A patient presents with well-demarcated, hypopigmented macules with fine scaling, affecting the trunk and proximal extremities. The patient reports a history of sun exposure and outdoor activities. Which of the following conditions is most likely responsible for this presentation?
- A. Tinea versicolor
- B. Vitiligo
- C. Pityriasis rosea
- D. Seborrheic keratosis
Correct Answer: A
Rationale: The presentation described in the question is characteristic of tinea versicolor, a fungal skin infection caused by Malassezia furfur. The hypopigmented macules with fine scaling are often seen on the trunk and proximal extremities, particularly in areas that are more prone to sebum production. Patients with tinea versicolor may have a history of sun exposure and outdoor activities as the organism responsible for the infection thrives in warm, humid environments. Treatment typically involves the use of topical antifungal agents such as ketoconazole or selenium sulfide.

Ms. Nena suggested to use an analytic approach in their research. Which of the following statements BEST describes the analytic approach?
- A. Focuses on the community's health problems and issues
- B. Utilizes health indicators to define population health
- C. Views factors that influence health and by which interventions to improve health are directed
- D. Addresses the social determines of health to solve community's problems.
Correct Answer: C
Rationale: The analytic approach refers to a method that views factors that influence health and by which interventions to improve health are directed. In this case, utilizing an analytic approach in the research means looking into the root causes of the health problems in the community, analyzing various factors that contribute to the prevalence of obesity and heart ailments, and developing targeted interventions to address these issues effectively. This approach involves identifying underlying reasons for health problems and strategically planning interventions to improve the health outcomes of the community.
A patient presents with chest pain that occurs during heavy lifting or physical exertion and is relieved by rest. An electrocardiogram (ECG) may show transient ST-segment depression. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Stable angina
- B. Unstable angina
- C. Acute myocardial infarction
- D. Prinzmetal's angina
Correct Answer: A
Rationale: The given patient's symptoms of chest pain that occurs during heavy lifting or physical exertion and is relieved by rest are consistent with stable angina. Stable angina is characterized by predictable chest pain that occurs with exertion and is typically relieved by rest or nitroglycerin. The transient ST-segment depression on ECG is also a common finding in patients with stable angina, which reflects myocardial ischemia during episodes of chest pain triggered by exertion. In contrast, unstable angina is characterized by chest pain at rest or with minimal exertion that is of increasing frequency, severity, or duration. Acute myocardial infarction is associated with persistent ST-segment elevation or new Q-waves on ECG, and Prinzmetal's angina is characterized by chest pain at rest due to coronary artery spasm rather than exertion.
Before transferring the patient to the operating room (OR), the nurse notices a discrepancy between the surgical consent form and the planned procedure. What should the nurse do?
- A. Proceed with the planned procedure
- B. Inform the patient about the discrepancy
- C. Consult the surgeon for clarification
- D. Document the discrepancy in the patient's chart
Correct Answer: C
Rationale: When a nurse notices a discrepancy between the surgical consent form and the planned procedure, it is essential to consult the surgeon for clarification. The surgeon is the primary decision-maker regarding the surgical procedure and can provide insight into why the discrepancy exists and how to proceed. It is crucial to ensure that everyone is on the same page before moving forward with the surgery to prevent errors, ensure patient safety, and maintain legal and ethical standards. Consulting the surgeon allows for the issue to be addressed promptly and for the appropriate steps to be taken to resolve the discrepancy before proceeding with the surgery.
A pregnant woman presents with vaginal bleeding and crampy abdominal pain at 22 weeks gestation. On examination, the cervix is dilated, and the amniotic sac is visible at the cervical os. Which of the following conditions is the most likely cause of these symptoms?
- A. Ectopic pregnancy
- B. Threatened abortion
- C. Placenta previa
- D. Incompetent cervix
Correct Answer: D
Rationale: Incompetent cervix, also known as cervical insufficiency, is the most likely cause of the symptoms described. Incompetent cervix is a condition where the cervix begins to dilate and efface prematurely, typically in the second trimester, without contractions or labor. This can lead to painless cervical dilation and bulging of the amniotic sac into the vagina, which can cause vaginal bleeding and crampy abdominal pain. It is a leading cause of second-trimester pregnancy loss. Treatment may involve a cervical cerclage, a surgical procedure where the cervix is stitched closed to provide additional support.
What is the primary purpose of a cervical collar in the management of trauma patients?
- A. Maintaining spinal alignment.
- B. Immobilizing the cervical spine.
- C. Providing comfort and support.
- D. Facilitating airway management.
Correct Answer: B
Rationale: The primary purpose of a cervical collar in the management of trauma patients is to immobilize the cervical spine. This is crucial in cases of suspected cervical spine injury to prevent any further damage and to maintain spinal stability. By providing support and restricting movement in the cervical spine region, a cervical collar helps prevent potential spinal cord injuries and associated neurological deficits. It is essential to immobilize the cervical spine until a thorough evaluation can be carried out to determine the extent of injury, as any movement of the spine during this period can worsen the damage.
