A nurse is caring for a client who has an NG tube. The nurse tests the pH of the secretions to determine if the tube is correctly placed. Which of the following readings should the nurse expect?

pH 1-4

pH 5-7

pH 8-10

pH 11-14

Answer and Explanation

The Correct Answer is A

A reason:

A pH reading of 1-4 is expected for gastric contents. This acidic range indicates that the NG tube is correctly placed in the stomach, where gastric secretions have a low pH due to hydrochloric acid.

B reason:

A pH reading of 5-7 is more indicative of respiratory secretions or the contents of the small intestine, not the stomach. This range suggests that the NG tube may be incorrectly placed.

C reason:

A pH reading of 8-10 is too alkaline for gastric contents and indicates incorrect tube placement. This range could suggest the presence of intestinal or respiratory secretions, not gastric.

D reason:

A pH reading of 11-14 is highly alkaline and unlikely to be encountered in clinical practice for this purpose. Such a high pH is not compatible with gastric contents and suggests a significant error or contamination in the test.

Correct Answer is C

Explanation

A reason: Pallor. Pallor refers to an abnormal paleness of the skin, which can be caused by various conditions such as anemia or shock. It is not related to heart rate.

B reason: Bradypnea. Bradypnea refers to an abnormally slow breathing rate. It is unrelated to heart rate and is not the correct term for describing an elevated heart rate.

C reason: Tachycardia. Tachycardia is the medical term for an abnormally fast heart rate, typically defined as a heart rate over 100 beats per minute. A heart rate of 115 falls into this category, making tachycardia the correct term.

D reason: Somnolence. Somnolence refers to a state of drowsiness or sleepiness. It is not related to heart rate and is not the appropriate term for describing an elevated heart rate.

A. If you don't have an infection, your hands won't infect others. B. If you wear gloves, you do not have to wash your hands. C. Use an alcohol rub when your hands are visibly soiled. D. Rub all surfaces of your hands with an alcohol rub for 20 to 30 seconds.

Correct Answer is D

Explanation

A reason:

Saying that if you don't have an infection, your hands won't infect others is incorrect. Hands can carry and transmit pathogens even if the person is not visibly ill.

B reason:

Wearing gloves does not replace the need for hand washing. Hands should be washed before and after wearing gloves to prevent contamination.

C reason:

Using an alcohol rub when hands are visibly soiled is incorrect. When hands are visibly dirty, soap and water should be used to ensure thorough cleaning.

D reason:

Rubbing all surfaces of the hands with an alcohol rub for 20 to 30 seconds is correct. This ensures that the alcohol rub is effective in killing pathogens and maintaining hand hygiene.
