Which of the following techniques is correct when obtaining a patient's blood pressure?

Correct Answer: B

Rationale: Correct BP technique includes ensuring legs are uncrossed to avoid falsely elevated readings from vascular compression. Voiding first isn't required unless bladder distension affects comfort. Talking during inflation distracts and may alter pressure. Averaging readings is recommended for diagnosis, not routine checks. Choice B is correct as a single, critical technique per AHA guidelines, ensuring accuracy. Note: A and D are also valid in broader contextsvoiding reduces discomfort, averaging enhances reliabilitybut B is a fundamental, immediate step nurses must ensure during measurement to prevent common errors, making it the prioritized answer here.

Correct Answer: D

Rationale: Tympanic thermometers measure ear canal temperature , reflecting core readings via the tympanic membrane. Oral and rectal are for different devices. Forehead is for temporal thermometers. Choice D is correct, per the explanation and manufacturer guidelines, ensuring accurate placement by aligning with the eardrum for reliable, non-invasive core temperature assessment.

Correct Answer: B

Rationale: The sinoatrial node regulates pulse rate and force as the heart's pacemaker, per the answer key. The thermoregulatory center controls temperature. Atria and valves don't set rhythm. Chemoreceptors adjust respiration. The SA node's electrical impulses drive heartbeats, a critical nursing concept for understanding pulse dynamics in health assessments.
