In response to a question regarding the use of alcohol, a patient asks the nurse why the nurse needs to know. What is the reason for needing this information?

Alcohol can interact with medications and can make some diseases worse

This information is necessary to determine the patient’s reliability

This information is not necessary unless a drinking problem is obvious

The nurse needs to be able to teach all patients to avoid any alcohol consumption

Answer and Explanation

The Correct Answer is A

Choice A reason: Alcohol can interact with medications, altering their metabolism via liver enzymes (e.g., CYP450), and exacerbate conditions like liver disease or hypertension. This information is critical for safe treatment planning, making it the primary reason for inquiry.

Choice B reason: Assessing patient reliability is not the purpose of asking about alcohol use. This question focuses on clinical implications, not trustworthiness, as alcohol’s effects on health and medications are the priority, making this an incorrect rationale.

Choice C reason: Alcohol use is relevant even without an obvious drinking problem, as even moderate consumption can affect medication efficacy or disease progression. Dismissing this question unless a problem is evident overlooks potential risks, making this incorrect.

Choice D reason: Teaching all patients to avoid alcohol is not universally necessary, as moderate use may be safe for some. The inquiry aims to identify specific risks, like drug interactions, not to enforce blanket abstinence, making this an incorrect reason.

Correct Answer is B

Explanation

Choice A reason: Dorsiflexion and toe fanning indicate a Babinski sign, a reflex test, not Romberg’s sign. Romberg’s sign involves balance issues with closed eyes, so this is incorrect for the neurological assessment.

Choice B reason: A positive Romberg’s sign is observed when a patient sways significantly or loses balance when standing with feet together and eyes closed, indicating impaired proprioception or cerebellar function. This is the correct observation for the test.

Choice C reason: Rhythmic eye twitching (nystagmus) is unrelated to Romberg’s test, which assesses balance. Swaying with closed eyes defines a positive Romberg’s, sign, so this is incorrect for the outcome.

Choice D reason: Inability to point fingers to a reference tests coordination, not the Romberg’s test, which focuses on balance with eyes closed. Significant swaying is the correct sign, so this is incorrect.

A. 5 lumbar B. 12 cervical C. 7 sacral D. 5 thoracic

Correct Answer is A

Explanation

Choice A reason: The human spinal column has 33 vertebrae: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral (fused), and 4 coccygeal (fused). The 5 lumbar vertebrae, located in the lower back, support significant weight and allow flexibility, making this choice correct for the vertebral count.

Choice B reason: The cervical spine consists of 7 vertebrae, not 12, which are designed for mobility and support of the head. The incorrect count of 12 aligns with the thoracic vertebrae, making this choice scientifically inaccurate for the cervical region.

Choice C reason: The sacral region has 5 vertebrae, which fuse into the sacrum in adults, not 7. The sacrum forms part of the pelvis, providing stability. The incorrect count of 7 corresponds to the cervical vertebrae, making this choice incorrect.

Choice D reason: The thoracic spine comprises 12 vertebrae, not 5, which articulate with the ribs to form the thoracic cage. The incorrect count of 5 aligns with the lumbar or sacral vertebrae, rendering this choice inaccurate for the thoracic region.
