Extract:
Question 1 of 5
The LPN is taking care of a 176-pound client who has recently been diagnosed with diabetes. The primary healthcare provider has written an order for Lantus (insulin glargine injection) 100 units/mL, using weight-based dosing of 0.2 units/kg per day. The LPN should prepare ___ units for administration.
Correct Answer: C
Rationale:
To find the answer, you must convert 176 pounds to kilograms. 2.2 pounds = 1 kg. You must divide 176 by 2.2, which equals 80 kg. The client is 80 kg, and they should receive 0.2 units for every kilogram they weigh, so 80 × 0.2 = 16 units.
Question 2 of 5
What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?
Correct Answer: C
Rationale: Administering dextrose concentrations above 10% through a peripheral IV can lead to phlebitis. It is safe to administer dextrose concentrations below 10% through a peripheral IV.
Question 3 of 5
The client taking lithium for bipolar disorder participated in a recreational game of basketball in the mental health unit gym. The client is now feeling nauseated and shaky, has blurred vision, and is finding it hard to stand. Considering this information, which action should be taken by the nurse?
Correct Answer: B
Rationale: The client is showing signs of lithium (Lithane) toxicity, especially apparent after high levels of physical activity. The HCP should be notified for a STAT lithium level and corrective action.
Question 4 of 5
The nurse working on the pediatric unit has scheduled medications to administer at this time. Which assessments should prompt the nurse to conclude that the prescribed medication should be withheld and the HCP immediately notified?
Correct Answer: C
Rationale: A: Dizziness and light-headedness are side effects of hydrocodone with acetaminophen (Vicodin), and the nurse may choose to withhold a scheduled dose. These are not potentially life-threatening or warranting an immediate call to the HCP. B: A rash is a side effect of acetaminophen (Tylenol). However, the rash is not potentially life-threatening or warranting an immediate call to the HCP. C: An adverse effect of clindamycin (Cleocin) is hypotension. A BP of 92/56 mm Hg is low for a 16-year-old. Normal BP for a 16-year-old male is 111/63 mm Hg to 136/90 mm Hg, depending on height percentile. The nurse should compare the previous BP readings with the current one to determine the degree of BP variation and then immediately notify the HCP because the BP can decrease further. D: Tiredness and drowsiness are side effects of phenobarbital (Luminal). However, these are expected. The nurse would not withhold phenobarbital unless there were additional neurological alterations that would warrant contacting the HCP.
Question 5 of 5
When administering intravenous electrolyte solution, the nurse should take which of the following precautions?
Correct Answer: C
Rationale: Preventing tissue infiltration is important to avoid tissue necrosis.
Choice A is incorrect because hypertonic solutions should be infused cautiously and checked with the RN if there is a concern.
Choice B is incorrect because potassium, mixed in the pharmacy per physician order, is mixed at a concentration no higher than 60 mEq/L.
