1. What is the most useful patient position for proctologic exams?

A. Trendelenburg
B. Semi-Fowler's
C. Full Fowler's
D. Jack Knife

Correct answer: D

Rationale: The Jack Knife position is the most useful for proctologic exams as it allows the patient to lie face down while keeping the buttocks elevated, providing optimal access for the examination. The Trendelenburg position, characterized by the body being laid flat with the feet higher than the head, is not suitable for proctologic exams. Semi-Fowler's and Full Fowler's positions are typically utilized for respiratory or cardiovascular conditions and are not ideal for proctologic examinations due to their lack of optimal access to the perianal area.

2. Each small square on the EKG paper is:

A. 0.04 seconds long and 5mm tall
B. 0.2 seconds long and 5mm tall
C. 0.04 seconds long and 20mm tall
D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.

3. A healthcare professional is preparing to administer an enteral feeding through a gastrostomy tube. Before administering the feeding, the healthcare professional aspirates some stomach contents and checks the pH. The result is 3.9. What is the next action of the healthcare professional?

A. Administer the feeding as ordered
B. Pull the feeding tube out approximately 3 cm
C. Flush the feeding tube with 60 cc of water
D. Contact the physician

Correct answer: A

Rationale: When the pH of the aspirated stomach contents is 4 or less, it indicates that the gastrostomy tube is in the stomach, confirming correct placement. A pH of 3.9 falls within this range, so the healthcare professional can proceed with administering the enteral feeding. There is no need to adjust the tube placement, flush with water, or contact the physician in this situation as the tube is appropriately positioned for feeding.

4. A nurse caring for a client diagnosed with pertussis is ordered to maintain droplet precautions. Which of the following actions of the nurse upholds droplet precautions?

A. Assign the client to stay in a negative-pressure room
B. Use sterilized equipment when sharing between this client and another person with pertussis
C. Wear a mask if coming within 3 feet of the client
D. Both A and C

Correct answer: C

Rationale: When caring for a client requiring droplet precautions, it is essential for the nurse to wear a mask when within 3 feet of the client. This practice helps prevent the transmission of droplet particles that may be produced when the client coughs or sneezes. Assigning the client to a negative-pressure room is not typically necessary for droplet precautions unless specifically indicated for airborne precautions. Using sterilized equipment when sharing between clients with pertussis is important for infection control but does not directly relate to droplet precautions. Therefore, the correct action to uphold droplet precautions in this scenario is to wear a mask when coming within close proximity to the client.

5. Cheryl M. has a serious swallowing disorder. She has asked you for a glass of water. The doctor has ordered honey thickness liquids for her. Water is not a honey thickness liquid. It is much thinner. What should you do?

A. Tell the resident that she cannot have water.
B. Give her applesauce instead of the water.
C. Tell Cheryl that she is NPO until midnight.
D. Thicken the water and give it to her.

Correct answer: D

Rationale: You can give Cheryl the water that she has requested; however, since water is not a honey-thick liquid as ordered by the doctor, you must thicken it with a commercial thickener before giving it to her. This will ensure that the water is at the appropriate consistency for her swallowing disorder. Choices A, B, and C are incorrect: A) Telling the resident she cannot have water is not the best course of action without attempting to modify it first. B) Giving her applesauce instead of water does not address the specific request for water. C) Placing Cheryl on NPO status until midnight is unnecessary and does not address her immediate request for water.
