Answer to Question 1
ANS: D
The probe of a pulse oximeter uses infrared light, which can damage skin. The nurse should move the probe and inspect the skin underneath it per facility policy or at least once a day. Biomedical equipment has an inspection and maintenance schedule, and the nurse should not have to ask to have the machine inspected before use. Oximeters are not zeroed. The machine should stay plugged in whenever possible, but batteries allow for portability.
Answer to Question 2
ANS: C
The parent needs an objective, factual rationale for feeding the child what to the parent seems to be too much food. Critically ill children have higher metabolic rates and need more high-quality calories for healing. The nurse should not convey worry about the child's weight, nor should the nurse state that the child is malnourished unless that is the case. There is no information in the stem of the question that suggests this. Stating that the child won't get fat is playing into the parent's concern about weight without giving any objective reason for the increased intake.
