1. Which of the following is a disadvantage of using a dry heat application?

A. Dry heat is more likely to cause burns than moist heat
B. Dry heat does not penetrate deeply into the tissues
C. Dry heat causes the skin to dry out more quickly
D. Dry heat can quickly cause skin breakdown

Correct answer: C

Rationale: The correct answer is that dry heat causes the skin to dry out more quickly. When comparing dry and moist heat applications, dry heat is less likely to cause burns and skin breakdown. However, one of the disadvantages of dry heat is that it does not penetrate deeply into the tissues and may lead to faster drying out of the skin. This can have negative effects on skin integrity and overall comfort during therapy. Choice A is incorrect because dry heat is less likely to cause burns than moist heat. Choice B is incorrect as dry heat may not penetrate deeply into tissues. Choice D is incorrect as dry heat is less likely to cause skin breakdown compared to moist heat.

2. A patient who is displaying the defense mechanism of Compensation would:

A. Refuse to hear unwanted information.
B. Transfer feelings of negativity to someone else.
C. Overemphasize behaviors which accommodate for perceived weaknesses.
D. Place blame on others for personal actions or mistakes.

Correct answer: C

Rationale: The correct answer is 'Overemphasize behaviors which accommodate for perceived weaknesses.' Compensation involves overemphasizing or exaggerating a particular behavior or trait to make up for or cover up perceived weaknesses in oneself. This defense mechanism allows individuals to focus on their strengths rather than acknowledging their shortcomings. Choices A, B, and D are incorrect. Refusing to hear unwanted information relates more to denial, transferring feelings of negativity to someone else is projection, and placing blame on others is an example of the defense mechanism known as externalization.

3. When placing a patient in the AP position for an X-ray, what position would the patient be in?

A. Facing the X-ray film.
B. Right side against the X-ray film.
C. Left side against the X-ray film.
D. Facing away from the X-ray film

Correct answer: D

Rationale: The AP position stands for Anteroposterior Projection. When a patient is in the AP position for an X-ray, they are facing away from the X-ray film. This positioning allows for a clear view of the structures being imaged from front to back. Choices A, B, and C are incorrect because the patient is not facing or positioned against the X-ray film in the AP position, but rather facing away from it to capture the necessary diagnostic information.

4. When providing mouth care to a patient in a coma, what should you do to provide good and safe mouth care?

A. keep the head of the bed up to prevent aspiration
B. brush the teeth and rinse the mouth with a cup of water
C. use a special foam swab to brush only the tongue
D. use a special foam swab to brush the tongue and teeth

Correct answer: D

Rationale: When providing mouth care to a patient in a coma, it is crucial to use a special foam swab to brush the tongue and teeth. This method helps maintain good oral hygiene for comatose patients. Special foam swabs are designed to effectively clean all areas of the mouth, including the cheeks and tongue, ensuring thorough care. Using water for mouth care in comatose patients can lead to aspiration, so it is important to avoid this practice. Keeping the head of the bed up alone does not prevent aspiration during mouth care for comatose patients, making choice A incorrect. Merely brushing the tongue (choice C) or using a foam swab only on the tongue (choice B) may not provide the comprehensive mouth care necessary for patients in a coma.

5. A client is preparing to administer an enema to a 64-year-old client. Which of the following actions of the nurse is most appropriate?

A. Assist the client to lie in the semi-Fowler position
B. Apply lubricating jelly to the tip of the catheter before insertion
C. Instill a total of 30cc of fluid into the client's rectum
D. Ask the client to hold the solution in for 30 seconds

Correct answer: B

Rationale: When administering an enema to a client, the nurse should place the client in the Sims' position for easy access. The correct action is to apply lubricating jelly to the tip of the catheter before insertion to facilitate a smoother procedure. It is essential to instill a maximum of 750 to 1000 cc of fluid for an adult client, not just 30cc. Following administration, the nurse should ask the client to hold the solution for at least 5 minutes to allow for the desired effect of the enema. Therefore, choice B is the most appropriate action, as choices A, C, and D are incorrect due to inaccuracies in positioning, enema volume, and retention time.
