KO is admitted with severe dehydration and electrolyte unbalances. What assessment findings are you most likely to ﬁnd initially before ﬂuid balance reaches homeostasis?

Crackles to Bilateral lobes

Tenting skin and wet mucous membranes

C Tachycardia and hypotension

+4 edema to bilateral lower extremities and confusion

Answer and Explanation

The Correct Answer is C

Dehydration can cause a decrease in blood volume, leading to a drop in blood pressure (hypotension) and an increase in heart rate (tachycardia) as the body tries to compensate. Tenting skin and dry mucous membranes are also signs of dehydration, but wet mucous membranes are not. Crackles in the lungs, edema, and confusion can occur with ﬂuid overload, but not with dehydration.

Correct Answer is A

Explanation

Before pumping the medication into the chamber, you should educate the patient to exhale. This means that the patient should breathe out fully before using the inhaler. This helps to empty the lungs of air and create more space for the medication to be inhaled.

A. Mg2 – 20 mEq/L B. Na+ - 123 mEq/L C. Ca2 – 10.0 mg/dl D. K+ - - 3.1 mEq/L

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+ -

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.

Respiratory Therapy has an order to perform chest physiotherapy on your patient who has COPD. Your patient’s lung sounds are diminished, but free of secretions. What should the proper response be from the nurse to the respiratory therapist:

The nurse is caring for a client who recently had surgery on her left hip. What should be the priority teaching for the patient after surgery to prevent complications?

A patient presents to the Emergency Room with swollen legs and shortness of breath. He tells you that he has a history of heart failure which causes the ﬂuid to build up m his legs and lungs. When you listen to his lung sounds you are most likely to hear which type of breathing sounds?

The nurse is obtaining a pulse oximetry reading for a client admited with exacerbation of chronic obstructive pulmonary disease (COPD). When observing a reading of 91%. what action should the nurse perform?

Coughing and Deep breathing is taught to a patient to prevent recurrent pneumonia. She is educated to breathe in deeply first to over expand lung volume: this is called what?

KO is admitted with severe dehydration and electrolyte unbalances. What assessment findings are you most likely to ﬁnd initially before ﬂuid balance reaches homeostasis?

The nurse provides care for the client with an asthma crisis experiencing hypoxia. Which lung sound would the nurse expect to auscultate on the physical assessment?

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?
