Question 1 of 5
The following are anticoagulants that do not require monitoring of INR:
Correct Answer: D
Rationale: These are direct oral anticoagulants (DOACs), which do not require regular INR monitoring.
Question 2 of 5
An adolescent client will receive Depo-Provera as a method of birth control. She asks the nurse how long the drug will be effective. What is the best response by the nurse?
Correct Answer: D
Rationale: Depo-Provera, a progestin injection, provides contraception by inhibiting ovulation for 3 months , requiring re-administration every 12 weeks. This duration is based on its pharmacokinetic profile, ensuring reliable hormone levels. Two months underestimates, risking unprotected gaps. Six months or 1 year overestimate, reducing efficacy mid-cycle. The nurse's accurate response (D) educates the client on timing, ensuring adherence and preventing unintended pregnancy, aligning with clinical standards for injectable contraceptives.
Question 3 of 5
A patient has been taking digoxin at home but took an accidental overdose and has developed toxicity. The patient has been admitted to the telemetry unit, where the physician has ordered
Correct Answer: B
Rationale: The correct response is to inform the patient that the medication, likely an antiarrhythmic agent such as digoxin immune fab (Digibind), helps to convert the irregular heart rhythm caused by digoxin toxicity to a more normal rhythm. This explanation provides a clear understanding of why the medication is being administered in cases of digoxin toxicity. It is important for the nurse to educate the patient about the purpose of the medication and how it will help manage the symptoms of digoxin toxicity.
Question 4 of 5
A patient with extremely high blood pressure (BP) is in the emergency department. The physician will order therapy with nitroglycerin to manage the patient™s BP. Which form of nitroglycerin is most appropriate?
Correct Answer: D
Rationale: In the emergency management of a patient with extremely high blood pressure, intravenous (IV) administration of nitroglycerin is the most appropriate form of delivery. IV infusion provides rapid and precise control of blood pressure by allowing the medication to take effect quickly and be titrated to the desired blood pressure level. This route of administration is crucial in acute settings like the emergency department, where immediate blood pressure management is needed. Other forms of nitroglycerin, such as sublingual spray, transdermal patch, or oral capsule, may not provide the rapid onset of action required in this critical situation.
Question 5 of 5
The nurse administering the phosphodiesterase inhibitor milrinone (Primacor) recognizes that this drug will have a positive inotropic effect. Which result reflects this effect?
Correct Answer: C
Rationale: Milrinone is a phosphodiesterase inhibitor that works by increasing the levels of cyclic adenosine monophosphate (cAMP) within cardiac myocytes. This leads to enhanced calcium influx into the cells, ultimately resulting in increased force of cardiac contractions (positive inotropic effect). This increased contractility helps improve cardiac output without necessarily increasing heart rate or affecting blood vessel dilation.
