Correct Answer: C

Rationale: The symptoms of polyuria (excessive urination), polydipsia (excessive thirst), and polyphagia (excessive hunger) are classic signs of diabetes mellitus. In this case, the presence of hyperglycemia (high blood sugar) and glycosuria (glucose in the urine) further support the diagnosis of diabetes mellitus. Insulin deficiency or resistance in diabetes leads to impaired glucose utilization and excessive glucose in the bloodstream, causing the classic symptoms observed in the patient. Hyperthyroidism, hypothyroidism, and Cushing's syndrome do not typically present with the hallmark symptoms of polyuria, polydipsia, and polyphagia associated with uncontrolled diabetes mellitus.

Correct Answer: B

Rationale: During pulmonary rehabilitation for COPD, smoking cessation should not be avoided but instead strongly encouraged. Smoking cessation is a crucial component in managing COPD and improving lung function. Continued smoking can exacerbate COPD symptoms and hinder the progress made through rehabilitation efforts. Therefore, it is essential for patients to quit smoking while undergoing pulmonary rehabilitation to maximize the benefits of the program and improve their overall lung health.

Correct Answer: B

Rationale: As an epidemiology nurse, Nurse Rona's primary function and responsibility is to implement public health surveillance. Epidemiology nurses play a crucial role in monitoring and controlling the spread of diseases within communities. This involves conducting surveillance activities to identify patterns of disease occurrence, investigating outbreaks, collecting and analyzing data, and collaborating with various stakeholders to develop strategies for disease prevention and control. While providing nursing care to sick residents is important, the primary focus of an epidemiology nurse is on population-based health issues rather than individual patient care. Additionally, while Nurse Rona may assist epidemiologists in making reports and follow up cases and contacts, her main role is to implement public health surveillance to protect and promote the health of the community as a whole.

Correct Answer: A

Rationale: Colles' fracture is a type of distal radius fracture characterized by a break of the radius bone in the forearm close to the wrist. In a Colles' fracture, the distal fragment of the fractured radius bone gets displaced dorsally, meaning it shifts upwards towards the back of the hand, creating a characteristic "dinner fork" deformity when viewed from the side. This dorsal displacement results in a visible bump on the back of the wrist and a noticeable deformity when compared to the uninjured side.

Correct Answer: B

Rationale: Ectopic pregnancy is a common complication of untreated gonorrhea or chlamydia infection in women. This occurs when a fertilized egg implants and grows outside the uterus, typically in one of the fallopian tubes. Both gonorrhea and chlamydia can lead to scarring of the fallopian tubes due to untreated inflammation and infection. This scarring may obstruct the fallopian tubes, making it difficult for the fertilized egg to travel to the uterus for implantation. As a result, the egg may implant and grow in the fallopian tube, leading to an ectopic pregnancy. Ectopic pregnancies are dangerous and can result in serious complications for the woman, including rupture of the fallopian tube, internal bleeding, and potentially life-threatening situations. It is crucial to seek prompt treatment for gonorrhea and chlamydia to prevent such severe outcomes.
