behavior in infants and does not necessarily warrant further investigation, as they often experience stranger anxiety as a normal part of their social development. Babbling "mama" and "dada" is a typical language development milestone for a 9-month-old, and preferring crawling over walking is within the expected range of developmental variations, as the timeline for motor skill development can vary among infants.(See The Aging Process, Developmental Stages, and Transitions ) 3. The LPN examines the client’s ECG strip attached to this question. The LPN identities this cardiac rhythm as which of the following?

A.​ Bradycardia B.​ Atrial fibrillation C.​ Ventricular tachycardia D.​ Atrial flutter

Correct Response: D Explanation: The correct answer is (D) , Atrial flutter. This rhythm is characterized by a regular, saw-tooth pattern of atrial activity, often referred to as "F-waves." Atrial flutter typically presents with an atrial rate higher than the ventricular rate, creating a characteristic appearance on the ECG. (A) , bradycardia, is incorrect because atrial flutter is associated with a rapid atrial rate, not a slow one. (B) , atrial fibrillation, is incorrect as atrial fibrillation typically displays irregular and chaotic atrial activity, differing from the organized pattern seen in atrial flutter. (C) , ventricular tachycardia, is also incorrect because the rhythm on the ECG primarily involves atrial activity, and ventricular tachycardia would present with a different ECG pattern primarily involving the ventricles. Therefore, the correct identification of the rhythm in this case is atrial flutter (D) . (See Atrial Arrhythmias ) 4. The LPN enters the room of a client who is having a tonic-clonic seizure. Which action should the LPN take first? A.​ Elevate the head of the bed. B.​ Prepare Lorazepam for administration. C.​ Secure the airway. D.​ Place a tongue depressor in between the client’s teeth. Correct Response: C Explanation: The correct answer is (C) , as the first priority when a client is experiencing a seizure is to secure the airway. Ensuring a clear airway is crucial to prevent respiratory compromise and maintain oxygenation during the seizure episode. This involves repositioning the client to prevent the tongue from
