A nurse is preparing to administer subcutaneous enoxaparin 40 mg using a prefilled syringe of enoxaparin 40 mg/0.4 ml to an adult client following hip arthroplasty.
Which of the following actions should the nurse plan to take?
Aspirate carefully after inserting the needle into the client’s skin.
Administer the injection in the client’s thigh.
Insert the needle at 90 degrees.
Expel the air bubble from the prefilled syringe before injecting.
The Correct Answer is C
This is because enoxaparin is administered subcutaneously, which means under the skin, and the needle should be inserted fully into the skin to ensure proper delivery of the drug.
Choice A is wrong because aspirating (pulling back on the plunger) after inserting the needle is not recommended for subcutaneous injections of enoxaparin, as it may increase the risk of bleeding or bruising.
Choice B is wrong because administering the injection in the client’s thigh is not the preferred site for enoxaparin. The preferred site is the abdomen, at least 2 inches away from the navel, as it has more fatty tissue and less blood vessels than other areas.
Choice D is wrong because expelling the air bubble from the prefilled syringe is not necessary for enoxaparin. The air bubble helps to ensure that the entire dose of enoxaparin is injected and prevents blood from entering the syringe.
Normal ranges for enoxaparin dosage depend on the indication and the patient’s weight, but for prophylaxis of deep vein thrombosis after hip arthroplasty, the usual dose is 40 mg once a day for 3 weeks.
The prefilled syringe of enoxaparin 40 mg/0.4 ml contains the correct dose for this indication.

Correct Answer is B
Explanation
Lifestyle is the greatest contributing factor that can lead to many diseases, especially noncommunicable diseases (NCDs) such as cardiovascular diseases, cancers, chronic respiratory diseases and diabetes.According to the World Health Organization (WHO), NCDs are responsible for 74% of all deaths worldwide, and they share four major risk factors: tobacco use, physical inactivity, the harmful use of alcohol and unhealthy diets.These modifiable behaviours increase the risk of metabolic risk factors such as raised blood pressure, increased blood glucose, elevated blood lipids and obesity, which can lead to NCDs.
Choice A is wrong because trauma is not a factor that can lead to many diseases, but rather a result of injuries or accidents that damage the body.Trauma can cause acute or chronic conditions, such as infections, bleeding, fractures, organ failure or post-traumatic stress disorder, but it is not a common cause of NCDs.
Choice C is wrong because congenital means present at birth or inherited.
Congenital diseases are caused by genetic mutations or environmental factors that affect the development of the fetus.
Some examples of congenital diseases are Down syndrome, cystic fibrosis, congenital heart defects and spina bifida.
Congenital diseases are not the greatest contributing factor to many diseases because they are relatively rare and often detected early.
Choice D is wrong because genetics refers to the inherited traits from parents that influence the risk of developing certain diseases.
Genetics can play a role in some NCDs, such as cancers, diabetes and some cardiovascular diseases, but it is not the only or the most important factor.
Genetics interacts with environmental and lifestyle factors to determine the likelihood of developing a disease.
Therefore, genetics alone cannot lead to many diseases.
Correct Answer is C
Explanation
Positive inotropy and negative chronotropy.Digoxin is a cardiac glycoside that increases the force of the heart contractions (positive inotropy) and slows down the heart rate (negative chronotropy).
Choice A is wrong because positive chronotropy means increasing the heart rate, which is the opposite of what digoxin does.
Choice B is wrong because negative inotropy means decreasing the force of the heart contractions, which is also the opposite of what digoxin does.
Choice D is wrong because positive chronotropy means increasing the heart rate, which is not what digoxin does.
Digoxin is used to treat heart failure and atrial fibrillation, a type of irregular heartbeat.It has a narrow therapeutic window, meaning that the dose must be carefully adjusted to avoid toxicity or ineffectiveness.
