PCCN Medical Conditions & Symptoms

Question 1

Which clinical manifestation is most concerning in a patient with suspected sepsis?

Accepted Answer

Blood pressure 86/52 mmHg

Answer

A blood pressure of 86/52 mmHg indicates hypotension, which is a critical sign of septic shock. Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Hypotension in sepsis signifies inadequate tissue perfusion and is a medical emergency requiring immediate fluid resuscitation and vasopressors to prevent irreversible organ damage and death.

Question 2

A diabetic patient presents with fruity-smelling breath, confusion, and rapid, deep respirations. Which condition should the nurse suspect?

Accepted Answer

Diabetic ketoacidosis (DKA)

Answer

Diabetic ketoacidosis (DKA) is a severe complication of diabetes characterized by hyperglycemia, metabolic acidosis, and the presence of ketones. The classic signs include fruity-smelling breath (due to acetone), confusion (due to acidosis and dehydration), and Kussmaul respirations (rapid, deep breathing) as the body attempts to compensate for the acidosis.

Question 3

Which symptom is most specific for myocardial infarction (MI) in older adult women?

Accepted Answer

Jaw pain and fatigue

Answer

Older adult women often experience atypical symptoms of myocardial infarction (MI) compared to the classic crushing chest pain. Their symptoms can be more subtle and non-specific, including unusual fatigue, shortness of breath, nausea, and pain in the jaw, neck, or back. Recognizing these atypical presentations is crucial for timely diagnosis and intervention in this population.

Question 4

Which electrolyte imbalance is most associated with mental status changes and muscle cramps?

Accepted Answer

Hyponatremia

Answer

Hyponatremia, a low serum sodium level, significantly affects neurological function because sodium is critical for nerve impulse transmission and maintaining fluid balance in brain cells. Symptoms often include mental status changes such as confusion, lethargy, and disorientation, as well as muscle cramps, weakness, and seizures in severe cases.

Question 5

What is a priority nursing concern in a patient with suspected deep vein thrombosis (DVT)?

Accepted Answer

Potential for pulmonary embolism

Answer

Deep vein thrombosis (DVT) involves the formation of a blood clot in a deep vein, most commonly in the legs. The most serious and life-threatening complication of a DVT is a pulmonary embolism (PE), which occurs if a piece of the clot breaks off and travels to the lungs, obstructing blood flow. Therefore, preventing PE is the paramount concern in DVT management.
