HESI CAT Exam 2022

HESI LPN

1. When caring for a client with Cushing syndrome, which serum laboratory value is most important for the nurse to monitor?

A. Lactate
B. Glucose
C. Hemoglobin
D. Creatinine

Correct answer: B

Rationale: When caring for a client with Cushing syndrome, monitoring glucose levels is crucial as Cushing syndrome often leads to hyperglycemia. Elevated glucose levels are a common manifestation of Cushing syndrome due to increased cortisol levels. Monitoring glucose helps in assessing and managing the client's condition effectively. Lactate levels are not typically affected by Cushing syndrome. Hemoglobin and creatinine levels are important for other conditions like anemia and kidney function, but they are not the priority in Cushing syndrome.

2. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

A. To reduce abdominal pressure on the diaphragm
B. To promote retraction of the intercostal accessory muscles of respiration
C. To promote bronchodilation and effective airway clearance
D. To decrease pressure on the medullary center which stimulates breathing

Correct answer: A

Rationale: Elevating the head of the bed to 30 degrees is done to reduce abdominal pressure on the diaphragm, aiding in lung expansion and oxygenation. This position helps improve respiratory mechanics by allowing the diaphragm to move more effectively. Choice B is incorrect as elevating the head of the bed does not directly promote retraction of the intercostal accessory muscles of respiration. Choice C is incorrect because although elevating the head of the bed can assist with airway clearance, its primary purpose in ARDS is to decrease pressure on the diaphragm. Choice D is incorrect because reducing pressure on the medullary center is not the main goal of elevating the head of the bed; the focus is on enhancing lung function and oxygen exchange.

3. A client is admitted with pyelonephritis, and cultures reveal an Escherichia coli infection. The client is allergic to penicillins, and the healthcare provider prescribed vancomycin IV. The nurse should plan to carefully monitor the client for which finding during IV administration?

A. Tissue sloughing upon extravasation
B. Elevated blood pressure and heart rate
C. Tinnitus and vertigo
D. Erythema of the face, neck, and chest

Correct answer: C

Rationale: The correct answer is C: Tinnitus and vertigo. Vancomycin can cause ototoxicity and nephrotoxicity, leading to symptoms like tinnitus and vertigo. Monitoring for these adverse effects is crucial to prevent further complications. Choices A, B, and D are incorrect because tissue sloughing, elevated blood pressure and heart rate, and erythema of the face, neck, and chest are not typically associated with vancomycin administration. Therefore, the nurse should focus on monitoring for signs of ototoxicity and nephrotoxicity such as tinnitus and vertigo.

4. The nurse discontinues a continuous IV heparin infusion for a male client on strict bedrest and is now preparing to administer the client's first dose of enoxaparin. Prior to giving this subcutaneous injection, which assessment finding requires additional intervention by the nurse?

A. Current lab report indicates an Aptt at 1.5 times the client's control
B. The client states that his right calf is aching and wants pain medication
C. The spouse is assisting the client who is shaving with an electric razor
D. Several bruised areas are noted on the client's upper extremities bilaterally

Correct answer: D

Rationale: The correct answer is D. Bruised areas on the client's upper extremities bilaterally indicate an increased risk of bleeding, which requires careful assessment before administering enoxaparin. Bruising suggests potential issues with clotting and hemostasis, making it crucial for the nurse to further evaluate the client's bleeding risk. Choices A, B, and C do not directly relate to the assessment of bleeding risk associated with enoxaparin administration and are therefore incorrect. Choice A provides information about the client's Aptt, which is not directly relevant to assessing bleeding risk for enoxaparin. Choice B addresses pain management, and Choice C involves the client's daily activities with no direct link to the bleeding risk assessment.

5. An adult male is admitted to the psychiatric unit from the emergency department because he is in the manic disorder. He has lost 10 pounds in the last two weeks and has not bathed in a week because he has been “trying to start a new business” and is “too busy to eat.” He is alert and oriented to time, place and person, but not situation. Which nursing diagnosis has the greatest priority?

A. Self-care deficit
B. Disturbed sleep pattern
C. Disturbed thought processes
D. Imbalanced nutrition

Correct answer: D

Rationale: Imbalanced nutrition is the priority in this case as the patient has lost a significant amount of weight and is neglecting self-care, such as bathing and eating properly. The weight loss indicates a serious issue that needs immediate attention to prevent further health complications. While self-care deficit, disturbed sleep pattern, and disturbed thought processes are also concerns for this patient, addressing the imbalanced nutrition takes precedence due to the potential impact on the patient's physical health. Neglecting proper nutrition can lead to serious complications, so it is crucial to address this issue first.
