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 B

Explanation

: A client with renal disease may have impaired kidney function, which can aﬀect ﬂuid balance in the body. Giving ﬂuids too quickly or increasing the infusion rate too quickly can lead to ﬂuid overload,

which can exacerbate the client's condition. It is important for the nurse to monitor the amount of ﬂuid the client is receiving to ensure that the infusion rate is appropriate for the client's condition and to prevent ﬂuid overload. Checking the intravenous rate every two days is not sufficient; the nurse should monitor the rate regularly and adjust it as necessary based on the client's response.

A. Stop the transfusion. B. Notify the health care provider of the client s response. C. Check the client s vital signs. D. Document the findings.

Correct Answer is A

Explanation

Difficulty breathing is a sign of a potential transfusion reaction. When a client reports difficulty breathing during a blood transfusion, the nurse should stop the transfusion immediately to prevent the reaction from worsening. Once the transfusion is stopped, the nurse can then assess the client's vital signs and notify the healthcare provider of the client's response. Documentation of the findings should also be completed after the client's condition has stabilized. However, stopping the transfusion takes priority over documenting the findings.
