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 B

Explanation

A) Taking ferrous sulfate elixir with a glass of milk is not recommended because milk can interfere with the absorption of iron. Iron absorption is enhanced in an acidic environment, and milk's ca’cium content can inhibit this process.

B) Using a straw to ingest the ferrous sulfate elixir is advisable because it can help minimize contact between the medication and the teeth, reducing the risk of staining. Iron supplements can cause discoloration of the teeth, and using a straw directs the liquid towards the back of the mouth, bypassing the teeth.

C) Swallowing ferrous sulfate elixir undiluted is the usual method of administration; however, doing so may increase the risk of staining the teeth due to direct contact with the oral mucosa and teeth. It is important to follow the healthcare provider's in’tructions regarding dosage and administration.

D) Mixing ferrous sulfate elixir with an antacid is generally not recommended unless specifically directed by the healthcare provider. Antacids containing calcium or magnesium can bind to iron, forming complexes that are poorly absorbed in the gastrointestinal tract, thereby reducing the effectiveness of iron supplementation.

A. Provide information on increasing medication dosage If ketoacidosis occurs. B. Teach the client self-injection skills for daily subcutaneous administration. C. Demonstrate how to select dose based on before meal blood sugar readings. D. Explain to the family how to inject this medication for severe hypoglycemia.

Correct Answer is B

Explanation

A) Provide information on increasing medication dosage if ketoacidosis occurs: While it is important for clients with diabetes to understand the signs and symptoms of diabetic ketoacidosis (DKA) and how to respond, increasing insulin dosage on their own without healthcare provider guidance could be dangerous. Adjusting insulin dosage should always be done under the direction of a healthcare provider.

B) Teach the client self-injection skills for daily subcutaneous administration: Insulin glargine is a long-acting insulin used for basal (background) insulin coverage in clients with diabetes. Teaching the client how to self-administer insulin injections is essential for effective management of diabetes, especially when using long-acting insulin formulations like insulin glargine. Proper injection technique, site rotation, and storage of insulin are important aspects of this teaching.

C) Demonstrate how to select dose based on before meal blood sugar readings: Insulin glargine is typically administered once daily at the same time each day and is not adjusted based on before meal blood sugar readings. Instead, it provides a steady level of insulin over 24 hours to help control blood sugar levels between meals and overnight.

D) Explain to the family how to inject this medication for severe hypoglycemia: Insulin glargine is not used for the treatment of severe hypoglycemia. Instead, it is a long-acting insulin used to maintain basal insulin levels in clients with diabetes. Severe hypoglycemia is treated with fast-acting glucose sources such as oral glucose tablets, gel, or glucagon injections, and the family should be educated on these treatments instead.
