Mr. Cook requires medication for nausea. Compazine 10mg po q 4hrs prn ordered. You have Compazine 5-mg tablets available. How many tablets will you administer per dose?

A. Positioning the bell very lightly over the patient's sternum. The bell is best for low-pitched sounds like murmurs, but heartbeats (especially S1 and S2) are better heard with the diaphragm over the apex of the heart, not the sternum.
B. Placing the diaphragm firmly against the patient's skin. The diaphragm is designed to pick up high-pitched sounds like the normal S1 and S2 heart sounds. Pressing firmly helps eliminate external noise and improves sound clarity.
C. Utilizing a stethoscope with the longest possible tubing. Longer tubing can reduce sound transmission quality. Shorter tubing (about 14-18 inches) provides clearer sound.
D. Making sure that the earpieces fit loosely in the nurse's ear canals. Earpieces should fit snugly, not loosely, to ensure optimal sound conduction and block external noise.

A. Ask the client to take deep breaths. Deep breathing can help relax the anal sphincter, but if resistance is already encountered, forcing the thermometer further could cause injury.
B. Remove the thermometer and reinsert more forcefully. Forcing the thermometer can cause damage to the rectal mucosa, leading to pain, bleeding, or even perforation.
C. Apply mild pressure to advance. Any resistance suggests a possible obstruction, such as stool or anatomical issues. Applying pressure could cause harm, so the thermometer should not be advanced further.
D. Remove the thermometer immediately. If resistance is encountered, the safest action is to withdraw the thermometer to prevent injury. The nurse should reassess the situation and consider alternative temperature measurement methods.
