A nurse is preparing to administer a heparin infusion of 25,000 units in 250 mL of normal saline at a rate of 1000 units per hour for a client diagnosed with a Deep Vein Thrombosis (DVT). The client’s initial activated partial thromboplastin time (aPTT) value is 35 seconds.

Which laboratory result would indicate that the aPTT is at a therapeutic level?

30 seconds

45 seconds

60 seconds

75 seconds

Answer and Explanation

The Correct Answer is D

Step 1 is to understand the therapeutic range for aPTT when a patient is on heparin therapy. The therapeutic range for aPTT is 1.5 to 2.5 times the normal value. Given that the normal aPTT value is around 30-40 seconds, the therapeutic range would be approximately 45-100 seconds. Therefore, an aPTT value of 75 seconds falls within this therapeutic range, indicating that the heparin therapy is effective.

Correct Answer is C

Explanation

A heart murmur due to mitral valve disease is typically heard loudest over the mitral area, which is located at the fifth intercostal space in the left midclavicular line.

A. Inject the insulin syringe at a 90-degree angle. B. Avoid the deltoid when injecting the insulin. C. Rotate injection sites correctly. D. Massage the injection site.

Correct Answer is C

Explanation

Choice A rationale

Injecting the insulin syringe at a 90-degree angle is a technique used to ensure that the insulin is delivered into the subcutaneous tissue. However, this does not specifically prevent lipodystrophy.

Choice B rationale

Avoiding the deltoid when injecting insulin is not typically a recommendation for preventing lipodystrophy. Insulin is usually injected into the fatty tissue just under the skin in the abdomen, thighs, buttocks, or upper arms.

Choice C rationale

Rotating injection sites correctly is a key strategy for preventing lipodystrophy. Lipodystrophy refers to abnormal changes in the fat tissue under the skin and can be caused by repeatedly injecting insulin into the same spot.

Choice D rationale

Massaging the injection site is not typically recommended as it can cause the insulin to be absorbed too quickly.
