A nurse working in the emergency department (ED) is admitting a female client

The nurse is reviewing the client's medical record. Which of the following conditions should the nurse identify as a risk factor for pneumonia? Select all that apply.

Rationale for correct choices

• Stroke: The client developed new-onset atrial fibrillation with a rapid ventricular response, which significantly increases the risk for thrombus formation and subsequent embolic stroke. Atrial fibrillation after cardiac surgery can lead to stasis of blood in the atria, particularly the left atrial appendage, predisposing the client to cerebrovascular events.

• Cardiac rhythm: Monitoring cardiac rhythm is essential because changes such as atrial fibrillation, tachyarrhythmias, or pauses indicate altered hemodynamics and potential complications. The irregular, rapid atrial fibrillation observed at 1130 highlights the client’s immediate risk for embolic events. Continuous cardiac monitoring allows prompt recognition and intervention to prevent stroke

Rationale for incorrect choices

• Atelectasis: Atelectasis would present with diminished lung sounds, crackles, dyspnea, or hypoxemia. In this case, lung sounds are clear bilaterally, oxygen saturation is slightly decreased but not critically low, and the client reports no respiratory distress. These findings make atelectasis less likely.

• Cardiac tamponade: Cardiac tamponade is characterized by hypotension, jugular venous distension, muffled heart sounds, and tachycardia. Although the client has tachycardia, blood pressure is only mildly decreased, JVD is absent, and heart sounds are normal. These findings do not support cardiac tamponade at this time.

• Pneumothorax: Pneumothorax would present with diminished or absent lung sounds on the affected side, sudden dyspnea, and decreased oxygen saturation. Lung sounds are clear bilaterally, chest tubes are patent, and oxygen saturation is only slightly decreased, which is insufficient evidence for pneumothorax.

• Infection: Early postoperative infection might present with fever, redness, or drainage at surgical sites. The client’s dressings are clean, dry, and intact, with only a mild temperature elevation, which may be a normal postoperative response rather than a true infection. There is no other clinical evidence to support infection as an immediate concern.

• Chest tube assessment: Chest tube assessment is important for monitoring pneumothorax or fluid accumulation but is not related to the immediate risk of stroke. The chest tubes are patent, with tidaling present and no air leak, indicating proper function. This parameter does not reflect the client’s thromboembolic risk.

• Lung sounds: Lung sounds are clear and do not indicate respiratory compromise or atelectasis. While important for overall assessment, lung auscultation does not provide evidence of the client’s risk for stroke in the context of new atrial fibrillation.

• Heart sounds: Heart sounds are normal with no extra sounds or murmurs. While auscultation is part of cardiac assessment, the primary risk for stroke is related to the cardiac rhythm rather than auscultatory findings.

• Dressing assessment: Dressings are clean, dry, and intact, indicating no current surgical site complications. This parameter does not contribute to identifying the client’s stroke risk.

A. Group B streptococcus β-hemolytic status: The client is GBS negative, which does not indicate a labor complication. This finding decreases the need for intrapartum antibiotic prophylaxis and does not pose a risk to the fetus or labor progress at this time.

B. Maternal heart rate: The maternal heart rate is 110/min, which is elevated and may indicate early systemic infection, especially when paired with fever. Tachycardia during labor can signal maternal distress or infection and requires prompt assessment to prevent maternal and fetal complications.

C. Contraction pattern: Contractions are occurring every 5 minutes for the past hour but are not described as coordinated or progressing normally. In the presence of infection markers such as fever and tachycardia, this pattern may suggest dysfunctional labor, where infection or inflammation disrupts normal uterine activity.

D. Vaginal discharge: The discharge is described as malodorous and nitrazine-positive, findings that strongly suggest possible chorioamnionitis or another infectious process. Odorous fluid associated with ruptured membranes requires immediate provider notification due to risks of neonatal sepsis.

E. Cervical assessment: The client is now 3 cm dilated, which is appropriate for early labor in a primigravida and does not indicate a complication. This finding aligns with expected cervical changes leading toward active labor.

F. Pain rating: A pain score of 4 at rest and 8 during contractions is typical for early labor and does not represent a complication. Pain naturally increases as contractions strengthen and the cervix dilates, reflecting normal physiologic progression.

G. Temperature: A temperature of 38.7°C (101.7°F) indicates maternal fever, a significant concern during labor. Fever in combination with tachycardia and abnormal discharge suggests intra-amniotic infection, which can rapidly progress and threaten both maternal and fetal well-being.
