Extract:
Question 1 of 5
A nurse is caring for a client who has acute respiratory distress syndrome (ARDS) and requires mechanical ventilation. The client receives a prescription for pancuronium. The nurse recognizes that this medication is for which of the following purposes?
Correct Answer: B
Rationale: The correct answer is B: Suppress respiratory effort. Pancuronium is a neuromuscular blocking agent that paralyzes skeletal muscles, including the muscles involved in breathing. In ARDS, the client may have difficulty breathing due to lung damage, so pancuronium can be used to facilitate mechanical ventilation by preventing respiratory muscle movement. This allows the ventilator to control the client's breathing without interference. The other choices are incorrect because pancuronium does not induce sedation (
A), affect chest wall compliance (
C), or decrease respiratory secretions (
D). It solely works to suppress respiratory effort by blocking neuromuscular transmission.
Question 2 of 5
Correct Answer:
Rationale: Question: Which of the following is NOT a primary color in the subtractive color model?
Choices: A: Red, B: Blue, C: Yellow, D: Green, E: Cyan, F: Magenta, G: Black
Correct Answer: D: Green
Rationale: In the subtractive color model (used in printing), primary colors are Cyan, Magenta, and Yellow. When combined, they create a range of colors. Green is a secondary color in this model, created by mixing Cyan and Yellow.
Therefore, Green is NOT a primary color.
Summary:
Choices A, B, C, E, F are incorrect as they are primary colors in the subtractive color model.
Choice G, Black, is also incorrect as it is the key color used for shading and darkness, not a primary color in this model.
Question 3 of 5
A nurse is preparing a client who is postoperative following a below-the-knee amputation for a leg prosthesis fitting. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Wrap the stump with an elastic bandage in a figure-eight configuration. This action helps reduce swelling, provide support, and shape the stump for prosthesis fitting. Wrapping in a figure-eight pattern ensures even compression and prevents constriction.
Choice B is incorrect as frequent re-wrapping can disrupt wound healing.
Choice C is unnecessary and may cause discomfort.
Choice D is incorrect as securing the bandage at the lowest joint can lead to constriction and hinder circulation.
Question 4 of 5
A nurse is preparing to administer fluconazole 400 mg by intermittent IV bolus daily. Available is fluconazole 400 mg in 0.9% sodium chloride (NaCl) 200 mL to infuse over 2 hours. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 100
Rationale:
Correct Answer: 100
Rationale:
To calculate the IV pump rate, use the formula: (Volume to be infused in mL) / (Time in hours). In this case, 200 mL over 2 hours. 200 / 2 = 100 mL/hr.
Summary:
A. Incorrect. Not the correct calculation for the IV pump rate.
B. Incorrect. Not the correct calculation for the IV pump rate.
C. Incorrect. Not the correct calculation for the IV pump rate.
D. Incorrect. Not the correct calculation for the IV pump rate.
E. Incorrect. Not the correct calculation for the IV pump rate.
F. Incorrect. Not the correct calculation for the IV pump rate.
G. Incorrect. Not the correct calculation for the IV pump rate.
Question 5 of 5
A nurse is reviewing the laboratory results of a client who has a pressure ulcer. The nurse should identify an elevation in which of the following laboratory values as an indication that the client has developed an infection?
Correct Answer: A
Rationale: The correct answer is A: WBC count. An elevation in WBC count indicates the presence of infection as the body releases more white blood cells to fight off pathogens. In the case of a pressure ulcer, an increased WBC count suggests bacterial invasion and inflammation at the site of the ulcer. BUN (choice
B) and Potassium (choice
C) are not specific indicators of infection and are more related to kidney function and electrolyte balance, respectively.
Therefore, they are not appropriate for determining infection in this context.
