Your patient has a CMP drawn to determine their electrolytes. Only part of the values have resulted including the Na+ which is 121 mEq/l. What type of electrolyte imbalance is the patient having?
Hypocalcemia
Hyperkalemia
Hypernatremia
Hyponatremia
The Correct Answer is D
Explanation: The normal range of sodium (Na+) in the blood is 135-145 mEq/L. The patient's sodium level of 121 mEq/L is below the normal range, indicating a low sodium level, which is called hyponatremia.
Hyponatremia is a common electrolyte imbalance that can be caused by a variety of factors, including excessive sweating, vomiting, diarrhea, certain medications, kidney disease, and hormonal imbalances. It can cause symptoms such as nausea, headache, confusion, seizures, and coma, and it can be a medical emergency if the sodium level drops rapidly or severely.

Correct Answer is B
Explanation
Hemoglobin is a protein found in red blood cells that plays a crucial role in transporting oxygen from the lungs to the body's tissues and organs. When oxygen is breathed in, it binds to the hemoglobin in red blood cells, forming oxyhemoglobin. This oxyhemoglobin is then transported throughout the body via the circulatory system, delivering oxygen to the cells that need it

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.
