disease. Choice D, primary nursing, is unrelated to the level of prevention being implemented in this scenario.

Correct Answer: D

Rationale: A specific, measurable objective like reducing the number of underweight children by 10% is well-stated. This objective is clear, quantifiable, and time-bound, making it easier to track progress and evaluate the effectiveness of the plan. Choices A, B, and C are not as well-stated as they lack specificity, measurability, and a quantifiable target.
