The blood protein involved in the immune system is:

Correct Answer: C

Rationale: Globulin is the blood protein involved in the immune system. There are different types of globulins, including immunoglobulins (antibodies) that play a crucial role in the body's defense against infections. These antibodies bind to foreign substances, such as bacteria and viruses, helping the immune system to recognize and destroy them. Thrombin is a clotting protein, albumin is a protein responsible for maintaining osmotic balance in the blood, and hemoglobin is a protein found in red blood cells that carries oxygen.

Correct Answer: A

Rationale: Clients who are taught skills such as measuring blood glucose, taking blood pressure, changing dressings, and bathing infants are learning skills that involve physical movement and coordination. These activities require the integration of mental and physical skills, and they fall under the psychomotor domain of learning. In this domain, individuals develop physical skills and coordination through practice and repetition. The psychomotor domain is one of the three domains of learning, along with the cognitive domain (which involves knowledge and intellectual skills) and the affective domain (which involves emotions, values, and attitudes).

Correct Answer: B

Rationale: Medical records are typically required to be retained for a certain period of time as mandated by legal and regulatory requirements. The retention period for medical records is generally between 5 to 10 years, depending on the jurisdiction and specific regulations governing healthcare facilities. Keeping medical records for this duration ensures that they are available for reference, audits, legal purposes, and continuity of care for patients. Storing medical records for an adequate length of time also helps in ensuring continuity of care and tracking patients' medical history over time, which is crucial for quality healthcare delivery. Therefore, storing charts in the Medical Records or storage room for at least 5-10 years aligns with standard practices in healthcare compliance and patient care.

Correct Answer: A

Rationale: Endometriosis is a condition characterized by the abnormal growth of endometrial tissue outside the uterus. One common symptom of endometriosis is excessive menstrual bleeding, known as menorrhagia. This excessive bleeding is due to the presence of endometrial tissue in abnormal locations, leading to inflammation, scarring, and blood accumulation. In severe cases, endometriosis can lead to the formation of adhesions, cysts, and scar tissue, causing significant pain and fertility issues for affected individuals. Endometrial hyperplasia, leiomyomas (uterine fibroids), and adenomyosis are other gynecological conditions, but they do not involve the abnormal proliferation of endometrial tissue outside the uterus like endometriosis does.

Correct Answer: B

Rationale: Type I IgE-mediated immediate hypersensitivity reactions, such as anaphylaxis, are promptly managed with epinephrine. Epinephrine is the first-line treatment for anaphylaxis as it helps counteract the severe symptoms by relaxing the muscles in the airways, constricting blood vessels, and decreasing swelling. It acts quickly to reverse the potentially life-threatening effects of the allergic reaction and is crucial in managing anaphylaxis effectively. Other medications like antihistamines (e.g., diphenhydramine) and corticosteroids may be used as adjuncts, but epinephrine remains the primary treatment for immediate hypersensitivity reactions.

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.

Correct Answer: C

Rationale: The nurse's best approach to address the patient's confusion about their medication regimen is to use a teach-back method to assess understanding and clarify any misconceptions. This method involves the nurse asking the patient to explain in their own words how they will take their medications, what each medication is for, and any potential side effects they should watch for. By using the teach-back method, the nurse can confirm the patient's comprehension and correct any misunderstandings in a supportive and non-judgmental manner. This approach promotes patient education, empowerment, and adherence to the medication regimen. Providing written instructions alone (Choice A) may not be sufficient if the patient has difficulty reading or understanding written information. Explaining the medication regimen using complex medical terminology (Choice B) can further confuse the patient, making it harder for them to grasp the information. Dismissing the patient's concerns and reassuring them that the medication is safe (Choice D) does not address the root of the issue and

Correct Answer: B

Rationale: For a displaced femoral neck fracture, the most appropriate surgical procedure is usually an open reduction and internal fixation (ORIF). This procedure involves making an incision to reposition the fractured bone fragments and securing them in place with screws or other fixation devices. ORIF allows for better alignment of the fracture, which is crucial for proper healing and minimizing the risk of complications like avascular necrosis or nonunion. Closed reduction and internal fixation (CRIF) may not be as effective for displaced femoral neck fractures due to the complex nature of the fracture and the need for precise realignment and stability provided by an open surgical approach. External fixation is less commonly used for femoral neck fractures and is typically reserved for certain specific cases where internal fixation is not feasible. Closed reduction alone is unlikely to provide adequate stability for a displaced femoral neck fracture and is generally not recommended as the primary surgical treatment for this type of injury.

Correct Answer: A

Rationale: The clinical presentation of fever, chills, headache, and myalgia following a trip to sub-Saharan Africa is highly suggestive of malaria, which is caused by the Plasmodium species. Specifically, the presence of intraerythrocytic ring forms and trophozoites on blood smear examination points towards Plasmodium falciparum as the most likely causative agent.
