Understanding how to calculate time, speed and distance questions is essential for safe navigation. 10 knots is a short way to say 10 nautical miles per hour. A nautical mile is longer than a statute mile which is used for navigating on land.One nautical mile equals 1.15 statue miles.nderstanding how to calculate time, speed and distance questions is essential for safe navigation. 10 knots is a short way to say 10 nautical miles per hour.

Impaired Skin integrity. 1. Assess site of skin impairment and determine etiology (e.g., acute or chronic wound, burn, dermatological lesion, pressure ulcer, skin tear) (Krasner, Sibbald, 1999). Prior assessment of wound etiology is critical for proper identification of nursing interventions (van Rijswijk, 2001).
Causes. The most common cause of pressure wounds and skin integrity issues is constant pressure from squeezing skin against a surface (such as a bed or wheelchair) which can reduce blood flow to the area and cause injury. This typically happens if someone remains in one position for a prolonged period of time.
