How should the nurse identify the rhythm shown in the diagram?
ventricular tachycardia
asystole
normal sinus rhythm
ventricular fibrillation
The Correct Answer is A
A. Ventricular tachycardia: Ventricular tachycardia (VT) is identified by a regular, fast rhythm with wide QRS complexes, typically without visible P waves. This rhythm often appears as consecutive, large, uniform waves, which is consistent with what is seen in the diagram.
B. Asystole: Asystole is characterized by a flat line, indicating no electrical activity, which is not present in this strip.
C. Normal sinus rhythm: Normal sinus rhythm would show identifiable P waves, a normal QRS complex, and a regular rate, which are not observed here.
D. Ventricular fibrillation: Ventricular fibrillation appears as chaotic, irregular waveforms with no clear QRS complexes or organization, which does not match the rhythm shown.

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.
Correct Answer is D
Explanation
A. Bradypnea (slow breathing) may occur in various conditions but is not a defining characteristic of cyanosis.
B. A pale reddish color in the skin is not consistent with cyanosis, which indicates a lack of oxygen in the blood.
C. Somnolence (drowsiness) may be present in some patients, but it is not a specific finding related to cyanosis.
D. Mottled blue color in the skin is a classic sign of cyanosis, indicating inadequate oxygenation of the blood, especially in the extremities or areas with poor circulation.
