The healthcare provider prescribes enoxaparin sodium 80 mg SUBQ three times daily. The nurse is preparing a preloaded 1 mL syringe labeled “Enoxaparin sodium injection, USP 60 mg/0.6 mL.”

How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Choice A reason:

Decreased night vision is a significant concern for clients receiving miotics for open-angle glaucoma. Miotics, such as pilocarpine, work by constricting the pupil (miosis), which can reduce the amount of light entering the eye. This effect is particularly problematic in low-light conditions, leading to decreased night vision and increasing the risk of injury due to poor visibility

Choice B reason:

Increased sensitivity to light, also known as photophobia, can occur with the use of miotics, but it is not the primary concern related to the risk of injury. While photophobia can cause discomfort and avoidance of bright environments, it does not directly contribute to the risk of injury as significantly as decreased night vision.

Choice C reason:

Increased frequency of lacrimation (tearing) can be a side effect of miotics, but it is not a major factor in the risk of injury. Excessive tearing can cause discomfort and blurred vision temporarily, but it does not pose a significant risk for injury compared to decreased night vision.

Choice D reason:

Diminished color perception is not a common side effect of miotics. Miotics primarily affect the pupil size and accommodation, rather than color vision. Therefore, this choice is not relevant to the risk of injury associated with the use of miotics.

Choice A reason: Constipation is typically a symptom of hypothyroidism, not hyperthyroidism. If a client is taking too much levothyroxine, they are more likely to experience symptoms of hyperthyroidism, such as diarrhea, rather than constipation.

Choice B reason: Intolerance to cold is a common symptom of hypothyroidism, indicating that the thyroid hormone levels are too low. If the client is taking too much levothyroxine, they would more likely experience heat intolerance due to increased metabolic activity.

Choice C reason: Restlessness is a symptom of hyperthyroidism, which can occur if a client is taking too much levothyroxine. Excess thyroid hormone can lead to increased nervous system activity, causing symptoms such as restlessness, anxiety, and tremors.

Choice D reason: Decreased appetite is more commonly associated with hypothyroidism. In contrast, hyperthyroidism, which can result from taking too much levothyroxine, often leads to an increased appetite.
