A nurse is caring for a client who is taking antihypertensive medication and is moving from a supine to a sitting position.
Which of the following findings should indicate to the nurse that the client is experiencing orthostatic hypotension?
The client's heart rate increases by 10/min.
The client's diastolic blood pressure increases by 10 mm Hg.
The client reports heart palpitations.
The client's systolic blood pressure decreases by 25 mm Hg.
The Correct Answer is D
Choice A rationale:
An increase in heart rate by 10 beats per minute when moving from a supine to a sitting position is a normal physiological response to compensate for decreased venous return and maintain cardiac output. This response does not indicate orthostatic hypotension.
Choice B rationale:
An increase in diastolic blood pressure by 10 mm Hg when moving from a supine to a sitting position is a normal response to compensate for the effects of gravity on blood flow. It helps maintain perfusion to vital organs and does not indicate orthostatic hypotension.
Choice C rationale:
Heart palpitations can occur due to various reasons, including anxiety or arrhythmias, but they are not specific signs of orthostatic hypotension. This symptom alone does not confirm the presence of orthostatic hypotension.
Choice D rationale:
A decrease in systolic blood pressure by 25 mm Hg or more when moving from a supine to a sitting position indicates orthostatic hypotension. Orthostatic hypotension is defined as a drop in systolic blood pressure of 20 mm Hg or more or a drop in diastolic blood pressure of 10 mm Hg or more within 3 minutes of standing up. This condition can cause dizziness, lightheadedness, or fainting and can be a side effect of antihypertensive medications or other underlying medical conditions.

Correct Answer is ["B","C","E","F"]
Explanation
A. Attends school regularly: While attending school regularly is important, it is not an immediate concern that requires follow-up compared to the other more pressing issues related to the traumatic event and the client's mental well-being.
B. Caregiver reporting client acting differently than usual: This finding requires immediate follow-up because it indicates a change in the client's behavior and could be indicative of emotional distress or mental health issues, especially considering the recent traumatic event they experienced.
C. Witnessing their family's death: Witnessing the death of family members in a traumatic event like a tornado is a significant and potentially traumatizing experience that requires immediate follow-up and support.
D. Heart rate 99/min: While a heart rate of 99/min is slightly elevated, it is not a critical finding that requires immediate follow-up in this context. The other findings are more relevant to the client's psychological well-being.
E. Smoking marijuana to clear their mind: The client's use of marijuana to cope with their thoughts and feelings should be addressed promptly, as it could indicate maladaptive coping mechanisms or potential substance abuse.
F. Client experiences nightmares: Experiencing nightmares could be a symptom of post-traumatic stress disorder (PTSD) or other mental health concerns related to the traumatic event.
G. BP 122/80 mm Hg: A blood pressure of 122/80 mm Hg is within a normal range and is not a cause for immediate concern.
H. Startles easy during thunderstorm: While startle responses can be related to anxiety, this specific finding is not as pressing as the client's reported coping mechanisms and traumatic experiences.
