ATI Pharmacology Exam Practice Questions
Question 1 of 5
When educating a patient about Regular Insulin, you should include which instruction: ATI PHARMACOLOGY LATEST UPDATE 2022/2023 PROCTORED EXAM -STUDY GUIDE QUESTIONS & ANS 100% CORRECTLY VERIFIED GRADED A+ ATI PHARMACOLOGY LATEST UPDATE 2022/2023 PROCTORED EXAM -STUDY GUIDE QUESTIONS & ANS 100% CORRECTLY VERIFIED GRADED A+
Correct Answer: D
Rationale: It is important to educate a patient that Regular Insulin should be injected subcutaneously to ensure proper absorption of the medication. Injecting the insulin into the subcutaneous tissue allows for a slower and more consistent absorption of the medication, which helps in controlling blood glucose levels effectively. Administering insulin subcutaneously also minimizes the risk of complications associated with other injection sites or techniques.
Question 2 of 5
The client tells the nurse that her symptoms have become worse since she has been using oxymetazoline (Afrin) for nasal congestion. What is the best assessment question for the nurse to ask?
Correct Answer: D
Rationale: Oxymetazoline, a nasal decongestant, can cause rebound congestion (rhinitis medicamentosa) if used beyond 3-5 days, worsening symptoms due to vascular dependence. The best assessment question is how long the client has used it, as prolonged use is the likely culprit, guiding the nurse to educate on discontinuation or seek medical advice. The bottle's age might affect potency but isn't the primary concern for worsening symptoms. Temperature checks for infection, a secondary issue here. Other inhaled medications could interact but don't directly explain rebound effects. The nurse prioritizes duration to pinpoint misuse, a common issue with topical decongestants, making choice D critical for accurate assessment and intervention.
Question 3 of 5
A client calls the clinic and tells the nurse that she has missed taking several of her contraceptive pills during the current cycle. What is the best instruction for the nurse to give the client?
Correct Answer: D
Rationale: Missing several contraceptive pills compromises efficacy, requiring an alternative method for the cycle to prevent pregnancy. Testing assesses outcome, not prevention. Future methods don't address now. Fewer than three still risks failure. D ensures immediate protection, making it the best instruction.
Question 4 of 5
The following are true for adrenaline EXCEPT:
Correct Answer: C
Rationale: Adrenaline, or epinephrine, is a catecholamine that exerts its effects through adrenergic receptors, which are G-protein-coupled, making its action via G-proteins a true statement. Alpha receptor stimulation typically inhibits adenylate cyclase, reducing cyclic AMP (cAMP) production, which aligns with its known pharmacology and is also true. Adrenaline can indeed be administered via inhalation (e.g., for asthma), orally (though less common), and parenterally (e.g., intramuscularly in anaphylaxis), confirming this as true. However, adrenaline does have active metabolites, such as metanephrine and normetanephrine, produced via catechol-O-methyltransferase (COMT) metabolism, making the statement about having no active metabolites false. In cardiac arrest, it facilitates CPR by causing peripheral vasoconstriction, increasing coronary perfusion pressure, which is true. The false statement here is about the absence of active metabolites, as adrenaline's breakdown products retain some activity, a key point in understanding its pharmacokinetics and duration of effect.
Question 5 of 5
Which one of the following antipsychotics has been shown to be a partial agonist at the dopamine D2 receptor?
Correct Answer: A
Rationale: Aripiprazole, a third-generation antipsychotic, acts as a partial agonist at D2 receptors, stabilizing dopamine activity: it activates receptors in low-dopamine states (e.g., negative symptoms) and competes with excess dopamine (e.g., psychosis), reducing side effects like EPS. Clozapine, a second-generation drug, has weak D2 affinity, targeting 5HT2 and other receptors. Haloperidol, a first-generation antipsychotic, is a D2 antagonist. Risperidone and thioridazine block D2 fully, not partially. Aripiprazole's unique partial agonism, confirmed by pharmacological data, balances efficacy and tolerability, distinguishing it in schizophrenia treatment.
