The healthcare provider prescribes heparin 3 units/kg IV push for a client who weighs 175 pounds. The vial is labeled, "100 units/mL." How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth).
The Correct Answer is ["2.4"]
Convert the client's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds.
Calculate the total number of units of heparin needed by multiplying the client's weight in kilograms by the prescribed dosage (3 units/kg).
Determine the volume of heparin to administer by dividing the total number of units needed by the concentration of the vial (100 units/mL).
The calculation:
Client's weight in kg: 175 pounds / 2.2 = 79.55 kg (rounded to the nearest tenth)
Total units of heparin needed: 79.55 kg 3 units/kg = 238.65 units
Volume of heparin to administer: 238.65 units / 100 units/mL = 2.39 mL
Therefore, the nurse should administer 2.4 mL of heparin. (rounded to the nearest tenth)

Correct Answer is ["A","B","D","E","G"]
Explanation
A. Prepare to prevent respiratory or cardiac arrest: The client's decreased level of consciousness and respiratory rate of 10 breaths/minute indicate a potential risk for respiratory or cardiac arrest. Immediate measures to maintain airway patency and support ventilation may be necessary.
B. Stop infusion of magnesium: The client's decreased level of consciousness and absent deep tendon reflexes (DTR) bilaterally are signs of magnesium toxicity. Stopping the infusion of magnesium sulfate is essential to prevent further complications.
C. Increasing IV fluids is not a priority in management of magnesium toxicity.
D. Obtain serum magnesium level: With signs of magnesium toxicity, obtaining a serum magnesium level is necessary to confirm the diagnosis and guide further management.
E. Administer oxygen: The client's oxygen saturation of 93% on room air indicates hypoxemia.
Administering oxygen via nasal cannula to maintain oxygen saturation greater than 96% helps prevent further respiratory compromise.
F. Obtaining blood pressure is not a priority.
G. Administer calcium gluconate: Calcium gluconate is the antidote for magnesium toxicity.
Since the client is showing signs of magnesium toxicity (decreased level of consciousness and absent DTRs), administering calcium gluconate is necessary to counteract the effects of magnesium
H. Caesarian delivery is not part of management for magnesium toicity.
Correct Answer is C
Explanation
A. Monitor and document strict intake and output: While monitoring intake and output is
important in managing fluid balance, it may not directly address the potential complications associated with hyperkalemia and hyperglycemia.
B. Assess the serum potassium level every 4 hours: While monitoring potassium levels is important, obtaining a 12-lead electrocardiogram provides immediate information about the cardiac effects of hyperkalemia, which can be life-threatening.
C. Obtain a 12-lead electrocardiogram daily: Hyperkalemia can lead to serious cardiac arrhythmias, including bradycardia, heart block, and ventricular fibrillation. Daily
electrocardiograms can help detect these changes early.
D. Evaluate glucose levels before and after meals: While monitoring glucose levels is important, the immediate concern in this scenario is the potential cardiac effects of hyperkalemia.
