Correct Answer: B

Rationale: The correct answer is to irrigate the tube as per physician's order. A client with a nasogastric tube is at risk of the tube kinking or clotting off, which can lead to complications such as abdominal distention or vomiting. To ensure the patency of the tube, the nurse should follow the physician's orders and facility policy to irrigate the tube with water or a solution as needed. Maintaining a constant connection to low-intermittent suction (Choice A) is not typically done to maintain tube patency. Suctioning the mouth and nose every shift (Choice C) is not directly related to maintaining nasogastric tube patency. Performing a daily fecal occult blood sample (Choice D) is unrelated to maintaining the patency of a nasogastric tube.

Correct Answer: C

Rationale: Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys the beta cells in the pancreas, leading to a lack of insulin production. Insulin is essential for regulating blood glucose levels and enabling cells to use glucose for energy. Understanding that type 1 diabetes results from the destruction of beta cells helps patients comprehend the need for insulin replacement therapy. Choices A and B are incorrect as type 1 diabetes is not primarily caused by diet or exercise habits. Choice D is incorrect because type 1 diabetes is not about the body's cells rejecting insulin but rather the lack of insulin production due to beta cell destruction.

Correct Answer: D

Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (Choice B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (Choice C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (Choice A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.

Correct Answer: D

Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues. To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen. Stooped posture (Choice A) is not directly related to an increased respiratory rate. Narcotic analgesics (Choice B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (Choice C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.

Correct Answer: A

Rationale: When caring for a client with swallowing difficulties, it is crucial to prevent aspiration of food into the lungs. Appropriate interventions include auscultating lung sounds every shift and after feedings to assess for any changes in breathing patterns, maintaining suction equipment at the client's bedside in case of difficulties, and providing instruction on swallowing exercises. Keeping the client in an upright position at all times is not necessary and may not always be feasible or comfortable for the client. This rigid requirement is not part of the standard care protocol for managing swallowing difficulties.
