Answer to Question 1
C
If a peripheral pulse distal to an injured or treated area of an extremity feels weak on palpation, the volume of blood reaching tissues below the affected area may be inadequate, and surgical intervention may be necessary. A full bounding pulse is an indication of increased volume. When the pulse wave reaches a peripheral artery, you can feel it by palpating the artery lightly against underlying bone or muscle. The pulse is the palpable bounding of the blood flow. The usual range for adults is 60 to 100 beats per minute.
Answer to Question 2
C
The suction catheter should not be inserted during swallowing because it will most likely enter the esophagus. Insert during inhalation because the epiglottis is open. The patient should be hyperoxygenated before suctioning. The oxygen flow rate can be increased on the face mask, and the patient can deep-breathe slowly to accomplish this. The catheter should be inserted along the natural course of the naresslightly slanted downward. In adults, the catheter is inserted about 20 cm or 8 inches.
