A nurse is teaching a client who has pernicious anemia to self-administer nasal cyanocobalamin. Which of the following information should the nurse include in the teaching?

A. For assessing pain in a 4-year-old child following an orthopedic procedure, the nurse should use the FACES pain scale.
The FACES pain scale uses a series of faces with varying expressions, from smiling to crying, to help children express their level of pain. Children are asked to point to the face that best matches how they feel. This scale is particularly useful for young children who may not have the verbal skills to describe their pain accurately using words or numbers.
B. Word-graphic
Explanation: The word-graphic pain scale typically uses a combination of words and drawings to assess pain, making it more suitable for children who are slightly older and can understand simple words and concepts.
C. Numeric
Explanation: The numeric pain scale involves asking the child to rate their pain on a scale from 0 to 10. This scale is more appropriate for older children who can understand and assign numerical values to their pain intensity.
D. CRIES
Explanation: The CRIES pain scale is often used for assessing pain in newborns and infants up to 6 months old. It focuses on crying, oxygen saturation, vital signs, and facial expressions.

A. Another formulation of potassium should be given IV: The type of potassium formulation isn't the issue in this scenario.

B. Potassium chloride should be diluted in dextrose 5% in water: While potassium chloride can be administered in different solutions, the primary concern here is the infusion rate, not the specific diluent.

C. The client should be treated by giving potassium by IV bolus: The concern here is the rate of administration, not the route. Potassium is commonly administered through an IV infusion rather than a bolus due to the risk of cardiac arrhythmias associated with rapid administration.

D. A nurse is caring for a client who is to receive potassium replacement. The nurse should clarify the prescription with the provider because the potassium infusion rate is too rapid.

The prescription indicates that the client should receive potassium chloride 30 mEq in 0.9% sodium chloride 100 mL IV over 30 minutes. This rate of administration is too fast for potassium replacement and could lead to potentially serious complications, such as hyperkalemia or cardiac arrhythmias. The typical recommended rate for potassium replacement is 10-20 mEq/hour, and this prescription exceeds that range.
