Correct Answer: B

Rationale: The correct developmental milestone for a 6-month-old child that should be screened during a routine office visit is rolling over. At this age, infants typically start rolling over from their stomach to their back and vice versa. Sitting up usually occurs between 7 and 8 months, creeping between 9 and 10 months, and standing while holding something between 8 and 10 months. Therefore, choices A, C, and D are developmentally appropriate but not typically expected at 6 months of age.

Correct Answer: A

Rationale: Serotonin syndrome, caused by an excess of serotonin, typically presents with symptoms such as altered mental status (confusion), neuromuscular abnormalities (tremors), and autonomic dysfunction (fever). Edema, which refers to swelling caused by fluid retention in the body tissues, is not a common symptom associated with serotonin syndrome. Therefore, the correct answer is 'edema.' Choice A, 'edema,' is the correct answer as it is not typically seen in serotonin syndrome. Choice B, 'fever,' is a symptom of serotonin syndrome, as it can cause autonomic dysfunction. Choice C, 'confusion,' is a common symptom due to altered mental status in serotonin syndrome. Choice D, 'tremors,' is also a common symptom due to neuromuscular abnormalities in serotonin syndrome.

Correct Answer: C

Rationale: The correct answer is, "I can't wait to get back to my nightly glass of wine,"? as phenobarbital should not be taken with alcohol as it is a barbiturate. Alcohol may increase the sedative effect, posing risks to the patient's safety. Choice A, "I will need to avoid eating excessive leafy greens,"? is unrelated to phenobarbital and not a cause for reinforced teaching. Choice B, "It's best to take this medication with food,"? is a general instruction and not specific to phenobarbital. Choice D, "I should try to take this medication at the same time every day,"? is a common recommendation for medication adherence but does not highlight a specific concern related to phenobarbital.

Correct Answer: A

Rationale: The correct answer is 'Immunizations may be started at any age.' While there is a recommended immunization schedule, immunizations can be initiated at any age. It is essential to emphasize the flexibility in starting immunizations. The statement 'The recommended immunization schedule should be followed' is too rigid; while recommended, there is flexibility in initiation. Choice C is correct as an interrupted series can be continued without restarting. The statement 'Delaying the start of vaccines does not increase the risk of reaction' is correct. Delaying does not increase the risk of reaction; in fact, it is important to start immunizations to protect the child and the community.

Correct Answer: D

Rationale: When interpreting visual acuity testing results using the Snellen chart, the recorded numeric fraction represents the distance the client is standing from the chart and the distance a normal eye could read that particular line. A reading of 20/80 means that the client can read at 20 feet what a client with normal vision can read at 80 feet. This indicates visual impairment but does not meet the criteria for legal blindness, which is defined as best-corrected vision in the better eye of 20/200 or worse. Normal visual acuity is 20/20. Therefore, the correct interpretation is that the client can read at a distance of 80 feet what a client with normal vision can read at 20 feet. Choice A is incorrect because 20/80 does not meet the criteria for legal blindness. Choice B is incorrect as the client's vision is impaired. Choice C is incorrect because it reverses the interpretation of the fraction.
