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 WBC count (leukocytosis) indicates an inflammatory response to an infection, such as pneumonia. The nurse should expect to see this value in a client who has pneumonia and monitor the client for signs and symptoms of sepsis or systemic inflammatory response syndrome (SIRS). The other values are within normal or expected ranges for a client who has pneumonia.

Correct Answer is D

Explanation

A hacking cough, especially at night or when lying down, is a common manifestation of left-sided heart failure, as fluid accumulates in the lungs and causes pulmonary congestion and dyspnea. Neck-vein distention and ankle edema are more indicative of right-sided heart failure, as fluid backs up into the systemic circulation and causes peripheral edema and jugular venous pressure elevation. Anorexia may occur in either type of heart failure, but it is not specific to left-sided heart failure.

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.
