1. Which of the following procedures describes an opening between the colon and abdominal wall?
- A. ileostomy
- B. jejunostomy
- C. colostomy
- D. cecostomy
Correct answer: C
Rationale: A colostomy is an opening between the colon and abdominal wall. An ileostomy is an opening between the ileum and abdominal wall, not the colon. Jejunostomy is an opening between the jejunum and abdominal wall, and cecostomy is an opening into the cecum. The term 'colostomy' specifically refers to the surgical procedure where a part of the colon is brought through the abdominal wall to create a stoma, allowing feces to leave the body. Therefore, the correct answer is colostomy as it accurately describes the opening between the colon and the abdominal wall, distinct from the other options.
2. What is the best lab test to diagnose disseminated intravascular coagulation (DIC)?
- A. platelet count
- B. prothrombin time (PT)
- C. partial thromboplastin time (PTT)
- D. D-dimer
Correct answer: D
Rationale: The best lab test to diagnose disseminated intravascular coagulation (DIC) is the D-dimer test. In DIC, numerous small clots form throughout the body and are rapidly broken down. D-dimer measures a specific fibrin split product and is the most specific test for DIC. Platelet count (Choice A) is decreased in DIC due to consumption, but it is not specific for diagnosing DIC. Prothrombin time (PT - Choice B) and partial thromboplastin time (PTT - Choice C) are both elevated in DIC because clotting factors have been used up, but they are not specific for DIC as they can be elevated in other conditions as well.
3. A client with urinary tract calculi needs to avoid which of the following foods?
- A. lettuce
- B. cheese
- C. apples
- D. broccoli
Correct answer: B
Rationale: A client with urinary tract calculi needs to avoid foods high in calcium to prevent the formation of more stones. Cheese is high in calcium, so it should be avoided. Lettuce, apples, and broccoli are not typically associated with high calcium content and are safe options for individuals with urinary tract calculi. Therefore, the correct answer is cheese. Choices A, C, and D are not high in calcium and are safe for consumption by individuals with urinary tract calculi.
4. A nurse assesses an 83-year-old female's venous ulcer for the second time that is located near the right medial malleolus. The wound is exhibiting purulent drainage, and the patient has limited mobility in her home. Which of the following is the best course of action?
- A. Encourage warm water soaks to the right foot.
- B. Notify the case manager of the purulent drainage.
- C. Determine the patient's pulse in the right ankle.
- D. Recommend increased activity to reduce the purulent drainage.
Correct answer: A
Rationale: The correct course of action is to encourage warm water soaks to the right foot. This can help promote wound healing and alleviate discomfort. Before recommending increased activity or notifying additional team members, it is crucial to assess arterial blood flow by determining the patient's pulse in the right ankle. Poor arterial blood flow could worsen the condition, making increased activity inappropriate. While notifying the case manager of purulent drainage is important, addressing the wound care directly should be the primary focus at this stage.
5. Which physiologic mechanism best describes the function of the sodium-potassium pump?
- A. active transport
- B. diffusion
- C. filtration
- D. osmosis
Correct answer: A
Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.
