Fluid and Electrolytes ATI Questions
Question 1 of 5
The nurse preparing a site for the insertion of an IV catheter should treat excess hair at the site by:
Correct Answer: C
Rationale: Hair can be a source of infection and should be removed by clipping. Shaving the area can cause skin abrasions, and depilatories can irritate the skin.
Question 2 of 5
A nurse is taking care of a 65-year-old female patient in a medical-surgical unit who is in renal failure; during the assessment the patient complains of tingling in her lips and fingers. When the nurse takes her blood pressure, she has a spasm in her wrist and hand. The nurse suspects:
Correct Answer: B
Rationale: Tetany is the most characteristic manifestation of hypocalcemia and hypomagnesemia. Sensations of tingling may occur in the tips of the fingers, around the mouth, and less commonly in the feet. Taking a normal blood pressure could illicit a carpal spasm if it creates slight ischemia of the ulnar nerve.
Question 3 of 5
The nurse assessing skin turgor in an elderly patient should remember that:
Correct Answer: C
Rationale: Inelastic skin turgor is a normal part of aging. Dehydration, not overhydration, causes inelastic skin with tenting. Overhydration, not dehydration, causes the skin to appear edematous and spongy. Normal skin turgor is dry and firm.
Question 4 of 5
A female patient is discharged from the hospital after having an episode of heart failure. She's prescribed daily oral doses of digoxin (Lanoxin) and furosemide (Lasix). Two days later, she tells her community health nurse that she feels weak and her heart 'flutters' frequently. What action should the nurse take?
Correct Answer: C
Rationale: Furosemide is a potassium-wasting diuretic. A low potassium level may cause weakness and palpitations. Telling the patient to rest more often won't help the patient if she's hypokalemic. Digoxin isn't causing the patient's symptoms, so she doesn't need to stop taking it. The patient should probably avoid caffeine, but this wouldn't resolve potassium depletion.
Question 5 of 5
A patient's lab results show a slight decrease in potassium. The physician has declined to treat with drug therapy but has suggested increasing the potassium through diet. Which of the following would be a good source of potassium?
Correct Answer: D
Rationale: Bananas are high in potassium. Apples, carrots, and asparagus are not high in potassium.
