A nurse is preparing to administer an enteral feeding to a client who has an NG tube in place.

Which of the following methods should the nurse use to verify the correct placement of the NG tube?

Check the pH of the gastric aspirate.

Observe the color of the gastric aspirate after adding blue dye to the formula.

Auscultate over the epigastrium.

Measure the length of the inserted NG tube.

Answer and Explanation

The Correct Answer is A

A. Correct. Checking the pH of the gastric aspirate is the most reliable method to verify the correct placement of the NG tube. Gastric aspirate typically has an acidic pH (pH < 5), indicating that the tube is in the stomach.
B. Observing the color of the gastric aspirate after adding blue dye to the formula is not a standard or recommended method for verifying NG tube placement.
C. Auscultating over the epigastrium may help to identify the presence of air in the stomach, but it does not confirm that the NG tube is correctly placed in the stomach or the intestines.
D. Measuring the length of the inserted NG tube can help determine the distance from the nose to the stomach, but it does not ensure correct placement in the stomach.

Correct Answer is {"A":{"answers":"A,B"},"B":{"answers":"B"},"C":{"answers":"B"},"D":{"answers":"A"},"E":{"answers":"A"},"F":{"answers":"A,B"}}

Explanation

a. Hemiparesis: Both

Higher fatality rate: Hemorrhagic CVA
Rupture of vessel: Hemorrhagic CVA
Loss of blood flow: Ischemic CVA
Most common: Ischemic CVA
Altered sensorium: Both

Rationale: A cerebrovascular accident (CVA), or stroke, is a sudden interruption of blood supply to the brain, resulting in neurological damage. There are two main types of stroke: ischemic and hemorrhagic. Ischemic stroke occurs when a blood clot or plaque blocks an artery that supplies blood to the brain, causing tissue death due to lack of oxygen and nutrients. Hemorrhagic stroke occurs when a blood vessel in the brain ruptures, causing bleeding into the brain tissue or the surrounding space. Both types of stroke can cause hemiparesis (weakness on one side of the body), altered sensorium (changes in consciousness, alertness, or orientation), and other neurological deficits depending on the location and extent of the damage. However, hemorrhagic stroke has a higher fatality rate than ischemic stroke because of the increased risk of intracranial pressure, cerebral edema, and brain herniation. Ischemic stroke is more common than hemorrhagic stroke, accounting for about 87% of all strokes.

A. Hyperglycemia B. Polydipsia C. Weight gain D. Oliguria

Correct Answer is B

Explanation

A. Hyperglycemia: Hyperglycemia is characteristic of diabetes mellitus, not diabetes insipidus. Diabetes insipidus involves an issue with antidiuretic hormone (ADH) and water balance, not glucose regulation.

B. Polydipsia: This is a hallmark symptom of diabetes insipidus. It refers to excessive thirst due to the body’s inability to retain water, leading to dehydration and compensatory increased fluid intake.

C. Weight gain: Weight gain is not typically associated with diabetes insipidus. The condition usually leads to weight loss due to fluid loss.

D. Oliguria: Oliguria (reduced urine output) is the opposite of what occurs in diabetes insipidus. The condition is characterized by polyuria, or excessive urination, due to the kidneys' inability to concentrate urine.
