The nurse is to administer enoxaparin 40 mg subcutaneously to the patient. Which technique is correct?
The nurse aspirates immediately prior to injecting the medication.
The nurse gently massages the injection site immediately afterward.
The nurse draws up the medication into a 1-mL syringe with a 32-gauge needle.
The nurse injects the medication into the soft tissue of the patient’s abdomen.
The Correct Answer is D
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.

Correct Answer is C
Explanation
Rationale for Choice A:
Incorrect. While the patient is experiencing an allergic reaction, it is not moderate. The presence of difficulty breathing and a drop in blood pressure are signs of a severe, life-threatening anaphylactic reaction.
Anaphylaxis is a severe, rapid-onset allergic reaction that can lead to death if not treated promptly. It typically involves multiple body systems, including the skin, respiratory system, cardiovascular system, and gastrointestinal system.
Moderate allergic reactions typically present with localized symptoms such as hives, itching, and redness. They do not typically involve respiratory or cardiovascular compromise.
Rationale for Choice B:
Incorrect. The patient's symptoms are not consistent with food poisoning. Food poisoning typically causes gastrointestinal symptoms such as nausea, vomiting, diarrhea, and abdominal cramps. It does not typically cause hives, difficulty breathing, or a drop in blood pressure.
The timing of the symptoms, occurring 2 hours after receiving an antibiotic, strongly suggests an allergic reaction to the medication.
Rationale for Choice C:
Correct. The patient's symptoms are consistent with anaphylaxis, a severe allergic reaction that requires immediate emergency treatment.
Key features of anaphylaxis include:
Skin involvement (hives, itching, flushing, swelling)
Respiratory distress (difficulty breathing, wheezing, tightness in the chest) Cardiovascular compromise (drop in blood pressure, lightheadedness, fainting) Gastrointestinal symptoms (nausea, vomiting, diarrhea)
Swelling of the tongue or throat
Rationale for Choice D:
Incorrect. The patient's reaction is not mild and cannot be treated with an antihistamine alone. Antihistamines are effective for mild allergic reactions, but they are not sufficient to treat anaphylaxis.
Anaphylaxis requires immediate treatment with epinephrine, which is a life-saving medication that can reverse the effects of the allergic reaction.
Correct Answer is A
Explanation
Choice A rationale:
Hemorrhoids are swollen veins in the anus and rectum that can cause pain, itching, and bleeding. Sitz baths are a common and effective treatment for hemorrhoids because they can help to:
Reduce inflammation and pain Promote healing
Relax the anal sphincter muscles Cleanse the anal area
Warm water helps to increase blood flow to the area, which can help to reduce swelling and inflammation. The water also helps to soothe and cleanse the irritated tissues.
Sitz baths are typically taken for 10-15 minutes at a time, several times a day. They can be taken in a bathtub or a special sitz bath basin that fits over a toilet seat.
Choice B rationale:
A fractured right arm would not benefit from a sitz bath. Sitz baths are specifically for treating the anal and rectal area.
Choice C rationale:
An abscessed tooth would not benefit from a sitz bath. Sitz baths are specifically for treating the anal and rectal area.
Choice D rationale:
Painful back muscle spasms would not benefit from a sitz bath. Sitz baths are specifically for treating the anal and rectal area.
