The nurse is viewing orders for a client with a suspected diagnosis of disseminated intravascular coagulation (DIC). The nurse recognizes that which laboratory test order set will guide the provider to a diagnosis of DIC?

Prothrombin time, fibrin level and eosinophil count

Fibrin degradation products, lactic acid and complete blood count

D-dimer, fibrinogen and fibrin degradation products

Complete blood count, Complete metabolic panel and prothrombin time

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is C

Explanation

A. Mobitz II is a type of second-degree AV block characterized by constant PR intervals and sudden dropped QRS complexes (i.e., the PR interval does not lengthen progressively). This is a more serious block because the dropped beats are unpredictable and could lead to complete block.
B. Sinus bradycardia is a slower-than-normal heart rate (usually less than 60 beats per minute) that originates from the sinus node. First-degree AV block is characterized by a prolonged PR interval, but unlike second-degree block, there are no dropped QRS complexes.
C. Mobitz I (Wenckebach) is a second-degree AV block where the PR interval gradually lengthens with each successive beat until a QRS complex is dropped. After the dropped beat, the cycle repeats. This is a relatively benign block and often resolves without intervention, though it requires monitoring.
D. Third-degree heart block (also known as complete heart block) occurs when there is no communication between the atria and ventricles. The atria and ventricles beat independently of each other. There are no relationship between the P waves and QRS complexes, and the ventricular rate is typically slower than the atrial rate.

A. “I will be ready to resume participation in the football league in two weeks.! B. 'It is safe to use the microwave oven to heat up food." C. “I can use my cellphone as long as I keep it 6 inches away from the device." D. "The defibrillator will feel like a kick or blow to the chest if it fires."

Correct Answer is A

Explanation

A. This statement indicates a need for further education. After receiving an ICD, clients must refrain from engaging in vigorous physical activities such as contact sports (e.g., football) for a longer period of time to avoid injury or triggering the defibrillator. A longer recovery period is typically recommended.
B. This is correct. Microwaves do not affect the function of an ICD, so it is safe to use one.
C. This is correct. The client should keep their cellphone at least 6 inches away from the ICD to avoid interference with the device.
D. This is correct. Clients may experience a sudden, forceful sensation similar to a kick or blow when the ICD delivers a shock to correct an arrhythmia.
