Macrolides
Fluoroquinolones
Aminoglycosides
Penicillins
The Correct Answer is D
Cephalosporins are similar to another group of beta-lactam antibiotics called the Penicillins. Both cephalosporins and penicillins belong to the beta-lactam class of antibiotics, which share a similar structure and mechanism of action. They inhibit bacterial cell wall synthesis by binding to specific proteins called penicillin-binding proteins (PBPs), leading to bacterial cell death. This shared mechanism of action makes cephalosporins and penicillins similar in their antibacterial effects.
On the other hand, macrolides, fluoroquinolones, and aminoglycosides are different classes of antibiotics with distinct structures and mechanisms of action. They work through different mechanisms to inhibit bacterial growth and have different spectrums of activity compared to beta-lactam antibiotics like cephalosporins and penicillins.

Correct Answer is D
Explanation
To calculate the milliliters per hour (mL/hr) for the IV infusion, you divide the total volume (in milliliters) by the total time (in hours).
In this case, the total volume is 1 liter, which is equal to 1000 milliliters, and the total time is 6 hours.
So, you divide 1000 mL by 6 hours:
1000 mL / 6 hours = 166.67 mL/hr
Rounding off, the nurse will program the IV infusion device to infuse at approximately 167 mL/hr.
Correct Answer is E
Explanation
Dependent edema refers to the accumulation of fluid in the dependent parts of the body, which are areas that are most affected by gravity when a person is in a supine or sitting position for an extended period. The sacrum, which is the triangular bone at the base of the spine, is one such dependent area. It is prone to developing edema when there is increased fluid retention in the body, as seen in the patient's weight gain.
To assess for dependent edema accurately, the nurse can gently press the skin over the sacral area with their fingers and observe the skin turgor or the return of the skin to its normal position after releasing the pressure. If there is edema, the skin may have reduced elasticity and take longer to return to its normal position (poor skin turgor).
While edema can occur in other dependent areas such as the feet, ankles, and lower legs, assessing skin turgor in these areas may not provide an accurate determination of dependent edema as they are located further away from the sacrum and may be influenced by other factors.
