A nurse is caring for a client who develops a sudden onset of dyspnea. Which of the following findings should the nurse expect if the client has a pulmonary embolus?
Expiratory rhonchi.
Petechiae over the lower extremities.
Hemoptysis.
Flattened neck veins.
The Correct Answer is C
Choice A rationale:
Expiratory rhonchi are typically associated with conditions such as chronic bronchitis or asthma but are not specific to pulmonary embolism.
Choice B rationale:
Petechiae over the lower extremities is not a characteristic finding in pulmonary embolism. Petechiae are tiny red or purple spots that appear due to bleeding under the skin and may be associated with other conditions like thrombocytopenia.
Choice C rationale:
The correct choice. Hemoptysis, which refers to coughing up blood, is a concerning finding in pulmonary embolism. It occurs due to the obstruction of blood flow in the pulmonary vasculature, leading to blood leaking into the lungs.
Choice D rationale:
Flattened neck veins are more likely to be observed in conditions associated with decreased venous return to the heart, such as hypovolemia or cardiac tamponade, and are not directly related to pulmonary embolism.

Correct Answer is ["A","C","E"]
Explanation
Choice A rationale:
An elevated white blood cell (WBC) count is an expected manifestation in a client with suspected appendicitis. Inflammation in the appendix leads to an immune response, causing an increase in WBC count.
Choice B rationale:
Elevated amylase level is not typically associated with appendicitis. Elevated amylase is more commonly seen in pancreatitis, not appendicitis.
Choice C rationale:
Rebound tenderness, which refers to increased pain when pressure is released rather than applied, is a classic symptom of appendicitis. The nurse should expect to find rebound tenderness during the abdominal assessment.
Choice D rationale:
Ascites are not a common manifestation of appendicitis. Ascites is the accumulation of fluid in the abdominal cavity and are more commonly seen in liver cirrhosis and certain other conditions, but not in appendicitis.
Choice E rationale:
Anorexia, or loss of appetite, can be seen in clients with appendicitis due to the inflammation and discomfort in the abdominal region.
Correct Answer is A
Explanation
Choice A rationale:
The client's ABG values show a pH of 7.48, PCO2 of 30 mm Hg, HCO3 of 24 mEq/L, and PaO2 of 85 mm Hg. The elevated pH and decreased PCO2 (respiratory component) suggest respiratory alkalosis. Respiratory alkalosis occurs when there is excessive ventilation, leading to a decrease in carbon dioxide levels (hypocapnia) and subsequent alkalosis.
Choice B rationale:
Respiratory acidosis is characterized by an elevated PCO2 and decreased pH. In this case, the client's PCO2 is decreased, indicating respiratory alkalosis rather than respiratory acidosis.
Choice C rationale:
Metabolic alkalosis is characterized by an elevated HCO3 (bicarbonate) level and an increased pH. The client's HCO3 level is within the normal range, making metabolic alkalosis an incorrect identification.
Choice D rationale:
Metabolic acidosis is characterized by a decreased HCO3 level and a decreased pH. The client's HCO3 level is within the normal range, ruling out metabolic acidosis as the acid-base imbalance in this case.
