1. A nurse is preparing to administer methylprednisolone 10 mg by IV bolus. The amount available is methylprednisolone injection 40-mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Do not use a trailing zero.)
- A. 0.3 mL
- B. 0.25 mL
- C. 0.4 mL
- D. 0.5 mL
Correct answer: A
Rationale: To calculate the mL to administer, use the formula: Dose required (mg) ÷ Stock concentration (mg/mL) = Volume to administer (mL). In this case, 10 mg ÷ 40 mg/mL = 0.25 mL. However, when rounding to the nearest tenth, the answer should be 0.3 mL. Therefore, the nurse should administer 0.3 mL. Choice A is the correct answer. Choice B (0.25 mL) is the result obtained before rounding. Choice C (0.4 mL) and Choice D (0.5 mL) are incorrect calculations.
2. A group of newly licensed nurses is being taught about the Braden Scale by a nurse. Which of the following responses by a newly licensed nurse indicates an understanding of the teaching?
- A. “The client’s age is not a factor in the measurement.”
- B. “The scale measures six elements.”
- C. “A lower score indicates a higher risk of pressure ulcers.”
- D. “Each element is scored on a range from 1 to 4 points.”
Correct answer: B
Rationale: Choice B is the correct answer because the Braden Scale measures six elements: Sensory Perception, Moisture, Activity, Mobility, Nutrition, Friction, and Shear. The other choices are incorrect because: Choice A states that the client's age is not a factor in the measurement, which is accurate as age is not included in the Braden Scale. Choice C incorrectly states that a lower score indicates a higher risk of pressure ulcers, which is the opposite of how the Braden Scale works. Choice D inaccurately describes the scoring range of each element on the Braden Scale, which is not from 1 to 4 points but rather from 1 to 3.
3. What is the most important aspect for the nurse to include in the discharge plan for a client performing his own dressing changes at home following abdominal surgery?
- A. Demonstration of appropriate hand hygiene
- B. Explanation of wound care technique
- C. Review of signs and symptoms of infection
- D. Instructions for when to contact the healthcare provider
Correct answer: A
Rationale: The most critical aspect for the nurse to include in the discharge plan for a client performing his own dressing changes at home following abdominal surgery is the demonstration of appropriate hand hygiene. Proper hand hygiene is essential to prevent the introduction of infection during dressing changes. While wound care technique, signs and symptoms of infection, and instructions for contacting the healthcare provider are all important components of the discharge plan, ensuring the client understands and practices proper hand hygiene is paramount to minimize the risk of infection. This choice takes precedence as it directly addresses infection prevention during the dressing changes, which is crucial for successful post-operative recovery.
4. When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?
- A. Bleeding time
- B. Coagulation time
- C. Prothrombin time
- D. Partial thromboplastin time
Correct answer: C
Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.
5. The clinician is assessing a client with a Stage 2 skin ulcer. Which of the following treatments is most effective to promote healing?
- A. Covering the wound with a dry dressing
- B. Using hydrogen peroxide soaks
- C. Leaving the area open to dry
- D. Applying a hydrocolloid or foam dressing
Correct answer: D
Rationale: Applying a hydrocolloid or foam dressing is the most effective treatment to promote healing for a Stage 2 skin ulcer. These dressings create a moist environment that supports healing and prevents further tissue damage. Option A (covering the wound with a dry dressing) can lead to drying out the wound bed, hindering healing. Option B (using hydrogen peroxide soaks) can be too harsh and may damage the surrounding healthy tissue. Option C (leaving the area open to dry) can delay healing as it does not provide the necessary moist environment for optimal wound healing.
