Which of the following is the correct procedure for measuring an adult's blood pressure using a manual sphygmomanometer?

Place the stethoscope over the patient's chest and listen for the first sound to appear

Inflate the cuff to 140 mmHg and release it quickly while palpating the radial pulse

Inflate the cuff to 100 mmHg, then slowly deflate while listening for Korotkoff sounds

Inflate the cuff to 30 mmHg above the patient's estimated systolic pressure, then slowly deflate and listen for Korotkoff sounds

Answer and Explanation

The Correct Answer is D

Rationale:

A. Placing the stethoscope over the patient’s chest and listening for the first sound is incorrect because blood pressure is measured by auscultating the brachial artery in the antecubital fossa, not the chest.

B. Inflating the cuff to 140 mmHg and releasing it quickly while palpating the radial pulse is incorrect because 140 mmHg may not exceed the patient’s systolic pressure, and rapid deflation can lead to an inaccurate reading.

C. Inflating the cuff to 100 mmHg and slowly deflating while listening for Korotkoff sounds is incorrect because in many adults this pressure may not be sufficient to occlude the brachial artery, which can result in a falsely low measurement.

D. Inflating the cuff to 30 mmHg above the patient’s estimated systolic pressure and slowly deflating while listening for Korotkoff sounds is correct. The cuff should be placed on the bare upper arm at heart level, and the stethoscope positioned over the brachial artery. The first Korotkoff sound heard indicates systolic pressure, and the disappearance of sound indicates diastolic pressure. Inflating above the estimated systolic pressure ensures the artery is fully occluded, allowing for an accurate reading.

Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"C"},"E":{"answers":"A"}}

Explanation

Rationale:

Temperature: Worsened. Increased from 38.2°C to 38.6°C, indicating a slight rise in fever.
Pulse oximetry: Improved. Oxygen saturation improved from 85% to 95% after oxygen therapy and interventions.
Respiratory rate: Improved. Rate decreased from 32/min to 22/min, showing reduced work of breathing.
Blood pressure: Unchanged. BP remained stable at 112/56 mm Hg.
Mucous membrane color: Improved. Color changed from pale to pink, indicating improved oxygenation and perfusion.

A. Moveable B. Smooth C. Non-tender D. Hard E. Fixed

Correct Answer is ["D","E"]

Explanation

Rationale:

A. Lymph nodes that are freely moveable under the skin are typically normal. Mobility indicates that the node is not infiltrated by fibrotic tissue or malignant cells. Moveable nodes may shift slightly during palpation and are usually soft or rubbery.

B. Smooth lymph nodes are generally normal. Irregular, nodular, or spiculated nodes are more concerning for pathology. Smoothness alone does not indicate abnormality.

C. Non-tender lymph nodes are often normal, particularly if they are small and soft. Tenderness is usually associated with acute infections, such as localized cellulitis or mastitis. Therefore, non-tender nodes in isolation are not considered abnormal.

D. Hard lymph nodes are abnormal. Hardness suggests that the node may be infiltrated with malignant cells or fibrotic tissue, which can occur in breast cancer metastasis or chronic infections. Hard nodes are less compressible and may be associated with an irregular surface.

E. Fixed, immobile lymph nodes are also abnormal. Normal nodes are freely movable; when nodes are adherent to surrounding tissues, it can indicate malignancy, fibrosis, or metastatic spread. Fixed nodes do not shift easily with palpation and require prompt medical evaluation.
