A nurse is assessing a client who has disseminated intravascular coagulation (DIC). Which of the following findings should the nurse expect?
Excessive thrombosis and bleeding
Increased clotting factors
Progressive increase in platelet production
Immediate sodium and fluid retention
The Correct Answer is A
A. Excessive thrombosis and bleeding
Disseminated Intravascular Coagulation (DIC) is a complex and serious condition characterized by widespread activation of the coagulation cascade, leading to both excessive clot formation (thrombosis) and simultaneous consumption of clotting factors and platelets, resulting in bleeding. DIC can occur as a secondary complication to various conditions such as sepsis, trauma, or obstetric complications.
B. Increased clotting factors: In DIC, there is consumption and depletion of clotting factors, not an increase.
C. Progressive increase in platelet production: Platelet production does not increase in DIC; instead, there is consumption and decreased platelet count.
D. Immediate sodium and fluid retention: DIC is not associated with immediate sodium and fluid retention; instead, it is characterized by fluid loss due to bleeding.

Explanation
Asthma action plans often use a color-coded system to guide management based on peak expiratory flow rate (PEFR) measurements. The zones are typically green (80-100% of personal best), yellow (50-79% of personal best), and red (less than 50% of personal best).
A. The student needs to go to the hospital.
This is not necessarily required when the student is in the yellow zone. The yellow zone indicates caution and the need for intervention, but it does not immediately require hospitalization unless symptoms worsen or do not improve after using the quick-relief inhaler.
B. The nurse should obtain a second expiratory flow rate.
Confirming the peak flow measurement with a second reading ensures accuracy and helps to make informed decisions about the student's asthma management.
C. The student should use his quick-relief inhaler.
In the yellow zone, indicating moderate impairment, the use of a quick-relief (rescue) inhaler is often recommended to relieve symptoms and prevent progression to the red zone.
D. The student's peak flow is 50% to 80% of his best peak flow.
This is the correct range for the yellow zone, indicating moderate impairment. Action is needed to prevent worsening.
E. The student's asthma is not well controlled.
Being in the yellow zone indicates that the asthma is not well controlled and may require adjustments in the long-term management plan, including possible changes to daily controller medications.
Correct Answer is A
Explanation
A. Fatigue: Hypokalemia (low potassium levels) can lead to fatigue and weakness. Potassium is essential for proper muscle and nerve function, and a deficiency can result in muscle weakness and decreased energy levels.
B. Pitting edema: Pitting edema is more commonly associated with fluid retention, which can occur in heart failure. Hypokalemia is not typically a direct cause of pitting edema.
C. Dyspnea: Dyspnea (shortness of breath) is a symptom commonly associated with heart failure, and while potassium imbalance can affect cardiac function, it is not a specific manifestation of hypokalemia.
D. Oliguria: Oliguria (decreased urine output) is not a typical manifestation of hypokalemia. However, it can be associated with heart failure and other renal conditions.
