Correct Answer: A

Rationale: The correct answer is the 'structure of the health care system and family structure'. Scholars suggest that the reasons families are having difficulty providing health care for their members lie with both the structure of the health care system and the family structure. Major factors explaining differences in utilization patterns of medical services include the lack of healthcare insurance coverage, lack of services for special populations (such as teenage males), perception by families of the health care system and the health care provider, and lack of partnership between health care providers and families in mutually addressing health care issues. Choices B, C, and D are incorrect as they do not address the fundamental reasons related to the health care system and family structure as discussed in the provided extract.

Correct Answer: B

Rationale: The correct answer is 'overreaction to stimuli from the surroundings.' Children with attention deficit disorder often exhibit hypersensitivity to stimuli, leading to overreactions. Slow speech development is not a hallmark of attention deficit disorder; it is more associated with other learning disabilities. While children with this disorder may have difficulty focusing, they can usually carry on a conversation. Concrete thinking is not a common characteristic of attention deficit disorder, as individuals with this disorder may struggle with abstract thinking and impulsivity.

Correct Answer: C

Rationale: When assessing the carotid artery of a client with cardiovascular disease, the nurse should listen to the carotid artery using the bell of the stethoscope to assess for bruits. This is crucial in detecting abnormal sounds that may indicate underlying pathology. Palpating the carotid artery in the upper third of the neck can trigger a vagal response, leading to a decrease in heart rate, which is undesirable. Palpating both arteries simultaneously can disrupt blood flow to the brain. Instructing the client to take slow, deep breaths is unnecessary and not a standard practice during carotid artery assessment.

Correct Answer: D

Rationale: The correct answer is 'Ocular movements.' Moving the eyes through the six cardinal fields of gaze evaluates the function of the eye muscles, such as the medial rectus muscle, superior rectus muscle, superior oblique muscle, lateral rectus muscle, inferior rectus muscle, and inferior oblique muscle. Normal movement in these fields indicates proper ocular movements. Near vision is assessed using a handheld vision screener, central vision with a Snellen chart, and peripheral vision through the confrontation test. Therefore, the evaluation of ocular movements through the six cardinal fields of gaze specifically assesses this aspect of eye function. Choices A, B, and C are incorrect as they pertain to different aspects of vision function that are evaluated using distinct assessment methods, not through the six cardinal fields of gaze.

Correct Answer: D

Rationale: The correct answer is Fluoxetine. Among the options provided, Fluoxetine is the medication least likely to cause tinnitus. Gentamicin, Lasix, and Aspirin are known ototoxic medications that have a potential side effect of causing tinnitus, a ringing in the ear. Gentamicin is an antibiotic, Lasix is a diuretic, and Aspirin is a common pain reliever that can lead to tinnitus. In contrast, Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) primarily used as an antidepressant, and it has a lower risk of causing tinnitus compared to the other options.
