Correct Answer: C

Rationale: The correct answer is C: Apply a sequential compression device. Applying a sequential compression device promotes venous return by assisting with blood circulation in the lower extremities, reducing the risk of blood clots. Encouraging deep breathing exercises can help with lung expansion but does not directly promote venous return. Maintaining the client in a supine position may not be ideal for promoting venous return if the client is unable to move. Massaging the client's legs may be contraindicated postoperatively due to the risk of dislodging a clot or causing trauma to the surgical site.

Correct Answer: B

Rationale: Myxedema is characterized by a decreased metabolic rate, leading to manifestations such as decreased temperature. Therefore, the correct assessment finding expected with myxedema is a decreased temperature. Choices A, C, and D are incorrect because myxedema typically presents with a decreased pulse rate, not an increased pulse rate, absence of fine tremors (which are more common in hyperthyroidism), and weight gain rather than weight loss.

Correct Answer: A

Rationale: The nurse plays a crucial role in preoperative patient care by providing education and ensuring NPO (nothing by mouth) status. This helps prepare the patient for surgery by ensuring they understand the procedure, what to expect, and also by following necessary preoperative fasting guidelines. While obtaining the patient's health history (choice C) is important for overall patient assessment, it is typically done during the preoperative assessment but does not specifically pertain to the nurse's role. Ensuring informed consent (choice B) is primarily the responsibility of the healthcare provider performing the procedure. Confirming the patient's surgical site (choice D) is usually the responsibility of the surgical team and is done immediately before the surgery to prevent errors.

Correct Answer: A

Rationale: Low birth weight increases a child's vulnerability to physical maltreatment due to additional care needs. Advanced maternal age (choice B) is not directly linked to an increased risk of physical maltreatment. Single parenthood (choice C) is not a characteristic that inherently increases the risk of physical maltreatment. Premature birth (choice D) is not listed as a characteristic that directly increases a child's risk of physical maltreatment.

Correct Answer: C

Rationale: The correct answer is C: Dependent edema. In right-sided heart failure, the heart is unable to effectively pump blood to the lungs for oxygenation, leading to fluid accumulation in the systemic circulation. This fluid backs up in the venous system, causing increased pressure in the veins of the body, resulting in dependent edema, usually starting in the lower extremities. Elevated blood glucose (choice A) is not directly related to right-sided heart failure. Decreased urine output (choice B) may occur in conditions like acute kidney injury but is not a specific finding of right-sided heart failure. Jaundice (choice D) is more commonly associated with liver dysfunction, not typically seen in right-sided heart failure.
