A nurse is teaching a client who has septic shock about the development of disseminated intravascular coagulation (DIC). Which of the following statements should the nurse make?

"DIC is controllable with lifelong heparin usage."

"DIC is caused by abnormal coagulation involving fibrinogen."

"DIC is a genetic disorder involving a vitamin K deficiency."

"DIC is characterized by an elevated platelet count."

Answer and Explanation

The Correct Answer is B

A. "DIC is controllable with lifelong heparin usage": This statement is not accurate. While heparin may be used in the treatment of DIC, it is not a lifelong therapy, and the approach to treatment depends on the underlying cause.

B. "DIC is caused by abnormal coagulation involving fibrinogen": This is the correct answer. DIC is a condition characterized by widespread activation of the clotting cascade, leading to the formation of microthrombi throughout the body. Abnormal coagulation involves the consumption of clotting factors, including fibrinogen.

C. "DIC is a genetic disorder involving a vitamin K deficiency": This statement is not accurate. DIC is not a genetic disorder, and it is not primarily related to vitamin K deficiency. It is an acquired condition often associated with severe infections, sepsis, trauma, or other critical illnesses.

D. "DIC is characterized by an elevated platelet count": This statement is not accurate. In DIC, there is often a decrease in platelet count due to consumption and activation of platelets in the widespread formation of microthrombi.

Correct Answer is ["B","C","D","E"]

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.

A. It requires lying quietly on one side." B. It might cause slight discomfort in the chest area." C. "It is best to have no food or beverages the day of the test." D. "It takes about 5 or 10 minutes."

Correct Answer is A

Explanation

A. "It requires lying quietly on one side": This is the correct answer. During an echocardiogram, the client is typically asked to lie on their left side to obtain clear images of the heart. The test is non-invasive and involves using ultrasound waves to create images of the heart's structures.

B. "It might cause slight discomfort in the chest area": Echocardiograms are generally painless and do not cause discomfort. They are a non-invasive imaging technique that uses sound waves.

C. "It is best to have no food or beverages the day of the test": While the client may be instructed to avoid eating or drinking shortly before the test, this statement is too restrictive. The specific fasting instructions will be provided by the healthcare provider or facility.

D. "It takes about 5 or 10 minutes": The duration of an echocardiogram can vary, but it typically takes longer than 5 or 10 minutes. The test duration depends on various factors, including the complexity of the study and the information needed.
