The nurse is caring for a client who has just been diagnosed with sinus bradycardia. Indicate with an X the area on the illustration where the heartbeat's electrical impulse is initiated.
Correct Answer: A
Rationale: The sinoatrial (S
A) node, located in the right atrium, initiates the heartbeat's electrical impulse. (

Question 2 of 5
The nurse is preparing to administer heparin subcutaneously. Which needle size is most appropriate?
Correct Answer: C
Rationale: A 25-gauge, 5/8-inch needle is appropriate for subcutaneous injections like heparin to minimize tissue trauma.
Question 3 of 5
Which assessment findings provide the nurse with the best indications that a client's tracheostomy needs suctioning? Select all that apply.
Correct Answer: C,E,F
Rationale: Noisy respirations, coughing up sputum, and a low pulse oximeter reading (87%) indicate airway obstruction or secretions that require suctioning. A slowed pulse rate, cool/moist skin, and elevated respiratory rate are not specific indicators for suctioning.
Question 4 of 5
The nurse is assessing a client with suspected dehydration. Which finding supports this diagnosis? Select all that apply.
Correct Answer: A,B,C,E
Rationale: Sunken eyes, increased thirst, tachypnea, and poor skin turgor are signs of dehydration; bradycardia is not.
Question 5 of 5
An 8-year-old is sent to the school nurse when the teacher notices recurrent staring episodes with frequent blinking. Shortly after an episode, the student is alert and oriented and responds appropriately. Which action by the school nurse is most appropriate?
