How many mg should the nurse administer per dose to a child weighing 44 lbs if the prescribed dose is 15 mg/kg every 12 hours?
- A. 150 mg
- B. 200 mg
- C. 300 mg
- D. 350 mg
- E. 400 mg
Correct Answer: C
Rationale: To calculate the correct dose, we first convert the child's weight from pounds to kilograms (44 lbs ÷ 2.2 = 20 kg). Then, we multiply the weight by the prescribed dose (20 kg x 15 mg/kg = 300 mg). Therefore, the nurse should administer 300 mg per dose. Choice A is too low, choices B and D are higher than the correct answer, and choice E is significantly higher, exceeding the calculated dose.

Which of the following statements should the nurse include in the teaching about the new medication? Select the 2 statements the nurse should include in the teaching.
- A. You should take medication with dairy products
- B. This medication may cause constipation.
- C. It is common to experience headache or blurred vision while taking this medication.
- D. You should avoid the sun while taking this medication.
Correct Answer: B, D
Rationale: The correct answers are B and D. Statement B is important as it informs the patient about a potential side effect (constipation) of the medication, promoting awareness and preparedness. Statement D is crucial as some medications can increase sensitivity to sunlight, leading to adverse reactions like sunburn. Choices A, C, and the remaining options are incorrect as taking medication with dairy products can interfere with absorption, experiencing headache or blurred vision is not common for all medications, and not all medications require sun avoidance.
Which of the following actions should the nurse take when observing infiltration of fluid into the tissue surrounding an IV insertion site?
- A. Flush the IV catheter
- B. Apply pressure to the IV site
- C. Elevate the extremity
- D. Slow the infusion rate
Correct Answer: C
Rationale: The correct answer is C: Elevate the extremity. Elevating the extremity helps to reduce swelling and minimize further infiltration of fluid into the surrounding tissue. By elevating the extremity, gravity assists in draining the fluid away from the IV site. This action helps to prevent tissue damage and potential complications.
Incorrect choices:
A: Flushing the IV catheter will not address the infiltration and may worsen the situation.
B: Applying pressure to the IV site can further damage the tissue and exacerbate the infiltration.
D: Slowing the infusion rate may not prevent further infiltration and does not address the existing issue effectively.
A nurse is preparing to administer heparin subcutaneously to a client. Which of the following actions should the nurse plan to take?
- A. Administer the medication outside the 5 cm (2 in) radius of the umbilicus.
- B. Aspirate for blood return before injecting.
- C. Rub vigorously after the injection to promote absorption.
- D. Place a pressure dressing on the injection site to prevent bleeding.
Correct Answer: A
Rationale: The correct answer is A: Administer the medication outside the 5 cm (2 in) radius of the umbilicus. This is because injecting heparin near the umbilicus can lead to bruising or hematoma formation. Subcutaneous injections are generally given in the fatty tissue of the abdomen, but it is important to avoid the area around the umbilicus to prevent discomfort and complications. Aspiration for blood return (B) is not necessary for subcutaneous injections as they are not typically administered into a blood vessel. Rubbing vigorously after the injection (C) is not recommended as it can cause tissue damage. Placing a pressure dressing on the injection site (D) is also unnecessary for subcutaneous injections.
How many mL/h should the nurse set the IV infusion pump to deliver half the total volume of lactated Ringer's (4,080 mL) in the first 8 hours?
- A. 200 mL/h
- B. 225 mL/h
- C. 250 mL/h
- D. 255 mL/h
- E. 275 mL/h
Correct Answer: D
Rationale: The correct answer is D: 255 mL/h. To deliver half of 4,080 mL in 8 hours, you need to administer 2,040 mL in 8 hours. To calculate the infusion rate, divide the total volume by the total time: 2,040 mL ÷ 8 hours = 255 mL/h. This rate ensures half of the total volume is infused within the specified time frame.
Choice A (200 mL/h) is too slow, as it would not deliver half the volume in 8 hours. Choices B, C, and E exceed the required rate and would deliver more than half the volume in 8 hours.
Which of the following findings should indicate to the nurse that a client with myasthenia gravis taking neostigmine is experiencing an adverse effect?
- A. Tachycardia
- B. Oliguria
- C. Xerostomia
- D. Miosis
Correct Answer: D
Rationale: The correct answer is D: Miosis. Neostigmine is a cholinesterase inhibitor used to treat myasthenia gravis. Miosis, or excessive constriction of the pupil, is a sign of cholinergic crisis which can occur due to neostigmine overdose. This adverse effect indicates excessive stimulation of the parasympathetic nervous system, leading to symptoms such as increased salivation, bronchoconstriction, and miosis. Tachycardia (A) is not typically associated with neostigmine use, oliguria (B) is not a common adverse effect, and xerostomia (C) is the opposite of the expected effect of increased salivation due to cholinergic stimulation.
