Patient MK is admited with Atrial Fibrillation an irregular heart rhythm. She is also complaining of muscle cramps to her legs and that she started a new diuretic last week. What lab value are you most likely to find on her Complete Metabolic Panel?
Mg2 – 20 mEq/L
Na+ - 123 mEq/L
Ca2 – 10.0 mg/dl
K+ - - 3.1 mEq/L
The Correct Answer is D
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.

Correct Answer is D
Explanation
Explanation: In clients with COPD, the secretions tend to be thick and sticky, which makes it difficult to cough up and clear the airway. To promote respiratory hygiene in this situation, the nurse should recommend increasing fluid intake. Adequate hydration helps to thin the secretions, making them easier to expectorate. The client should aim to drink at least 8-10 glasses of water or other fluids per day unless there is a medical reason not to do so.
Decreasing fluid intake (option a) would make the secretions even thicker and more difficult to clear. Taking Tylenol for secretions (option b) is not a recommended intervention as Tylenol is not indicated for thinning of secretions. Range-of-motion exercises (option c) are important to prevent complications such as pneumonia, but they are not directly related to promoting respiratory hygiene in this situation.
Correct Answer is D
Explanation
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.
