A very popular means of early detection of breast cancer is:

Correct Answer: D

Rationale: Breast self-examination (BSE) is a very popular means of early detection of breast cancer as it involves women being aware of how their breasts look and feel to detect any changes such as lumps, swelling, or other abnormalities. By performing regular self-examinations, women can identify any potential issues early on and seek medical advice promptly. While mammograms (X-ray) and clinical breast exams by healthcare providers are also important screening methods for detecting breast cancer, BSE is particularly valuable as women can perform it on a regular basis at home, thus increasing the chances of identifying any concerning changes promptly. It is recommended that women perform BSE monthly to become familiar with their breast tissue and notice any changes over time.

Correct Answer: C

Rationale: Petechiae are small, pinpoint, red or purple spots on the skin caused by bleeding into the skin. In dark-skinned individuals, it can be challenging to visualize petechiae due to the pigmentation of the skin. However, one of the best places to observe for the presence of petechiae in dark-skinned individuals is the oral mucosa, specifically the inner lining of the mouth. The oral mucosa is usually lighter in color compared to the skin, making it easier to identify petechiae in this area. Palms and soles may also be a good place to observe for petechiae, but the oral mucosa is typically the preferred site for examination in dark-skinned individuals.

Correct Answer: B

Rationale: Playing in sand at the park can increase the risk of lead poisoning in children because sand can be contaminated with lead particles from various sources such as old paint, industrial pollution, or leaded gasoline residues. When children play in sand, they may accidentally ingest the contaminated particles while handling or playing with the sand. This ingestion can lead to lead poisoning, as even small amounts of lead can be harmful to children's health. Therefore, playing in sand at the park poses a higher risk of lead exposure compared to the other activities listed.

Correct Answer: A

Rationale: Patients with multiple myeloma are at an increased risk of bleeding due to low levels of platelets, which play a key role in blood clotting. Uncontrolled bleeding can occur in multiple myeloma patients, leading to serious complications such as hemorrhage and anemia. Therefore, the nurse should monitor for signs of bleeding, such as easy bruising, petechiae, or prolonged bleeding from minor cuts or procedures, and take appropriate interventions to manage and prevent further bleeding episodes in the patient with multiple myeloma. Monitoring for and addressing uncontrolled bleeding is crucial in ensuring the safety and well-being of the patient.

Correct Answer: B

Rationale: Tetralogy of Fallot is a congenital heart defect characterized by four abnormalities - pulmonary stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. The pulmonary stenosis in Tetralogy of Fallot results in decreased pulmonary blood flow, leading to cyanosis. The other choices (Atrial septal defect, Ventricular septal defect, Patent ductus arteriosus) do not result in decreased pulmonary blood flow.
