ATI Pharmacology Practice A 2023 Questions
Question 1 of 5
What patient history would the nurse recognize as a contraindication for beginning Niacin therapy?
Correct Answer: B
Rationale: Gout is a metabolic disorder characterized by elevated levels of uric acid in the blood, which can be exacerbated by niacin therapy. Niacin can increase uric acid levels, potentially leading to gout flare-ups in patients with a history of gout. Therefore, a history of gout would be recognized as a contraindication for beginning Niacin therapy.
Question 2 of 5
A client is prescribed clonidine (Catapres) for hypertension. Which statement by the client indicates effective teaching?
Correct Answer: C
Rationale: Clonidine, an alpha-2 agonist, lowers BP but risks rebound hypertension if stopped abruptly. Tapering off shows understanding, preventing this danger. Stopping if normal or extra doses risk instability. Chewing isn't advised'oral absorption suffices. Tapering aligns with clonidine's withdrawal risk, critical in hypertension management, making C the statement of effective teaching.
Question 3 of 5
A neighbor tells nurse Maureen he has to have surgery and is reluctant to have any blood product transfusions because of a fear of contracting an infection. He asks the nurse what are his options. The nurse teaches the person that the safest blood product is:
Correct Answer: C
Rationale: An autologous blood product is the safest option for the neighbor who is reluctant to have blood transfusions due to a fear of contracting an infection. Autologous blood is blood that is donated by the patient themselves prior to surgery. This type of blood product eliminates the risk of transmitting infections from other donors, as the blood comes from the patient's own body. It is considered the safest option for those concerned about infection transmission during blood transfusions.
Question 4 of 5
The nurse is caring for a patient who is receiving warfarin (Coumadin) and notes bruising and petechiae on the patient™s extremities. The nurse will request an order for which laboratory test?
Correct Answer: B
Rationale: The nurse should request an order for a platelet level to assess the patient's platelet count. Warfarin (Coumadin) is an anticoagulant medication that works by interfering with the blood clotting process. Bruising and petechiae may be signs of decreased platelet count or impaired platelet function. Monitoring the platelet level will help determine if the patient's symptoms are related to thrombocytopenia (low platelet count). While the International Normalized Ratio (INR) is commonly used to monitor the effects of warfarin therapy, in this case, the presence of bruising and petechiae suggest a need to assess platelet levels specifically. PT and aPTT tests assess the clotting function of factors produced by the liver and are not directly related to platelet count. Vitamin K level may be tested in cases of suspected vitamin K deficiency, but it would not directly help in assessing
Question 5 of 5
All are specialized transports. except:
Correct Answer: D
Rationale: Simple diffusion is a passive transport process that does not require specialized transport proteins or energy expenditure. It involves the movement of molecules from an area of higher concentration to an area of lower concentration without the aid of a protein channel or carrier. In contrast, active transport, facilitated diffusion, and pinocytosis are specialized transports that utilize specific proteins and mechanisms to help move molecules across cell membranes. Active transport requires energy to move molecules against their concentration gradient, facilitated diffusion involves the use of specific protein channels or carriers to facilitate movement, and pinocytosis is a form of endocytosis where cells engulf fluid droplets.
