The withdrawal syndrome is a combination of certain drug-specific symptoms that occur on sudden discontinuation of the drug. This syndrome is associated with:
Correct Answer: D

Question 2 of 5
Nonselective adrenergic blocking agents have a variety of therapeutic uses. Which agent is used for the treatment of heart failure?
Correct Answer: A
Rationale: Carvedilol is available orally and is used to treat hypertension as well as congestive heart failure and left ventricular dysfunction after a myocardial infarction. Sotalol is a nonselective beta-adrenergic blocking agent used to treat potentially life-threatening ventricular arrhythmias and to maintain normal sinus rhythm in patients with atrial fibrillation or flutter. Propranolol is a nonselective beta-adrenergic blocking agent used for treatment of hypertension, angina, idiopathic hypertrophic subaortic stenosis (IHSS) induced palpitations, angina and syncope, some cardiac arrhythmias induced by catecholamines or digoxin, pheochromocytoma; prevention of reinfarction after myocardial infarction; prophylaxis for migraine headache (which may be caused by vasodilation and is relieved by vasoconstriction, although the exact action is not clearly understood); prevention of stage fright (which is a sympathetic stress reaction to a particular situation); and treatment of essential tremors. Tamsulosin is used to treat benign prostatic hyperplasia and is an alpha1-selective adrenergic blocking agent.
Question 3 of 5
The nurse is reviewing the plan of care for a patient receiving enteral therapy. What is the most common complication of enteral therapy?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Some drugs are excreted into bile and delivered to the intestines. Prior to elimination from the body, the drug may be absorbed. This process is known as:
Correct Answer: C
Rationale: Enterohepatic cycling refers to the process where drugs excreted into bile are delivered to the intestines and then reabsorbed into the bloodstream. This recycling can prolong the drug's presence in the body and its therapeutic effects. Hepatic clearance and total clearance refer to the liver's ability to remove drugs from the bloodstream, while the first-pass effect involves the metabolism of drugs before they reach systemic circulation. Enterohepatic cycling is a unique mechanism that impacts drug pharmacokinetics.
Question 5 of 5
Rho(D) immune globulin (RhoGAM) is given to a pregnant woman after delivery and the nurse is giving information to the patient about the indication of the medication. The nurse determines that the patient understands the purpose of the medication if the patient tells that it will protect her baby from which of the following?
Correct Answer: D
Rationale: Rho(D) immune globulin (RhoGAM) is administered to Rh-negative mothers to prevent Rh incompatibility in future pregnancies. It works by preventing the mother's immune system from developing antibodies against Rh-positive fetal blood cells, which could harm subsequent Rh-positive babies. Pernicious anemia and German measles are unrelated to RhoGAM. The medication does not affect the baby's blood type but prevents the mother's immune response. Therefore, Rh incompatibility is the correct answer.
