HESI CAT Exam Questions
Question 1 of 9
The parents of a 6-year-old recently diagnosed with asthma should be taught that the symptom of acute episodes of asthma is due to which physiological response?
Correct Answer: A
Rationale: The correct answer is A: Inflammation of the mucous membrane & bronchospasm. Acute asthma episodes are primarily caused by inflammation of the airways and bronchospasm, which lead to airway obstruction. Increased mucus production and bronchoconstriction (Choice B) are part of the physiological responses in asthma but do not directly cause acute episodes. Allergic reactions and hyperventilation (Choice C) are related to asthma triggers and responses but are not the direct causes of acute episodes. Airway narrowing and decreased lung capacity (Choice D) are consequences of inflammation and bronchospasm but do not explain the physiological response leading to acute asthma episodes.
Question 2 of 9
The client enters the room of a client with Parkinson's disease who is taking carbidopa-levodopa. The client is arising slowly from the chair while the unlicensed assistive personnel (UAP) stands next to the chair. What action should the nurse take?
Correct Answer: A
Rationale: The correct action for the nurse to take in this situation is to demonstrate how to help the client move more efficiently. As the client is arising slowly from the chair, providing guidance on proper movement techniques can improve the client's mobility and safety. Offering a PRN analgesic (Choice B) is not relevant to the client's situation as there is no indication of pain. Affirming that the client should arise slowly (Choice C) does not address the need for assistance in improving movement efficiency. Instructing the UAP to assist the client in moving more quickly (Choice D) may compromise the client's safety and is not the appropriate action to take.
Question 3 of 9
The client demonstrates an understanding of sliding scale insulin administration instructions by performing the procedure in which order?
Correct Answer: A
Rationale: The correct order for the client to perform the procedure is to first obtain the blood glucose level. This step is crucial as it helps determine the appropriate dose of insulin based on the sliding scale. Verifying the insulin prescription, drawing insulin into the syringe, and cleansing the selected site are important steps in the process but should follow after obtaining the blood glucose level. Therefore, options B, C, and D are incorrect in terms of the initial steps required for sliding scale insulin administration.
Question 4 of 9
A 9-year-old received a short arm cast for a right radius. To relieve itching under the child's cast, which instructions should the nurse provide to the parents?
Correct Answer: A
Rationale: Blowing cool air from a hair dryer under the cast is a safe method to relieve itching without damaging the cast or causing injury. The air helps to dry out the moisture that is causing the itching. Twisting the cast back and forth (choice B) can create pressure points and discomfort for the child. Shaking powder into the cast (choice C) can introduce foreign material that may cause skin irritation. Pushing a pencil under the cast edge (choice D) can injure the child's skin or even dislodge the cast.
Question 5 of 9
The nurse notes that an older adult client has a moist cough that increases in severity during and after meals. Based on this finding, what action should the nurse take?
Correct Answer: D
Rationale: The correct answer is D. The moist cough that worsens during and after meals suggests possible dysphagia, a condition related to swallowing difficulties. Requesting a consultation for dysphagia is essential for an accurate diagnosis and appropriate management. Encouraging the client to perform deep breathing exercises (choice A) may not address the underlying issue of dysphagia. Offering additional clear fluids (choice B) may not be appropriate for someone with swallowing difficulties. Collecting a sputum specimen (choice C) is not the priority in this scenario as the focus should be on identifying and managing the swallowing problem.
Question 6 of 9
A client complains of paresthesia in the fingers and toes and experiences hand spasms when the blood pressure cuff is inflated. Which serum laboratory finding should the nurse expect to find when assessing the client?
Correct Answer: C
Rationale: The correct answer is C: Low serum calcium. Hand spasms and paresthesia are indicative of potential hypocalcemia, which is characterized by low serum calcium levels. Elevated serum calcium (Choice A) is not consistent with the symptoms described. Low serum magnesium (Choice B) and elevated serum potassium (Choice D) are not typically associated with hand spasms and paresthesia.
Question 7 of 9
Which techniques should be used to administer an intradermal (ID) injection for a Mantoux test to screen for tuberculosis (TB)? Select all that apply.
Correct Answer: A
Rationale: Observing for an intradermal bleed after the antigen is injected is a proper technique for an ID injection. This is important to confirm the correct placement of the injection. Choice B is correct because the recommended site for an ID injection for a Mantoux test is the volar surface of the forearm. Choice C is incorrect because the standard needle size for an ID injection is usually 26 or 27 gauge with a length of 1/4 to 5/8 inches, not 25 gauge with a length of 1/2 inch. Choice D is incorrect because the needle should be inserted into the skin with the bevel facing up, not down.
Question 8 of 9
Which client requires careful nursing assessment for signs and symptoms of hypomagnesemia?
Correct Answer: A
Rationale: The correct answer is A. Vomiting can lead to significant loss of magnesium, causing hypomagnesemia. In this scenario, the young adult client with intractable vomiting from food poisoning is at higher risk of developing hypomagnesemia due to the loss of magnesium through vomiting. Choices B, C, and D are less likely to present with hypomagnesemia. Hyperparathyroidism (B) is associated with hypercalcemia, renal failure (C) can lead to hypermagnesemia, and overconsumption of simple carbohydrates (D) is not directly linked to magnesium imbalances.
Question 9 of 9
An adult male who admits to abusing IV drugs obtains the results of HIV testing. When informed that the results are positive, he states that he does not want his wife to know. What action should the nurse take?
Correct Answer: B
Rationale: The nurse should counsel the client on the importance of notifying partners about HIV status while respecting confidentiality. Mandatory partner notification laws vary by jurisdiction, so option A cannot be universally applied. Breaching patient confidentiality, as suggested in option C, is unethical. Reporting the client's status to the health department without consent, as in option D, is not appropriate as HIV status is confidential information and is not automatically reported as a sexually transmitted case.
