Where should Charlotte, an EKG tech, place the leads for a resting EKG on a patient who is immobile and in a fetal position?

Back

On the patient's back

Answer explanation

In a fetal position, placing the leads on the patient's back allows for proper contact with the skin and accurate readings, as the standard sites may not be accessible. Thus, the correct choice is to place the leads on the patient's back.

Ava is a pediatric nurse checking the vital signs of a 2-year-old patient. What would be the expected pulse rate for this patient?

Back

120

Answer explanation

The expected pulse rate for a 2-year-old is typically around 120 beats per minute. This is higher than the rates for older children and adults, making 120 the correct choice.

During a medical training session, Harper is learning how to measure heart rhythms. How many seconds long should a rhythm strip be to accurately identify rhythm and rate?

Back

6 seconds

Answer explanation

A 6-second rhythm strip is ideal for accurately identifying rhythm and rate, as it allows for a sufficient number of cycles to analyze the heart's activity effectively.

During a medical training session, Aiden is learning about the correct placement of ECG leads. What is the correct placement for leads V7, V8, and V9?

Back

Evenly spaced on the back between the axillary line and the vertebral column at the fifth intercostal space

Answer explanation

Leads V7, V8, and V9 are placed evenly spaced on the back, specifically between the axillary line and the vertebral column at the fifth intercostal space, which is the correct anatomical location for these leads.

During a clinical skills class, Isla is learning about infection control practices. Which of the following recommendations should she follow to ensure proper infection control in health care settings? Artificial nails should be no longer than 1.27 cm (0.5 in) in length, Use an alcohol-based hand rub if there is visible contamination on the hands, Remove soiled gloves prior to touching uncontaminated surfaces, Wear the same gloves while performing different procedures on the same patient

Back

Remove soiled gloves prior to touching uncontaminated surfaces

Answer explanation

Removing soiled gloves before touching uncontaminated surfaces is crucial to prevent cross-contamination. The other options do not align with proper infection control practices.

Front

Avery, an EKG tech, notices that a patient has gone into ventricular tachycardia. What should Avery do first?

Back

Notify a licensed practitioner to evaluate the patient.

Answer explanation

In cases of ventricular tachycardia, the first priority is to notify a licensed practitioner for evaluation. This ensures timely medical intervention, which is crucial for patient safety.

Front

Avery is monitoring a patient's vital signs and gets a reading of 88% on a pulse oximetry reading. What term describes the patient's condition?

Back

Hypoxemia

Answer explanation

A pulse oximetry reading of 88% indicates low oxygen saturation in the blood, which is termed hypoxemia. This condition signifies inadequate oxygen levels, making 'Hypoxemia' the correct choice.

Front

During a clinical rotation, Olivia observes that her patient's respiration variations correlate with the EKG tracing. What irregularity does this indicate?

Back

Sinus dysrhythmia

Answer explanation

Sinus dysrhythmia is characterized by variations in heart rate that correlate with respiration. This indicates a normal physiological response, unlike sinus arrest or tachycardia, which do not show this correlation.

Front

Ava is reviewing the EKG tracing of a patient with ventricular hypertrophy. Which findings would she expect?

Back

Increased amplitude of the QRS complex

Answer explanation

In ventricular hypertrophy, the heart muscle thickens, leading to increased electrical activity. This is reflected in the EKG as an increased amplitude of the QRS complex, indicating stronger ventricular depolarization.

Front

Ethan is experiencing heart palpitations. What intervention would you expect a provider to prescribe for him?

Back

Holter monitor

Answer explanation

A Holter monitor is a portable device that records heart activity over 24-48 hours, making it ideal for diagnosing the cause of heart palpitations. Other options do not directly address the monitoring of palpitations.
