Extract:
Question 1 of 5
The client has an order for 0.45 mg Diltiazem. The medication vial has a concentration of 3 mg/mL. How many mL of the drug should be administered?
Correct Answer: A
Rationale: The correct calculation is 0.45 / 3 which equals 0.15 mL.
Question 2 of 5
An allergic reaction is classified as what type of pharmacological effect?
Correct Answer: C
Rationale: An allergic reaction is considered an adverse effect, as it is unintended and requires treatment. A side effect is also undesired but is somewhat expected, and a side effect does not require intervention.
Question 3 of 5
When caring for a client with a possible diagnosis of placenta previa, which of the following admission procedures should the nurse omit?
Correct Answer: B
Rationale: An enema risks dislodging the placenta in placenta previa, potentially causing severe bleeding, and should be avoided.
Question 4 of 5
The LPN is about to give 100 mg Lopressor (metoprolol) to a client. Before administering the drug, he takes the patient's vitals, which are as follows: Pulse: 58, Blood Pressure: 90/62, Respirations: 18/minute. What action should the LPN take?
Correct Answer: D
Rationale: Lopressor is given to treat hypertension, and a pulse of 58 and a blood pressure of 90/62 are considered low.
To prevent the client from bottoming out, the drug should be held and the findings reported to the RN, who should consult with the attending physician. LPNs should never adjust client dosing, as that is outside of their scope of practice.
Question 5 of 5
Following a THR, the client asks the nurse, “Why am I receiving enoxaparin? With my last hip surgery, I was given a heparin injection.†What is the nurse's best response?
Correct Answer: C
Rationale: A: The cost of enoxaparin is more than twice the cost of the equivalent dose of heparin per injection. Both are available in prefilled syringes for subcutaneous injection. B: Both enoxaparin and heparin increase aPTT, which affects clotting. C: Because enoxaparin is more specific in inhibiting active factor X, the response is more stable, and the effect is two to four times longer than that of heparin. D: Enoxaparin is only administered subcutaneously. Heparin can be administered both subcutaneously and intravenously.
