A nurse is preparing to administer hydrocortisone 100 mg IM daily to a client. Available is hydrocortisone 250 mg/2 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
To calculate the amount of mL to administer, the nurse should use the following formula:
(mg ordered / mg available) x mL available = mL to administer
Substituting the values from the question, the nurse should do the following:
(100 mg / 250 mg) x 2 mL = 0.8 mL

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.
Correct Answer is C
Explanation
Increasing fluid intake helps to hydrate the mucous membranes and thin the respiratory secretions, which facilitates expectoration and improves gas exchange.
- Encourage coughing and deep breathing. This is beneficial for clearing the airways and preventing atelectasis, but it does not directly affect the viscosity of the secretions.
- Encourage regular use of the incentive spirometer. This is helpful for expanding the lungs and preventing complications such as pneumonia or pleural effusion, but it does not influence the consistency of the secretions.
- Encourage the client to ambulate frequently. This is important for promoting circulation and mobility, but it does not have a significant effect on the thinning of the secretions.
