Nokea
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?
- A. Tinea corporis (ringworm)
- B. Nummular eczema
- C. Pityriasis rosea
- D. Lichen planus
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.

A patient admitted to the ICU develops severe sepsis with refractory hypotension despite adequate fluid resuscitation. What intervention should the healthcare team prioritize to manage the patient's septic shock?
- A. Administer vasopressor medications to restore vascular tone.
- B. Perform blood cultures to identify the causative pathogen.
- C. Initiate broad-spectrum antibiotics targeting likely pathogens.
- D. Recommend prophylactic anticoagulation to prevent thrombosis.
Correct Answer: A
Rationale: In the scenario described, the patient is experiencing refractory hypotension despite adequate fluid resuscitation, indicating the presence of septic shock. In septic shock, systemic vasodilation and vascular hyporesponsiveness contribute to hypotension. Therefore, the primary management approach is to restore vascular tone and blood pressure to maintain organ perfusion. Administering vasopressor medications (Choice A) is the crucial intervention to achieve this goal. Vasopressors, such as norepinephrine or vasopressin, constrict blood vessels and increase blood pressure, helping to stabilize the patient in septic shock. While options B and C (performing blood cultures and initiating broad-spectrum antibiotics) are important for identifying the causative pathogen and treating the infection, they are secondary to the immediate need for hemodynamic support in septic shock. Prophylactic anticoagulation (Choice D) is not the primary intervention for
Who should be involved in quality improvement measures?
- A. Everyone
- B. Professional staff
- C. Management staff
- D. Consumers
Correct Answer: A
Rationale: Quality improvement measures are most effective when everyone within an organization is involved. This includes not only professional and management staff but also consumers or customers who are directly impacted by the products or services being provided. By involving everyone, a more comprehensive and diverse perspective can be gained, leading to better identification of areas for improvement and more successful implementation of quality improvement initiatives. Additionally, by involving all stakeholders, there is a greater buy-in and commitment to the process, increasing the likelihood of sustainable improvements being made.
A patient with osteoarthritis of the hip undergoes surgical intervention with a total hip arthroplasty (THA). Which postoperative complication should the healthcare team monitor for in the immediate postoperative period?
- A. Deep vein thrombosis (DVT)
- B. Delayed wound healing
- C. Pulmonary embolism
- D. Prosthetic joint infection
Correct Answer: A
Rationale: Following total hip arthroplasty (THA), patients are at an increased risk of developing deep vein thrombosis (DVT) due to factors such as immobility, surgery-related vascular damage, and hypercoagulability. DVT refers to the formation of blood clots in the deep veins, typically in the lower extremities. These clots can break loose and travel to the lungs, causing a potentially life-threatening condition called pulmonary embolism (PE). Therefore, monitoring for signs and symptoms of DVT is crucial in the immediate postoperative period to promptly detect and prevent the development of complications such as PE. Common signs of DVT include leg swelling, pain, warmth, and redness. Additionally, healthcare providers may employ preventive measures such as early ambulation, compression stockings, and anticoagulant therapy to reduce the risk of DVT post-THA surgery.
A patient presents with sudden-onset severe headache, altered mental status, and focal neurological deficits. Imaging reveals a hemorrhagic lesion within the subarachnoid space. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Ischemic stroke
- B. Subdural hematoma
- C. Intracerebral hemorrhage
- D. Subarachnoid hemorrhage
Correct Answer: D
Rationale: A subarachnoid hemorrhage is characterized by bleeding within the subarachnoid space, the area between the arachnoid mater and the pia mater surrounding the brain. Patients typically present with a sudden-onset severe headache, altered mental status, and focal neurological deficits due to the mass effect of the blood in the subarachnoid space. Imaging, such as a CT scan, can confirm the presence of the hemorrhagic lesion. Ischemic stroke results from a blockage in the blood vessels supplying the brain, leading to tissue infarction and neurological deficits. Subdural hematoma is a collection of blood between the dura mater and the arachnoid mater, commonly seen following head trauma. Intracerebral hemorrhage involves bleeding within the brain tissue itself, often leading to focal neurological deficits.
A patient presents with hoarseness, dysphonia, and occasional throat pain. Direct laryngoscopy reveals vocal cord nodules. Which of the following interventions is most appropriate for managing this condition?
- A. Vocal cord polypectomy
- B. Vocal cord injection with corticosteroids
- C. Voice therapy and vocal hygiene education
- D. Partial laryngectomy
Correct Answer: C
Rationale: Vocal cord nodules are benign growths on the vocal cords, typically caused by vocal abuse or misuse. The most appropriate intervention for managing vocal cord nodules is voice therapy and vocal hygiene education. Voice therapy aims to correct vocal habits and techniques that contribute to the formation of nodules, while vocal hygiene education focuses on maintaining vocal health through proper hydration, rest, and avoiding behaviors that strain the vocal cords. These interventions have been shown to be effective in reducing and eliminating vocal cord nodules without the need for surgical intervention. Surgery, such as vocal cord polypectomy or injection with corticosteroids, is typically reserved for cases that do not respond to conservative management or if there are significant complications. Partial laryngectomy is a more extensive surgical procedure that is not typically indicated for vocal cord nodules.
