Question 1 of 5
A nurse is preparing to administer Igrasm 5mcg/kg/day subcutaneous to a client who weighs 143 lb. How many mcg should the nurse administer per day?
Correct Answer: 325 mcg
Rationale: The correct answer is 325 mcg. First, convert the client's weight from lb to kg: 143 lb รท 2.2 = 65 kg. Next, calculate the daily dose: 5 mcg/kg/day x 65 kg = 325 mcg/day.
Therefore, the nurse should administer 325 mcg per day.
Other choices are incorrect because they do not follow the correct conversion of weight to kg and do not calculate the dose accurately based on the weight and prescribed dosage.
Question 2 of 5
A nurse is preparing to initiate IV therapy for a client. Which of the following sites should the nurse use to place the peripheral IV catheter?
Correct Answer: A
Rationale: The correct answer is A: Nondominant dorsal venous arch. This site is preferred for peripheral IV catheter placement due to the larger vein diameter, ease of access, and reduced risk of complications like nerve damage or infiltration. The nondominant side is chosen to prevent disruption of daily activities. The dorsal venous arch is a superficial vein that is easily visible and palpable, making it suitable for successful cannulation. It also allows for optimal flow rate and minimizes the risk of phlebitis.
Choices B, C, and D are not ideal for various reasons such as smaller vein size, increased risk of nerve damage, and difficulty in accessing or securing the catheter.
Question 3 of 5
A nurse is assessing a client who is taking an osmotic laxative. Which of the following findings should the nurse identify as an indication of fluid volume deficit?
Correct Answer: D
Rationale: The correct answer is D: Oliguria. Osmotic laxatives, such as lactulose or polyethylene glycol, work by drawing water into the colon to soften the stool. If a client on osmotic laxatives is experiencing oliguria (decreased urine output), it can be a sign of fluid volume deficit due to the body trying to conserve water. Nausea (
A) is a common side effect of osmotic laxatives but not a specific indicator of fluid volume deficit. Weight gain (
B) is not associated with fluid volume deficit. Headache (
C) can be caused by various factors and is not a specific sign of fluid volume deficit.
Question 4 of 5
A nurse is reviewing the laboratory results of a client who is taking amitriptyline. Which of the following laboratory values should the nurse report to the provider?
Correct Answer: A
Rationale: The correct answer is A.
Total bilirubin levels should be reported because amitriptyline can cause hepatotoxicity. Elevated bilirubin could indicate liver damage. Option B, potassium level, is not typically affected by amitriptyline. Option C, hematocrit, and option D, WBC count, are not directly related to amitriptyline use. Options E, F, and G are not provided. In summary, the nurse should report elevated total bilirubin levels due to potential hepatotoxicity from amitriptyline.
Question 5 of 5
A nurse is caring for a client who is taking lithium and reports starting a new exercise program. The nurse should assess the client for which of the following electrolyte imbalances?
Correct Answer: C
Rationale: The correct answer is C: Hyponatremia. When a client taking lithium starts a new exercise program, they may sweat more, leading to sodium loss. Hyponatremia is characterized by low sodium levels in the blood, which can be exacerbated by the diuretic effect of lithium. This can result in symptoms such as confusion, muscle cramps, weakness, and seizures. Assessing for hyponatremia is crucial to prevent complications.
Incorrect choices:
A: Hypocalcemia - Not directly related to lithium or exercise.
B: Hypokalemia - More commonly associated with diuretic use or excessive potassium loss.
D: Hypomagnesemia - More commonly seen in alcoholism or malnutrition.
