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.)

Answer and Explanation

The Correct Answer is ["0.8"]

Calculation Steps

Step 1: Identify the concentration of the medication in the syringe.

The syringe is labeled “Enoxaparin sodium injection, USP 60 mg/0.6 mL.”

Step 2: Calculate the amount of medication per mL.

60 mg ÷ 0.6 mL = 100 mg/mL

Result = 100 mg/mL

Step 3: Determine the prescribed dose.

The prescribed dose is 80 mg.

Step 4: Calculate the volume to administer.

80 mg ÷ 100 mg/mL = 0.8 mL

Result = 0.8 mL

Therefore, the nurse should administer 0.8 mL.

Correct Answer is B

Explanation

Choice A reason: Taking tamsulosin early in the day is not necessary. Tamsulosin should be taken approximately 30 minutes after the same meal each day to ensure consistent absorption and effectiveness1. The timing of the dose is less critical than ensuring it is taken after the same meal daily.

Choice B reason: Tamsulosin can cause orthostatic hypotension, which is a sudden drop in blood pressure when standing up from a sitting or lying position. This can lead to dizziness or fainting. Therefore, it is crucial to instruct patients to stand and sit up slowly to prevent falls and injuries.

Choice C reason: Reducing daily fluid intake is not recommended for patients taking tamsulosin. Adequate hydration is important for overall health and can help manage urinary symptoms associated with BPH. There is no evidence suggesting that fluid restriction improves the effectiveness of tamsulosin.

Choice D reason: Tamsulosin should be taken daily, not on a twice-a-week dosing schedule. Consistent daily dosing is necessary to maintain stable blood levels of the medication and ensure its effectiveness in managing urinary retention due to BPH.

A. Irritable bowel syndrome. B. Coronary artery disease. C. Seasonal allergic rhinitis. D. Type 2 diabetes mellitus.

Correct Answer is B

Explanation

Choice A reason:

Irritable bowel syndrome (IBS) is not a primary concern when administering sumatriptan succinate. While IBS can cause significant discomfort and affect the quality of life, it does not pose a direct contraindication to the use of sumatriptan. Sumatriptan is primarily metabolized in the liver and excreted by the kidneys, and its use is not significantly impacted by gastrointestinal conditions like IBS1.

Choice B reason:

Coronary artery disease (CAD) is a critical consideration before administering sumatriptan succinate. Sumatriptan is a selective serotonin receptor agonist that causes vasoconstriction of cranial blood vessels to relieve migraine symptoms. However, it can also cause vasoconstriction in coronary arteries, which can be dangerous for clients with CAD. This can lead to serious cardiovascular events such as myocardial infarction or angina. Therefore, it is essential to assess for any history of CAD or other significant cardiovascular conditions before administering this medication.

Choice C reason:

Seasonal allergic rhinitis is not a significant concern when administering sumatriptan succinate. While allergic rhinitis can cause symptoms such as nasal congestion, sneezing, and itching, it does not interact with the pharmacological action of sumatriptan. Therefore, it is not a contraindication for the use of this medication.

Choice D reason:

Type 2 diabetes mellitus is not a primary concern when administering sumatriptan succinate. Although diabetes can increase the risk of cardiovascular disease, the presence of diabetes alone does not contraindicate the use of sumatriptan. However, it is important to consider the overall cardiovascular risk profile of the client, including any complications related to diabetes.
