• Avocados, strawberries, and potatoes

A patient with nasogastric suctioning is experiencing diarrhea. The patient is ordered a morning dose of Lasix 20mg IV. Patient's potassium level is 3.0. What is your next nursing intervention?A. Hold the dose of Lasix and notify the doctor for further orders

• Administered the Lasix and notify the doctor for further

orders

• Turn off the nasogastric suctioning and administered a

laxative

normal range

• Hold the dose of Lasix and notify the doctor for further orders

A patient is presenting with an orthostatic blood pressure of 80/40 when she stands up, thready and weak pulse of 58, and shallow respirations. In addition, the patient has been having frequent episodes of vomiting and nausea and is taking hydrochlorothiazide. Which of the following findings would explain the patient's condition?

• Potassium level of 7.0
• Potassium level of 3.5
• Potassium level of 2.4
• None of the options are correct
• Potassium level of 2.4

Which patient is at a potential risk for Digoxin toxicity?

• A patient with Cushing's syndrome taking Laxis 20 mg

IV twice a day

• A patient with a calcium level of 8.9
• A patient with a potassium level of 3.8
• A patient presenting with painful muscle spasms and

positive Trousseau's sign

• A patient with Cushing's syndrome taking Laxis 20 mg IV twice a day

Which of the following is indicative of an EKG change in a case of hypokalemia?

• Widened QRS complex and prolonged PR interval
• Prolonged ST interval and Widened T-wave
• Tall T-waves and depressed ST segment
• ST depression and inverted T-wave
• ST depression and inverted T-wave

A patient has a potassium level of 2.0. What would you expect to be ordered for this patient?

• Potassium 30 meq IV push
• Infusion of Potassium intravenously
• An oral supplement of potassium
• Intramuscular injection of Potassium
• Infusion of Potassium intravenously

When the cell presents with the same concentration on the inside and outside with no shifting of fluids this is called?

• Hypotonic
• Hypertonic
• Isotonic
• Osmosis
• Isotonic

Which of the following is not a hypertonic fluid?

• 3% Saline

B. D5W

• 10% Dextrose in Water (D10W)
• 5% Dextrose in Lactated Ringer's

B. D5W

What type of fluid would a patient with severe hyponatremia most likely be started on?

• Hypotonic
• Hypertonic
• Isotonic
• Colloid
• Hypertonic

When administering a hypertonic solution the nurse should closely watch for?

• Signs of dehydration
• Pulmonary Edema
• Fluid volume deficient
• Increased Lactate level
• Pulmonary Edema

A patient with cerebral edema would most likely be order what type of solution?

• 3% Saline
• 0.9% Normal Saline
• Lactated Ringer's
• 0.225% Normal Saline

A: 3% Saline. A patient with cerebral edema would be ordered a HYPERTONIC

solution to decrease brain swelling. The solution would remove water from the brain cells back into the intravascular system to be excreted. 3% Saline is the only hypertonic option._______ solutions cause cell dehydration and help increase fluid in the extracellular space.

• Hypotonic
• Osmosis
• Isotonic
• Hypertonic
• Hypertonic

D5W solutions are sometimes considered a hypotonic solution as well as an isotonic solution because after the body metabolizes the dextrose the solution acts as a hypotonic solution.True False TRUE. D5W is classified as a ISOTONIC fluid BUT after administration the body metabolizes the dextrose and the fluid left over is a hypotonic solution.

Which solution below is NOT a hypertonic solution?

• 5% Dextrose in 0.9% Saline
• 5% Saline
• 5% Dextrose in Lactated Ringer's
• 0.33% saline (1/3 NS)
• 0.33% saline (1/3 NS)

Which patient below would NOT be a candidate for a hypotonic solution?

• Patient with increased intracranial pressure
• Patient with Diabetic Ketoacidosis
• Patient experiencing Hyperosmolar Hyperglycemia
• All of the options are correct
• Patient with increased intracranial pressure

Which condition below could lead to cell lysis, if not properly monitored?

• Isotonicity
• Hypertonicity
• Hypotonicity
• None of the options are correct
• Hypotonicity

. ________ fluids remove water from the extracellular space into the intracellular space.

• Hypotonic
• Hypertonic
• Isotonic
• Colloids
• Hypotonic

Isotonic fluids cause shifting of water from the extracellular space to the intracellular space.True False FALSE. HYPOTONIC fluids cause shifting of water from the extracellular space to the intracellular space (not isotonic) A patient is being admitted with dehydration due to nausea and vomiting. Which fluid would you expect the patient to be started on?
