A nurse is reviewing the medical record of a client who has pneumonia. Which of the following serum laboratory values should the nurse expect?

WBC count 15,000/mm3

Sodium 130 mg/dL

BUN 8 mg/dL

Hematocrit 35%

Answer and Explanation

The Correct Answer is A

A high white blood cell (WBC) count is a common sign of infection and inflammation, such as pneumonia. The normal range of WBC count is 4,500 to 11,000/mm3 . Sodium, blood urea nitrogen (BUN), and hematocrit are not directly related to pneumonia and may vary depending on other factors such as hydration status, renal function, and blood loss.

Correct Answer is B

Explanation

The client should expect less than 25 mL of secretions per day in the drainage devices before they are removed, usually within 7 to 10 days after surgery. This indicates that the wound is healing and there is no excessive fluid accumulation in the surgical site. The other statements are incorrect and indicate a need for further teaching. The client should not wait 2 months before additional saline can be added to the breast expander, as this may delay the reconstruction process and increase the risk of infection or contracture.

The client should keep the left arm elevated on a pillow and avoid flexing it at the elbow, as this may impair lymphatic drainage and cause edema or pain. The client should perform gentle range-of-motion exercises with the left arm and avoid lifting heavy objects such as a 15-pound weight, as this may strain the incision or cause bleeding.

A. Scaly lesion with a crusted appearance B. Raised lesion with a rolled border C. Reddened lesion with dilated blood vessels D. Flat lesion with irregular borders

Correct Answer is D

Explanation

A flat lesion with irregular borders is one of the signs of melanoma, a type of skin cancer that arises from melanocytes, the cells that produce pigment. Other signs of melanoma include asymmetry, color variation, diameter greater than 6 mm, and evolution or change over time. The other options are more characteristic of other types of skin cancer or benign lesions.
