ATI Pharmacology Made Easy 4.0 The Hematologic System Questions
Question 1 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.
Question 2 of 5
Which of the following are common side effects when taking the drug Phenytoin. Select all that apply.
Correct Answer: A
Rationale: Phenytoin is an antiepileptic drug that can commonly cause drowsiness, ataxia (loss of full control of bodily movements), and dry mouth as side effects. These side effects are important to monitor in patients taking Phenytoin to ensure their safety and well-being. Increased suicidal thoughts are not a common side effect associated with Phenytoin.
Question 3 of 5
The patient receives aspirin. The nurse assesses an adverse effect to this drug when the patient makes which response?
Correct Answer: A
Rationale: Aspirin, an NSAID, inhibits platelet aggregation and can cause gastrointestinal bleeding, leading to dark, tarry stools (melena) from upper GI hemorrhage . This adverse effect requires urgent assessment, as it signals potential internal bleeding, a serious complication. Nasal stuffiness isn't linked to aspirin unless related to an allergic reaction (rare). Headaches from lights suggest photophobia, unrelated to aspirin's effects. Frequent urination isn't a typical side effect. The nurse identifies dark stools as a critical sign of aspirin's impact on gastric mucosa and coagulation, necessitating intervention, making choice A the correct adverse effect to assess.
Question 4 of 5
A patient has been taking a beta blocker for 4 weeks as part of his antianginal therapy. He also has type II diabetes and hyperthyroidism. When discussing possible adverse effects, the nurse will include which information?
Correct Answer: A
Rationale: Option E is the correct answer. When a patient with type II diabetes is taking a beta blocker, it's important to monitor blood glucose levels regularly for possible changes in glucose levels. Beta blockers can mask the symptoms of hypoglycemia, such as tremors and rapid heartbeat, which can make it harder for patients to recognize when their blood sugar is too low. On the other hand, beta blockers can also potentially lead to hyperglycemia as they can blunt the body's response to hypoglycemia by inhibiting the release of counter-regulatory hormones like epinephrine. Therefore, monitoring blood glucose levels is crucial in such patients to prevent complications related to blood sugar fluctuations.
Question 5 of 5
What decreases the renin angiotensin aldosterone system?
Correct Answer: C
Rationale: ACE inhibitors decrease the renin angiotensin aldosterone system by blocking the angiotensin-converting enzyme (ACE), which converts angiotensin I to angiotensin II. By inhibiting this enzyme, ACE inhibitors reduce the production of angiotensin II, a potent vasoconstrictor, and lower aldosterone secretion. This leads to vasodilation, decreased blood pressure, and reduced retention of sodium and water. Consequently, ACE inhibitors are commonly used in the management of hypertension, heart failure, and chronic kidney disease.
