The nurse assesses a client who reports chronic pain with chewing. The nurse should assess which body area to investigate the client's problem further?

A) To check radial pulses: Radial pulses are typically assessed by palpation at the wrist. A gooseneck lamp is not necessary for this task; standard lighting and direct palpation are usually sufficient.
B) To assess pedal pulses: Pedal pulses are assessed by palpation on the top of the foot. A gooseneck lamp is not needed for this purpose, as the lighting conditions are generally adequate for palpation in a well-lit room.
C) To assess jugular filling pressure: Assessing jugular venous pressure (JVP) requires good lighting to clearly see the pulsations in the jugular veins. A gooseneck lamp provides focused and adjustable lighting, which is helpful for this assessment. This ensures accurate observation of the jugular veins and helps in evaluating the severity of heart failure.
D) To auscultate lung sounds: Auscultating lung sounds involves using a stethoscope and does not typically require a gooseneck lamp. Proper lighting is not essential for auscultation, as the focus is on auditory assessment rather than visual inspection.

Rationale:
A) Peripheral Pulses: Peripheral pulses are assessed by palpating the pulse points, such as the radial or dorsalis pedis pulse, to evaluate the strength and regularity of the pulse. This assessment is not related to pressing the skin and observing it for indentation.
B) Skin Temperature: Skin temperature is assessed by palpating the skin with the back of the hand or fingers to detect warmth or coolness. This method does not involve pressing with the thumb and assessing for indentation.
C) Pitting Edema: Pitting edema is assessed by applying pressure to the skin over a bony area, such as the tibia or ankle, and then observing the skin's response after releasing the pressure. The presence of a pit or indentation that remains after the pressure is removed indicates pitting edema, which is a sign of fluid retention.
D) Capillary Refill: Capillary refill is assessed by pressing down on the nail bed or the skin and then observing how quickly the color returns after releasing the pressure. This test measures peripheral circulation and is different from the assessment for pitting edema.
