When a nurse obtains an unusually low blood pressure measurement for a client whose blood pressure is generally elevated, she considers the possibility of a problem with her technique. Which of the following sources of error should she consider as a possible cause of the low reading?
Wrapping the cuff too loosely around the client's arm
Measuring blood pressure right after the client's mealtime
Positioning the client's arm above heart level
Deflating the cuff too slowly
The Correct Answer is C
The correct answer is: c. Positioning the client’s arm above heart level.
Choice A: Wrapping the cuff too loosely around the client’s arm
Wrapping the cuff too loosely can lead to an inaccurately high blood pressure reading, not a low one. A loose cuff does not compress the artery properly, causing the device to overestimate the pressure needed to occlude the artery.
Choice B: Measuring blood pressure right after the client’s mealtime
Measuring blood pressure right after a meal can cause a slight increase in blood pressure due to the body’s metabolic response to digestion. This is not a common cause of a low blood pressure reading.
Choice C: Positioning the client’s arm above heart level
Positioning the client’s arm above heart level can lead to an inaccurately low blood pressure reading. When the arm is elevated, the hydrostatic pressure decreases, resulting in a lower reading. This is a well-known source of error in blood pressure measurement.
Choice D: Deflating the cuff too slowly
Deflating the cuff too slowly can cause venous congestion, which may lead to an inaccurately high reading rather than a low one. The standard deflation rate is 2-3 mm Hg per second to ensure accurate measurement.

Correct Answer is D
Explanation
Choice A reason: Putting on sterile gloves is not necessary before palpating the abdomen. Sterile gloves are typically used for procedures that require an aseptic technique, such as inserting a catheter or performing a surgical procedure. Palpation of the abdomen is a non-sterile procedure, and clean gloves are usually sufficient to prevent the transmission of microorganisms.
Choice B reason: Elevating the client's head is not a standard preparatory step before palpating the abdomen. While it may be necessary to adjust the client's position for comfort or to assess certain areas, the head elevation is not specifically related to the palpation process. The client should be in a supine position with knees slightly bent to relax the abdominal muscles, which facilitates palpation.
Choice C reason: Percussion of all four quadrants is part of the abdominal assessment but is not the step that precedes palpation. Percussion is used to assess the size and density of abdominal organs, detect the presence of fluid or gas, and evaluate tenderness. However, the correct sequence of abdominal assessment is inspection, auscultation, percussion, and then palpation.
Choice D reason: Auscultating bowel sounds is the correct action before palpating the abdomen. This is because palpation can alter bowel motility, which may change the sounds heard. Auscultation should be performed after inspection and before percussion and palpation to obtain an accurate assessment of bowel activity. Normal bowel sounds range from 5 to 30 per minute and are characterized by clicks and gurgles.
Correct Answer is D
Explanation
Choice A reason: The FACES pain scale is commonly used for children who are able to select a face that best describes their pain. However, this scale is not suitable for a 6-month-old infant post-myringotomy, as infants of this age cannot verbally communicate or reliably choose a face to represent their pain level.
Choice B reason: The Visual Analog Scale (VAS) is typically used for older children and adults who can understand and indicate their level of pain by marking a point on a line. This scale is not appropriate for infants due to their developmental stage and inability to communicate or understand the concept of the scale.
Choice C reason: The Oucher pain scale includes both a photographic scale with pictures of children's faces showing different levels of pain and a numerical scale. While it is designed for children aged 3 to 12 years, it is not suitable for infants, as they cannot verbally express their pain or point to a photograph to indicate their pain level.
Choice D reason: The FLACC scale, which stands for Face, Legs, Activity, Cry, and Consolability, is an appropriate choice for assessing pain in infants and young children who are non-verbal. It involves observing specific behaviors and assigning a score from 0 to 2 for each category, resulting in a total score between 0 and 10. This observational tool allows healthcare providers to assess pain levels based on the infant's behavior and physiological responses.
