Skin color that lacks the red-pink tones from decreased hemoglobin in blood is best described as:
Pallor.
Cyanosis.
Jaundice.
Erythema.
The Correct Answer is A
Choice A rationale
Pallor refers to the pale appearance of the skin due to decreased blood flow or decreased hemoglobin levels. It is often seen in conditions such as anemia, where there is a reduced number of red blood cells or hemoglobin, leading to a lack of the red-pink tones normally present in healthy skin.
Choice B rationale
Cyanosis refers to a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. It is often seen in respiratory or cardiovascular conditions where there is a decrease in oxygen levels. Cyanosis does not describe the absence of red-pink tones from decreased hemoglobin.
Choice C rationale
Jaundice refers to a yellow discoloration of the skin and eyes due to elevated levels of bilirubin in the blood. It is often seen in liver conditions or hemolysis. Jaundice is not related to decreased hemoglobin levels or the absence of red-pink tones in the skin.
Choice D rationale
Erythema refers to redness of the skin caused by increased blood flow to the capillaries in the dermis. It is often associated with inflammation, infection, or skin irritation. Erythema indicates increased blood flow, not decreased hemoglobin levels.

Correct Answer is B
Explanation
Choice A rationale
Lateralization to the unaffected ear in Weber's test actually indicates sensorineural hearing loss in the affected ear. This choice is incorrect as it doesn’t describe the correct procedure for the test.
Choice B rationale
The Weber's test involves placing an activated tuning fork in the midline of the skull and asking the patient if the sound is heard more loudly in either ear. This helps determine if there is lateralization, which is key in diagnosing the type of hearing loss. Thus, this is the correct procedure for the test.
Choice C rationale
Placing the tuning fork on the mastoid bone and then over air is actually part of the Rinne test, not the Weber test. This choice is, therefore, incorrect for the Weber test.
Choice D rationale
Similar to Choice C, this process describes the Rinne test, which compares air conduction and bone conduction of sound. This is not the correct method for performing Weber’s test.
Correct Answer is A
Explanation
Choice A rationale
Rhonchi are low-pitched, continuous breath sounds that are often indicative of secretions in the large airways. These sounds may change or clear with coughing, so the nurse should have the patient cough and then auscultate again to reassess the presence of rhonchi.
Choice B rationale
Wheezes are high-pitched, musical sounds heard primarily during expiration. They are caused by narrowed airways, typically due to asthma or other obstructive lung conditions. Wheezes do not usually clear with coughing and require specific treatments to address airway constriction.
Choice C rationale
Crackles are discontinuous, popping sounds heard during inspiration and are associated with fluid in the alveoli, such as in conditions like pneumonia or heart failure. Crackles are not typically cleared by coughing and may persist despite the patient's efforts to clear their airways.
Choice D rationale
Stridor is a high-pitched, harsh sound heard during inspiration, often indicating upper airway obstruction. Stridor is a medical emergency and requires immediate intervention to secure the airway. It does not clear with coughing and signifies a critical respiratory issue. .
