When the findings of the study can be applied to all patients with MI under stress patients in the whole Philippines, it satisfies which of the following criteria in research?

Correct Answer: B

Rationale: Generalizability refers to the extent to which research findings and conclusions can be applied beyond the specific conditions of the study to a larger population or different settings. In this case, if the findings of a study on patients with myocardial infarction (MI) under stress can be applied to all such patients in the whole Philippines, it indicates that the study results are generalizable beyond the specific sample studied. Therefore, the criteria satisfied in this context is generalizability.

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: Molluscum contagiosum is a viral skin infection caused by the poxvirus. It typically presents as multiple, flesh-colored, dome-shaped papules with a central umbilication (dimple or depression in the center) on the skin. These lesions are often found on the trunk and extremities and can persist for several months. Molluscum contagiosum is commonly seen in children but can also occur in adults, especially those with weakened immune systems. The lesions are usually asymptomatic but can become inflamed or itchy in some cases. Treatment options include observation, topical therapies, cryotherapy, or curettage.

Correct Answer: C

Rationale: The presentation described in the question (sensation of fullness and pressure in the left ear, hearing loss, occasional tinnitus, retracted tympanic membrane with decreased mobility on pneumatic otoscopy) is suggestive of serous otitis media, also known as otitis media with effusion. Serous otitis media occurs when fluid accumulates in the middle ear without signs of infection. This buildup of fluid in the middle ear space can cause the tympanic membrane to retract and reduce its mobility on pneumatic otoscopy.

Correct Answer: C

Rationale: NSAIDs are known to increase the risk of gastrointestinal complications, particularly gastrointestinal bleeding, ulcers, and perforation. This risk is higher in patients who are elderly, have a history of peptic ulcer disease, are taking high doses of NSAIDs, or are using them for a prolonged period. It is important for the nurse to closely monitor the patient for signs and symptoms of gastrointestinal bleeding, such as abdominal pain, black or tarry stools, vomiting blood, and anemia. Prompt identification and management of these complications are essential to prevent serious consequences. Monitoring for gastrointestinal adverse effects is crucial when a patient is prescribed NSAIDs for managing conditions like osteoarthritis.

Correct Answer: A

Rationale: The correct nursing intervention for Almira would be to advise her to eat her meals. This is important in promoting her health and well-being, especially if she has been neglecting her own nutrition due to stress or caring for her son, Jay. Providing proper nutrition is a basic aspect of nursing care that supports the overall health and recovery of the patient. By encouraging Almira to prioritize her own nutrition, the nurse can help ensure that she has the physical strength and energy needed to take care of herself and her son effectively.

Correct Answer: B

Rationale: Acute otitis media is the most likely condition responsible for this presentation. The sudden onset of severe, unilateral ear pain, diminished hearing, and purulent otorrhea are classic symptoms of acute otitis media. Otoscopic examination revealing a bulging, erythematous tympanic membrane with obscured landmarks further supports the diagnosis. The bulging of the tympanic membrane is due to the accumulation of fluid and pus behind it, causing the characteristic appearance. Treatment typically involves antibiotics to help clear the infection and relieve symptoms. If left untreated, acute otitis media can lead to complications such as perforation of the eardrum or mastoiditis.

Correct Answer: B

Rationale: During the acute phase response, C-reactive protein (CRP) primarily serves to activate the complement system. CRP binds to phosphocholine on the surface of pathogens, allowing for the activation of the classical pathway of the complement system. This leads to the recruitment of immune cells, opsonization of pathogens, and enhancement of phagocytosis. The activation of the complement system by CRP plays a crucial role in the host defense against infections, aiding in the elimination of pathogens and the resolution of inflammation.

Correct Answer: C

Rationale: Postpartum hemorrhage is a serious complication that can occur within the first 24 hours after childbirth. It is the leading cause of maternal mortality worldwide. Therefore, during the immediate postpartum period, the first priority nursing intervention should be focused on observing for signs and symptoms of postpartum hemorrhage, such as excessive bleeding, abnormal vital signs, and changes in uterine tone. Early detection and prompt intervention can prevent severe complications and save the mother's life. Monitoring urinary output, taking vital signs, and checking level of responsiveness are important aspects of postpartum care but observing for postpartum hemorrhage takes precedence due to its critical nature.
