NNAAP California Nurse Aides - Blogs Sample Questions

Attaching a sensor to the finger to measure oxygen concentration is called what?

Correct Answer:
pulse oximetry
the correct answer to the question "attaching a sensor to the finger to measure oxygen concentration is called what?" is pulse oximetry.

pulse oximetry is a non-invasive method commonly used to monitor the oxygen saturation of a patient’s blood. a pulse oximeter is a small, clip-like device that attaches to a body part, usually a fingertip or earlobe, to measure the amount of oxygen carried in the body. this painless test can rapidly detect even small changes in how efficiently oxygen is being carried to the extremities furthest from the heart, such as the legs and the arms, which might be harder to detect with other methods.

the device works by shining light through the skin to the blood beneath. it uses two wavelengths of light, red and infrared, which are absorbed differently by oxygen-rich hemoglobin and oxygen-poor hemoglobin present in the blood. the ratio of how much light is absorbed by each type of hemoglobin is calculated by the device, thereby giving a reading of oxygen saturation levels, often displayed as a percentage. a normal reading typically falls between 95% and 100%, indicating that most of the hemoglobin is saturated with oxygen.

pulse oximetry is vital during surgeries or other medical procedures that might affect blood oxygen levels, especially for individuals with ongoing heart and lung conditions. it is also routinely used in emergency settings or critical care to monitor patients and assess their need for supplemental oxygen. additionally, pulse oximeters are used in outpatient settings for patients with conditions like chronic obstructive pulmonary disease (copd) or congestive heart failure to monitor their health status.

while pulse oximetry is a useful and effective tool for measuring blood oxygen levels, it is not a substitute for other tests like arterial blood gas tests, which provide more detailed information including blood ph and carbon dioxide levels. however, because pulse oximetry is quick, straightforward, and noninvasive, it is often the first choice for continuously monitoring an individual's oxygen saturation.

Brushing a patient’s hair may do all of the following EXCEPT:

Correct Answer:
decrease hirsutism


brushing a patient's hair is a common practice in healthcare and personal grooming that provides several benefits to the hair and scalp. however, it is important to understand what brushing can and cannot do in terms of hair health and conditions. one such misunderstanding is the effect of brushing on hirsutism.

hirsutism refers to an abnormal growth of hair on a person’s face and body, especially on a woman, that is typically coarse and dark. it is often the result of a hormonal imbalance, such as excess androgens (male hormones), or from conditions like polycystic ovary syndrome (pcos). hirsutism is related to follicle sensitivity to hormones, not to the conditions that can be altered by brushing.

brushing the hair has several benefits. it can help distribute natural scalp oils along the hair shaft, which enhances hair shine and health. this oil distribution is crucial for maintaining moisture balance in the hair and preventing dryness. additionally, regular brushing can help to increase blood flow to the scalp. this increased circulation brings more nutrients and oxygen to the hair follicles, which can promote healthier hair growth and improve scalp health.

another benefit of regular brushing includes the prevention of matting and tangling. especially in patients with long hair, tangles can lead to hair breakage and loss when not properly managed. brushing helps to keep the hair smooth and manageable, reducing the risk of knots that can result in damage when they are forcibly removed.

however, while these benefits support overall hair and scalp health, they do not impact the growth patterns influenced by hormones, such as those seen in hirsutism. brushing does not decrease hirsutism as it does not affect hormone levels or the sensitivity of hair follicles to hormones. therefore, while brushing is beneficial for many aspects of hair care, it cannot be used as a treatment method for hirsutism. effective treatments for hirsutism often involve hormonal management through medications, laser therapy, or other medical interventions prescribed by healthcare professionals.
