Extract:
Question 1 of 5
A nurse is caring for a client who has schizophrenia and is experiencing hallucinations. The provider prescribes chlorpromazine 50 mg IM every 4 hr as needed. Available is chlorpromazine injection 25 mg/mL. How many mL should the nurse administer per dose?
Correct Answer: A
Rationale: The correct answer is A: 2 mL.
To calculate the correct dose, divide the prescribed dose (50 mg) by the concentration of the medication (25 mg/mL). This gives you 2 mL, which is the amount the nurse should administer per dose.
Choices B to G are incorrect as they do not reflect the correct calculation based on the prescribed dose and medication concentration. In medication calculations, it is crucial to accurately convert the prescribed dose to the correct volume to administer.
Question 2 of 5
A nurse is providing teaching for a client who has a new prescription for alprazolam to treat insomnia. Which of the following instructions should the nurse include?
Correct Answer: A
Rationale: The correct answer is A: Avoid activities that require alertness, such as driving. Alprazolam is a sedative medication that can cause drowsiness and impair cognitive function. Instructing the client to avoid activities requiring alertness, such as driving, helps prevent accidents. Monitoring for peripheral edema (
B) is not relevant to alprazolam use. Taking the medication with a high-fat meal (
C) can delay its onset of action. Taking the medication every night before sleep (
D) is correct, but the key instruction regarding alertness is more crucial for safety.
Question 3 of 5
A nurse is caring for a client who requires a medication that is packaged in a single dose glass ampule. Which of the following techniques should the nurse use when opening the glass ampule?
Correct Answer: A
Rationale: The correct answer is A because tapping the top of the ampule helps dislodge any liquid that may be adhered to the top, reducing the risk of spillage. Placing a sterile gauze pad around the neck provides a barrier to prevent injury from glass shards. Breaking off the top by bending it toward the body minimizes the risk of glass particles falling into the medication.
Choice B is incorrect because tapping the bottom can cause the ampule to shatter, leading to injury. Breaking off the bottom with a forward motion can result in glass shards contaminating the medication.
Choices C and D are incorrect because breaking off the neck of the ampule in a downward motion or to the right side can increase the risk of glass particles falling into the medication or causing injury to the nurse.
Overall, following the steps outlined in option A ensures safe and effective opening of the glass ampule while minimizing the risk of contamination and injury.
Question 4 of 5
A nurse is teaching a client who has bipolar disorder and a prescription for lithium to recognize the manifestations of toxicity. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: A
Rationale: The correct answer is A: Vomiting is an indication of toxicity. Lithium toxicity can manifest with gastrointestinal symptoms like vomiting. This statement shows an understanding of a key symptom of lithium toxicity.
Incorrect choices:
B: Loss of appetite is a common side effect of lithium, not necessarily a sign of toxicity.
C: Headaches are not specific to lithium toxicity and may not be an early sign.
D: Increased flatulence is not a typical manifestation of lithium toxicity.
Question 5 of 5
A nurse is caring for a client who is to receive liquid medications via a gastrostomy tube. The client is prescribed phenytoin 250 mg. The amount available is phenytoin oral solution 25 mg/5 mL. How many mL should the nurse administer per dose?
Correct Answer: A
Rationale: The correct answer is A: 50 mL.
To calculate the dose, use the formula: Desired dose/Available dose = Volume to be given. In this case, 250 mg (desired dose) divided by 25 mg/5 mL (available dose) equals 50 mL.
Therefore, the nurse should administer 50 mL per dose.
Choice B and other options are incorrect because they do not follow the correct calculation method. It is essential to accurately convert the prescribed dose to the available concentration to determine the correct volume to administer. In this scenario, the correct answer is 50 mL based on the calculation using the formula provided.
