1. A postoperative client has been diagnosed with paralytic ileus. When performing auscultation of the client’s abdomen, the nurse expects the bowel sounds to be:
- A. Absent
- B. Hyperactive
- C. Normal
- D. Hypoactive
Correct answer: A
Rationale: In paralytic ileus, bowel sounds are typically absent or significantly reduced due to decreased motility of the intestines. This absence of bowel sounds is a key characteristic used in diagnosing paralytic ileus. Hyperactive bowel sounds are not expected in this condition as there is a lack of normal peristalsis. Normal bowel sounds would not be present in paralytic ileus, and hypoactive bowel sounds, which indicate decreased bowel motility, are more commonly associated with conditions like postoperative ileus or constipation, rather than paralytic ileus.
2. A healthcare professional is admitting a client who has influenza. Which of the following types of transmission precautions should the healthcare professional initiate?
- A. Airborne
- B. Droplet
- C. Contact
- D. Protective environment
Correct answer: B
Rationale: Droplet precautions should be initiated for clients with infections that spread via droplet nuclei larger than 5 microns in diameter, such as influenza, rubella, meningococcal pneumonia, and streptococcal pharyngitis. In the case of influenza, the virus is primarily spread through respiratory droplets produced when an infected person coughs, sneezes, or talks. Airborne precautions are used for pathogens that remain infectious over long distances, typically smaller than 5 microns, like tuberculosis. Contact precautions are for diseases transmitted by direct or indirect contact, and protective environment precautions are for immunocompromised individuals to protect them from environmental pathogens.
3. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?
- A. Blood glucose of 350 mg/dL
- B. Serum bicarbonate of 18 mEq/L
- C. Arterial pH of 7.20
- D. Serum potassium of 5.5 mEq/L
Correct answer: C
Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.
4. A healthcare professional is teaching about home safety with a client. Which of the following instructions should the healthcare professional include?
- A. Unplug electronics by holding the plug
- B. Use electrical tape to secure extension cords next to baseboards on the floor
- C. To use a fire extinguisher, aim at the base of the flames
- D. Install slip-resistant rugs on tile floors
Correct answer: B
Rationale: The correct answer is to use electrical tape to secure extension cords next to baseboards on the floor. This practice helps prevent tripping and electrical hazards by keeping cords out of the way. Option A is incorrect as unplugging electronics should be done by holding the plug, not the cord itself. Option C is incorrect because when using a fire extinguisher, it should be aimed at the base of the flames, not at the top. Option D is not directly related to home safety teaching and may not be necessary for all clients, as it suggests an unnecessary change that may not improve safety.
5. A healthcare professional is assessing a client’s extraocular eye movements. Which of the following should the professional do?
- A. Instruct the client to follow a finger through the six cardinal positions of gaze.
- B. Hold a finger 46 cm (18 in) away from the client’s eyes.
- C. Ask the client to cover their right eye during assessment of the left eye.
- D. Position the client 6.1 m (20 feet) away from the Snellen chart.
Correct answer: A
Rationale: Instructing the client to follow a finger through the six cardinal positions of gaze is the correct action when assessing extraocular eye movements. This technique assesses the movement of the eyes in all directions and helps to test cranial nerves 3, 4, and 6, which control eye movements. Choice B is incorrect as the distance mentioned is not relevant for assessing extraocular eye movements. Choice C is incorrect as both eyes need to be assessed independently. Choice D is incorrect as positioning the client 6.1 m (20 feet) away from the Snellen chart is related to visual acuity testing, not extraocular eye movements.
