A nurse is performing general inspection and measuring vital signs on a client during a routine physical exam. Which of the following actions should the nurse take to ensure an accurate assessment? (Select all that apply)
Use an appropriately sized cuff.
Ensure the client has been seated and rested for at least 5 minutes before measuring blood pressure.
Count respirations for 30 seconds and multiply by 2, even if the pattern is irregular.
Document the client's appearance, posture, and breathing pattern during general inspection.
Position the client's arm above heart level while measuring blood pressure.
Remove clothing that interferes with cuff placement prior to taking the blood pressure.
Correct Answer : A,B,D,F
Choice A reason: Selecting a blood pressure cuff of the correct size is fundamental for diagnostic accuracy. A cuff that is too small will result in a falsely elevated reading, while a cuff that is too large will provide a falsely low reading. The bladder should encircle 80% to 100% of the arm circumference.
Choice B reason: Physiological stabilization is required to obtain a true baseline blood pressure. Physical activity or emotional stress can transiently elevate sympathetic nervous system activity. Allowing the patient to sit quietly for at least 5 minutes ensures that the cardiovascular system is at rest, preventing white-coat hypertension or exertion-related errors.
Choice C reason: Inaccurate measurement occurs if irregular respiratory patterns are extrapolated. If a client exhibits an irregular rhythm, tachypnea, or bradypnea, the nurse must count the respirations for a full 60 seconds. Multiplying a 30-second count by 2 can miss significant pauses or variations in depth, leading to clinical misinterpretation.
Choice D reason: General inspection provides a qualitative "snapshot" of the patient’s health status. Documenting physical appearance, body habitus, posture, and respiratory effort allows the clinician to identify signs of distress, nutritional status, or neurological deficits. These observations complement quantitative vital signs to form a comprehensive clinical picture of the patient.
Choice E reason: Correct limb positioning is vital for hydrostatic pressure balance. The arm should be supported at the level of the right atrium. If the arm is positioned above heart level, the blood pressure reading will be falsely low; conversely, if the arm is below heart level, the reading will be falsely high.
Choice F reason: Placing a blood pressure cuff over thick or restrictive clothing can interfere with the acoustic or oscillometric detection of arterial pulsations. Removing such barriers ensures that the cuff makes direct contact with the skin or a very thin layer, allowing for precise transmission of Korotkoff sounds or pressure changes.

Correct Answer is C
Explanation
Choice A reason: Subjective data consists of information provided by the patient that cannot be independently verified by the healthcare provider. This typically includes the patient's internal feelings, perceptions, or descriptions of symptoms, such as "I feel hot" or "My skin feels itchy," which are not directly measurable by the nurse.
Choice B reason: Reported data is a subset of subjective information where the patient or a family member recounts past events or symptoms. While important for medical history, it lacks the immediate, verifiable nature of physical findings gathered by a clinician through direct observation or diagnostic tools during the clinical encounter.
Choice C reason: Objective data refers to measurable and observable signs obtained through the senses or diagnostic instruments. Assessing skin temperature (warm), moisture (dry), and color (flushed) through inspection and palpation constitutes objective findings because any trained clinician can observe and verify these physical characteristics during an assessment.
Choice D reason: Emotional data pertains to the psychological or affective state of the patient, such as anxiety, depression, or fear. While a flushed face can sometimes be a physiological manifestation of an emotion like embarrassment, the physical description itself remains a clinical sign rather than an emotional interpretation.
Correct Answer is B
Explanation
Choice A reason: Recording objective findings is the definition of the physical examination, not the Review of Systems (ROS). Objective findings are observable and measurable data, such as blood pressure or lung sounds, whereas the ROS is a subjective component of the health history based on the client's reports.
Choice B reason: The Review of Systems (ROS) is a systematic method for collecting subjective data about the client's past and current health status across all major body systems. It helps identify symptoms that the client may have forgotten to mention and provides a comprehensive overview of the client's functional health.
Choice C reason: A statement describing the overall health state is usually referred to as a "General Survey" or a "Reason for Seeking Care." While the ROS contributes to this understanding, it is far more detailed, specifically broken down by physiological systems to ensure no clinical symptoms are overlooked during the history.
Choice D reason: Documentation of the problem as described by the patient is typically called the "Chief Complaint" or "History of Present Illness." While the ROS includes patient-described symptoms, it is a broader screening tool covering the entire body, whereas the Chief Complaint focuses on the specific reason for the visit.
