Question 1 of 5
Which statement regarding medication distribution within the body is accurate?
Correct Answer: C
Rationale: Lipid-soluble drugs distribute widely, crossing membranes like the blood-brain barrier easily, unlike water-soluble ones. The barrier blocks some, not all, drugs. High blood flow aids delivery, not hinders. Protein complexes limit free drug, not enable crossing. Lipid solubility enhances distribution, a pharmacokinetic truth.
Question 2 of 5
A 36-year-old woman grocery store manager with a fair complexion and blue eyes presents to her primary care physician for a routine exam. She mentions a friend of hers who is taking bimatoprost to increase the length and amount of her eyelashes and asks if you would recommend it for her. Her past medical history is significant for migraine headaches. Which of the following is a side effect you should warn her about?
Correct Answer: B
Rationale: Bimatoprost for eyelashes risks permanent iris darkening , increasing melanin, especially in light eyes. Glaucoma is its therapeutic use, not a side effect here. Stevens-Johnson , weight gain , and migraines (E) aren't linked. Darkening is a key cosmetic concern.
Question 3 of 5
The nurse administers calcium intravenously (IV) to the client. What will a key assessment by the nurse include?
Correct Answer: B
Rationale: IV calcium risks infiltration-site assessment (e.g., swelling) ensures safety, per protocol. Glucose/potassium aren't directly tied-edema is secondary. Site check prevents complications, per administration.
Question 4 of 5
A patient is receiving 10 mEq of potassium chloride in 100 mL of normal saline intravenously (IV) to infuse over 1 hour via infusion pump. The patient has a 22-gauge peripheral IV in his right forearm and reports pain at the insertion site; the nurse notes that the site is reddened, warm, and tender to the touch. Which action would the nurse take?
Correct Answer: C
Rationale: The patient's symptoms of pain, redness, warmth, and tenderness at the IV site indicate possible infiltration or phlebitis, which can lead to tissue damage or infection. The nurse should stop the infusion and discontinue the IV immediately to prevent further complications. Aspirating and slowing the rate (
A) is inappropriate in this situation. Inserting a central line (
B) is not the immediate priority. Applying warm compresses (
D) may be done after discontinuing the IV, but it is not the first action.
Question 5 of 5
Two days after admission, the nurse is reviewing laboratory results of the patient. Which is the most common electrolyte finding resulting from the administration of furosemide (Lasix)?
Correct Answer: C
Rationale: The most common electrolyte finding resulting from the administration of furosemide (Lasix) is hypokalemia. Furosemide is a loop diuretic that works by blocking the reabsorption of sodium and chloride in the ascending loop of Henle in the kidneys. This results in increased excretion of water and electrolytes, including potassium. Hypokalemia can lead to various complications such as cardiac arrhythmias, muscle weakness, and fatigue.
Therefore, patients receiving furosemide should be closely monitored for potassium levels, and supplementation may be necessary to prevent and treat hypokalemia.
