HESI CAT Exam 2022

HESI LPN

1. Parents who have one male child with sickle cell anemia are concerned about having more children with the disease. What client teaching should the nurse provide?

A. All future children will be carriers, but will not necessarily have the disease
B. There is a chance that each future child will have the disease
C. Only male children cannot inherit the sickle cell disease trait
D. Only one out of four of their children will definitely manifest the disease

Correct answer: B

Rationale: The correct answer is B. Each child has a 25% chance of having sickle cell anemia if both parents are carriers of the trait. Choice A is incorrect because not all future children will be carriers; some may have the disease. Choice C is incorrect as both male and female children can inherit the sickle cell disease trait. Choice D is incorrect as the chance is not fixed at one out of four; each child has an independent 25% chance of having the disease.

2. In a client in her third trimester of pregnancy, an S3 heart sound is auscultated. What intervention should the nurse take?

A. Notify the healthcare provider
B. Limit the client’s fluids
C. Prepare the client for an echocardiogram
D. Document in the client’s record

Correct answer: D

Rationale: An S3 heart sound can be a normal finding in pregnancy due to increased blood volume and flow. In this scenario, there is no immediate need for further interventions. Documenting this finding in the client's record is essential for tracking the client's health status and ensuring proper follow-up if needed. Notifying the healthcare provider, limiting fluids, or preparing for an echocardiogram is unnecessary as it is likely a physiological finding in pregnancy. These interventions should only be considered if other symptoms suggestive of a cardiac issue are present.

3. After 2 days of treatment for dehydration, a child continues to vomit and have diarrhea. Normal saline is infusing, and the child’s urine output is 50ml/hour. During morning assessment, the nurse determines that the child is lethargic and difficult to arouse. Which action should the nurse implement?

A. Perform a finger stick glucose test
B. Increase the IV fluid flow rate
C. Review 24-hour intake and output
D. Obtain arterial blood gases

Correct answer: A

Rationale: Lethargy and difficulty arousing may indicate hypoglycemia, which should be assessed before other actions. Performing a finger stick glucose test is crucial to evaluate the child's blood sugar levels and address hypoglycemia promptly. Increasing the IV fluid flow rate is not indicated without knowing the glucose status. Reviewing 24-hour intake and output is important but not the priority when lethargy and difficulty arousing are present. Obtaining arterial blood gases is not the primary assessment needed in this situation.

4. The nursing staff on a medical unit includes a registered nurse (RN), practical nurse (PN), and an unlicensed assistive personnel (UAP). Which task should the charge nurse assign to the RN?

A. Transport a client who is receiving IV fluid to the radiology department
B. Administer PRN oral analgesics to a client with a history of chronic pain
C. Supervise a newly hired graduate nurse during an admission assessment
D. Complete ongoing focused assessments of a client with wrist restraints

Correct answer: C

Rationale: The correct answer is C because supervising a newly hired graduate nurse during an admission assessment is a task that falls within the registered nurse's scope of practice. Registered nurses are responsible for overseeing and delegating tasks, especially to new staff, to ensure proper assessment and care delivery. Choices A, B, and D involve tasks that can be appropriately assigned to practical nurses or unlicensed assistive personnel as they are within their scope of practice. Transporting a client, administering oral analgesics, and completing focused assessments do not require the advanced knowledge and skills of a registered nurse.

5. The client with diabetes mellitus type 1 has a fruity breath odor. What is the priority nursing action?

A. Evaluate the client’s intake and output
B. Measure the client’s capillary blood glucose
C. Consult with the dietitian about the client’s diet
D. Apply a pulse oximeter to the client’s finger

Correct answer: B

Rationale: Fruity breath odor in a client with diabetes mellitus type 1 can indicate ketoacidosis, a serious complication. Measuring the client’s capillary blood glucose is the priority nursing action in this scenario as it helps diagnose and manage the condition effectively. Evaluating intake and output may be important for overall assessment but not the priority when dealing with a potential emergency like ketoacidosis. Consulting with a dietitian about the client’s diet is important for long-term management but not the immediate priority. Applying a pulse oximeter is not relevant to addressing the fruity breath odor and suspected ketoacidosis.
