Extract:
Question 1 of 5
A client admitted to the hospital has been placed on furosemide (Lasix) for the treatment of heart failure. Which side effect should the nurse monitor for associated with furosemide (Lasix)?
Correct Answer: A
Rationale: Hypokalemia, or low potassium levels, is a common side effect associated with furosemide. Furosemide is a loop diuretic that works by inhibiting the reabsorption of sodium and chloride in the kidneys, which leads to an increase in urine output. This process can also cause the body to lose potassium, making hypokalemia a significant risk.
Question 2 of 5
A client is receiving Total Parenteral Nutrition (TPN) while admitted in the inpatient setting. Which of the following conditions can occur if the nurse abruptly stops TPN?
Correct Answer: C
Rationale: Abrupt cessation of TPN stops the glucose supply suddenly, risking hypoglycemia. TPN is high in dextrose, so stopping it without tapering can cause dangerous blood sugar drops.
Question 3 of 5
A client who suffers from hypertension is prescribed propranolol. The nurse would educate the client on which side effects associated with this medication? (Select all that apply)
Correct Answer: B
Rationale: Propranolol can mask hypoglycemia symptoms cause bronchoconstriction especially in asthma patients
Question 4 of 5
A client frequently takes diphenhydramine (Benadryl) to alleviate his upper respiratory symptoms associated with allergies. Which of the following mechanisms of action applies to diphenhydramine (Benadryl)?
Correct Answer: D
Rationale: Blocking histamine receptors and inhibiting acetylcholine by binding to H1 receptors is the correct mechanism of action for diphenhydramine. This antihistamine drug effectively reduces allergic symptoms by preventing histamine from binding to H1 receptors. Additionally, diphenhydramine has anticholinergic effects, which means it can also inhibit the neurotransmitter acetylcholine, contributing to its sedative and anti-nausea properties. This dual action makes diphenhydramine effective in treating various allergic reactions and related symptoms.
Question 5 of 5
A nurse is preparing an in-service program about preventing medication errors when transcribing a prescription. The nurse is using a dosage example of two tenths of a milligram. Which of the following examples should the nurse use to show appropriate transcription of this dosage?
Correct Answer: D
Rationale: Writing the dosage as 0.2 mg is the correct way to transcribe two tenths of a milligram. It uses a leading zero before the decimal point, which helps prevent dosage errors.
