Correct Answer: D

Rationale: A pelvic ultrasound requires the client to have a full bladder because the bladder acts as a window through which pelvic organs, such as the uterus and ovaries, can be visualized more clearly. The full bladder pushes the intestines out of the way and provides a better acoustic pathway for the ultrasound waves. Without this, the pelvic organs might be obscured, and the images would be less accurate.

Correct Answer: B

Rationale: Before any invasive procedure, such as placing a catheter to deliver chemotherapy beads into a liver tumor, it is essential to ensure that informed consent has been obtained from the client. This is a legal and ethical requirement that ensures the client understands the procedure, its risks, benefits, and alternatives. Ensuring that the signed consent is on the chart is the most important action the nurse can take before the procedure, as the procedure cannot legally proceed without it.

Correct Answer: B

Rationale: Difficulty swallowing (dysphagia) following radiation therapy to the neck area is a significant concern because it can indicate serious complications such as esophageal stricture, inflammation, or damage to the surrounding tissues, including the esophagus. This can lead to malnutrition, dehydration, or aspiration, all of which require prompt intervention. Radiation therapy can cause irritation and scarring in the esophageal and throat tissues, which may progressively worsen if not treated. Therefore, dysphagia should be addressed immediately to prevent further complications.

Correct Answer: C

Rationale: Superior vena cava syndrome (SVCS) occurs when the superior vena cava, the large vein that carries blood from the upper body to the heart, becomes compressed or obstructed, often by a tumor or enlarged lymph nodes, typically in cancers like lung cancer or lymphoma. The obstruction leads to increased venous pressure and reduced blood flow, resulting in swelling and edema in areas drained by the superior vena cava. Periorbital edema (swelling around the eyes) is one of the earliest signs of SVCS. This occurs because the impaired venous return causes fluid to accumulate in the soft tissues of the face, especially around the eyes. As the condition progresses, facial swelling can worsen, and other symptoms develop.

Correct Answer: D

Rationale: In myelodysplastic syndrome (MDS), the bone marrow does not produce enough healthy blood cells, leading to conditions such as anemia. Administering erythropoietin is an effective intervention to manage anemia in MDS patients because it stimulates the production of red blood cells. This can help improve the patient's hemoglobin levels, reducing symptoms such as fatigue and weakness associated with anemia. Erythropoietin is commonly used in MDS to enhance red blood cell production and reduce the need for frequent blood transfusions.
