The nurse is evaluating the outcomes for a client diagnosed with disseminated intravascular coagulation (DIC). Which laboratory value reflects a positive outcome?

Decreased D-dimer level

Elevated fibrinogen level

Decreased platelet count

Prolonged prothrombin time (PT)

Answer and Explanation

The Correct Answer is A

A.   A decreased D-dimer level is a positive outcome, as D-dimer is elevated in DIC due to the formation of clots and the breakdown of fibrin. Lower levels indicate less clot formation and better control of the condition.
B.   Fibrinogen levels are typically low in DIC due to consumption of clotting factors. Elevated fibrinogen in this case would be a negative indicator, suggesting that clotting is not resolving.
C.   A decreased platelet count is a hallmark of DIC and indicates ongoing consumption of platelets due to widespread clotting. A decrease would not be a positive outcome.
D.   A prolonged PT is another indicator of DIC, suggesting impaired clotting function. This is not a positive outcome.

Correct Answer is D

Explanation

A. A value of 119 seconds would indicate a therapeutic or even elevated level of heparin, as it is much higher than the normal aPTT range.
B. A value of 98 seconds is still above the normal aPTT range, suggesting that the heparin level is therapeutic, or even too high, but not sub-therapeutic.
C. This is just slightly above the normal range and might be considered a therapeutic range for someone
on heparin, but it’s not sub-therapeutic.
D. This aPTT value is above the normal range but likely not high enough to indicate therapeutic heparin levels, which should typically be between 1.5 to 2.5 times the normal aPTT. A sub-therapeutic level could be indicated with a lower value.

A. Marked limitation with physical activity but comfortable at rest B. Angioedema and urticaria C. Increased urine output D. Chest pain during sleep that is relieved with nitroglycerin

Correct Answer is A

Explanation

A. Clients with left-sided heart failure often experience symptoms like shortness of breath, fatigue, and fluid retention, which limit physical activity. However, they may still feel relatively comfortable when resting.
B. These symptoms are more commonly associated with allergic reactions or side effects of medications (such as ACE inhibitors) rather than heart failure.
C. This is not typical in the later stages of left-sided heart failure. In fact, clients may experience reduced urine output due to poor kidney perfusion.
D. Chest pain can occur due to ischemia, but this is not a hallmark symptom of left-sided heart failure, which is more characterized by dyspnea and fatigue.
