A nurse is caring for a client who is ambulating for the first time after surgery. Upon standing, the client reports dizziness and faintness. The client’s blood pressure is 90/50 mmHg. What is the name for this condition?
Ambulatory tachycardia
Ambulatory bradycardia
Orthostatic hypertension
Orthostatic hypotension
The Correct Answer is D
Choice A reason: Ambulatory tachycardia is not a recognized condition. Tachycardia (elevated heart rate) may occur with orthostatic changes but does not define the condition. Orthostatic hypotension, marked by a blood pressure drop (90/50 mmHg) upon standing, causes dizziness due to reduced cerebral perfusion from impaired vascular response, making this incorrect.
Choice B reason: Ambulatory bradycardia is not a standard term. Bradycardia (low heart rate) is unrelated to the symptoms of dizziness and low blood pressure (90/50 mmHg) upon standing. Orthostatic hypotension results from inadequate vasoconstriction and reduced venous return, decreasing cerebral blood flow, causing faintness, making this option incorrect.
Choice C reason: Orthostatic hypertension involves elevated blood pressure upon standing, opposite to the client’s 90/50 mmHg. Orthostatic hypotension, characterized by a drop in blood pressure, causes dizziness due to reduced cerebral perfusion from impaired baroreceptor-mediated vasoconstriction. This mismatch in symptoms and blood pressure response makes orthostatic hypertension incorrect.
Choice D reason: Orthostatic hypotension is a drop in blood pressure (e.g., 90/50 mmHg) upon standing, causing dizziness and faintness. It results from inadequate autonomic compensation, reducing venous return and cerebral perfusion. Post-surgical fluid shifts or autonomic dysfunction exacerbate this, impairing brain oxygenation, making this the correct term for the client’s condition.

Correct Answer is C
Explanation
Choice A reason: Labeling the action as libel, a felony, is incorrect, as libel involves defamatory statements, not clinical errors. Negligence relates to failing to meet care standards, not legal defamation. This mischaracterizes the issue, focusing on legal terms irrelevant to the failure to report critical hypertension, per nursing liability.
Choice B reason: While poor interprofessional communication may have contributed, it does not fully capture the negligence. The primary issue is not reporting a critical blood pressure (202/122), which a prudent nurse would address. Communication is secondary to the nurse’s failure to act on a life-threatening finding, per professional standards.
Choice C reason: Failing to act as a prudent nurse under similar circumstances defines negligence, as not reporting 202/122 mmHg endangered the patient, leading to ICU transfer. A reasonable nurse would have notified the provider, preventing harm, aligning with legal and ethical standards of care and accountability.
Choice D reason: Not reassessing blood pressure is relevant but not the core negligence. The primary issue is failing to report the critical reading, which required immediate action. Reassessment alone would not address the urgency of notifying the provider, making this less comprehensive than negligence, per standards.
Correct Answer is B
Explanation
Choice A reason: Dysrhythmia refers to an irregular rhythm, not a specific rate. An apical pulse of 140 indicates a fast rate, not necessarily irregular, so tachycardia is more accurate. Dysrhythmia requires evidence of irregularity, not present here, per cardiac assessment terminology.
Choice B reason: Tachycardia is an apical pulse above 100 bpm, and 140 fits this definition, indicating a rapid heart rate. This requires further investigation for causes like pain or hypoxia, ensuring accurate documentation and intervention, per cardiovascular assessment and clinical terminology standards.
Choice C reason: Bradycardia is a pulse below 60 bpm, not applicable to 140. This rapid rate indicates tachycardia, not a slow heart, requiring different management. Mislabeling as bradycardia could lead to inappropriate care, per cardiac physiology and documentation guidelines.
Choice D reason: A normal pulse is 60-100 bpm, not 140. This rate indicates tachycardia, a pathological finding needing evaluation. Documenting as normal ignores a significant abnormality, risking delayed intervention, per clinical standards for pulse rate assessment and documentation.
