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 C

Explanation

: Chest tube placement is done to remove air or ﬂuid from the pleural space, which is the area between the lungs and the chest wall. The chest tube drainage system is an important tool to monitor and manage the drainage from the chest tube.

It is essential that the chest tube drainage system is placed below the level of the patient's chest and the site of insertion. This is necessary to create a continuous drainage system by allowing gravity to assist in the ﬂow of air or ﬂuid out of the pleural space. If the chest tube drainage system is placed above the insertion site, the ﬂuid will not drain properly, which can cause the ﬂuid to back up into the patient's chest cavity, leading to complications such as pneumothorax or hemothorax.

Therefore, the appropriate statement regarding a chest tube is that the chest tube drainage system must be placed below the site of insertion.

A. 'It is unnecessary for you to go to the restroom at this time." B. 'I can assist you to the bathroom and back to bed." C. 'I cannot assist you at this time, please wait until I finish what I’m doing”. D. 'You cannot go to the bathroom.'

Correct Answer is B

Explanation

Chest tubes are inserted to drain ﬂuid, blood, or air from the pleural space, which is the space between the lung and the chest wall. It is important to ensure that the chest tube is secured properly and the drainage system is functioning properly before the patient is ambulated. Additionally, the patient may experience discomfort or pain during ambulation, so it is important to assess and manage the patient's pain before and after ambulation.

Option A is not appropriate because it disregards the patient's need to use the restroom and may make the patient feel helpless or dependent.

Option c is not appropriate because it does not address the patient's request for assistance and may make the patient feel neglected or uncared for.

Option d is not appropriate because it is a directive statement that does not take into account the patient's autonomy or individual needs. It is important to involve the patient in the decision-making process and provide appropriate care based on their individual needs and preferences.
