A nurse is preparing to titrate morphine 6 mg via IV bolus to a client. The amount available is morphine 8 mg/mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.75"]
To calculate the volume of solution, use the formula:
mL = (desired dose in mg / available dose in mg) x 1 mL
Plug in the given values:
mL = (6 mg / 8 mg) x 1 mL
Simplify and solve:
mL = 0.75 x 1 mL
mL = 0.75 mL
Round to the nearest hundredth and add a leading zero if needed:
mL = 0.75 mL

Correct Answer is ["A","D"]
Explanation
Answer: A, D
Rationale:
-
A. The medication will prevent wheezing: Albuterol is a bronchodilator, specifically a beta-2 agonist, that relaxes smooth muscles in the airways. This action helps prevent wheezing by reducing airway constriction, making breathing easier for the client.
-
B. The medication will decrease coughing episodes: While albuterol can help reduce cough indirectly by improving airflow and decreasing airway irritation, it is not primarily used to decrease coughing episodes. Other medications, such as corticosteroids, are often more effective for controlling chronic cough related to inflammation.
-
C. The medication will reduce inflammation: Albuterol does not have anti-inflammatory properties. Its primary mechanism is bronchodilation, and anti-inflammatory treatment generally requires corticosteroids, not beta-agonists like albuterol.
-
D. The medication will open the airways: Albuterol works by relaxing bronchial muscles, leading to bronchodilation and allowing the airways to open. This reduces shortness of breath and improves airflow, a primary reason for its use in conditions like asthma.
-
E. The medication will stimulate flow of mucus: Albuterol does not stimulate mucus production; it primarily works by relaxing the airways. However, by improving airflow, it can help clients more effectively expel mucus through coughing.
Correct Answer is C
Explanation
Increased anteroposterior diameter of the chest, also known as barrel chest, is a common finding in clients who have COPD with emphysema. It is caused by chronic air trapping and hyperinflation of the lungs, which results in fattening of the diaphragm and widening of the rib cage.
a) Oxygen saturation level 96% is within the normal range of 95% to 100% and does not indicate hypoxemia or impaired gas exchange. Clients who have COPD with emphysema typically have lower oxygen saturation levels, ranging from 88% to 92%.
b) Respiratory alkalosis is a condition in which the blood pH is elevated due to decreased carbon dioxide levels. It is caused by hyperventilation, which can occur in response to hypoxia, anxiety, or pain. Clients who have COPD with emphysema usually have respiratory acidosis, which is a condition in which the blood pH is lowered due to increased carbon dioxide levels. It is caused by hypoventilation, which results from impaired lung function and airway obstruction.
d) Petechiae on chest are small red or purple spots on the skin caused by bleeding from capillaries. They are not a typical finding in clients who have COPD with emphysema, unless they have severe coughing episodes or coagulation disorders. They can indicate infection, inflammation, trauma, or vascular disease.
