Pharmacology ATI Practice Exam 1 Questions
Question 1 of 5
This is an act to promote and ensure the production of an adequate supply, distribution, use and acceptance of the drug identified by their generic names is the:
Correct Answer: C
Rationale: Republic Act 6675, known as the Generics Act of 1988, is the act in the Philippines that promotes and ensures the production of an adequate supply, distribution, use, and acceptance of drugs identified by their generic names. The main goal of this act is to make quality generic medicines more accessible and affordable to the public. By encouraging the use of generic drugs, R.A 6675 aims to provide Filipinos with more affordable options for their healthcare needs while maintaining the quality and effectiveness of the medications. This act helps promote transparency in drug pricing and provides regulations to ensure the safety and efficacy of generic medicines in the country.
Question 2 of 5
A patient has been receiving intravenous heparin. When laboratory tests are drawn, the nurse has difficulty
Correct Answer: A
Rationale: The patient is displaying signs and symptoms that are suggestive of potential heparin-induced thrombocytopenia (HIT), a serious adverse effect of heparin therapy. Bloody stools and abdominal pain can indicate gastrointestinal bleeding, which can occur as a complication of heparin therapy. Elevated partial thromboplastin time (PTT) and activated partial thromboplastin time (aPTT) can also be seen in the setting of HIT.
Question 3 of 5
A patient receiving erythropoietin-stimulating drug has the following laboratory values: hemoglobin, 12.8 mg/dL; platelet count, 148,000/mm2; white blood cell count, 4800/mm2. Which action is most appropriate for the nurse to implement?
Correct Answer: B
Rationale: The patient's hemoglobin level of 12.8 mg/dL is within the target range for erythropoietin therapy, which is typically 10-12 g/dL. The nurse should continue monitoring the patient and ensure that the hemoglobin does not exceed 12 g/dL, as higher levels can increase the risk of thromboembolic events. Administering additional erythropoietin is unnecessary and potentially harmful. Stopping the medication abruptly is not indicated unless directed by the healthcare provider. Colony-stimulating factors are used to increase white blood cell counts, not hemoglobin levels.
Question 4 of 5
A patient is receiving intravenous (IV) potassium supplements. What is the most important nursing implication when administering this drug?
Correct Answer: B
Rationale: IV potassium must always be diluted in IV fluids and administered via an infusion pump to prevent rapid infusion, which can cause life-threatening cardiac arrhythmias. Administering undiluted potassium or too quickly can lead to hyperkalemia and cardiac arrest. While central lines (A) are sometimes used, potassium can also be given through a peripheral IV if properly diluted. Chilling potassium (C) is unnecessary and could cause discomfort. Preservatives (D) are not a primary concern with IV potassium administration.
Question 5 of 5
While teaching a 76-year-old patient about the adverse effects of his medications, the nurse encourages him to keep a journal of the adverse effects he experiences. This intervention is important for the elderly patient because of which alterations in pharmacokinetics?
Correct Answer: C
Rationale: Elderly patients often experience decreased blood flow to the liver due to age-related changes, which can alter drug metabolism and increase the risk of adverse effects. Keeping a journal of adverse effects helps the patient and healthcare provider monitor and manage these effects effectively. Increased renal excretion, alkaline gastric pH, and reduced adipose tissue are less relevant to the need for monitoring adverse effects. Therefore, the nurse's intervention is most important due to altered liver metabolism in elderly patients.
