A client who had a knee replacement surgery and received a prescription for enoxaparin 30 mg subcutaneously every 12 hours for 10 days. The medication is available in 30 mg per 0.3 mL pre-filled syringes. How many mL should the practical nurse (PN) administer each day? (Enter numerical value only.)

A. Blood pressure: A normal blood pressure for an adolescent is 110/70 mm Hg. The question does not provide the adolescent's blood pressure, so it cannot be determined if it requires follow-up or not.
B. Capillary refill: A normal capillary refill time is less than 2 seconds. A prolonged capillary refill time indicates impaired blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
C. Pedal pulse: A normal pedal pulse is +2 or +3. A weak pedal pulse (+1) indicates reduced blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.

D. Heart rate: A normal heart rate for an adolescent is 60 to 100 beats per minute. The question does not provide the adolescent's heart rate, so it cannot be determined if it requires follow-up or not.
E. Skin temperature: A normal skin temperature is warm and dry. A cool skin temperature indicates reduced blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
F. Pain: A pain level of 10 on a scale of 0 to 10 indicates severe pain that needs to be managed with appropriate analgesics and nonpharmacological interventions.

- A playpen is a portable enclosure that provides a confined space for a child to play in. It can be useful for keeping a child safe and supervised when the caregiver is busy or needs a break, but it should not be used as a substitute for active play or interaction with the caregiver or others.
- A 2-year-old child is in the developmental stage of toddlerhood, which is characterized by rapid physical, cognitive, social, and emotional growth. Toddlers are curious and eager to learn about the world around them, and they need opportunities to explore, experiment, and manipulate objects and materials. They also need stimulation, guidance, and feedback from their caregivers and peers to develop their language, problem-solving, and social skills.
- Keeping a 2-year-old child in a playpen for long periods of time or to prevent them from getting dirty can have negative effects on their development and well-being. It can limit their physical activity, creativity, and independence, and it can cause boredom, frustration, or resentment . It can also interfere with their atachment and bonding with their caregiver, as well as their self-esteem and self-image.
- Therefore, the practical nurse (PN) should use the statement "Children need time to actively explore their environment" in responding to this concern about using a playpen. This statement reflects the developmental needs and rights of the child, and it encourages the caregiver to provide a more stimulating and supportive environment for the child. It also implies that getting dirty is not a problem, but rather a natural and healthy part of play and learning.

- Therefore, option D is the correct answer, while options A, B, and C are incorrect. Option A is incorrect because it is judgmental and may offend or discourage the caregiver.
Option B is incorrect because it is not true that playpens provide a sense of security for the child, as they may feel isolated or restricted in them.
Option C is incorrect because it is not true that playpens provide a safe environment for a toddler, as they may pose hazards such as entrapment, suffocation, or injury from falling or climbing out of them.
