Correct Answer: D

Rationale: The cough of a patient with lung cancer typically starts off as dry and persistent. This is because lung cancer can irritate the airways, leading to a persistent dry cough as an early symptom. As the cancer progresses, the cough may become more productive with blood-tinged or dark yellow sputum. However, in the early stages, the cough is often dry and persistent, which can be a warning sign for healthcare providers to further investigate potential underlying issues such as lung cancer.

Correct Answer: B

Rationale: In the situation of an obstetric emergency requiring immediate delivery, the priority nursing action is to prepare the delivery room for the birth. This involves ensuring that all necessary supplies and equipment are readily available, the bed is adjusted to the appropriate position, and the healthcare team is prepared to assist with the birth. By expeditiously preparing the delivery room, the healthcare team can facilitate a safe and timely delivery for both the mother and the baby. Notifications to the healthcare provider, administering intravenous fluids, and continuous fetal monitoring can be done simultaneously but preparing the delivery room takes precedence to ensure a prompt response to the emergent situation.

Correct Answer: A

Rationale: Multiple myeloma is a type of cancer that develops in plasma cells, which are a type of white blood cells involved in the body's immune response. As a result, multiple myeloma primarily affects the hematologic system, which includes the blood and blood-forming tissues. This cancer typically arises in the bone marrow and can lead to an overproduction of abnormal plasma cells, which can crowd out healthy blood cells. Symptoms of multiple myeloma can include anemia, bone pain, recurrent infections, fatigue, and kidney problems, all of which are related to the hematologic system.

Correct Answer: A

Rationale: Magnetic Resonance Imaging (MRI) is a specialized medical imaging technique that uses magnetic fields and radio waves to create detailed images of the organs and tissues within the body. In the context of the scenario provided, an MRI is ordered by the attending physician to validate the medical impression.

Correct Answer: A

Rationale: Acute narrow-angle glaucoma is a medical emergency that requires timely intervention to reduce intraocular pressure. Acetazolamide (Diamox) is a medication commonly used to treat this condition as it works as a carbonic anhydrase inhibitor, reducing the production of aqueous humor in the eye. By reducing the production of aqueous humor, acetazolamide helps decrease intraocular pressure rapidly, which is crucial in managing acute narrow-angle glaucoma. Other options listed, such as Furosemide (Lasix), Atropine, and Urokinase (Abbokinase), are not typically used in the treatment of acute narrow-angle glaucoma.
