A nurse is caring for a client prescribed drug N 235 mcg PO daily. Available is drug N PO 0.5 mg per 1 scored tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.5"]

Step 1: Convert the prescribed dose from mcg to mg.

235 mcg ÷ 1000 = 0.235 mg

Step 2: Determine the strength of the available tablet.

Available strength = 0.5 mg per tablet

Step 3: Calculate the number of tablets needed.

Number of tablets = 0.235 mg ÷ 0.5 mg/tablet

Step 4: Perform the division.

0.235 ÷ 0.5 = 0.47

Step 5: Round the answer to the nearest tenth.

0.47 rounded to the nearest tenth = 0.5

Correct Answer is ["66.7"]

Explanation

Step 1: Determine the total volume to be administered. Total volume = 1600 mL

Step 2: Determine the total time in hours. Total time = 24 hours

Step 3: Calculate the rate in mL/hr. Rate = Total volume ÷ Total time Rate = 1600 mL ÷ 24 hours Rate = 66.6667 mL/hr

Step 4: Round to the nearest tenth. Rounded rate = 66.7 mL/hr

The nurse should set the IV pump to deliver 66.7 mL/hr.

A. Administer oxygen per prescriber’s order to keep SpO2 greater than 96%. B. Place patient in Sims position to assist with airway clearance. C. Assess client use of a peak expiratory flow rate meter. D. Assist with coughing and deep breathing at least every 2 hours while awake.

Correct Answer is D

Explanation

Choice A reason:

Administering oxygen per the prescriber’s order to keep SpO2 greater than 96% is not typically recommended for clients with chronic bronchitis. High levels of oxygen can suppress the respiratory drive in clients with chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis. The target SpO2 for these clients is usually between 88% and 92%.

Choice B reason:

Placing the patient in the Sims position is not the most effective position for airway clearance. The Fowler’s or semi-Fowler’s position is generally preferred as it promotes better lung expansion and facilitates easier breathing.

Choice C reason:

Assessing the client’s use of a peak expiratory flow rate meter is important for monitoring the severity of bronchospasm and airflow obstruction. However, it is not a direct intervention for improving gas exchange.

Choice D reason:

Assisting with coughing and deep breathing at least every 2 hours while awake is an effective intervention for clients with chronic bronchitis. This helps to mobilize secretions, improve ventilation, and enhance gas exchange. Regular coughing and deep breathing exercises can prevent atelectasis and reduce the risk of respiratory infections.
