The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?
(Enter numerical value only.)
The Correct Answer is ["450"]
- To calculate the infusion rate, use the formula:
(mL of solution / grams of drug) x (grams ordered / minutes to infuse) x 60
- In this case, the formula becomes: (500 mL / 20 g) x (6 g / 20 min) x 60
- Simplify and solve: (25 mL / g) x (0.3 g / min) x 60
- The answer is 450 mL/hour
- The nurse should set the infusion pump at 450 mL/hour

Correct Answer is A
Explanation
Encourage voiding:A boggy uterus that is displaced above and to the right of the umbilicus often indicates that the bladder may be distended, which can push the uterus out of its normal position and prevent it from contracting properly. Encouraging the client to void can help to reduce bladder distension and allow the uterus to return to its normal position and firm up.
Notify healthcare provider:While this may ultimately be necessary if the problem persists or other complications are noted, the immediate action should be to address the most common cause of uterine displacement, which is bladder distension.
Inspect the perineal pad:
Checking the perineal pad can give clues about the amount of lochia (postpartum vaginal discharge). However, in this scenario, the priority lies in addressing the potential uterine atony.
Monitor vital signs:
While it's important to monitor vital signs, especially in postpartum clients, the priority here is recognizing and managing the potential uterine atony.
Correct Answer is A
Explanation
A. Use a fingertip to palpate the inguinal canal for a weakening or indentation:
This is a reasonable next step in assessing for undescended testes. Palpating the inguinal canal can help determine if the testes are located in the inguinal area.
B.Measure the size of the scrotal sac for length and width:
While scrotal size can be relevant in some contexts, it may not provide direct information about the presence or absence of the testes. Palpation or other methods are more specific for this purpose.
C. Perform transillumination of the scrotal sac to visualize shadows of the testes:
Transillumination involves shining light through tissues to detect structures. However, in the case of evaluating the presence of testes, palpation is usually a more direct and accurate method.
D. Observe the urethral opening on the surface of the penis when the newborn voids:
This option is unrelated to assessing the presence of testes. Observing the urethral opening is more relevant for assessing the anatomy of the penis.
