Cephalosporin

Sulfonamide

Penicillin

Fluroquinolone

Answer and Explanation

The Correct Answer is C

A.   Cephalosporins are a class of antibiotics that can, in some cases, cause liver enzyme elevations and hepatotoxicity. While not all cephalosporins are associated with significant liver toxicity, there have been reports of liver dysfunction with some members of this class.
B.   Sulfonamides can also cause hepatotoxicity, particularly in certain individuals. They are known to occasionally lead to liver enzyme elevations and even more severe liver damage in susceptible patients.
C.   Penicillins are generally considered safe regarding hepatotoxicity; however, there can be rare instances of liver enzyme elevation associated with some penicillin derivatives, particularly in cases of prolonged use or in patients with existing liver disease. Nonetheless, they are not commonly associated with significant hepatotoxicity.
D.   Fluoroquinolones can cause liver toxicity, although it is relatively rare. Some fluoroquinolones have been associated with elevated liver enzymes and other hepatic issues.

Correct Answer is ["A","D"]

Explanation

A. Patients are often advised to avoid straining during bowel movements and bending at the waist to reduce intraocular pressure and the risk of complications after cataract surgery. This is crucial for promoting healing and preventing dislodgement of the lens.
B. While good lighting can be important for safety and visibility, patients are often advised to avoid excessively bright lights or glare, especially after surgery, as it can be uncomfortable and may not be beneficial during the recovery period. Patients may need to use softer lighting to avoid discomfort.
C. After cataract surgery, patients are typically advised to lie on their back or the non-operative side to avoid pressure on the eye that underwent surgery. Lying on the abdomen is not recommended and could pose a risk to the surgical site.
D. Patients are often instructed to avoid heavy lifting for a period after surgery to prevent increased intraocular pressure and potential complications. Lifting more than 15 lbs is generally discouraged during the initial recovery phase.

A. Apply a thick coat of calamine lotion over open lesions. B. Give diphenhydramine by mouth. C. Apply a cool cloth to the rash. D. Give ibuprofen or acetaminophen.

Correct Answer is C

Explanation

A. While calamine lotion can be soothing and help alleviate itching, applying a thick coat over open lesions is not advisable. It may not allow the skin to breathe and can potentially lead to further irritation or infection. Therefore, while this option has some merit, it is not the priority intervention.
B. Diphenhydramine (Benadryl) is an antihistamine that can help relieve itching. This option can be beneficial for managing pruritus and may help the child sleep better. However, while it can be useful, there are other interventions that can provide immediate comfort more effectively.
C. Applying a cool cloth to the rash is an immediate and effective way to provide comfort and relieve itching. The coolness can soothe inflamed skin and reduce the urge to scratch, which helps prevent secondary infections.
D. While giving ibuprofen or acetaminophen can help reduce fever and discomfort associated with varicella, it does not specifically address pruritus. These medications are helpful for pain management but are not the best choice for alleviating itching directly.
