ATI Pharmacology Made Easy 4.0 The Hematologic System Questions
Question 1 of 5
Which of the following is described as the route of drug administration where the drug is placed directly into the GIT from where absorption occurs.
Correct Answer: A
Rationale: Enteral drug administration is the route where the drug is placed directly into the gastrointestinal tract (GIT), such as through the mouth (oral administration) or through a feeding tube. Once administered, the drug is absorbed through the walls of the GI tract into the bloodstream for systemic distribution. This is in contrast to parenteral routes where drugs are administered by methods other than through the digestive system, such as injections, inhalation, or topical application. Intravenous (IV) administration, specifically mentioned in the question, is a type of parenteral route where drugs are injected directly into a vein for rapid and complete systemic distribution.
Question 2 of 5
Which statement about ARBs does the nurse identify as being true?
Correct Answer: A
Rationale: Angiotensin II Receptor Blockers (ARBs) are less likely to cause cough compared to ACE inhibitors. However, one of the notable adverse effects associated with ARBs is hyperkalemia. ARBs can lead to an increase in potassium levels in the blood more so than ACE inhibitors. Therefore, the nurse should recognize that hyperkalemia is more likely to occur with ARBs than when using ACE inhibitors.
Question 3 of 5
The physician has prescribed haloperidol (Haldol) for the patient with schizophrenia. What is the priority patient outcome?
Correct Answer: B
Rationale: Haloperidol treats schizophrenia's positive symptoms, but compliance is the priority outcome, as relapse follows non-adherence. Fluids/fiber manage side effects. Hallucination reduction depends on compliance. Restlessness signals issues, not a goal. B ensures treatment success, making it the priority.
Question 4 of 5
Basic component of a blood clot
Correct Answer: A
Rationale: Platelets are the basic component of a blood clot. When there is an injury to a blood vessel, platelets are activated and aggregate at the site to form a plug, which is the first step in the clotting process. Platelets release chemicals that further promote clot formation, eventually leading to the formation of a stable blood clot. While fibrin, thrombin, thromboxane, and ADP are also involved in the clotting process, platelets play a central role in the initial formation of a blood clot.
Question 5 of 5
The nurse is caring for a client receiving IV vancomycin (Vancocin). Which infusion-related reaction should the nurse monitor for?
Correct Answer: A
Rationale: Vancomycin, used for resistant infections, can cause red man syndrome 'flushing, rash, and pruritus on the upper body'due to histamine release from rapid IV infusion. Monitoring for this allows slowing the rate (e.g., over 1-2 hours), preventing discomfort or anaphylactoid reactions. Hypotension may occur secondary to this but isn't primary. Fever and nausea are less specific to infusion speed. Red man syndrome's distinct presentation ties directly to vancomycin's administration, a well-known risk mitigated by nursing vigilance. This focus ensures safe delivery, distinguishing it from systemic effects, making A the key reaction to watch during infusion.
