What is the rate on the rhythm strip in the image below?
90
110
73
50
The Correct Answer is A
A. To determine the heart rate from a rhythm strip, you can count the number of R-R intervals in a set time frame (typically 6 seconds) and multiply by 10 to convert to beats per minute. If the rhythm is regular, you can also use the 300 method by dividing 300 by the number of large squares between R waves. In this case, the rate is calculated to be 90 beats per minute.
B. A heart rate of 110 beats per minute would be classified as tachycardia and is not supported by the observed intervals.
C. A heart rate of 73 beats per minute would be a normal resting heart rate but does not match the calculation from the rhythm strip.
D. A heart rate of 50 beats per minute would indicate bradycardia, which is not reflected in this rhythm strip.

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 B
Explanation
A. Auscultating the area may not provide information about the dorsalis pedis pulse, which is a palpated pulse.
B. Using Doppler ultrasonography is the most appropriate next step to locate the dorsalis pedis pulse if it cannot be palpated, as it provides a non-invasive way to detect blood flow.
C. While documenting the absence of the pulse is necessary, it should be done after attempts to locate the pulse have been made.
D. It is not immediately necessary to ask a provider to assess the pulse; the nurse can use Doppler ultrasonography first to gather more information.
