A nurse is teaching the mother of a child who has cystic fibrosis and has a prescription for pancreatic enzymes three times per day. Which of the following statements indicates that the mother understands the teaching?

For a child with von Willebrand disease experiencing a nosebleed, the nurse should instruct the parent to have the child sit with their head tilted forward slightly (not backward) to prevent blood from flowing down the throat. Applying direct pressure to the nostrils with fingers or using a clean cloth for about 10 minutes will help stop the bleeding.
Option B (applying ice at the base of the nose) is not recommended because ice can cause vasoconstriction, potentially prolonging bleeding in individuals with bleeding disorders.
Option C (placing the child in a supine position with a pillow under the back) is also not recommended, as this can lead to blood flowing down the throat, increasing the risk of aspiration.
Option D (placing the child in a sitting position with her head tilted back) should be avoided as it can lead to blood flowing into the throat and potentially being swallowed or aspirated. This position is generally discouraged for nosebleeds.

D. A client's blood pressure changes from 112/60 mm Hg to 90/54 mm Hg when standing.
A significant drop in blood pressure when changing positions from lying to standing may indicate orthostatic hypotension, which can be a sign of dehydration, blood loss, or other underlying medical issues. This can be a cause for concern, especially if the client is an adolescent, as it may lead to decreased perfusion of vital organs and may require immediate medical attention.

The other options are as follows:
A. A client who has a burn injury to an estimated 5% of his leg and is crying - While it's essential to assess and address the client's pain and comfort, this finding does not indicate an immediate need for medical attention. Pain management and wound care can be addressed based on the severity of the burn and the client's pain level.
B. A client who has an ankle fracture reports a pain level increase from 3 to 5 after initial ambulation - This finding is concerning, and the nurse should notify the provider to reassess pain management and evaluate for potential complications related to the fracture. However, it may not require immediate medical attention unless there are signs of severe pain or complications.
C. A client who is 1 day postoperative and has a temperature of 37.5° C (99.5° F) - A slight increase in temperature in the immediate postoperative period may not be unusual and can be attributed to the normal inflammatory response after surgery. The nurse should continue monitoring the client's temperature and report any further changes or additional signs of infection or complications to the provider.
Overall, while all findings should be addressed and managed appropriately, the significant drop in blood pressure (option D) should be reported immediately due to the potential implications for the client's overall health and well-being.
