Correct Answer: C

Rationale: The correct answer is C because the health care proxy can make treatment decisions for the client if the client is under anesthesia. This aligns with the concept of durable power of attorney for health care, where the proxy is authorized to make health care decisions when the client is unable to do so. Choices A, B, and D are incorrect. Choice A is incorrect because the proxy should make health care decisions only when the client is unable to do so. Choice B is incorrect as financial decisions are not typically within the scope of a health care proxy. Choice D is incorrect as managing legal issues is not the primary role of a health care proxy.

Correct Answer: B

Rationale: The correct answer is B because when a client reports feeling less anxious, it suggests that the treatment for a pulmonary embolism is effective. This is a good indicator of the client's overall well-being and response to treatment. Choices A, C, and D are incorrect because a chest x-ray revealing increased density in all fields, diminished breath sounds auscultated bilaterally, and ABG results showing specific values do not directly correlate with the effectiveness of treatment for a pulmonary embolism. While these assessments are important for monitoring the client's condition, the client's subjective report of feeling less anxious provides a more direct insight into the impact of the treatment.

Correct Answer: C

Rationale: The correct answer is C: Maternal hypoglycemia. Maternal hypoglycemia can lead to fetal bradycardia, which is indicated by a baseline FHR of 100/min. In this scenario, the sustained low baseline FHR suggests a possible link to maternal hypoglycemia. Maternal fever (Choice A) typically presents with tachycardia rather than bradycardia in the fetus. Fetal anemia (Choice B) usually causes fetal tachycardia as a compensatory mechanism to deliver more oxygen to tissues. Chorioamnionitis (Choice D) is associated with maternal fever and an elevated fetal heart rate, not a sustained low baseline FHR.

Correct Answer: B

Rationale: The correct answer is B: "You should restrict your fluid intake to 1 liter per day." Clients with heart failure should limit their fluid intake to prevent fluid overload, which can worsen their condition. Choice A is incorrect because 2 liters of water per day may be excessive for someone with heart failure. Choice C is incorrect as unlimited fluid intake is not suitable for individuals with heart failure. Choice D is also incorrect as 3 liters per day may be too much fluid for a client with heart failure.

Correct Answer: C

Rationale: The correct action to maintain a sterile field is to avoid reaching over it. This prevents contamination of the sterile environment by reducing the risk of unintentionally dropping microorganisms from non-sterile areas onto the sterile field. Opening sterile packages using the flap closest to your body first (choice A) is a good practice but not directly related to maintaining the sterile field. Donning sterile gloves before opening the sterile package (choice B) is crucial for maintaining sterility but not specific to maintaining the sterile field. Placing sterile items at least 2.5 cm (1 in) from the edge of the sterile field (choice D) is important to prevent accidental contamination, but it is not the primary action to maintain the sterile field.
