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 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

When selecting a site on the hand or arm for insertion of an IV catheter, the nurse should:

Correct Answer: B

Rationale: When selecting a site for insertion of an IV catheter, the nurse should choose a distal site, not a proximal site. Selection of a distal site leaves the upper veins available for subsequent cannulations. Instruct the patient to hold his arm in a dependent position to increase blood flow. Never leave a tourniquet in place longer than 2 minutes.

Question 4 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.

Question 5 of 5

A nurse admitting a patient with a history of emphysema reviews her past lab reports and notes that the patient's PaCO2 has been 56 to 64 mmHg. The nurse will be cautious administering oxygen because:

Correct Answer: D

Rationale: When PaCO2 chronically exceeds 50 mm Hg, it creates insensitivity to CO2 in the respiratory medulla, and the use of oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.
