The healthcare provider prescribes enoxaparin sodium 80 mg SUBQ twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, "enox“parin 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.)

Answer and Explanation

The Correct Answer is ["0.8"]

The nurse should administer 0.8 mL of the enoxaparin sodium injection.

Here's th’ breakdown of the calculation:

Prescribed dose: 80 mg

Available medication: 60 mg/0.6 mL

The nurse needs to determine the volume of the available medication that delivers the prescribed dose of 80 mg. We can set up a proportion to find the desired volume (x):

Prescribed dose (mg) : Desired volume (mL) = Concentration (mg/mL) : Available volume (mL)

Plugging in the values:

80 mg : x mL = 60 mg/0.6 mL : 0.6 mL

To isolate x (desired volume), we can cross-multiply:

x mL x (60 mg/0.6 mL) = 80 mg x 0.6 mL

Simplifying the equation

0.6x mL = 48 mg

To find x (desired volume), we can divide both sides by 0.6 mL:

x mL = (48 mg) / (0.6 mL/mL) // Cancel out units (mg/mL)

x = 80 mL

However, the answer needs to be rounded to the nearest tenth since medication dosages are measured precisely.

Therefore, the nurse should administer 0.8 mL of the enoxaparin sodium injection.

Correct Answer is C

Explanation

A) Intolerance to cold: Intolerance to cold is a common symptom of hypothyroidism, not a sign of taking too much levothyroxine sodium. Therefore, this symptom would not indicate an overdose of the medication.

B) Constipation: Constipation can be a symptom of hypothyroidism, and it may improve with appropriate thyroid hormone replacement therapy. It is not typically associated with taking too much levothyroxine sodium.

C) Restlessness: This is the correct answer. Restlessness, anxiety, nervousness, or feeling jittery are symptoms of hyperthyroidism, which can occur if the client is taking too much levothyroxine sodium. If the dose of levothyroxine is too high, it can lead to hyperthyroid symptoms, even though the medication is intended to treat hypothyroidism.

D) Decreased appetite: Decreased appetite is not a typical symptom of taking too much levothyroxine sodium. In fact, weight loss is more commonly associated with hyperthyroidism, which can occur if the dose of levothyroxine is too high. However, decreased appetite alone may not specifically indicate an overdose of levothyroxine.

A. Recent oral intake. B. Trouble sleeping. C. Unexplained weight loss. D. Difficulty with urination.

Correct Answer is A

Explanation

A) Recent oral intake: This information is important because pyridostigmine is typically administered orally and can interact with food, affecting its absorption. It is essential to ensure that the client has recently eaten or will eat soon to minimize gastrointestinal side effects and optimize medication absorption.

B) Trouble sleeping: While sleep disturbances can be a concern, particularly if they worsen with medication use, it may not be the most critical information to obtain before administering pyridostigmine. However, if the client experiences worsening sleep disturbances after starting the medication, it should be reported to the healthcare provider.

C) Unexplained weight loss: While weight loss can be a symptom of myasthenia gravis, it may not be directly related to the administration of pyridostigmine. However, if the client experiences significant weight loss or other unexplained symptoms, further assessment and evaluation may be necessary.

D) Difficulty with urination: Pyridostigmine can affect bladder function and may exacerbate urinary retention, especially in clients with myasthenia gravis. However, obtaining information about the client's recent oral intake is more crucial to ensure optimal medication absorption and minimize gastrointestinal side effects. Difficulty with urination should still be monitored, but it may not be the most immediate concern before administering the medication.
