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 C

Explanation

Choice A rationale
Antimicrobial dressings are typically used for wounds that are infected or at high risk of infection. A stage I pressure ulcer, which involves intact skin with non-blanchable redness, would not typically require an antimicrobial dressing.
Choice B rationale
Wet-to-dry dressings are used for mechanical debridement of wounds with necrotic tissue. A stage I pressure ulcer does not involve necrotic tissue, so this type of dressing would not be appropriate.
Choice C rationale
Transparent dressings are often used for stage I pressure ulcers. They provide a protective layer over the wound, promoting a moist environment and facilitating the healing process.
Choice D rationale

Dry, sterile dressings are typically used for wounds that need to be kept dry. A stage I pressure ulcer benefits from a moist healing environment, which can be provided by a transparent dressing.

A. 1 tablet B. 2 tablets C. 3 tablets D. 4 tablets

Correct Answer is B

Explanation

Step 1 is to determine how many tablets to administer. The client needs 650 mg of aspirin and each tablet contains 325 mg. So, the calculation is 650 mg ÷ 325 mg/tablet.
Step 2 is to perform the calculation. The result is 2 tablets.
