Correct Answer: A

Rationale: Swelling and pain at the IV site can indicate extravasation, which is the leakage of a vesicant medication like doxorubicin hydrochloride into the surrounding tissues. It is crucial to stop the administration of the drug immediately upon suspicion of extravasation to minimize tissue damage and potential complications. By stopping the administration promptly, further harm can be prevented, and early interventions can be initiated to mitigate the effects of the extravasation. Notifications to the physician and appropriate actions, such as aspiration of any remaining drug, may follow after discontinuing the infusion.

Correct Answer: B

Rationale: The patient's frustration with chronic nasal congestion, anosmia, and inability to concentrate indicates difficulty coping with the long-term nature of her condition and the impact it has on her daily life. Additionally, her desire for relief suggests a need for environmental modifications to help manage her symptoms. This nursing diagnosis encompasses the patient's emotional response to her condition, as well as the potential need for changes in her surroundings to better support her health and well-being.

Correct Answer: A

Rationale: The most critical assessment parameter to include in the initial assessment of a patient with a brain tumor scheduled for surgery is the gag reflex. The gag reflex is a protective mechanism that prevents the entry of foreign objects into the airway and lungs. Patients undergoing brain tumor resection may be at risk for impaired gag reflex due to the effects of the tumor on cranial nerves or related structures. Identifying any impairment in the gag reflex is essential to prevent aspiration during and after the surgical procedure. Monitoring the gag reflex allows the healthcare team to take necessary precautions to protect the patient's airway and prevent complications. Therefore, assessing the gag reflex is crucial in the care of a patient with a brain tumor undergoing surgery.

Correct Answer: A

Rationale: Vaginal examination of the cervix may result in perforation of the placenta and subsequent hemorrhage in a patient admitted with suspected placenta previa. It is important to avoid any unnecessary manipulation of the cervix to prevent complications. Assessing cervical dilation and effacement should be avoided until placenta previa is ruled out to prevent harm to the patient.

Correct Answer: C

Rationale: Patients with Meniere's disease are often advised to limit their intake of salt as excess salt can worsen symptoms such as dizziness and vertigo. Shellfish tend to be high in sodium, so patients with Meniere's disease should be instructed to avoid or limit their consumption of shellfish to help manage their condition. It is important for the nurse to provide comprehensive diet education to the patient to help them minimize symptoms and improve their overall quality of life.
