1. Group of answer choices

2. The client's calcium will rise dramatically due to pituitary stimulation.

3. Oxygen will increase the client's intracranial pressure and create confusion.

5. Using oxygen may result in the client hypoventilating leading to increased hypercapnia

An older adult client diagnosed with hypertension and cardiac disease is experiencing a cold. The client asks the nurse what medications the client can take. Which groups of medications should the nurse suggest? Select all that apply.

1. Oral nasal decongestants such as pseudoephedrine.
2. Oral expectorants such as guaifenesin.
3. Locally acting antitussives such as cough drops.
4. An antacid such as calcium carbonate

Answer 1

Answer 1) If the client's CO2 is between 56 and 64 mm Hg for some months. Nurse should be cautious because using oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.

Actually when PaCO2 chronically exceeds 50 mm Hg, it create insensitivity to CO2 in the respiratory medulla and the use of oxygen may resulting the patient to develop carbon dioxide narcosis and hypoxemia.

Answer 2) option A

This disease is diagnosed with rhinosinusitis and mostly prescribed topical oxymetazoline. So, over the counter pseudoephedrine should suggest.
