A nurse is preparing to administer enoxaparin to a client.
Which of the following actions should the nurse plan to take?
Aspirate for a blood return before depressing the plunger.
Administer the medication 2.54 cm (1 in) from the umbilicus.
The nurse should not expel the air bubble in the prefilled syringe.
Insert the needle at a 45 degree angle.
The Correct Answer is C
This question tests the safe administration of low-molecular-weight heparin. It requires knowledge of syringe design and subcutaneous injection technique, specifically the necessity of maintaining the air bubble to ensure the full dose of medication is delivered and to prevent drug loss in the needle hub.
Choice A rationale
Enoxaparin is administered via subcutaneous injection. Aspirating before depressing the plunger is not indicated for this route, as there is no significant risk of hitting a large blood vessel that would require this maneuver for safety.
Choice B rationale
The injection site for enoxaparin should be at least 5 cm (2 inches) away from the umbilicus. Injecting too close to the navel increases the risk of local bruising and hematoma formation due to the high vascularity of that area.
Choice C rationale
Prefilled syringes for enoxaparin are designed with an air bubble to ensure the entire prescribed dose is delivered. Expelling this bubble can lead to an incomplete dose, which is clinically significant when administering anticoagulants for therapeutic, weight-based management.
Choice D rationale
Subcutaneous injections are typically administered at a 90 degree angle if enough adipose tissue is grasped to avoid intramuscular injection. Using a 45 degree angle is generally reserved for patients with very little subcutaneous tissue to ensure proper delivery.

Correct Answer is C
Explanation
This question tests understanding of the therapeutic application of ACE inhibitors. It requires identifying the pharmacological effect of lisinopril on the renin-angiotensin-aldosterone system, specifically its role in lowering systemic vascular resistance to manage hypertensive conditions effectively and prevent long-term cardiovascular complications.
Choice A rationale
Lisinopril is an ACE inhibitor used to manage hypertension and heart failure. It has no mechanism of action related to the stabilization of mood or the prevention of bipolar manic episodes, which are managed with mood stabilizers or antipsychotic medications.
Choice B rationale
ACE inhibitors do not have a therapeutic effect on lipid metabolism, such as increasing HDL cholesterol levels. Patients requiring cholesterol management are typically prescribed statins, which specifically target the synthesis of lipids in the liver to improve the cardiovascular profile.
Choice C rationale
Lisinopril blocks the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. By reducing angiotensin II levels, the drug promotes systemic vasodilation, which lowers blood pressure and reduces the workload on the heart, indicating a clear therapeutic effect.
Choice D rationale
ACE inhibitors are not indicated for improving sexual function. In some clinical cases, they have been associated with sexual dysfunction as a side effect. Patients experiencing these issues should consult their provider, as it is not a desired therapeutic outcome.
Correct Answer is ["750"]
Explanation
Step 1 is convert weight in lbs to kg: 55 lbs ÷ 2.2 lbs/kg = 25 kg.
Step 2 is calculate the dose: 30 mcg/kg × 25 kg = 750 mcg. Final calculated answer is 750 mcg.
