Question 1

A patient on mechanical ventilation develops sudden hypoxia, decreased breath sounds on the left, and tracheal deviation to the right. The ACNP's immediate action should be:

Accepted Answer

Perform needle decompression at the second intercostal space, midclavicular line

Answer

Tension pneumothorax requires immediate needle decompression; delaying for imaging is life-threatening.

Question 2

Which hemodynamic pattern is most consistent with cardiogenic shock?

Accepted Answer

High CVP, high PCWP, low CO, high SVR

Answer

Cardiogenic shock presents with elevated filling pressures, reduced cardiac output, and compensatory increased systemic vascular resistance.

Question 3

A patient with chronic kidney disease stage 4 has a potassium of 6.8 mEq/L with peaked T-waves on ECG. The first intervention should be:

Accepted Answer

IV calcium gluconate

Answer

IV calcium gluconate stabilizes the cardiac membrane immediately, which is the priority when ECG changes are present.

Question 4

When interpreting a bronchoalveolar lavage (BAL) result showing >15% hemosiderin-laden macrophages, the ACNP should suspect:

Accepted Answer

Diffuse alveolar hemorrhage

Answer

Hemosiderin-laden macrophages in BAL indicate prior alveolar bleeding, consistent with diffuse alveolar hemorrhage.

Question 5

A post-operative patient develops fever (38.8°C), tachycardia, and confusion on day 2. Blood cultures are pending. The ACNP should initiate empiric antibiotics targeting:

Accepted Answer

Broad-spectrum coverage including gram-negative organisms

Answer

Early post-operative sepsis requires broad-spectrum coverage until culture sensitivities narrow treatment.
