3. When a patient is ordered to receive a subcutaneous heparin injection, the practical nurse should administer it at which angle?
Subcutaneous injections are given at 45–90 degrees depending on body fat, ensuring the medication is deposited in the subcutaneous tissue rather than muscle or skin.
4. Why is regular risk reassessment important?
Regular risk reassessment is essential because risks are dynamic — new threats emerge, existing risks change in severity, and the effectiveness of controls may vary over time.
5. Which type of muscle tissue is found exclusively in the heart?
Cardiac muscle is involuntary, striated muscle found only in the myocardium; it contracts rhythmically and continuously without fatigue under normal conditions.
