A client with a history of angina reports the onset of chest pain. The nurse determines that the heart rate is 104 beats/minute and the blood pressure is 138/86 mm Hg. A transdermal nitroglycerin patch was applied 30 minutes ago to the right upper chest. Which action should the nurse take?

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.

A) Feverfew may interact with aspirin or nonsteroidal anti-inflammatory drugs: This information is crucial to include in the teaching plan because feverfew has been reported to interact with medications such as aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs), potentially increasing the risk of bleeding. Clients need to be aware of potential drug interactions to prevent adverse effects and ensure safe use of feverfew.

B) Those with allergies to chamomile, ragweed, or yarrow should not take feverfew: While this is important information to consider, it may not be as immediately relevant to the client's current situation of experiencing fewer headaches with feverfew use. However, it is still important to assess for allergies and sensitivities to prevent allergic reactions.

C) Increased anxiety and nervousness have been reported by those taking feverfew: Although this is a potential side effect of feverfew, it may not be the most important information to include in the teaching plan for a client who is experiencing fewer headaches with feverfew use. The focus should be on the client's positive response to the herbal remedy and potential interactions with other medications.

D) Abdominal pain, gas, nausea, vomiting, and diarrhea can occur when taking feverfew: While this is important information regarding potential side effects of feverfew, it may not be as immediately relevant to the client's current situation of experiencing fewer headaches with feverfew use. However, clients should be informed about possible adverse effects to monitor for and report to their healthcare provider if they occur.
