The advanced practice registered nurse (APRN) knows which of the following systemic symptoms are usually associated with osteoarthritis (OA)?

Mental health disorders are frequently encountered in primary care settings and often present alongside or disguised by physical complaints. Many patients do not present with obvious psychiatric symptoms, which can lead to underdiagnosis or misinterpretation. Social stigma, comorbid medical conditions, and nonspecific symptom presentation all contribute to challenges in identification and management. Primary care providers play a key role in early recognition and intervention.

Rationale:
A. Stigma is a well-documented barrier in mental health care, as patients with psychiatric conditions may experience discrimination, misunderstanding, or social isolation. This stigma can affect help-seeking behavior, treatment adherence, and overall health outcomes. It remains a significant issue in both community and healthcare settings.

B. Mental health disorders are not rare; in fact, they are highly prevalent in outpatient and primary care populations. Conditions such as depression, anxiety, and substance use disorders are among the most common diagnoses encountered. Therefore, stating that they occur in less than 5% of outpatients is incorrect and underestimates their true prevalence.

C. Mental health disorders may be masked by physical symptoms such as fatigue, pain, gastrointestinal complaints, or sleep disturbances. Patients often present with somatic complaints rather than overt psychological symptoms, leading to misdiagnosis or delayed recognition. This overlap with medical conditions makes careful assessment essential in primary care.

D. The presentation of mental health disorders is often vague, nonspecific, and variable, which can make diagnosis challenging. Symptoms such as irritability, fatigue, or concentration difficulties may be attributed to other medical conditions. Without careful screening and assessment, important psychiatric clues can be easily overlooked by providers.

Assessment of hip stability in newborns is an essential component of early musculoskeletal screening to detect developmental dysplasia of the hip (DDH). Early identification is critical because untreated hip instability can lead to gait abnormalities, joint deformity, and long-term disability. Specific orthopedic maneuvers are used during infancy to assess whether the femoral head is dislocatable or reducible within the acetabulum. These tests are routinely performed until the infant begins walking, after which other signs become more apparent.

Rationale:
A. The Barlow test is used to assess whether the infant’s hip is dislocatable. It involves gently adducting the hip and applying posterior pressure to determine if the femoral head can be pushed out of the acetabulum. A positive Barlow test indicates hip instability and suggests developmental dysplasia of the hip requiring further evaluation and monitoring.

B. The Trendelenburg test assesses hip abductor muscle strength in older children and adults, not newborns. It evaluates pelvic stability during single-leg stance and is used in conditions such as hip dysplasia, muscular weakness, or nerve injury. It is not appropriate for detecting neonatal hip instability.

C. The Ortolani test is used to assess whether a dislocated hip can be reduced back into the acetabulum. It involves abducting the infant’s hips while applying gentle anterior pressure to feel or hear a “clunk” as the femoral head relocates. A positive Ortolani sign indicates a reducible dislocation consistent with developmental dysplasia of the hip.

D. The Leopold maneuver is an obstetric assessment technique used during pregnancy to determine fetal position, presentation, and lie within the uterus. It is not related to neonatal orthopedic examination or detection of hip instability. Therefore, it is not used in assessing developmental dysplasia of the hip.
