A Medical-Surgical nurse is preparing to administer Furosemide to a patient who is having severe heart failure. Which route of administration should the nurse use to provide the fastest and most complete absorption of Furosemide?

The correct answer is: d. Left fifth intercostal space at the midclavicular line.

Choice A: Left fourth intercostal space at the sternal border

The fourth intercostal space at the sternal border is not the typical location for the Point of Maximal Impulse (PMI). This area is more commonly associated with the tricuspid valve auscultation point. The PMI is usually found more laterally and inferiorly.

Choice B: Left third intercostal space at the sternal border

The third intercostal space at the sternal border is also not the correct location for the PMI. This area is generally used for auscultating the pulmonic valve. The PMI is located further down and towards the midclavicular line.

Choice C: Left second intercostal space at the midclavicular line

The second intercostal space at the midclavicular line is typically where the aortic valve is auscultated. The PMI is not found this high up on the chest.

Choice D: Left fifth intercostal space at the midclavicular line

This is the correct location for palpating the Point of Maximal Impulse (PMI). The PMI is usually located at the apex of the heart, which is found at the left fifth intercostal space along the midclavicular line. This is where the left ventricle is closest to the chest wall and can be felt most strongly during systole.

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.
