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 D

Explanation

Choice A rationale

Testing the stool for occult blood is not typically necessary for a client taking an antibiotic that causes diarrhea. While antibiotics can cause changes in the gastrointestinal tract, they do not typically cause gastrointestinal bleeding.

Choice B rationale

Increasing roughage in the diet can help bulk up the stool and may help alleviate some cases of diarrhea. However, it’s not the primary recommendation for a client taking an antibiotic that causes diarrhea.

Choice C rationale

Requesting the physician for a different antibiotic if diarrhea persists can be an appropriate action. However, this is typically recommended after other strategies, such as adding probiotics to the diet, have been tried.

Choice D rationale

Adding yogurt to the diet is often recommended for clients taking an antibiotic that causes diarrhea. Yogurt contains probiotics, which can help restore the balance of good bacteria in the gut and alleviate diarrhea.

A. Increase intake of proteins, take vitamin C and zinc B. Use care when walking to avoid bumping your limb C. Cleanse the ulcer with soap and water D. Apply cortisone cream to decrease itching E. Put on compression stockings before getting out of bed

Correct Answer is ["A","B","E"]

Explanation

Choice A rationale

Proteins, vitamin C, and zinc are essential for wound healing. Proteins are the building blocks for body tissue, and zinc plays a role in protein synthesis. Vitamin C is needed for the formation of collagen, a protein used to make skin, scar tissue, and blood vessels.

Choice B rationale

Care should be taken when walking to avoid bumping the limb. Any trauma to the affected limb could potentially worsen the condition or delay healing.

Choice C rationale

Cleaning the ulcer with soap and water may not be the best option. Soap can be irritating to the skin and may delay healing. Instead, the ulcer should be cleaned as per healthcare provider’s instructions.

Choice D rationale

Cortisone cream is not typically used for venous stasis ulcers. It can thin the skin and delay healing.

Choice E rationale

Compression stockings are often recommended for patients with post-thrombotic syndrome. They can help reduce swelling and improve blood flow, which can promote healing of the venous stasis ulcer.
