Correct Answer: D

Rationale: The first priority in an acute asthma exacerbation is to administer oxygen to improve the client's oxygen saturation. In this scenario, the client has a low oxygen saturation level of 86%, indicating hypoxemia, which can be life-threatening. Administering oxygen therapy will help improve oxygenation and support vital organ function. Once the oxygen levels are stabilized, further interventions such as bronchodilators can be implemented. Placing the client in a high-Fowler's position may also be beneficial, but ensuring adequate oxygenation takes precedence in this critical situation. Obtaining a peak flow reading is important for asthma management but is not the first intervention needed in a client with severe hypoxemia.

Correct Answer: B

Rationale: A weak pulse and numbness distal to a radial artery catheter may indicate occlusion or damage to the artery, and immediate removal of the catheter is necessary to prevent complications. Therefore, promptly removing the catheter from the radial artery (Choice B) is the correct action. Monitoring the site (Choice A) would delay necessary intervention, elevating the client's arm (Choice C) may not address the underlying issue, and notifying the healthcare provider for surgery (Choice D) without removing the catheter promptly could lead to further complications.

Correct Answer: B

Rationale: The correct action for the nurse to take first when a client with Alzheimer's disease is becoming increasingly confused is to monitor the client's vital signs (Choice B). Increased confusion in Alzheimer's disease patients may indicate underlying issues like infection, dehydration, or medication side effects. Monitoring vital signs is crucial in identifying any potential causes of the confusion. Choices A, C, and D are not the priority in this situation. Reorienting the client to time and place (Choice A) can be helpful but is not the first priority. Providing calming activities (Choice C) and consulting with the healthcare provider about medication adjustments (Choice D) may be necessary but should come after assessing the client's vital signs to rule out immediate physical causes of confusion.

Correct Answer: C

Rationale: A blood glucose level of 55 mg/dL indicates hypoglycemia, which should be treated with a fast-acting carbohydrate to quickly raise the blood sugar. Administering 15 grams of a fast-acting carbohydrate, such as glucose tablets or juice, is the appropriate initial intervention for hypoglycemia. Giving a glucagon injection is reserved for severe cases or when the client is unconscious. Encouraging the client to eat a high-protein snack is not appropriate for treating acute hypoglycemia, as it is a slower-acting form of glucose. Rechecking the blood glucose level is important but should occur after providing immediate treatment to raise the blood sugar level.

Correct Answer: D

Rationale: The correct answer is D: "I need to get the client's written consent before I release any information to you." In this scenario, the nurse must obtain the client's written consent before disclosing any information to the social worker. This process ensures compliance with privacy laws like HIPAA, which are designed to protect client confidentiality. Choice A is incorrect because it does not address the need for consent. Choice B is incorrect as it is unprofessional and does not focus on obtaining consent. Choice C is incorrect as it suggests information can be shared without consent, which goes against privacy laws.
