A nurse is auscultating the breath sounds of a client who has chronic obstructive pulmonary disease.
When the client exhales, the nurse hears continuous high-pitched whistling sound.
The nurse should document this as?

Rhonchi.

Stridor.

Wheezes.

Crackles.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Rhonchi are low-pitched, coarse sounds typically heard during expiration, associated with secretions in large airways, not high-pitched continuous sounds.

Choice B rationale

Stridor is a high-pitched sound heard during inspiration, typically indicating upper airway obstruction.

Choice C rationale

Wheezes are continuous high-pitched whistling sounds heard during expiration, common in conditions like chronic obstructive pulmonary disease, where airway narrowing is present.

Choice D rationale

Crackles are discontinuous sounds heard during inspiration, usually associated with fluid in the lungs or alveolar opening, not continuous high-pitched sounds. .

Correct Answer is D

Explanation

Choice A rationale

While individuals aged 19 to 30 years are generally at a lower risk for malignant melanoma compared to older adults, melanoma can still occur at any age, especially with certain risk factors. However, age alone does not significantly increase the risk of developing malignant melanoma without additional risk factors.

Choice B rationale

Hair color has minimal impact on the risk of developing malignant melanoma. Although individuals with fair skin and light hair have a higher risk of sunburn and subsequent melanoma, having dark hair does not significantly reduce the risk compared to other factors.

Choice C rationale

Female gender does not inherently increase the risk of developing malignant melanoma. Both males and females are at risk, although certain lifestyle factors and behaviors, such as sun exposure, can influence individual risk levels regardless of gender.

Choice D rationale

A history of repeated sunburn significantly increases the risk of developing malignant melanoma. Ultraviolet (UV) radiation from sunburns causes DNA damage in skin cells, leading to mutations that can result in melanoma. Repeated sunburns exacerbate this risk, making it a critical factor in melanoma development.

A. Atrial depolarization. B. Atrial repolarization. C. Ventricular depolarization. D. Ventricular repolarization.

Correct Answer is D

Explanation

Choice A rationale

Atrial depolarization refers to the electrical activation of the atria, which is depicted by the P wave on an ECG, not the T wave. The P wave represents the contraction phase of the atria as it pumps blood into the ventricles. Therefore, this option is incorrect for the T wave.

Choice B rationale

Atrial repolarization is the process of the atria returning to their resting state. This repolarization is generally obscured by the QRS complex on an ECG and is not associated with the T wave. Thus, this answer choice is also incorrect.

Choice C rationale

Ventricular depolarization is represented by the QRS complex on an ECG. It indicates the ventricles are contracting to pump blood to the lungs and the rest of the body. Therefore, it does not correlate with the T wave.

Choice D rationale

Ventricular repolarization is indicated by the T wave on an ECG. This phase signifies the ventricles returning to their resting state after the contraction. It is the correct answer as it accurately reflects the T wave's function.
