The nurse is teaching an overweight patient to administer subcutaneous heparin. Which statement by the patient indicates understanding of the teaching?
"I should insert the needle and inject the medication without aspirating for blood."
"I should put firm pressure on the injection site to decrease the risk for bleeding."
"I will insert the needle at a 10-degree angle when injecting."
"The subcutaneous route is used because absorption is faster this way."
The Correct Answer is A
A. When administering subcutaneous heparin, aspiration should be avoided because it can cause tissue damage and increase the risk of hematoma formation. This statement correctly reflects safe administration technique.
B. Firm pressure on the injection site is not recommended after heparin administration because it can increase the risk of bruising and bleeding. Instead, gentle pressure should be applied if necessary.
C. Subcutaneous injections should be given at a 45- to 90-degree angle, depending on the patient’s body mass. A 10-degree angle is too shallow and may result in improper medication delivery.
D. The subcutaneous route does not provide faster absorption than other routes such as intravenous or intramuscular. Instead, it allows for slow, steady absorption, which is desirable for anticoagulants like heparin.

Correct Answer is D
Explanation
a) Encouraging self-application is beneficial in some cases, but it is not always appropriate. The nurse must ensure the medication is applied correctly and safely, especially if the patient has mobility or cognitive impairments.
b) Wearing treatment gloves is important when handling certain medications, but it is not required for all topical applications. Some medications, such as nitroglycerin ointment, require gloves to prevent nurse exposure, but others do not.
c) Changing gloves between skin preparation and medication application is not a universal requirement. In most cases, the same pair of gloves can be used unless contamination occurs.
d) Performing effective hand hygiene before and after applying the medication is the most essential action to prevent infection and cross-contamination.
Correct Answer is D
Explanation
a) Children can participate in clinical drug trials when appropriate consent is obtained from parents or guardians and when the study complies with ethical guidelines. They are not excluded from trials entirely because they cannot give consent.
b) Children can participate in various types of clinical studies, not just quasi-experimental ones, as long as the study follows ethical and legal guidelines for pediatric research.
c) Data from adult clinical trials cannot always be directly applied to children due to physiological differences. Pediatric drug testing is necessary to ensure drugs are both safe and effective for children.
d) Federal law mandates that drugs for children undergo testing in pediatric populations. This is to ensure that drugs are safe and effective for children, as they may respond differently than adults to medications.
