The nurse is to administer heparin to a client who weighs 90 pounds. Heparin is ordered as 10,000 units/100mL. The nurse needs to administer a bolus of 40units/kg. How many units would the nurse administer? (Round to the nearest tenth)
Answer and Explanation

The Correct Answer is ["1636.4"]

  • Convert pounds to kilograms:
    • Weight in kilograms = 90 pounds / 2.2 pounds/kg = 40.9090... kg. For practical purposes, we can round to 40.91kg.
  • Calculate the heparin dose:
    • The ordered bolus dose is 40 units/kg.
    • Heparin dose = 40.91 kg  40 units/kg = 1636.4 units.
  • Round to the nearest tenth:
    • The heparin dose is 1636.4 units.

 = 1636.4 units

Correct Answer is B

Explanation

A. Stress testing evaluates cardiac function and ischemia but is not used to diagnose a pulmonary embolism (PE).
B. D-Dimer is correct. D-Dimer is a blood test that detects fibrin degradation products, which are elevated when a blood clot forms and breaks down, making it a useful screening test for pulmonary embolism. However, a positive D-Dimer is not diagnostic, and further imaging (e.g., CT pulmonary angiography) is required.
C. Electrocardiogram (ECG) may show changes (e.g., sinus tachycardia, right heart strain) but does not confirm PE.
D. Pulmonary function testing assesses lung diseases like COPD or asthma but is not used to diagnose PE.

Correct Answer is A

Explanation

A. Pleural effusion is a common complication of heart failure. Increased pressure in the pulmonary circulation can cause fluid to accumulate in the pleural space, leading to dyspnea and decreased lung expansion.
B. Infection is not a direct complication of heart failure. However, individuals with heart failure may have an increased risk of infections due to a weakened immune system.
C. Asthma is not a complication of heart failure. While both conditions can cause shortness of breath, asthma is a separate respiratory disorder.
D. Hemorrhage is not associated with heart failure. Instead, heart failure can lead to clotting abnormalities or increased bleeding risk if the client is on anticoagulants.
