The nurse is preparing a 50 mL dose of 50% dextrose IV for a patient with insulin shock. What is the appropriate method for administering the medication?

Mix the dextrose in a 50 mL piggyback for a total volume of 100 mL.

Dilute the dextrose in one liter of 0.9% normal saline solution.

Request the pharmacist to add the dextrose to a total parenteral nutrition (TPN) solution.

Administer the undiluted dextrose slowly through the currently infusing IV. .

Answer and Explanation

The Correct Answer is D

Choice A rationale
Mixing the dextrose in a 50 mL piggyback for a total volume of 100 mL is not the appropriate method for administering the medication. This would dilute the dextrose, reducing its concentration and potentially making it less effective.
Choice B rationale
Diluting the dextrose in one liter of 0.9% normal saline solution is not the appropriate method for administering the medication. This would significantly dilute the dextrose, reducing its concentration and potentially making it less effective.
Choice C rationale
Requesting the pharmacist to add the dextrose to a total parenteral nutrition (TPN) solution is not the appropriate method for administering the medication. While dextrose is often a component of TPN solutions, in this case, the patient requires a concentrated dose of dextrose to treat insulin shock.

Choice D rationale
This is the correct answer. Administering the undiluted dextrose slowly through the currently infusing IV is the appropriate method for administering the medication. This allows for the rapid administration of a concentrated dose of glucose, which is necessary to quickly raise the patient’s blood glucose level in the case of insulin shock.

Correct Answer is B

Explanation

Choice A rationale
The absence of coarse crackles is not necessarily an indication that chest physiotherapy (CPT) has been effective for a client with chronic obstructive pulmonary disease (COPD). Coarse crackles are often heard in conditions where there is fluid in the airways, such as pneumonia or heart failure. While their absence might indicate that there is no fluid in the airways, it does not necessarily mean that secretions have been effectively mobilized.
Choice B rationale
An increase in breath sounds is a good indication that chest physiotherapy (CPT) has been effective for a client with COPD3. CPT is a group of therapies designed to improve respiratory efficiency, promote expansion of the lungs, strengthen respiratory muscles, and eliminate secretions from the respiratory system. When these secretions are effectively mobilized and removed, breath sounds can become clearer and more easily heard.
Choice C rationale

The absence of fine crackles is not necessarily an indication that CPT has been effective for a client with COPD. Fine crackles are often heard in conditions where there is fluid in the airways or alveoli, such as pneumonia or heart failure. While their absence might indicate that there is no fluid in the airways or alveoli, it does not necessarily mean that secretions have been effectively mobilized.
Choice D rationale
An increase in respiratory rate is not necessarily an indication that CPT has been effective for a client with COPD. In fact, an increased respiratory rate could indicate respiratory distress, which could suggest that the therapy has not been effective or that the client’s condition has worsened.

Correct Answer is ["1.8"]

Explanation

The client weighs 132 pounds. To convert pounds to kilograms, divide the weight in pounds by

2.2. So, the client’s weight in kilograms is: Step 1: 132 pounds ÷ 2.2 = 60 kg The prescription for dantrolene is 1.5 mg/kg. To find out how many milligrams the client should receive, multiply the client’s weight in kilograms by the dosage in mg/kg: Step 2: 60 kg × 1.5 mg/kg = 90 mg The vial is reconstituted to yield a concentration of 50 mg/mL. To find out how many mL the nurse should administer, divide the total dosage in milligrams by the concentration in mg/mL: Step 3: 90 mg ÷ 50 mg/mL = 1.8 mL So, the nurse should administer 1.8 mL of dantrolene.
