A nurse is interpreting the ECG strip of a client who has bradycardia. Which cardiac components should the nurse identify as the role of the P wave?
Early ventricular repolarization
Atrial depolarization
Slow repolarization of ventricular Purkinje fibers
Ventricular depolarization
The Correct Answer is B
A. Early ventricular repolarization is represented by the T wave, not the P wave.
B. The P wave represents atrial depolarization, which is the electrical activity that triggers the contraction of the atria.
C. Slow repolarization of ventricular Purkinje fibers is represented by the T wave, not the P wave.
D. Ventricular depolarization is represented by the QRS complex, not the P wave.

Correct Answer is A
Explanation
A. Having the child bend at the waist allows the nurse to observe the spine for any abnormal curvature indicative of scoliosis, such as uneven shoulders or a rib hump.
B. Measuring the distance between the knees and the ankles is not a technique used to screen for scoliosis; it is more related to assessing leg length discrepancies.
C. Measuring the length of each leg does not assess for scoliosis but is more relevant for evaluating leg length inequalities.
D. Asking the child to walk across the room is useful for assessing gait and balance but does not directly assess for scoliosis.
Correct Answer is ["A","B","C","D"]
Explanation
A. Cold intolerance: Patients with hypothyroidism often have difficulty regulating body temperature, leading to a heightened sensitivity to cold.
B. Depression: Hypothyroidism can affect mood and cognitive function, often leading to symptoms of depression.
C. Weakness and fatigue: Low thyroid hormone levels can cause significant fatigue and muscle weakness due to a slower metabolism.
D. Constipation: A slowed metabolism can also affect gastrointestinal motility, resulting in constipation.
E. Mental alertness: This is typically not expected in hypothyroid patients. In fact, they may experience cognitive impairments, memory issues, or slowed thinking rather than mental alertness.
