A nurse is preparing to administer lactated Ringer's 400 mL IV bolus to infuse over 3 hr. The drop factor of the manual IV tubing is 20 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["44"]
Calculate the flow rate in mL/hour: 400 mL / 3 hours = 133.33 mL/hour (approximately)
Convert the flow rate to mL/minute: 133.33 mL/hour / 60 minutes/hour = 2.22 mL/minute (approximately)
Calculate the drops per minute: 2.22 mL/minute 20 gtt/mL = 44.4 gtt/minute
Round to the nearest whole number: 44 gtt/minute

Correct Answer is C
Explanation
A. Hypertension and headache are not typical signs of hypermagnesemia. These symptoms are more commonly associated with conditions like hypertension or intracranial pressure.
B. Tachycardia and tachypnea are not characteristic of hypermagnesemia. In fact, hypermagnesemia typically causes bradycardia and hypoventilation due to the depressant effect of magnesium on the cardiovascular and respiratory systems.
C. Depressed deep tendon reflexes are a classic sign of hypermagnesemia. Magnesium sulfate acts as a central nervous system depressant, and elevated magnesium levels can impair neuromuscular function, leading to reduced reflexes.
D. Positive Trousseau's sign is indicative of hypocalcemia, not hypermagnesemia. It is a sign of low calcium levels, where a blood pressure cuff inflated above systolic pressure for 3 minutes causes muscle spasms in the hand and forearm.
Correct Answer is B
Explanation
A. Removing and applying the fixator for showers is not appropriate. The external fixator should not be removed by the nurse without proper medical guidance. Showers should be managed in a way that prevents the fixator from becoming wet or contaminated.
B. Documenting pin site assessment and care is essential for clients with external fixation. The nurse should regularly assess pin sites for signs of infection (e.g., redness, swelling, drainage) and ensure proper care is provided to prevent complications.
C. Encouraging the patient to lie prone several times per day may not be necessary or appropriate unless specifically ordered by the provider. The patient’s positioning should be based on comfort and the provider’s instructions to avoid strain on the injured limb.
D. Turning the patient every 3 hours is a general nursing practice for preventing pressure ulcers, but it is not specific to the care of a client with external fixation. The focus should be on protecting the fixator and ensuring the limb is properly supported.
