A nurse is caring for a client who is newly diagnosed with cancer.
Which of the following is a correct statement about cancer?

Choice A rationale

Albuterol is a bronchodilator used to relax muscles in the airways and increase airflow to the lungs. It is primarily used in conditions such as asthma and chronic obstructive pulmonary disease (COPD), not as a decongestant.

Choice B rationale

Beclomethasone is a corticosteroid used to reduce inflammation in conditions such as asthma and allergic rhinitis. While it helps with symptoms, it is not classified as a decongestant.

Choice C rationale

Diphenhydramine is an antihistamine that alleviates allergy symptoms by blocking histamine action. It can relieve sneezing, itching, and runny nose but is not classified as a decongestant.

Choice D rationale

Phenylephrine is a decongestant that works by constricting blood vessels in the nasal passages. This reduces swelling and congestion, making it effective for managing symptoms of allergic rhinitis. .

Choice A rationale: Furosemide is a loop diuretic used to reduce fluid overload in CHF patients. However, it can exacerbate electrolyte imbalances, particularly hypokalemia. Since the client is already experiencing muscle spasms and has low calcium levels, additional diuretic therapy could worsen these symptoms.

Choice B rationale: Metoprolol is a beta-blocker used to manage hypertension and heart rate in CHF patients. While beneficial for blood pressure control, it does not address the immediate issue of muscle spasms and constipation the client is experiencing.

Choice C rationale: Potassium chloride is indicated to address potential hypokalemia, which may be causing the client's muscle spasms. CHF patients on diuretics often experience low potassium levels, so supplementation is crucial to prevent complications and alleviate symptoms.

Choice D rationale: Acetaminophen is an analgesic and antipyretic, useful for pain and fever management. However, it does not address the client's reported muscle spasms, which are likely related to electrolyte imbalances.
