Question 1 of 5
Meperidine hydrochloride (Demerol) is given to a client who is experiencing post-operative pain. Which of the following are the side effects of the medication, except?
Correct Answer: A
Rationale: Meperidine hydrochloride (Demerol) is an opioid analgesic used for pain relief, but it is known to cause side effects. Tremors are not a common side effect associated with Meperidine. Diarrhea, sweating, and dizziness are commonly reported side effects of this medication. Tremors are more commonly associated with stimulant medications or conditions like anxiety or certain neurological disorders.
Question 2 of 5
A nurse working in an obstetric practice should consider which fact when discussing medication use with pregnant patients?
Correct Answer: A
Rationale: Pregnancy boosts lung perfusion, increasing inhaled drug absorption (e.g., anesthetics), a pharmacokinetic shift to note. Excretion may slow later, but not universally. Oral absorption isn't broadly reduced-GI changes vary. Avoiding all drugs is impractical-some conditions need treatment. Inhaled absorption informs safe use.
Question 3 of 5
Which of the following should the nurse include when providing dietary teaching for the patient receiving warfarin (Coumadin) therapy?
Correct Answer: A
Rationale: The nurse should include the instruction to avoid drinking large amounts of green tea when providing dietary teaching for a patient receiving warfarin therapy. Green tea is high in vitamin K, which can interfere with the effectiveness of warfarin, an anticoagulant medication. Maintaining a consistent intake of vitamin K is important for patients on warfarin in order to keep their INR (International Normalized Ratio) levels stable. It is not necessary to avoid all sources of vitamin K, but rather to keep intake consistent and moderate. Drinking large amounts of green tea, which is high in vitamin K, can potentially impact the patient's INR levels and increase the risk of bleeding or clotting issues.
Question 4 of 5
A patient is receiving heparin therapy as part of the treatment for a pulmonary embolism. The nurse monitors the results of which laboratory test to check the drug™s effectiveness?
Correct Answer: B
Rationale: The nurse monitors the activated partial thromboplastin time (aPTT) to check the effectiveness of heparin therapy in a patient with a pulmonary embolism. Heparin works by inhibiting the clotting cascade, specifically by potentiating the activity of antithrombin III, which inactivates thrombin and factor Xa. Monitoring the aPTT helps determine the appropriate dosage of heparin to maintain therapeutic levels of anticoagulation and prevent clot formation without increasing the risk of bleeding. The desired therapeutic range for aPTT when a patient is on heparin therapy is usually 1.5 to 2.5 times the control value. Monitoring aPTT levels regularly helps ensure that the patient is receiving the correct dose of heparin for effective treatment of the pulmonary embolism.
Question 5 of 5
The nurse completes medication education for the client receiving antihistamines. The nurse evaluates that learning has occurred when the client makes which statement?
Correct Answer: D
Rationale: Antihistamines, particularly first-generation ones (e.g., diphenhydramine), block H1 receptors but cross the blood-brain barrier, causing sedation. The statement 'This medication could make me very sleepy' shows the client understands this key side effect, indicating effective education. Alcohol exacerbates sedation, so that's incorrect. Increased fluids aren't specifically required unless addressing dry mouth, a secondary issue. OTC status doesn't guarantee safety, a common misconception. The nurse evaluates learning by the client's recognition of drowsiness, critical for safety (e.g., avoiding driving), making choice D the best evidence of comprehension.
