The nurse has prepared a pain injection for a patient but was called to check on another patient. When asked to give the medication what action by the new nurse is best?

Correct Answer: A

Rationale: Because the nurse who administers the medication is responsible for any errors related to it, nurses administer only the medications they prepare. You cannot delegate preparation of medication to another person and then administer the medication to the patient. The right medication cannot be verified by the new nurse; do not violate the six rights. Do not administer the medication even one time. Do not administer the medication regardless of the pain rating. Avoiding the issue is not appropriate or safe.

Correct Answer: B

Rationale: Before going to the patient's room, compare the patient's name and name of medication on the label of prepared drugs with MAR for the second accuracy check. Selecting the correct medication from the stock supply, unit-dose drawer, or automated dispensing system (ADS) is the first check. The third accuracy check is comparing names of medications on labels with MAR at the patient's bedside. Checking the orders is not one of the three accuracy checks but should be done if there is any confusion about an order.

Correct Answer: D

Rationale: Dose = 22.4 kg × 24 mg/kg = 537.6 mg. Volume = 537.6 mg ÷ 50 mg/mL = 10.752 mL, rounded to 10.8 mL (one decimal place).

Correct Answer: B

Rationale: A large myocardial infarction impairs heart pumping, leading to cardiogenic shock due to inadequate cardiac output.

Correct Answer: D

Rationale: Only pharmacists can alter prescription labels legally. Staff, administrators, or residents altering labels compromises safety and legality.
