HESI Nutrition Exam

Correct Answer: A

Rationale: To prevent unnecessary hypoxia during suctioning of a tracheostomy, the nurse must apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia by removing too much oxygen from the patient. Maintaining a sterile technique (choice B) is important to prevent infection but does not directly relate to preventing hypoxia. Lubricating the catheter tip (choice C) helps with the insertion process but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not contribute to preventing hypoxia.

Correct Answer: D

Rationale: Assisting with oral hygiene is the essential initial step before collecting a sputum specimen for acid-fast bacillus (AFB) to prevent contamination of the sample. Ensuring the client's mouth is clean reduces the risk of introducing unwanted bacteria into the specimen. Asking the client to cough sputum into a container, having the client take deep breaths, and providing a specimen container are important steps in the specimen collection process, but they should follow ensuring proper oral hygiene.

Correct Answer: C

Rationale: When caring for a client with a new tracheostomy, the priority assessment is checking the tracheostomy site for signs of infection. This is essential to detect early signs of complications such as infection, which can lead to serious issues. Monitoring oxygen saturation is important but not as critical as ensuring the tracheostomy site is free from infection. Pain assessment and level of consciousness are also important but secondary to assessing for signs of infection in this scenario.

Correct Answer: C

Rationale: Black, tarry stools can indicate gastrointestinal bleeding, which is a serious complication of peptic ulcer disease. This finding suggests active bleeding in the gastrointestinal tract, requiring immediate attention. A normal heart rate of 72 beats per minute (choice A) is within the expected range. A hemoglobin level of 12 g/dL (choice B) is also within normal limits. Nausea and vomiting (choice D) are common symptoms associated with peptic ulcer disease but may not necessarily indicate active bleeding like black, tarry stools.

Correct Answer: A

Rationale: The most important instruction for a 65-year-old female client diagnosed with osteoporosis regarding exercise is to engage in weight-bearing activities. Weight-bearing exercises are crucial in maintaining bone density and preventing osteoporosis-related fractures. Choice B is incorrect because the primary focus should be on bone health rather than weight reduction. Choice C is incorrect as avoiding all exercise activities that increase the risk of fracture would limit physical activity, which is essential for overall health. Choice D is incorrect as while strengthening muscles is beneficial, weight-bearing activities directly impact bone health in osteoporosis.
