Correct Answer: B

Rationale: Performing a sigmoidoscopy, which is a procedure to examine the lower part of the colon and rectum, during a health screening event at a community center may not be practical for several reasons. Firstly, sigmoidoscopy is relatively invasive compared to other screening methods for colon cancer, such as fecal occult blood tests or colonoscopy. Secondly, it can be expensive to perform, especially in a community setting where cost-effectiveness is an important consideration. Therefore, Nurse Filomena would likely point out the invasiveness and cost factors to explain why a sigmoidoscopy may not be suitable for a health screening event at a local community center.

Correct Answer: A

Rationale: At the concrete operational stage according to Piaget's theory, children typically demonstrate logical thinking abilities and are able to understand and work with concrete objects and events. They can also grasp concepts such as conservation and classification. These children are able to think logically about concrete events but may still struggle with abstract and hypothetical situations. Therefore, Belle, functioning at the concrete operational stage, would exhibit behaviors such as thinking logically and being able to see possibilities, as described in option A.

Correct Answer: C

Rationale: Maintaining patient confidentiality is a foundational principle in healthcare ethics. Nurses are obligated to keep all information about patients confidential, which means not disclosing any patient-related information to unauthorized individuals. This includes refraining from discussing patient cases with others who are not directly involved in the care of the patient. Sharing patient information without consent can be a breach of trust and privacy, which can have legal and ethical implications. Therefore, in order to uphold the principle of confidentiality, nurses must keep all matters about the patient as a secret.

Correct Answer: C

Rationale: Nurse Sandra should consider Cindy, 7 years old who has been absent due to skin lesions, as a priority for home visitation. Skin lesions can indicate potential health issues that need to be addressed promptly. Cindy's frequent absences could be a sign that her condition is affecting her school attendance and overall well-being. By conducting a home visit, Nurse Sandra can assess Cindy's living environment, provide appropriate care recommendations, and ensure that she receives necessary medical attention. This proactive approach can help address Cindy's health concerns and support her academic performance.

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.
