A client receives a prescription for 500 mL of lactated Ringer's IV to be infused over 4 hours. The IV administration set delivers 20 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["42"]
Flow rate (gtt/min) = (Total volume× Drop factor)/Total time
= (500×20)/240
= 1000/240
= 41.67, round off to the nearest whole number
= 42
Thus, the nurse should regulate the infusion at 42 gtt/min.

Correct Answer is B,D,C,A
Explanation
- Inspect head for trauma. Head injuries can be life-threatening, so the nurse must first assess for signs of skull fractures, concussions, or intracranial bleeding that could explain the headache.
- Perform a neurological exam. If head trauma is suspected, a neurological exam is essential to assess for altered mental status, coordination deficits, or signs of increased intracranial pressure.
- Evaluate range of motion of all joints. After ruling out life-threatening conditions, the nurse should assess for musculoskeletal injuries, fractures, or soft tissue damage from physical abuse.
- Provide a safety plan to prevent further violence. Once the client is medically stable, the nurse should provide resources, assess risk for further harm, and develop a safety plan to prevent future abuse.
Correct Answer is D
Explanation
A. Hyperpigmented areas that vary in form and color and are slightly elevated from the skin
These findings are characteristic of skin conditions such as lentigines or melanocytic nevi rather than acne vulgaris. Acne typically presents with inflammatory and non-inflammatory lesions, not hyperpigmented patches of varying color and elevation.
B. Small, skin-colored, pedunculated papules in areas of skin folds and on other areas as skin tags
Skin tags, also known as acrochordons, are benign growths that develop in areas of skin friction. They are not associated with acne vulgaris, which primarily affects the sebaceous glands and hair follicles.
C. Sharply demarcated silvery scaling plaques with underlying redness on the elbows and knees
These findings are typical of psoriasis, a chronic autoimmune skin condition. Acne vulgaris does not present with silvery scaling plaques or well-defined erythematous lesions in these locations.
D. Hyperactive sebaceous areas forming comedones, papules, pustules on the face, neck, and upper back
Acne vulgaris results from increased sebum production, follicular hyperkeratinization, bacterial overgrowth, and inflammation. It commonly presents with comedones (blackheads and whiteheads), inflammatory papules, pustules, and sometimes nodules, predominantly affecting the face, neck, chest, and upper back.
