The nurse administers a medication to the patient.
Which symptoms indicate that the patient is having an allergic reaction rather than a side effect?

Choice A rationale:

Aspirating prior to injecting enoxaparin is not recommended.

Aspiration was once a common practice to check if a needle had entered a blood vessel.

However, research has shown that aspiration is not necessary for subcutaneous injections and may even be harmful. It can cause pain, bruising, and hematoma formation.

Additionally, aspirating can increase the risk of needlestick injuries.

For these reasons, aspiration is no longer recommended for subcutaneous injections of enoxaparin or other anticoagulants.

Choice B rationale:

Massaging the injection site after administering enoxaparin is not recommended. Massaging can increase the risk of bruising and hematoma formation.

It can also cause the medication to be absorbed too quickly, which can increase the risk of bleeding.

The best practice is to apply gentle pressure to the injection site with a dry gauze pad for a few seconds after the injection. This will help to prevent bleeding and bruising.

Choice C rationale:

The size of the syringe and needle used to administer enoxaparin is not specified in the question. However, a 1-mL syringe with a 32-gauge needle is a common choice for subcutaneous injections.

This size syringe is small enough to be easy to handle, and the 32-gauge needle is thin enough to minimize discomfort.

Choice D rationale:

The abdomen is the preferred site for subcutaneous injections of enoxaparin.

The abdomen has a large surface area of soft tissue, which makes it easy to inject the medication.

The abdomen is also relatively free of blood vessels and nerves, which reduces the risk of bruising, bleeding, and pain. Other potential injection sites for enoxaparin include the upper arms, thighs, and buttocks.

However, the abdomen is generally the preferred site.

Choice A rationale:

Splinting the incision when coughing helps to minimize pain and discomfort, which can encourage deeper breathing and coughing. This is essential because deep breathing and coughing help to clear secretions from the lungs and prevent atelectasis (collapse of lung tissue).

Steps for splinting the incision:

Place a pillow or folded towel over the incision site.

Instruct the patient to apply gentle pressure to the pillow or towel with their hands when coughing or deep breathing. Encourage the patient to relax their abdominal muscles during coughing and deep breathing exercises.

Choice B rationale:

Sitting up in a chair and ambulating promote lung expansion and help to mobilize secretions. This is because gravity assists in moving secretions from the smaller airways into the larger airways, where they can be more easily coughed up.

Additional benefits of sitting up and ambulating: Improved circulation

Decreased risk of pneumonia Enhanced recovery from surgery Choice C rationale:

Using an incentive spirometer hourly helps to increase lung capacity and prevent atelectasis. The device encourages the patient to take slow, deep breaths, which helps to inflate the alveoli (air sacs) in the lungs.

Instructions for using an incentive spirometer:

Sit upright in a chair or bed.

Place the mouthpiece of the spirometer in your mouth and seal your lips around it.

Inhale slowly and deeply through the mouthpiece, aiming to raise the piston inside the device as high as possible. Hold your breath for 3-5 seconds.

Exhale slowly and completely through the mouthpiece.

Repeat the process 10-15 times per hour, or as instructed by your healthcare provider.
