A client is to receive Acyclovir 350 mg IV. You have available a 500 mg vial. Package directions tell you to reconstitute with 15 mL of sterile water. After withdrawing the required dose, further dilute in 100 mL of IV fluid to run over 1 hour. Calculate the rate to set the IV pump. (Round to the nearest tenth).
The Correct Answer is ["100.0"]
First, reconstitution only helps us get the correct dose, but the IV pump rate depends on the final volume and time.
The medication is reconstituted and the prescribed 350 mg is withdrawn from the vial. That dose is then added to 100 mL of IV fluid to infuse over 1 hour.
For IV pump settings, we use:
Rate (mL/hr) = Total volume to infuse ÷ Time in hours
Rate = 100 mL ÷ 1 hour
Rate = 100 mL/hr
Correct answer: 100.0 mL/hr

Correct Answer is B
Explanation
A. local funeral home morgues. Local funeral homes lack the capacity and specialized radiation shielding required to handle a large volume of contaminated remains. Using multiple small sites increases the risk of secondary environmental contamination and complicates the tracking of victims. Centralized management is necessary during a mass casualty event involving hazardous radiological materials.
B. refrigerated trucks. A nuclear detonation results in a mass fatality incident that quickly overwhelms existing hospital and municipal morgue facilities. Refrigerated trucks provide the necessary temporary storage to prevent decomposition while forensic identification and radiological decontamination are performed. This is a standard emergency management strategy for managing surge capacity in catastrophic events.
C. mass graves. Mass graves are a last resort that hinders the individual identification and dignified return of remains to family members. This method can also lead to environmental contamination of groundwater if not properly managed. Public health protocols prioritize temporary refrigeration over permanent mass internment to maintain forensic and social standards.
D. the hospital morgue. Hospital morgues are designed for standard daily operations and cannot accommodate the sudden influx of hundreds or thousands of bodies. Overfilling the hospital morgue creates a biohazard risk and interferes with the facility's ability to function. Disaster response plans require the activation of external, temporary morgue solutions to handle the overflow.
Correct Answer is A
Explanation
A. Heavy lifting. Activities that increase intrathoracic or intra-abdominal pressure can cause a spike in intracranial pressure, risking a cerebrospinal fluid leak at the surgical site. Straining can compromise the integrity of the nasal packing or the graft used to close the sella turcica. Clients must avoid lifting objects over 5 to 10 pounds for several weeks postoperatively to ensure proper healing.
B. Climbing stairs. Stair climbing is generally permitted as long as the client avoids overexertion and maintains a steady pace. It does not typically cause the significant increase in pressure associated with the Valsalva maneuver or heavy lifting. Patients are encouraged to ambulate slowly to prevent postoperative complications like deep vein thrombosis while remaining cautious of their balance.
C. Breathing exercises. Deep breathing and use of an incentive spirometer are encouraged to prevent atelectasis and pneumonia after surgery. However, the client is strictly taught to avoid coughing, sneezing, or blowing their nose, as these actions create high pressure in the nasal cavity. If a sneeze is unavoidable, the client should keep their mouth open to dissipate the pressure.
D. Sexual intercourse. While high-intensity physical exertion should be avoided, sexual activity is not specifically restricted unless it involves positions or straining that increase intracranial pressure. The primary focus of postoperative education is the avoidance of activities that directly stress the surgical site in the nasopharynx. Standard discharge instructions prioritize the prevention of straining over a total restriction of sexual activity.
