Fluid and Electrolytes ATI Questions

Question 1 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 2 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 3 of 5

Which of the following might the nurse assess in a patient diagnosed with hypermagnesemia?

Correct Answer: A

Rationale: To gauge a patient's magnesium status, the nurse should check deep tendon reflexes. If the reflex is absent, this may indicate high serum magnesium.

Question 4 of 5

A patient is receiving furosemide (Lasix) 40 mg/d IV. What electrolyte value should be monitored when a patient is receiving a loop diuretic?

Correct Answer: C

Rationale: The diuretics act on the ascending loop of Henle to prevent re-absorption of water, potassium, and sodium. Because of this, potassium and sodium levels should be monitored when a patient is receiving diuretics.

Question 5 of 5

A patient is taking spironolactone (Aldactone) to control her hypertension. Her serum potassium level is 6 mEq/L. For this patient, the nurse's priority would be to assess her:

Correct Answer: D

Rationale: Although changes in all these findings are seen in hyperkalemia, ECG changes can indicate potentially lethal arrhythmias such as ventricular fibrillation. It wouldn't be appropriate to assess the patient's neuromuscular function, bowel sounds, or respiratory rate for effects of hyperkalemia.
