Upon auscultating a client’s lungs, the nurse identifies crackles in the left posterior base. What action should the nurse take?

Prepare to administer antibiotics.

Instruct the client to limit fluid intake to less than 2,000 m/day.

Initiate bedrest in semi-Fowler’s position.

Repeat the auscultation after asking the client to breathe deeply and cough.

Answer and Explanation

The Correct Answer is D

Choice A rationale
While antibiotics are used to treat bacterial infections, crackles in the lungs can be a sign of various conditions, not just bacterial infections. Therefore, administering antibiotics is not the appropriate action based solely on the finding of crackles.
Choice B rationale

Limiting fluid intake can be beneficial for clients with certain conditions such as heart failure, but it is not the appropriate action based solely on the finding of crackles.
Choice C rationale
Initiating bedrest in semi-Fowler’s position can help improve lung expansion and ease breathing in clients with certain respiratory conditions. However, it is not the appropriate action based solely on the finding of crackles.
Choice D rationale
Crackles can sometimes be cleared by deep breathing and coughing. Repeating the auscultation after asking the client to breathe deeply and cough can help the nurse determine if the crackles are transient (cleared by coughing) or persistent.

Correct Answer is D

Explanation

Choice A rationale
Pursed-lip breathing can help improve oxygenation and reduce shortness of breath in clients with COPD. However, it is not the priority action when a client reports difficulty breathing.
Choice B rationale
Increasing the oxygen flow rate without a physician’s order can lead to oxygen toxicity or suppress the respiratory drive in clients with COPD. Therefore, this is not the priority action.
Choice C rationale
Coughing and expectorating secretions can help clear the airways, but it is not the priority action when a client reports difficulty breathing.

Choice D rationale
Evaluating the client’s respiratory status is the priority action. The nurse should assess the client’s breath sounds, respiratory rate, use of accessory muscles, and oxygen saturation to determine the severity of the client’s difficulty breathing and guide further interventions.

A. 4 mL B. 5 mL C. 6 mL D. 7 mL

Correct Answer is C

Explanation

Step 1 is to determine how many mL to administer. The client needs 300 mg of amoxicillin and the available medication is 250 mg/5 mL. So, the calculation is (300 mg ÷ 250 mg/mL) × 5 mL.
Step 2 is to perform the calculation. The result is 6 mL.
