The nurse is caring for a client with congestive heart failure. On assessment, the nurse notes that the client is dyspneic and that crackles are audible on auscultation. The nurse suspects excess fluid volume. What additional signs would the nurse expect to note in this client if excess fluid volume is present?

Correct Answer: C

Rationale: An increase in blood pressure is a common sign of fluid volume excess in clients with congestive heart failure due to the increased amount of fluid in the vascular system. Weight loss (Choice A) is not typically associated with fluid volume excess. Flat neck and hand veins (Choice B) are signs of fluid volume deficit, not excess. A decreased central venous pressure (CVP) (Choice D) is not expected in a client with fluid volume excess.

Correct Answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

Correct Answer: A

Rationale: The correct answer is A: Autonomy. Autonomy is the ethical principle that respects an individual's right to make their own decisions, including the right to refuse treatment. This principle acknowledges the patient's self-governance and independence in making choices about their own healthcare. Choice B, Nonmaleficence, refers to the ethical principle of doing no harm and ensuring patient safety. Choice C, Beneficence, involves promoting the patient's well-being and acting in their best interest. Choice D, Justice, pertains to fairness and equitable distribution of healthcare resources.

Correct Answer: D

Rationale: The correct answer is D. Ethical principles can influence the creation of laws but are not equivalent to laws themselves. Laws are established by governing bodies to provide a framework for society, whereas ethical principles guide individuals' moral conduct. Choice A is incorrect because governments enforce laws, not ethics. Choice B is incorrect as laws set legal standards rather than ethical ones. Choice C is incorrect because ethics are principles that guide behavior but are not necessarily highly specific.
