Which technique is most reliable to confirm correct placement of a nasogastric tube prior to initiating tube feedings?
Fluoroscopy to identify location.
Aspirate contents and measure the pH.
Inject air and listen for gurgling sounds.
Observe for bubbles after placing the end of the tube in a cup of water.
The Correct Answer is B
This is because the pH of gastric contents is acidic (less than 5.5) and can indicate that the tube is in the stomach. This method is predictive of the correct placement of a nasogastric tube.
Choice A is wrong because fluoroscopy is not the most reliable method to confirm the correct placement of a nasogastric tube. It is an imaging technique that uses X-rays to show the movement of the tube, but it is not always available or feasible.
Choice C is wrong because injecting air and listening for gurgling sounds is not a reliable method to confirm the correct placement of a nasogastric tube. It can cause false-positive results and does not differentiate between the stomach and the respiratory tract.
Choice D is wrong because observing for bubbles after placing the end of the tube in a cup of water is not a reliable method to confirm the correct placement of a nasogastric tube. It can also cause false-positive results and does not differentiate between the stomach and the respiratory tract.

Correct Answer is A
Explanation
“It wouldn’t have mattered what you had worn.” This response by a nurse is appropriate because it validates the client’s feelings and helps to reduce self-blame. It also conveys that rape is not caused by the victim’s clothing or behavior, but by the perpetrator’s violence and lack of respect.
Choice B. “The current styles are an invitation to disaster.” is wrong because it implies that the client is responsible for the rape and that she could have prevented it by dressing differently. This response is judgmental and insensitive, and may increase the client’s guilt and shame.
Choice C. “Never mind about blame.
That will be determined by the court.” is wrong because it dismisses the client’s feelings and does not address her emotional needs.
It also suggests that the nurse does not believe the client or support her. This response may make the client feel isolated and distrustful.
Choice D. “Some people don’t have very good self-control.
We have to help them all we can.” is wrong because it excuses the perpetrator’s behavior and shifts the blame to the victim.
It also implies that rape is a result of sexual desire, rather than an act of violence and domination. This response may make the client feel powerless and helpless.
Correct Answer is C
Explanation
The directive takes effect only if the client is incapable of personally making health care decisions. This statement demonstrates an understanding of health care proxy and care because it reflects the definition of a health care proxy as a person who can make health care decisions for the client only when the client is unable to communicate these themselves.
Choice A is wrong because the daughter does not have the authority to make all of the client’s health care decisions, only those that the client has not specified in advance or that are not covered by the living will.
Choice B is wrong because no extraordinary means, such as cardiopulmonary resuscitation, will be initiated only if the client has expressed this preference in a living will or a do-not-resuscitate order.
Choice D is wrong because the closest relative, such as the spouse, does not have to be consulted before the daughter in making health care decisions, unless the client has designated them as an alternate proxy.
