A nurse is assigning tasks to an assistive personnel (AP). Which of the following tasks should the nurse assign to the AP?

Rationale:

A. Paradoxical chest movement: Paradoxical chest movement is typically associated with flail chest, where multiple rib fractures cause a segment of the chest wall to move in the opposite direction during breathing. It is not a characteristic finding of tension pneumothorax, which involves intrathoracic pressure buildup rather than rib instability.

B. Bilateral crackles: Bilateral crackles are usually indicative of fluid in the alveoli, such as in pulmonary edema or pneumonia. Tension pneumothorax generally causes decreased or absent breath sounds on the affected side, not crackles, due to lung collapse.

C. Asymmetry of the chest: Tension pneumothorax often causes visible asymmetry of the chest because the affected side may appear distended while the other side may appear sunken. The increased intrathoracic pressure pushes mediastinal structures toward the unaffected side, making chest asymmetry a hallmark sign.

D. Blood-tinged sputum: Blood-tinged sputum is more commonly seen with pulmonary infections, trauma to the airway, or pulmonary embolism. It is not a primary manifestation of tension pneumothorax, which is primarily characterized by respiratory distress and unilateral findings.

Rationale for correct choices

• an endoscopy: The client reports a 3-week history of gnawing, burning epigastric pain that radiates to the back, worsens after meals, and is accompanied by one episode of dark, tarry stool. These symptoms suggest a possible peptic ulcer or gastrointestinal bleeding. An endoscopy is the definitive diagnostic procedure to visualize the gastric mucosa, identify ulcers, and assess for bleeding.

• stool test results: The presence of a dark, tarry stool indicates possible gastrointestinal bleeding (melena). Stool testing, such as a fecal occult blood test, provides objective evidence of bleeding and guides the urgency and necessity of endoscopy. This finding is a key indicator for further gastrointestinal evaluation.

Rationale for incorrect choices

• oxygen via nonrebreather mask: The client’s respiratory assessment shows bilateral clear breath sounds and no signs of hypoxia. Oxygen therapy is not indicated based on current findings, as there is no respiratory compromise.

• an antifungal prescription: There is no evidence of fungal infection. The client’s symptoms are consistent with gastrointestinal pathology, not a fungal etiology. Prescribing an antifungal would be inappropriate without clinical or laboratory indications.

• respiratory rate: The respiratory rate is normal and does not correlate with the presenting gastrointestinal symptoms. It is not a primary indicator for diagnostic intervention in this case.

• temperature: The client does not report fever or signs of infection at this time. While monitoring temperature is standard, it is not a primary indicator for diagnosing peptic ulcer disease or gastrointestinal bleeding in this scenario.
