Extract:
Question 1 of 5
A nurse is preparing to administer amikacin 5 mg/kg IM to a client who weighs 110 lb. Available is amikacin injection 250 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if applicable. Do not use a trailing zero.)
Correct Answer: 1
Rationale:
To answer this question, you need to perform the following steps: Convert the client's weight from pounds to kilograms by dividing by 2.2. 110 lb / 2.2 = 50 kg. Calculate the dose of amikacin in milligrams by multiplying the client's weight by the prescribed dose per kilogram. 50 kg × 5 mg/kg = 250 mg. Calculate the volume of amikacin in milliliters by dividing the dose in milligrams by the concentration of the injection. 250 mg / 250 mg/mL = 1 mL. Round the answer to the nearest whole number. The nurse should administer 1 mL of amikacin IM to the client.
Question 2 of 5
A nurse is collecting data from a client who has been taking diazepam several times per day but recently ran out of the medication. Which of the following findings should the nurse recognize as a manifestation of withdrawal from diazepam?
Correct Answer: D
Rationale: Anorexia is not typically associated with benzodiazepine withdrawal. Hypotension is not a common withdrawal symptom of diazepam. Drowsiness is more likely a side effect of benzodiazepine use rather than withdrawal. Tremors are a common manifestation of benzodiazepine withdrawal.
Question 3 of 5
A nurse is reinforcing discharge teaching with a client who has a new diagnosis of type 2 diabetes mellitus and a prescription for exenatide. Which of the following instructions should the nurse include in the teaching?
Correct Answer: C
Rationale: Exenatide is typically administered before meals, not necessarily at bedtime. Discarding medication after a specified time is a general guideline, but it is not specific to exenatide. Exenatide is typically injected into the subcutaneous tissue of the abdomen to enhance absorption. While monitoring for adverse effects is important, muscle pain is not a commonly reported side effect of exenatide.
Question 4 of 5
A nurse is preparing to administer enoxaparin subcutaneously to a client using a prefilled syringe. The nurse should plan to use which of the following techniques when administering this medication?
Correct Answer: B
Rationale: The air bubble helps to ensure that the entire dose of medication is delivered and prevents bleeding from the injection site. The nurse should plan to inject enoxaparin subcutaneously into abdominal tissue using a prefilled syringe without expelling the air bubble or aspirating prior to injecting the medication. Aspiration is not recommended because it may cause hematoma formation. Massaging the site is generally not recommended after enoxaparin injections to avoid bruising or hematoma formation.
Question 5 of 5
A nurse is collecting data from a client who is taking aspirin. Which of the following findings should the nurse report to the provider?
Correct Answer: D
Rationale: Headache - Headache is a common side effect of aspirin and is not typically a cause for concern. BP 120/70 mm Hg - This blood pressure reading is within the normal range and is not a cause for concern related to aspirin. Hct 43% - Elevated hematocrit is not an adverse effect of aspirin. Rhinitis is a sign of hypersensitivity to aspirin and can indicate a risk of developing more severe reactions, such as bronchospasm or anaphylaxis. The nurse should report this finding to the provider and stop the medication.
