Which physical assessment findings would the nurse anticipate for a client with rapid atrial flutter?

Visual changes, anorexia

Polyuria, polydipsia

Palpitations, shortness of breath

Systolic murmur, severe anxiety

Answer and Explanation

The Correct Answer is C

A.   These are not typical symptoms of atrial flutter. They may be seen in other conditions like hypertensive crisis or systemic problems, but not as a primary manifestation of atrial flutter.
B.   These are classic signs of diabetes or hyperglycemia, not atrial flutter.
C.   These are common symptoms of atrial flutter, which results in an irregular heart rhythm and may cause increased heart rate, leading to palpitations and shortness of breath.
D.   A systolic murmur is more associated with valve problems, and anxiety could be a result of various issues but is not a typical finding directly caused by atrial flutter.

Correct Answer is C

Explanation

A. This test set is incomplete for diagnosing DIC. While PT and fibrinogen are important, the eosinophil count is not a key test for DIC.
B. While fibrin degradation products are useful, lactic acid is not specific for DIC and may indicate other issues. A complete blood count is helpful but not definitive for diagnosing DIC.
C. These are key markers for DIC. An elevated D-dimer indicates clot formation and breakdown, while fibrinogen and fibrin degradation products are used to assess clotting and fibrinolysis, both of which are abnormal in DIC.
D. Complete blood count, complete metabolic panel, and prothrombin time are general tests and can give some clues, but they are not definitive for diagnosing DIC.

A. Sodium B. Magnesium C. Calcium D. Potassium

Correct Answer is B

Explanation

A. Sodium is crucial for maintaining normal cellular function, especially for nerve impulses and muscle contractions. However, sodium imbalances typically affect the general function of the heart, and sodium abnormalities are not commonly associated with torsades de pointes, which is a type of polymorphic ventricular tachycardia.
B. Magnesium plays a critical role in the electrical stability of the heart and helps regulate potassium and calcium channels, which are involved in the cardiac action potential. Hypomagnesemia (low magnesium) is a well-known risk factor for torsades de pointes, a specific type of polymorphic ventricular tachycardia that is associated with QT interval prolongation. In this case, the magnesium level is 2.5 mg/dL, which is above the normal range (1.6-2.2 mg/dL), suggesting hypermagnesemia.
C. Calcium is vital for proper muscle function, including the heart muscle, and is essential for electrical conduction. Hypocalcemia (low calcium) can lead to QT interval prolongation, which in turn increases the risk for arrhythmias such as torsades de pointes. However, in this case, the calcium level is 8.0 mg/dL, which is only slightly below the normal range (8.2-10.2 mg/dL), making calcium a less likely primary contributor to torsades de pointes in this situation.
D. Potassium plays a crucial role in regulating the resting membrane potential and action potentials in cardiac cells. Hypokalemia (low potassium) can lead to QT prolongation and increase the risk of arrhythmias, including torsades de pointes. However, in this case, the potassium level is 2.8 mEq/L, which is low (normal range: 3.5-5.3 mEq/L), and hypokalemia is more commonly associated with arrhythmias such as torsades de pointes than hyperkalemia (high potassium).
