Question 1 of 5
A nurse is planning teaching for a client who is trying to quit smoking. Which of the following instructions about nicotine replacement options should the nurse include?
Correct Answer: B
Rationale: The correct answer is B: Do not drink beverages while sucking on a nicotine lozenge. This instruction is important because beverages can interfere with the absorption of nicotine from the lozenge. Nicotine replacement therapy works best when the nicotine is absorbed properly, so avoiding beverages while using the lozenge will help ensure its effectiveness. Changing the nicotine patch every other day (choice
A) is incorrect as patches are typically changed daily. Chewing nicotine gum for 10 minutes before spitting it out (choice
C) is incorrect as the gum should be chewed until a tingling sensation is felt, then parked between the cheek and gum. Administering 2 sprays of nicotine nasal spray in each nostril with each dose (choice
D) is incorrect as the dosage is usually one spray in each nostril.
Question 2 of 5
A nurse is caring for a client who has a prescription for total parenteral nutrition (TPN). Which of the following routes of administration should the nurse use?
Correct Answer: C
Rationale: The correct answer is C: Central venous access device. TPN is a highly concentrated solution that provides all the nutrients a person needs intravenously. A central venous access device allows for the infusion of TPN into a large central vein, such as the superior vena cava, ensuring immediate access to the bloodstream for rapid absorption. Using other routes like subcutaneous (
A), intravenous (
B), or midline catheter (
D) may not be suitable due to the high osmolarity of TPN, which can cause irritation and damage to smaller veins.
Therefore, a central venous access device is the most appropriate and safe route for administering TPN.
Question 3 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 ÷ 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 4 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 5 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.
