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

Answer and Explanation

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+ -

1. 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: 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.

A. Patient will exchange cigaretes for vaping in 5 days B. Patient will stop smoking cigaretes within 7 days C. Patient will smoke only a few cigaretes each day D. Patient will not smoke cigaretes while wearing oxygen

Correct Answer is D

Explanation

This outcome is the most appropriate because smoking can worsen COPD and lead to further respiratory complications, while oxygen is often used to help patients with COPD breathe more easily. Smoking while wearing oxygen can be very dangerous and increases the risk of fire and explosion. Therefore, the best expected outcome is for the patient to completely avoid smoking while wearing oxygen.

Option a is not a recommended solution since vaping may also worsen COPD symptoms and there is limited evidence of its safety in people with respiratory conditions. Option b is a good outcome, but it may not be achievable in such a short time frame. Option c is not an ideal outcome as even a few cigaretes can cause harm to the respiratory system, exacerbate symptoms, and slow down the healing process.
