The drug of choice for methicillin-resistant staphylococcus aureus (MRSA) is:
Gentamicin
Nafcillin
Vancomycin
Penicillin
The Correct Answer is C
A. Gentamicin: Gentamicin is an aminoglycoside antibiotic effective against many bacteria, but it's not the first choice for MRSA. Vancomycin or other alternatives are preferred due to the rising resistance of MRSA to gentamicin.
B. Nafcillin: Nafcillin is a penicillin antibiotic, often used for penicillin-sensitive staphylococcal infections. However, it is not effective against MRSA, which is resistant to many penicillin-based antibiotics.
C. Vancomycin: Vancomycin is a glycopeptide antibiotic used to treat a variety of bacterial infections, including MRSA. It works by inhibiting cell wall synthesis in bacteria, making it effective against Gram-positive bacteria that have developed resistance to other antibiotics like methicillin (which MRSA has).
D. Penicillin: Penicillin is a group of antibiotics that includes drugs like amoxicillin and ampicillin. MRSA is resistant to penicillin-based antibiotics, so they are not effective against MRSA infections.

Correct Answer is C
Explanation
A. Dermatitis and headaches: Prednisone use can sometimes cause skin issues, but dermatitis is not a common side effect. Headaches can also occur, but they are not specific to long-term prednisone therapy.
B. Heart failure and headaches: Prednisone does not directly cause heart failure. Headaches can occur but are not specific indicators of prednisone side effects.
C. Hyperglycemia and osteoporosis: Prednisone can lead to elevated blood glucose levels (hyperglycemia) and increased bone loss (osteoporosis) when used long-term. Regular monitoring is essential to manage these potential side effects.
D. Weight loss and hypoglycemia: Prednisone can cause weight gain rather than weight loss. Hypoglycemia (low blood sugar) is not a common side effect of prednisone; it typically causes hyperglycemia (high blood sugar) instead.
Correct Answer is D
Explanation
A. Respiratory Function: Monitoring respiratory function is important for conditions like asthma or chronic obstructive pulmonary disease (COPD). It involves assessing lung sounds, oxygen saturation levels, and breathing patterns. This monitoring is essential to detect any signs of respiratory distress.
B. Cardiac Function: Monitoring cardiac function includes assessing heart rate, blood pressure, and rhythm. It's crucial for patients with heart conditions like heart failure or arrhythmias. This monitoring helps in identifying irregularities in heart function and provides insights into the overall cardiovascular health of the patient.
C. Renal Function: Monitoring renal function involves assessing kidney health, which includes tests like serum creatinine and glomerular filtration rate (GFR). This is vital for patients with kidney diseases or those taking medications that can impact kidney function. Monitoring renal function helps in detecting any signs of kidney impairment or failure.
D. Liver Function: Monitoring liver function involves tests like liver enzymes (AST, ALT), bilirubin levels, and albumin levels. This is essential for patients taking medications that can affect the liver, such as certain antifungals, statins, or pain relievers. Monitoring liver function helps in identifying liver damage or dysfunction early on.
