Fundamentals of Nursing Medication Administration Practice Questions Questions
Question 1 of 5
How much dantrolene is needed to treat malignant hyperthermia in a patient weighing 70 kg?
Correct Answer: B
Rationale: The standard initial dose of dantrolene for malignant hyperthermia is 2.5 mg/kg IV, repeated as needed up to a maximum of 10 mg/kg. For a 70 kg patient, 2.5 mg/kg × 70 kg = 175 mg initially. However, the total dose may reach 10 mg/kg × 70 kg = 700 mg. Given the options, 600 mg is closest to a practical total dose in a crisis, though typically it’s administered in increments. (Note: Multiple '600 mg' listings appear to be an OCR error; only one is valid.)
Question 2 of 5
A client with a surgical wound on the abdomen has a negative pressure wound therapy (NPWT) device attached to the wound. Which action should the nurse take when caring for this client?
Correct Answer: C
Rationale: Negative pressure wound therapy (NPWT) is a device that applies subatmospheric pressure to the wound bed, which promotes granulation tissue formation, removes excess fluid and debris, and reduces edema and bacterial colonization. The nurse should ensure that the dressing is sealed and airtight around the wound to maintain negative pressure and prevent air leaks.
Question 3 of 5
A client with diabetes mellitus has a diabetic foot ulcer on the left heel. The nurse is preparing to apply a hydrocolloid dressing to the wound. What is an advantage of using this type of dressing?
Correct Answer: D
Rationale: Hydrocolloid dressings are occlusive or semi-occlusive dressings that adhere to the skin and form a gel-like substance over the wound. This creates a moist environment that stimulates autolytic debridement, which is the natural breakdown of necrotic tissue by enzymes in the wound fluid.
Question 4 of 5
A nurse is preparing to change a dressing on a client's surgical incision. Which type of dressing should the nurse use to promote autolytic debridement of the wound?
Correct Answer: D
Rationale: The nurse should use a hydrogel dressing to promote autolytic debridement of the wound. Autolytic debridement is a natural process that uses the body's own enzymes and moisture to liquefy and remove necrotic tissue from a wound. Hydrogel dressings provide hydration and moisture to dry wounds and facilitate autolytic debridement.
Question 5 of 5
A nurse is assessing a client with a pressure ulcer on the sacrum. Which finding should the nurse report to the provider immediately?
Correct Answer: A
Rationale: The wound with a foul odor and purulent drainage indicates an infection, which can delay healing and cause systemic complications, such as sepsis. The nurse should report this finding to the provider immediately and obtain a wound culture and sensitivity test.
