Correct Answer: C

Rationale: The correct answer is C: Swelling in the legs and shortness of breath. In heart failure, the heart is unable to pump effectively, leading to fluid accumulation in the body. Swelling in the legs (edema) is a classic sign of fluid overload as the fluid pools in the lower extremities. Shortness of breath occurs due to fluid accumulating in the lungs, causing difficulty in breathing. Weight loss and increased appetite (A) are not typical signs of fluid overload. Increased urine output and dehydration (B) are more indicative of fluid deficit. Nausea and vomiting (D) can occur in various conditions but are not specific to fluid overload in heart failure.

Correct Answer: C

Rationale: The correct answer is C: 12. At 18 months, a child should have 12 teeth, which include 8 incisors and 4 molars. This is because children typically start teething around 6 months, with the lower central incisors coming first. By 18 months, they should have all 8 incisors and usually the first set of molars. Options A, B, and D are incorrect because they do not align with the typical dental development timeline for children. Having only 6, 8, or 16 teeth at 18 months would indicate a delay or abnormality in dental growth.

Correct Answer: D

Rationale: The correct answer is D because palliative care aims to improve the quality of life for patients with serious illnesses like cancer. Severe pain and nausea (A) are common symptoms that palliative care helps manage. Uncontrolled symptoms despite treatment (B) indicate the need for specialized palliative care interventions. Psychosocial support needs (C) are also addressed in palliative care to address emotional and social aspects of the patient's well-being. Therefore, all of the above (D) are indicative of the need for palliative care as it focuses on holistic symptom management and support for the patient.

Correct Answer: D

Rationale: The correct answer is D: Encouraging early ambulation. Early ambulation helps prevent complications such as blood clots, pneumonia, and muscle weakness. It improves circulation, lung function, and overall recovery. Administering pain medication regularly (A) is important but not the top priority. Deep breathing exercises (B) are beneficial but not as crucial as early ambulation post-hip replacement. Monitoring for signs of infection (C) is essential but not the top priority for preventing complications in this case.

Correct Answer: B

Rationale: The correct answer is B: hamburgers. Clients with hypercholesterolemia should decrease their intake of foods high in saturated fats, like hamburgers. Saturated fats can raise LDL cholesterol levels. Broiled catfish (A) is a lean protein option, wheat bread (C) is a good source of fiber, and fresh apples (D) are a healthy fruit choice. Hamburgers (B) typically contain high levels of saturated fats from red meat and processed ingredients, making them a less ideal choice for individuals with high cholesterol.
