ATI Pharmacology Made Easy 4.0 The Hematologic System Questions
Question 1 of 5
A 17-year-old client is taking phenytoin (Dilantin) for the treatment of seizures. Phenytoin blood level reveals to be 25 mcg/ml. Which of the following symptoms would be expected as a result of the laboratory result?
Correct Answer: D
Rationale: A phenytoin level of 25 mcg/ml is above the therapeutic range (10-20 mcg/ml) and can cause toxicity symptoms such as nystagmus, ataxia, and confusion. Hyperactivity and tremors are not typical signs of phenytoin toxicity. Therefore, nystagmus is the expected symptom.
Question 2 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 3 of 5
A client taking probenecid is complaining of gout pain. Which of the following medication should the nurse expect to be administered?
Correct Answer: A
Rationale: Acetaminophen is often used to manage pain in patients with gout, as it does not interfere with uric acid levels. Aspirin is contraindicated because it can reduce the effectiveness of probenecid. Orphenadrine and tizanidine are muscle relaxants and are not indicated for gout pain. Acetaminophen is a safe and effective option for pain relief in this context.
Question 4 of 5
A patient is taking levofloxacin. What does the nurse know to be true regarding this drug?
Correct Answer: D
Rationale: Levofloxacin is a fluoroquinolone antibiotic available in both oral and intravenous forms. It is not classified as an aminoglycoside. A well-documented adverse effect of fluoroquinolones is tendon rupture, particularly in older adults and those on corticosteroid therapy. Hypertension is not a common side effect of levofloxacin. Patients should be advised to report any tendon pain or swelling immediately.
Question 5 of 5
The nurse is providing education about the use of sublingual nitroglycerin tablets. She asks the patient, What would you do if you experienced chest pain while mowing your yard? You have your bottle of sublingual nitroglycerin with you. Which actions by the patient are appropriate in this situation? (Select all that apply.)
Correct Answer: A
Rationale: A. Stop the activity, and lie down or sit down: This is an appropriate action to take when experiencing chest pain to reduce the workload on the heart and decrease oxygen demand.
