LVN Physiological Integrity Test 3

Question 1

A LVN is assessing a patient's vital signs. Which vital sign provides the most immediate information about the patient's cardiovascular status?

Accepted Answer

Pulse

Answer

The pulse provides the most immediate and direct information about a patient's cardiovascular status because it reflects the heart rate, rhythm, and the strength of the heart's contractions. It directly indicates how effectively the heart is pumping blood throughout the body. While blood pressure is also crucial, the pulse offers a quicker, initial assessment of cardiac function and perfusion.

Question 2

During a routine physical assessment, a LVN notices the patient has clubbing of the fingers. What condition might this indicate?

Accepted Answer

Chronic obstructive pulmonary disease (COPD)

Answer

Clubbing of the fingers, characterized by the enlargement of the fingertips and downward sloping of the nails, is a classic sign of chronic hypoxia. This condition is frequently observed in patients with chronic obstructive pulmonary disease (COPD) due to long-term impaired gas exchange. It indicates prolonged oxygen deprivation to the extremities and warrants further respiratory assessment.

Question 3

When assessing a patient's fluid status, which finding indicates dehydration?

Accepted Answer

Decreased skin turgor

Answer

Decreased skin turgor, where the skin remains tented after being pinched, is a direct and reliable indicator of dehydration. This occurs due to a loss of fluid in the interstitial spaces, reducing the skin's elasticity. The other options, such as pitting edema or jugular venous distention, are signs of fluid overload.

Question 4

A LVN is caring for a patient with a nasogastric tube. What is the correct method to verify the tube's placement?

Accepted Answer

Check the pH of aspirated gastric contents

Answer

The most reliable and commonly used bedside method to verify nasogastric tube placement is to aspirate gastric contents and check their pH. Gastric fluid is typically highly acidic (pH 1-5), which confirms the tube is correctly positioned in the stomach. Auscultating for bowel sounds is not a definitive method for placement verification and can be misleading.

Question 5

A LVN is administering medications to a patient with diabetes mellitus. Which finding requires immediate attention?

Accepted Answer

Shaking hands and sweating

Answer

Shaking hands and sweating are classic and critical signs of hypoglycemia, or low blood glucose, in a patient with diabetes mellitus. Hypoglycemia can rapidly progress to severe neurological impairment, seizures, or loss of consciousness if not treated immediately. Therefore, these symptoms require urgent assessment of blood glucose and prompt intervention to raise blood sugar levels.
