-Guarantee passing score -21 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: The nurse is educating a patient regarding the normal levels of potassium within the blood. Which response by the patient indicates correct understanding of the information presented?

Answer:

"The normal range for potassium is 3.5-5 mEq/L." Question 2: Which component is necessary for active transport of electrolytes to occur?

Answer:

Adenosine triphosphate

Question 3: Which statements regarding the sodium-potassium pump are true?

Answer:

• The pump moves sodium out of the cells and potassium into the cells.
• This pump is an example of active transport.
• The pump moves three sodium ions for every two potassium ions.

Question 4: The student nurse is preparing a presentation regarding the sodium-potassium pump. Which statement should the student include in the presentation?

Answer:

"ATP is required for the sodium-potassium pump to move sodium and potassium ions." "This pump moves sodium out of the cell and potassium into the cell." "This pump moves three sodium ions for every two potassium ions." Question 5: Which is the reason for the movement of electrolytes from one compartment to another compartment in the body?

Answer:

To preserve electrolyte distribution Question 6: A patient has developed a clot in a coronary artery and the heart muscle cells did not make enough ATP. When a nursing student asks, what should the nurse explain about the effect of a poor ATP supply on electrolyte movement?

Answer:

Active transport will be impaired, so the sodium-potassium pumps will not work normally.Question 7: The nurse is providing education to a patient who is diagnosed with osteoporosis who asks, "Is there anything I can take over-the-counter to treat this condition?" Which supplements should the nurse include in the response?

Answer:

Calcium Magnesium Question 8: The nurse is providing care to a patient with decreased levels of serum potassium caused by excessive hormone action that shifts potassium into cells. Which hormone should the nurse expect to be elevated in the laboratory report?

Answer:

Insulin Question 9: Which elements should the nurse include when providing patient teaching regarding the primary functions of electrolytes within the body?

Answer:

Transmitting nerve impulses Regulating acid-base balance Altering the action potential of nerve fibers Maintaining fluid osmolality

Question 10: A patient diagnosed with high blood pressure asks, "Why do I have to monitor my salt intake?" Which explanation should the nurse include in the response to this patient?

Answer:

"Sodium helps to maintain blood pressure. Since your blood pressure is high, you should decrease your sodium intake."

Question 11: Match the electrolyte with its primary function.

Provides the normal electrical activity of the heart Provides the building blocks for bones and teeth Influences function of neuromuscular junctions Incorporates into an energy source for cellular metab

Answer:

Potassium (K+) Calcium (Ca2+) Magnesium (Mg2+) Phosphate (PO4 3-) Question 12: Which serum electrolyte value in a patient should the nurse interpret as within normal limits?

Answer:

Potassium: 4 mEq/L

Question 13: The nurse is monitoring serum electrolyte levels for a patient who was admitted to the emergency department with dehydration. Which data should the nurse report to the primary care provider as abnormal?

Answer:

Serum Na+ of 150 mEq/L Serum K+ of 5.2 mEq/L Serum PO4 3- 2.9 mEq/L Question 14: Which electrolyte may require the use of insulin for regulation and homeostasis?

Answer:

Potassium Question 15: Which statement regarding electrolyte movement from one compartment to another should the nursing student include in a class presentation?

Answer:

"The movement of electrolytes is necessary to preserve their distribution."

Question 16: Match the electrolyte with the correct normal range.

135-145 mEq/L 8.5-10.5 mg/dL or 4-5 mEq/L 1.3-2.1 mEq/L 1.7-2.6 mEq/L

Answer:

Sodium (Na+) Calcium (Ca2+) Magnesium (Mg2+) Phosphate (PO4 3 ?) Question 17: Which electrolyte is the principal cation in the intracellular fluid (ICF) compartment?

Answer:

Potassium Question 18: The nursing student is presenting information related to the movement of electrolytes to fellow classmates. Which process should the nursing student state as moving electrolytes within a body compartment by random movements?

Answer:

Diffusion Question 19: Which body substance is most commonly used to measure the concentration of electrolytes in milliequivalents per liter (mEq/L)?

Answer:

Blood plasma Question 20: Which electrolyte supplement is most important for the nurse to include in the teaching session for a patient who is recovering from a broken bone?

Answer:

Calcium

Question 21: Which statement is true about the regulation of electrolytes?

Answer:

Calcium is regulated by the parathyroid hormone.
