ATI Pharmacology Made Easy 4.0 Infection Questions
Question 1 of 5
The client takes calcium supplements. What is the best instruction by the nurse?
Correct Answer: B
Rationale: Calcium absorbs best with food-e.g., fat aids uptake, per pharmacokinetics-unlike empty stomach. Insomnia isn't typical-constipation is. Vitamin D matters-enhances absorption. Meal timing optimizes use, per guidance.
Question 2 of 5
Lithium is used to?
Correct Answer: C
Rationale: Lithium is commonly used as a mood stabilizer in the treatment of bipolar disorder. It helps reduce the intensity of manic episodes, thereby stabilizing the patient's mood and preventing extreme mood swings. While lithium is primarily known for its mood-stabilizing effects, it is not used to lower blood glucose, slow the heart, or heal ulcers.
Question 3 of 5
The nurse is doing health teaching with a patient with psoriasis. Which nursing implication is a priority for a patient on infliximab to treat psoriasis?
Correct Answer: D
Rationale: Infliximab, a biologic agent used to treat psoriasis, can suppress the immune system and increase the risk of infections and blood disorders. Monitoring the complete blood count (
D) is a priority to detect neutropenia, anemia, or thrombocytopenia. Monitoring weight (
A), electrolytes (
B), or urine output (
C) is not typically associated with infliximab therapy.
Question 4 of 5
The nurse teaches the client about the difference between oral and nasal decongestants. The nurse evaluates that learning has been effective when the client makes which statement?
Correct Answer: A
Rationale: Oral decongestants risk hypertension , unlike nasal ones, showing effective learning. Nasal use beyond days causes rebound. Only nasal causes rebound . Efficacy varies. A reflects key differences, making it the best statement.
Question 5 of 5
All are true about penicillins EXCEPT:
Correct Answer: B
Rationale: Penicillins cross the blood-brain barrier mainly when meninges are inflamed (e.g., meningitis), a true statement due to increased permeability. They do require dose adjustment in renal failure, as they're renally excreted, making the lack of adjustment false and the exception. They inhibit bacterial cell wall synthesis by blocking peptidoglycan cross-linkage, a true mechanism. Piperacillin is effective against Pseudomonas, especially with tazobactam, which is true. Only 5-10% of those with prior penicillin allergy react again, also true. The renal adjustment need is critical, as accumulation risks toxicity like seizures, guiding safe prescribing in kidney dysfunction.
