To accurately take a client's blood pressure, which action by the nurse is most important?

Choice A rationale:

This option is incorrect. Tachypnea refers to abnormally fast breathing, typically defined as a respiratory rate higher than 20 breaths per minute in adults. It is the opposite of the condition described in the question, where the respiratory rate has fallen below 10 respirations per minute.

Choice B rationale:

This option is incorrect. Apnea refers to the absence of breathing, often resulting from a temporary cessation of airflow to the lungs. It is characterized by the complete absence of respiratory movements and sounds, which is different from the situation described in the question where the client is breathing at a very slow rate.

Choice C rationale:

Bradypnea, or abnormally slow breathing, is the correct answer in this case. It is defined as a respiratory rate lower than the normal range, which is typically between 12 to 20 breaths per minute in adults. Bradypnea can be caused by various factors, including drug overdose, neurological disorders, or metabolic imbalances. In this scenario, the client's slow respiratory rate (below 10 respirations per minute) indicates bradypnea.

Choice D rationale:

This option is incorrect. Eupnea refers to normal breathing, where the rate and depth of respirations are within the normal range. It does not describe the condition of the sedated client in the question, who is experiencing abnormally slow breathing (bradypnea)
