Question 1 of 5
A patient has been receiving intravenous heparin. When laboratory tests are drawn, the nurse has difficulty
Correct Answer: C
Rationale: Protamine sulfate is the specific antidote for heparin, which is used to reverse the effects of heparin in cases of bleeding or elevated PTT/aPTT levels. It works by binding to heparin, neutralizing its anticoagulant activity. Therefore, in this scenario where the patient is experiencing bloody stools, abdominal pain, and has elevated PTT/aPTT levels, the appropriate action for the nurse to take is to obtain an order for protamine sulfate to reverse the effects of heparin. This will help normalize the patient's coagulation profile and manage any bleeding complications associated with heparin therapy.

Question 3 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 4 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.
Question 5 of 5
A 60-year-old woman has ulcerative colitis resistant to aminosalicylates and topical corticosteroids. It is decided to treat her with systemic corticosteroids. Which of the following is not a likely complication of the treatment?
Correct Answer: B
Rationale: Systemic corticosteroids (e.g., prednisone) for ulcerative colitis cause side effects. Osteoporosis results from reduced bone formation over time. Diabetes stems from glucocorticoid-induced hyperglycemia. Hypertension occurs via sodium retention and vasoconstriction. Mood changes are common due to CNS effects. Weight loss isn't typical; corticosteroids cause weight gain from increased appetite and fat redistribution, making it the exception. This reflects their metabolic impact, requiring monitoring in chronic use.
