A client self-medicated with 6 tablespoons of cough medicine prior to coming to the emergency room.

How many mL did the client take? . . .

Choice A rationale

Family history reflects the inherited susceptibility to specific conditions based on the health patterns of biological relatives. While it provides critical data for screening and early detection, an individual cannot change their ancestral lineage or the health events of their parents and siblings. Because these genetic predispositions are fixed at birth, they are classified as non-modifiable risk factors in epidemiological studies and clinical preventative health assessments.

Choice B rationale

Chronological age is a primary non-modifiable risk factor because the physiological aging process involves progressive cellular decline and increased vulnerability to chronic diseases. As time passes, the cumulative exposure to environmental stressors and the natural reduction in homeostatic efficiency cannot be reversed. In disease pathology, age-related changes in organ function and immune response are inevitable, making it a constant variable that healthcare providers must account for without the possibility of alteration.

Choice C rationale

Genetics involves the specific DNA sequences and chromosomal structures inherited from biological parents that determine various health traits and disease predispositions. Genomic science confirms that while lifestyle can influence gene expression through epigenetics, the underlying genetic code itself remains unchanged throughout a person's life. Therefore, genetic mutations or hereditary markers for conditions like cystic fibrosis or certain cancers are fundamental non-modifiable factors that dictate baseline health risks.

Choice D rationale

Sunbathing is a behavioral choice involving exposure to ultraviolet radiation, which is a known carcinogen for skin cells. Unlike age or genetics, an individual can choose to limit sun exposure, use protective clothing, or apply sunscreen to reduce the risk of developing melanoma or basal cell carcinoma. Because this behavior is under the direct control of the individual and can be altered through education and lifestyle changes, it is classified as a modifiable risk factor.

Choice A rationale

Lecture is a passive teaching method where the educator provides information to the learner without requiring immediate participation or verification of understanding. It is useful for delivering large amounts of information to groups but does not allow the nurse to assess the client's actual retention or physical ability to perform a task. In this scenario, the nurse is actively seeking a demonstration of understanding from the client, which exceeds the scope of a lecture.

Choice B rationale

Role play involves the nurse and client acting out a scenario to practice social or communication skills. While it can be used for teaching, it is usually focused on emotional responses or complex interpersonal interactions rather than the verification of a specific technical procedure like eye drop instillation. The nurse in this question is asking for a verbalization of steps rather than acting out a situational scenario between two distinct characters or roles.

Choice C rationale

Query and answer, or question and answer, is a method used to clarify specific points or address gaps in knowledge. While the nurse is asking the client a question, the specific intent of asking the client to explain the entire procedure back is a structured pedagogical technique. Query and answer sessions are typically more fragmented and focused on individual facts rather than a comprehensive assessment of the client's ability to synthesize and repeat instructions.

Choice D rationale

Teach-back is a formal evidence-based communication loop where the nurse asks the client to explain the information or procedure in their own words. This method confirms that the client understands the teaching and allows the nurse to correct any misconceptions immediately. It is the gold standard for verifying health literacy and ensuring safety in self-administration of medications. By having the client explain the steps, the nurse ensures the instructions were clear and understood.
