The nurse is caring for a client who is in the later stages of left-sided heart failure. Which chief complaint would the nurse expect the client to report?
Marked limitation with physical activity but comfortable at rest
Angioedema and urticaria
Increased urine output
Chest pain during sleep that is relieved with nitroglycerin
The Correct Answer is A
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.

Correct Answer is A
Explanation
A. Cyanosis, or a bluish discoloration of the skin, occurs when there is insufficient oxygen in the blood, which can result from decreased perfusion due to clotting in DIC. It is a sign of poor oxygenation and perfusion.
B. While petechiae (small red or purple spots) are a common manifestation of DIC due to microvascular clotting and bleeding, they are not a sign of decreased perfusion.
C. Epistaxis (nosebleeds) is another bleeding manifestation of DIC but is not indicative of decreased perfusion, which is more closely related to cyanosis.
D. Hematuria (blood in the urine) can occur in DIC due to clotting in the kidneys or urinary tract. However, it is more related to bleeding than to decreased perfusion.
Correct Answer is ["11"]
Explanation
The patient weighs 121 lbs, which is approximately 55 kilograms (121 ÷ 2.2).
Next, multiply the patient's weight in kilograms by the dosage prescribed, which is 20 units/kg. This results in a total dosage of 1100 units (55 kg × 20 units/kg).
The medication is supplied as 25,000 units in 250 mL, so to find out how many mL of medication is needed, set up a proportion: 25,000 units is to 250 mL as 1100 units is to X mL. Solving for X gives you 11 mL (1100 units × 250 mL ÷ 25,000 units).
Therefore, the nurse will administer 11 mL of Heparin to the patient.
