A patient presents with fever, headache, myalgia, and a skin lesion resembling a "bull's eye" rash at the site of a tick bite. Which of the following is the most likely causative agent?

Correct Answer: C

Rationale: The presentation described in the question, including the skin lesion resembling a "bull's eye" rash at the site of a tick bite, is characteristic of Lyme disease. Lyme disease is caused by the spirochete bacterium Borrelia burgdorferi, which is transmitted to humans through the bite of infected black-legged ticks (Ixodes scapularis). The symptoms of Lyme disease include fever, headache, myalgia, and the erythema migrans rash, which appears as a red circular rash with central clearing resembling a bull's eye.

Correct Answer: C

Rationale: The scenario described is suggestive of a meniscus injury. A twisting injury during sports activity leading to acute knee pain and swelling, accompanied by joint effusion and tenderness along the joint line, is commonly associated with meniscus tears. The meniscus is a C-shaped cartilage structure located between the femur and tibia in the knee joint, providing cushioning and stability. The symptoms of a meniscus tear typically include pain, swelling, joint line tenderness, and sometimes mechanical symptoms like locking or clicking. Treatment may involve rest, physical therapy, or in some cases, surgery to repair or remove the torn meniscus.

Correct Answer: B

Rationale: Phenomenology is a qualitative research design that focuses on exploring and understanding the lived experiences of individuals within their "life-worlds." It seeks to uncover the essence of a phenomenon as it is experienced subjectively by individuals, aiming to understand the underlying meanings and perspectives through in-depth interviews, observations, and reflections. In phenomenology, researchers aim to set aside their own biases and preconceptions to capture the essence of the participants' experiences as they see them. This approach allows researchers to gain insight into how individuals make sense of and interpret their world, providing rich and detailed accounts of unique human experiences.

Correct Answer: C

Rationale: Severe nausea and vomiting with a large volume of vomitus can indicate a serious underlying issue such as gastrointestinal obstruction or other medical emergencies. In this situation, it is crucial for the nurse to notify the physician immediately so that further assessment and appropriate management can be initiated promptly. Delay in seeking medical help can lead to complications and worsen the patient's condition. It is important to act quickly and involve the physician in situations where the patient's health may be at risk.

Correct Answer: A

Rationale: Rhinitis is inflammation of the nasal mucosa, and common clinical manifestations include nasal congestion (blockage or stuffiness), rhinorrhea (runny nose), and sneezing. These symptoms are often present in both allergic and non-allergic rhinitis. While headaches, sore throat, and fever can occur in some cases, they are not as specific to rhinitis as nasal congestion, rhinorrhea, and sneezing.

Correct Answer: B

Rationale: Cultural competence is the process of acquiring specific knowledge, skills, and attitudes to effectively work with individuals from diverse cultural backgrounds. It involves understanding and respecting the values, beliefs, languages, and practices of different cultures in order to provide appropriate care and services. Cultural competence goes beyond just learning about different cultures; it requires the development of skills and attitudes that promote effective communication, understanding, and collaboration with individuals of diverse backgrounds. This includes being aware of one's own biases, being open-minded, and adapting practices to be inclusive and respectful of cultural differences. Ultimately, cultural competence is essential in providing high-quality, respectful, and effective care to clients from various cultural backgrounds.

Correct Answer: D

Rationale: Respiratory depression resulting from drug overdose typically leads to a decrease in the respiratory rate, known as bradypnea. This is characterized by abnormally slow breathing, which can be dangerous as it may lead to decreased oxygen levels in the blood. Bradypnea indicates a slowing down of the respiratory drive, in contrast to hyperventilation, biot's respiration, or tachypnea. It is crucial for the nurse to monitor a patient experiencing respiratory depression for signs of bradypnea and intervene promptly to prevent further complications.

Correct Answer: A

Rationale: Selective IgA deficiency is a primary immunodeficiency disorder characterized by low or absent levels of immunoglobulin A (IgA) in the blood. Since IgA plays a crucial role in mucosal immunity and defense against pathogens at mucosal surfaces, individuals with this deficiency are more susceptible to recurrent bacterial infections, particularly of the respiratory and gastrointestinal tracts. In contrast, severe combined immunodeficiency (SCID) is a more severe immunodeficiency disorder affecting T and B lymphocytes, chronic granulomatous disease (CGD) is a disorder of phagocytes, and autoimmune hemolytic anemia is an autoimmune disease involving red blood cells, none of which are directly associated with selective IgA deficiency.

Correct Answer: B

Rationale: When managing a conscious patient with a severe nosebleed (epistaxis), the appropriate intervention is to have the patient sit upright and lean slightly forward to prevent blood from flowing into the throat and causing choking or swallowing. Pinching the soft part of the nose just below the bony part can help apply pressure to the bleeding vessel and stop the bleeding. This maneuver also helps compress the blood vessels in the nose, promoting clot formation and stopping the bleeding. It is important not to tilt the head back as this can cause blood to flow into the throat and potentially lead to swallowing, choking, or aspiration. Packing the nose with cotton gauze should be done by medical professionals if the bleeding does not stop with direct pressure. Applying direct pressure to the forehead is not effective for managing nosebleeds; pressure should be applied to the nostrils instead.
