RN HESI Exit Exam Capstone

Correct Answer: B

Rationale: Deep, rapid respirations (Kussmaul respirations) and lethargy are signs of diabetic ketoacidosis (DKA), which occurs in uncontrolled type 1 diabetes. Checking the blood glucose is the priority to confirm hyperglycemia and guide immediate treatment. Pulse oximetry is not the priority in this situation as the issue is related to altered glucose levels, not oxygenation. Arterial blood gases and serum electrolytes may be important later in the management of DKA but are not the initial priority compared to confirming and addressing the hyperglycemia.

Correct Answer: B

Rationale: The correct answer is B. An oxygen saturation of 89% indicates hypoxemia, which is below the normal range (usually 95-100%). This finding requires immediate intervention as it signifies inadequate oxygenation. Options A, C, and D are within normal limits and do not indicate an urgent need for intervention. Option A indicates a good oxygen saturation level, option C denotes a normal respiratory rate, and option D suggests a normal heart rate. Therefore, these options do not require immediate intervention compared to the critically low oxygen saturation level of 89% in option B.

Correct Answer: B

Rationale: Antibiotic ointment is ineffective against athlete's foot, which is a fungal infection. The nurse should instruct the mother to stop using the ointment and ensure the feet are dried properly, as moisture exacerbates fungal infections. Applying a different antifungal medication is a valid option, but addressing the moisture issue by drying the feet completely is the immediate priority. Continuing to use the antibiotic ointment or reapplying it for a longer period will not treat the fungal infection effectively.

Correct Answer: B

Rationale: The correct answer is B. Altered consciousness within the first 24 hours after a temporal injury is a classic sign of epidural hematoma, which is a neurosurgical emergency. This finding occurs due to the rapid expansion of the hematoma, causing compression of the brain. Nausea and vomiting (choice A) are more commonly associated with other types of head injuries, such as concussion. Severe headache and blurred vision (choice C) are symptoms seen in various head injuries but are not specific to epidural hematomas. Loss of motor function on the affected side (choice D) is more indicative of a different type of head injury, such as a contusion or intracerebral hematoma.

Correct Answer: B

Rationale: The correct answer is B: 'I should use my rescue inhaler when I start to experience wheezing.' A rescue inhaler is used during the onset of asthma symptoms, such as wheezing, to quickly open the airways. It is not intended for routine daily use or prevention, which is the role of a maintenance inhaler. Option A is incorrect because a rescue inhaler is not used for prevention but for immediate relief during an asthma attack. Option C is incorrect because the peak flow meter reading is used to monitor asthma control, not to determine when to use a rescue inhaler. Option D is incorrect because using a rescue inhaler only before going to bed does not address the need for immediate relief when wheezing or experiencing asthma symptoms.
