A nurse is assessing the breath sounds of a newborn. Which sound is an expected finding for this developmental level?
Bruits
Crackles
Wheezing
Stridor
The Correct Answer is D
Stridor is a high-pitched, inspiratory sound that indicates partial obstruction of the upper airway. It is a common finding in newborns and can occur due to the presence of mucus, fluid, or a small airway that has not yet fully developed. It is important to note that while stridor is an expected finding in newborns, it should still be assessed and monitored closely by healthcare professionals.
Bruits are abnormal sounds heard over blood vessels and are not related to breath sounds. Crackles are a series of brief, discontinuous, nonmusical sounds heard during inspiration or expiration, indicating fluid in the lungs. Wheezing is a high-pitched, musical sound heard during expiration and can indicate the narrowing of the airways. These sounds are not typically expected in the breath sounds of a newborn.

Correct Answer is B
Explanation
Crackles, also known as rales, are discontinuous sounds that are typically heard during inspiration in patients with heart failure. These sounds are produced by the sudden opening of small airways and alveoli that are filled with fluid or collapsed due to pulmonary congestion. The sound can be described as similar to the sound of rubbing hair between fingers or the sound of Velcro being pulled apart.
Rhonchi are continuous, low-pitched sounds that are typically heard during expiration and are caused by the movement of air through narrowed airways, such as in patients with chronic obstructive pulmonary disease (COPD). Stridor is a high-pitched, continuous sound that is typically heard during inspiration and indicates upper airway obstruction, which can be life-threatening. Neither rhonchi nor stridor are typically heard in patients with heart failure.
Therefore, based on the patient's history and symptoms, the most likely type of breathing sound to be heard on auscultation is crackles/rales.
Correct Answer is D
Explanation
Atrial fibrillation is a common arrhythmia, and diuretics are often used in the management of patients with this condition to help control fluid balance. However, diuretics can cause electrolyte imbalances, especially hypokalaemia (low potassium levels), which can lead to muscle cramps and other complications.
A Complete Metabolic Panel (CMP) is a blood test that measures various electrolytes, glucose, and other important components. Among the options given, the most likely lab value to be abnormal in Patient MK's case is a low level of potassium (K+), which is consistent with her symptoms and diuretic use. Option d, K+ -

- mEq/L, is the correct option as it represents a low level of potassium, which is defined as a value less than 3.5 mEq/L.
Option a, Mg2 – 20 mEq/L, represents high magnesium levels, which are not typically associated with diuretic use or muscle cramps. Option b, Na+ - 123 mEq/L, represents low sodium levels, which are less likely to occur with diuretic use, and are typically associated with other conditions. Option c, Ca2 – 10.0 mg/dl, represents normal calcium levels and is not typically affected by diuretic use.
