The nurse should teach a patient to observe which side effects when taking ampicillin.

A. Ototoxicity and Nephrotoxicity:
Ototoxicity: Aminoglycosides can damage the inner ear structures, leading to hearing loss and balance issues.
Nephrotoxicity: These drugs can harm the kidneys, potentially causing acute kidney injury or chronic kidney disease. Monitoring kidney function is crucial to prevent renal damage.

B. Ototoxicity and Cardiotoxicity:
Ototoxicity: As mentioned above, aminoglycosides can damage the inner ear, affecting hearing and balance.
Cardiotoxicity: Aminoglycosides primarily affect the ears and kidneys; they do not directly target the heart. Cardiotoxicity is not a common side effect associated with aminoglycosides.

C. Hepatotoxicity and Nephrotoxicity:
Hepatotoxicity: This term refers to liver damage caused by drugs or toxins. Aminoglycosides are not known to cause liver problems; their primary concern is kidney damage.
Nephrotoxicity: As mentioned earlier, aminoglycosides can harm the kidneys, which is a well-known side effect.

D. Cardiotoxicity and Hepatotoxicity:
Cardiotoxicity: This term refers to the toxic effects on the heart, leading to various heart-related issues. Aminoglycosides do not primarily affect the heart; their main concerns are the ears (ototoxicity) and kidneys (nephrotoxicity).
Hepatotoxicity: Aminoglycosides are not typically associated with liver damage. They are primarily metabolized and excreted by the kidneys, which is why kidney monitoring is crucial during their use.

A. Type IV Hypersensitivity (Delayed Hypersensitivity Reaction): This type of reaction involves a delayed immune response, typically occurring 24 to 72 hours after exposure to an antigen. It's characterized by the activation of T cells and macrophages, leading to inflammation. This type of hypersensitivity is often associated with conditions like contact dermatitis and some autoimmune diseases.

B. Type III Hypersensitivity (Antibody-Mediated Reaction): Type III hypersensitivity reactions occur when immune complexes, which are composed of antigens and antibodies, deposit in various tissues. This leads to inflammation and tissue damage. Systemic lupus erythematosus (SLE) is an example of a disease associated with Type III hypersensitivity.

C. Type II Hypersensitivity: This type of reaction involves antibodies (IgG or IgM) targeting antigens on the surface of cells. This can lead to cell destruction through various mechanisms, such as complement activation or antibody-dependent cell-mediated cytotoxicity (ADCC). Examples include hemolytic transfusion reactions and autoimmune hemolytic anemia.

D. Type I Hypersensitivity (Immediate Hypersensitivity Reaction): Type I hypersensitivity is characterized by an immediate immune response, typically occurring within minutes of exposure to an allergen. It involves the release of histamines and other mediators from mast cells and basophils, leading to symptoms like hives, respiratory distress, and anaphylaxis. Allergies, like hay fever and food allergies, are examples of Type I hypersensitivity reactions.
