A client with multiple sclerosis (MS) is receiving interferon beta-1b 0.1875 mg subcutaneously every other day. The nurse reconstitutes the vial by slowly injecting 1.2 mL of diluent into the interferon vial for a reconstituted solution of 0.25 mg/1 mL. How many mL should the nurse administer?

(Enter numeric value only. If rounding is required, round to the nearest hundredth.)

Answer and Explanation

The Correct Answer is ["0.75"]

Calculate the volume of the reconstituted solution that contains the prescribed dose of 0.1875 mg. Since the reconstituted solution has a concentration of 0.25 mg per 1 mL, we can set up a proportion to find the answer: (0.1875 mg / X mL) = (0.25 mg / 1 mL).

Solving for X gives us X = (0.1875 mg * 1 mL) / 0.25 mg, which equals 0.75 mL.

Therefore, the nurse should administer 0.75 mL of the reconstituted solution.

Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"B"},"E":{"answers":"A"}}

Explanation

Correct choices are;

A.I should have taken an extra dose of fluticasone-salmeterol -No Understanding
Explanation: Fluticasone/salmeterol is a long-acting inhaler used for maintenance therapy in asthma. It is not meant to be used as a rescue medication for acute symptoms or exacerbations. Therefore, taking an extra dose in response to symptoms would not be appropriate.

B. I should have taken some allergy medications before going on the hike -Understanding
Explanation: Allergy medications, such as antihistamines or nasal sprays, can help reduce allergic triggers that can exacerbate asthma symptoms. Taking these medications before exposure to known triggers (like allergens during a hike) can help prevent an asthma exacerbation.

C. I have been very stressed out lately and should work on stress management -Understanding
Explanation: Stress is a known trigger for asthma exacerbations. Managing stress through techniques such as relaxation exercises, mindfulness, or therapy can help reduce the likelihood of triggering asthma symptoms.

D. I should have eaten a snack halfway through the hike - No Understanding
Explanation: While maintaining good nutrition and hydration is important for overall health, eating a snack would not necessarily prevent an asthma exacerbation unless the snack contained medications or substances that specifically manage asthma symptoms.

E. My friend smoked cigarettes during the hike - Understanding
Explanation: Secondhand smoke is a common trigger for asthma exacerbations. Being exposed to cigarette smoke can irritate the airways and worsen asthma symptoms.

A. Finish the procedure. B. Close the room door. C. Call for an assistant. D. Respond to the code.

Correct Answer is A

Explanation

Rationale

A. Finish the procedure is rooted in the fundamental nursing principle of patient abandonment and the ABC (Airway, Breathing, Circulation) priority framework.

B. Closing the room door is not a priority action during a code blue. The immediate focus should be on responding to the emergency and providing assistance as needed.

C. If additional help is needed to assist with the tracheostomy care procedure, calling for an assistant could be appropriate under normal circumstances. However, during a code blue, the primary responsibility is to respond to the emergency immediately.

D. You cannot leave one life-threatening situation (a compromised airway) to attend another, especially when a specialized team is already being activated for the code.
