A patient has difficulty in breathing. The nurse provides oxygen therapy to the patient, after which the patient feels better. Which principle is involved in this situation?

Choice A rationale:

Intramuscular administration involves injecting medication into muscle tissue, which may result in slower and variable absorption rates. It is not the optimal route for providing fast and complete absorption of Furosemide.

Choice B rationale:

Subcutaneous administration delivers medication into the fatty tissue beneath the skin. While it can be used for some medications, it generally results in slower absorption compared to intravenous administration, and it may not be suitable for Furosemide, which requires rapid action in a severe heart failure situation.

Choice C rationale:

Oral administration involves taking medication by mouth, and the absorption process can be influenced by factors such as gastric emptying and gastrointestinal transit time. In an urgent scenario of severe heart failure, oral administration might be too slow and unpredictable.

Choice D rationale:

Intravenous administration allows for the fastest and most complete absorption of Furosemide. By directly delivering the medication into the bloodstream, it bypasses the absorption barriers of the gastrointestinal tract, leading to rapid onset of action and predictable effects, which is crucial in managing acute heart failure. This route is commonly used in critical situations where immediate therapeutic effects are needed.

Choice A rationale:

Instructing the client not to adjust the oxygen flow rate is crucial to ensure the appropriate amount of oxygen is delivered. Oxygen flow rates are prescribed by a healthcare provider based on the client's needs, and altering the flow rate without medical guidance can lead to inadequate oxygen delivery or oxygen toxicity.

Choice B rationale:

Weekly equipment checks are important, but this choice is not the most critical instruction. Clients should be instructed to check their oxygen equipment daily for proper functioning and to address any issues promptly. Waiting a whole week could lead to potential problems going unnoticed.

Choice C rationale:

Storing unused oxygen tanks horizontally is incorrect. Oxygen tanks should be stored upright to prevent leaks and ensure proper functioning. Storing them horizontally can cause valve damage and leakage, which could lead to hazards.

Choice D rationale:

Using wool blankets on the bed is not a suitable instruction for a client using oxygen therapy. Wool blankets can generate static electricity, which might pose a fire hazard in the presence of oxygen-enriched environments.
