A patient presents with a pruritic, annular rash with fine scaling and central clearing, affecting the trunk and proximal extremities. The patient reports recent exposure to a new soap and laundry detergent. Which of the following conditions is most likely responsible for this presentation?

Correct Answer: B

Rationale: The presentation described is consistent with nummular eczema, also known as discoid eczema. Nummular eczema typically presents as circular or oval-shaped patches of eczematous rash with fine scaling and central clearing. It is often pruritic and can be triggered by exposure to irritants such as new soaps or laundry detergents. The distribution on the trunk and proximal extremities is also typical for nummular eczema. Tinea corporis (ringworm) would present with a more raised, scaly, and well-defined border with central clearing. Pityriasis rosea presents with a herald patch followed by smaller oval or round lesions in a "Christmas tree" distribution. Lichen planus would present with polygonal, purplish, flat-topped papules typically located on flexural surfaces and extremities.

Correct Answer: C

Rationale: Incident Reports (IRs) must be summarized monthly and stored in a secured cabinet for several reasons. Firstly, summarizing the IRs monthly allows for a consolidated overview of the incidents that have occurred, highlighting any recurring patterns or trends that may need to be addressed. By storing the summarized IRs in a secured cabinet, the information is kept confidential and protected from unauthorized access. This practice also ensures that the reports are organized and easily accessible for future reference or audits. Storing the IRs on an open cabinet, table top, or with a classification system that may not be easily understandable can lead to potential breaches of confidentiality or difficulty in retrieving and understanding the information when needed.

Correct Answer: B

Rationale: In Stage I of Hodgkin's disease, the most commonly seen early symptom is usually unexplained fever and night sweats. Other common symptoms at this stage may include unexplained weight loss, itching, and enlarged lymph nodes in the neck, underarms, or groin. Chest and back pains, subnormal body temperature, and swelling of extremities are not typically early indicators of Stage I Hodgkin's disease.

Correct Answer: B

Rationale: Opsonization is a process in the immune response where opsonins, which are proteins such as antibodies and complement proteins, bind to pathogens such as bacteria, making them more easily recognized and engulfed by phagocytic cells like macrophages and neutrophils. This coating of pathogens by opsonins enhances the efficiency of phagocytosis, helping in the elimination of pathogens from the body. Opsonins do not facilitate cell lysis, neutralize toxins, or stimulate histamine release; their main function is to tag pathogens for phagocytosis.

Correct Answer: A

Rationale: The patient's symptoms of chest pain occurring during heavy lifting or physical exertion and being relieved by rest are classic characteristics of stable angina. Stable angina is caused by transient myocardial ischemia due to a fixed coronary artery obstruction. Typically, the pain is predictable and reproducible, occurring with exertion and relieved by rest. The transient ST-segment depression on ECG is also a common finding in stable angina, reflecting myocardial ischemia during episodes of chest pain.

Correct Answer: B

Rationale: Guava leaves are recommended by the Department of Health as a remedy for cough due to their natural expectorant properties. The leaves contain compounds that help to loosen mucus and make it easier to expel, providing relief from cough and congestion. Guava leaves are commonly used in traditional medicine for respiratory conditions such as cough, bronchitis, and asthma. They help soothe the throat, reduce inflammation, and promote overall respiratory health. It is important to note that while guava leaves can be a helpful remedy for cough, they should be used in conjunction with other treatments as advised by healthcare professionals for best results.

Correct Answer: C

Rationale: When providing health education to a patient, using clear and simple language is an essential aspect of effective communication. Medical terminology can be confusing and overwhelming for individuals without a medical background. By using language that the patient can easily understand, you improve their comprehension of the information being conveyed. Speaking quickly or using complex terms can actually hinder communication and may lead to misunderstanding. Clear and simple language helps ensure that the patient fully grasps the information and can make informed decisions about their health.

Correct Answer: B

Rationale: The laboratory test used to monitor the therapeutic effect of warfarin therapy is the International Normalized Ratio (INR). Warfarin is a commonly prescribed anticoagulant medication that works by inhibiting the action of vitamin K-dependent clotting factors. Maintaining the INR within the target range specific to the indication for anticoagulation (e.g., DVT prevention or treatment) is essential to balance the risk of bleeding and clotting.

Correct Answer: D

Rationale: Acute respiratory distress syndrome (ARDS) is a severe condition characterized by widespread inflammation in the lungs leading to increased pulmonary vascular permeability, non-cardiogenic pulmonary edema, and respiratory failure. In ARDS, the alveolar-capillary barrier is disrupted, resulting in fluid accumulation in the alveoli and impaired gas exchange.
