ATI Pharmacology Made Easy 4.0 The Hematologic System Questions
Question 1 of 5
Which of the following medications works to lessen the loss of potassium a while at the same time acting as a diuretic
Correct Answer: B
Rationale: Spironolactone is a potassium-sparing diuretic, which means that it helps lessen the loss of potassium from the body while still acting as a diuretic. This medication works by blocking the actions of aldosterone, a hormone that promotes the retention of sodium and water in the body, which can lead to potassium loss. Spironolactone helps to increase potassium levels in the body, making it a suitable choice for patients who are at risk of or experiencing low potassium levels while needing diuretic therapy. Options A, C, and D are not potassium-sparing diuretics, and they do not specifically help in lessening the loss of potassium from the body.
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 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 4 of 5
The home care nurse is caring for a patient newly prescribed a nonselective beta-blocking agent. What would the nurse include in the teaching plan related to this drug? (Select all that apply.)
Correct Answer: A
Rationale: Patients should be taught to change position slowly, avoid driving or operating hazardous machinery, and to pace activities as a result of potential dizziness from orthostatic hypotension in order to avoid injury. Patients should take medicine with meals when possible. Drug is more likely to decrease libido than increase it. Activity levels should be paced and care should be taken not to overdo. The nurse should provide comprehensive patient education to ensure safe and effective use of the medication.
Question 5 of 5
The nurse is monitoring a patient taking furosemide for heart failure. Which electrolyte imbalance must the nurse be alert for?
Correct Answer: C
Rationale: Furosemide, a loop diuretic, promotes the excretion of potassium, sodium, and water. Hypokalemia (low potassium) is a common side effect and can lead to muscle weakness, arrhythmias, and other complications. Hyperkalemia (A) is unlikely with furosemide. Hypernatremia (B) and hyponatremia (D) are less common but should still be monitored.
