HESI 799 RN Exit Exam Capstone

Correct Answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

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: A

Rationale: Injections over 1 mL should be split into two separate injections for young children. This helps in preventing discomfort, ensuring proper absorption, and reducing the risk of tissue damage. Giving the medication in one injection of 2.0 ml might be too much for a 2-year-old child. Choices B and D are incorrect because the dorsal gluteal site is not recommended for children due to potential injury, and changing the form of medication might not be necessary if the volume can be adjusted. Choice C is unnecessary as splitting the dose into two injections is the appropriate action.

Correct Answer: A

Rationale: The correct answer is A. Infections, like a cold and ear infection, increase the body's metabolic needs and insulin resistance, making diabetic ketoacidosis (DKA) more likely. While missing insulin doses or not following dietary restrictions can trigger DKA, an illness is the most common precipitating factor in pediatric Type 1 diabetes. Option B is less likely as missing insulin can lead to hyperglycemia but might not be the immediate cause of ketoacidosis. Option C can contribute to DKA over time, but the acute trigger is usually an illness. Option D, overexertion during exercise, is less likely to cause DKA compared to an infection.

Correct Answer: B

Rationale: An S3 heart sound is often a normal finding in pregnant women due to increased blood volume and cardiac output. The nurse should document the finding as part of the routine assessment unless accompanied by other abnormal symptoms. Performing a 12-lead electrocardiogram (Choice A) is unnecessary for a normal S3 heart sound in pregnancy. Notifying the healthcare provider immediately (Choice C) is premature and may lead to unnecessary interventions. Assessing for signs of heart failure (Choice D) is not indicated as an isolated S3 heart sound is typically benign in pregnancy.
