A nurse is caring for a client ordered ceftazidime 1g IM every 6 hours. The drug comes in a vial with a powder which is reconstituted with 3mL of sterile water for a final concentration of 280 mg/mL. How many mi. will be drawn into the syringe for the dose ordered? Do not use leading zero (Round to the tenth)
The Correct Answer is ["3.6"]
Given:
Desired dose: Ceftazidime 1 g IM every 6 hours
Available concentration: Ceftazidime 280 mg/mL
To find:
Volume to administer (in mL)
Step 1: Convert desired dose to milligrams
1 gram (g) is equal to 1000 milligrams (mg).
Multiply by 1000:
Desired dose (mg) = Desired dose (g) x 1000
Desired dose (mg) = 1 g x 1000 = 1000 mg
Step 2: Set up the proportion
We can use the following proportion to solve the problem:
(Desired dose) / (Available concentration) = Volume to administer
Step 3: Substitute the values
Plugging in the given values, we get:
(1000 mg) / (280 mg/mL) = Volume to administer
Step 4: Simplify
To simplify, we can invert the denominator and multiply:
(1000 mg) x (1 mL / 280 mg) = Volume to administer
The "mg" units cancel out, leaving us with:
(1000 x 1 mL) / 280 = Volume to administer
Step 5: Calculate
Performing the multiplication and division, we get:
1000 mL / 280 = Volume to administer
3.57 mL ≈ Volume to administer
Step 6: Round to the nearest tenth
3.6mL

Correct Answer is A
Explanation
A) Practicing effleurage on the abdomen:
It is an excellent non-pharmacological pain management technique that can help distract the mother, reduce anxiety, and alleviate some of the discomfort associated with early labor. It also promotes relaxation and can help manage early labor pain effectively without the need for medications. This technique is easy to perform and can be done by the nurse or the partner, providing emotional support along with pain relief.
B) Beginning epidural anesthesia:
Epidural anesthesia is typically not initiated in the early phase of labor unless there is a specific indication or a desire for significant pain relief early in the process. An epidural is more commonly offered in the later stages of labor, when the pain is more intense and the cervix is further dilated. Starting an epidural too early could expose the mother to unnecessary risks and is generally not recommended unless it's requested or deemed medically necessary.
C) Using an opioid antagonist, such as Butorphanol:
Opioids, including Butorphanol, can have side effects such as drowsiness, nausea, and respiratory depression in both the mother and fetus. These medications are more commonly used in later stages of labor or when more potent pain relief is required. Additionally, opioid antagonists like Butorphanol may not be the best choice for a client who is experiencing anxiety and mild to moderate pain in the early phase, as they may not provide the relaxation and coping support that non-pharmacological methods like effleurage offer.
D) Immersing the client in hot water in a pool or Jacuzzi:
While immersion in water can be a helpful method of pain relief, especially during labor, it is generally recommended in the later stages of labor or when the cervix is dilated enough for water immersion to be safely utilized. Immersion in hot water may not be appropriate for all patients and could potentially lead to risks like overheating or changes in blood pressure. Additionally, the early phase of labor often involves less intense pain, and less invasive methods like effleurage are usually preferred first to manage discomfort and reduce anxiety.
Correct Answer is ["D","E","I","K"]
Explanation
The newborn's assessment findings that require follow-up:
Temperature 35.7°C (96.3°F) at 2200:
Hypothermia in newborns can lead to cold stress, which increases the risk of respiratory distress and hypoglycemia. The newborn’s temperature should be closely monitored, and warming measures should be initiated to prevent further complications.
Respiratory rate 68/min at 2200:
A respiratory rate above 60 breaths per minute in a newborn is considered tachypnea and can indicate respiratory distress or underlying conditions such as infection. The newborn should be further evaluated to determine the cause of the tachypnea and to ensure proper oxygenation.
Sternal retractions at 2200:
Sternal retractions suggest that the newborn is experiencing increased work of breathing, which is a key sign of respiratory distress. This requires immediate evaluation to assess the severity and identify potential causes, such as respiratory infections or inadequate ventilation.
Coarse rhonchi in bilateral lung fields at 2200:
The presence of coarse rhonchi indicates abnormal breath sounds, often related to fluid retention or infection in the lungs. This finding requires further assessment and possibly interventions to clear the airway and support respiratory function.
