1. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?
- A. pancreatic amylases, small intestine
- B. brush border enzymes, small intestine
- C. luminal enzymes, large intestine
- D. pancreatic amylases, pancreas
Correct answer: A
Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.
2. A client had a total hip arthroplasty. Which of the following prescriptions should the nurse verify with the provider?
- A. Administer enoxaparin 30 mg subcutaneously every 12 hr
- B. Place a wedge or pillow between the client's legs when turning.
- C. Instruct the client to restrict flexion of the hip past 120°.
- D. Encourage the client to perform foot and calf exercises every 2 hr
Correct answer: Instruct the client to restrict flexion of the hip past 120°.
Rationale: Following a total hip arthroplasty, the client should be instructed to restrict hip flexion past 90 degrees to prevent dislocation of the prosthesis. Restricting flexion past 120 degrees is excessive and could lead to complications. Therefore, the nurse should verify this prescription with the provider to ensure the client's safety and proper postoperative care.
3. A nurse is teaching a group of newly licensed nurses about measures to take when caring for a client who is on contact precautions. Which of the following should the nurse include in the teaching?
- A. Remove the protective gown after leaving the client's room
- B. Place the client in a room with positive pressure
- C. Wear gloves when providing care to the client
- D. Wear a mask when entering the client's room
Correct answer: C
Rationale: The correct measure to include when caring for a client on contact precautions is to wear gloves when providing care. Gloves help prevent the spread of infection and cross-contamination. Choice A is incorrect because the protective gown should be removed before leaving the client's room to prevent the spread of pathogens. Choice B is incorrect as clients on contact precautions should be in a room with negative pressure to prevent the spread of airborne contaminants. Choice D is incorrect as wearing a mask when changing linens is not specifically required for contact precautions.
4. The healthcare provider is assessing an immobile patient for deep vein thrombosis (DVT). What should the healthcare provider do?
- A. Lightly rub the lower leg to check for redness and tenderness.
- B. Apply elastic stockings every 4 hours.
- C. Measure the calf circumference of both legs.
- D. Flex the foot while assessing for patient discomfort.
Correct answer: C
Rationale: Measuring the calf circumference of both legs is crucial when assessing for DVT in an immobile patient. A significant increase in the circumference of one calf compared to the other suggests the presence of a deep vein thrombosis. Option A is incorrect because rubbing the lower leg may dislodge a clot if present. Option B is incorrect as elastic stockings should not be removed frequently as this can increase the risk of clot formation. Option D is incorrect as dorsiflexing the foot can lead to pain and should not be done to assess for DVT.
5. The nurse supervises care of a client who is receiving enteral feeding via a nasogastric tube. The nurse determines that care is appropriate if which of the following is observed? (Select all that apply)
- A. The nursing assistant aspirates and measures the amount of the gastric aspirate
- B. The nursing assistant elevates the head of the client’s bed 30 degrees
- C. The nursing assistant warms the formula to room temperature
- D. B, C
Correct answer: D
Rationale: Elevating the head of the bed to 30 degrees reduces the risk of aspiration by promoting proper digestion and preventing reflux. Warming the formula to room temperature is essential to prevent discomfort and complications. Aspirating and measuring the gastric aspirate is not a recommended nursing action for monitoring enteral feeding via a nasogastric tube, as it can introduce the risk of introducing contaminants into the feeding tube. Therefore, choices A and B are incorrect, making choice D the correct answer.
