Question 1 of 5
What is the peak range of regular insulin?
Correct Answer: D
Rationale: The peak range of regular insulin typically occurs between 1 to 5 hours after administration. This means that regular insulin will reach its maximum effectiveness in lowering blood sugar levels during this time frame. Patients should be aware of this peak range to help manage their diabetes effectively and time their meals and activities accordingly.
Question 2 of 5
Which statement about ARBs does the nurse identify as being true?
Correct Answer: A
Rationale: One of the key differences between Angiotensin II Receptor Blockers (ARBs) and Angiotensin-Converting Enzyme (ACE) inhibitors is their impact on potassium levels. While both medications can cause hyperkalemia (high potassium levels), it is generally considered more likely to occur with ARBs compared to ACE inhibitors. This is because ACE inhibitors inhibit the breakdown of bradykinin, which in turn can enhance potassium retention, increasing the risk of hyperkalemia. Therefore, the nurse would correctly identify this statement about ARBs as being true.
Question 3 of 5
During diuretic therapy, the nurse monitors the fluid and electrolyte status of the patient. Which assessment findings are symptoms of hyponatremia? (Select all that apply.)
Correct Answer: B
Rationale: Lethargy is a common symptom of hyponatremia, which is a low sodium level in the blood. it is often associated with a decrease in brain function due to the imbalance of electrolytes.
Question 4 of 5
A liquid preparation of K penicillin V contains 125mg/5ml. If you want a patient to take 250mg. each dose, you would prescribe ___ per
Correct Answer: C
Rationale: To prescribe 250mg of K penicillin V, you would need to have 10ml of the liquid preparation (125mg/5ml x 10ml = 250mg). Since 1 teaspoon (tsp) is approximately equal to 5ml, you would need to prescribe 2 teaspoons of the liquid preparation for the patient to take 250mg per dose.
Question 5 of 5
A 56-year-old alcoholic man consumes a six-pack of beer before going to bed. After being absorbed from his gut, blood carries the alcohol through the portal vein into the liver where it can be metabolized. Ethanol is metabolized in multiple steps by various enzymes, including alcohol dehydrogenase. Which of the following describes a characteristic of this enzyme?
Correct Answer: D
Rationale: Alcohol dehydrogenase (ADH) metabolizes ethanol to acetaldehyde and is inhibited by fomepizole , used in poisonings. It doesn't act on acetaldehyde or acetate . Disulfiram blocks aldehyde dehydrogenase. ADH's role initiates ethanol breakdown.
