HESI CAT Exam 2024

HESI LPN

1. The nurse is assessing a 3-month-old infant who had a pylorotomy yesterday. This child should be medicated for pain based on which finding?

A. Restlessness
B. Clenched Fist
C. Increased pulse rate
D. Increased respiratory rate

Correct answer: A

Rationale: In infants, restlessness can be a significant indicator of discomfort or pain, necessitating appropriate pain management. While choices B, C, and D can also be associated with pain, restlessness is a more general and reliable indicator in this scenario. A clenched fist might indicate pain or distress, but it is not as specific as restlessness in assessing pain in infants. Increased pulse rate and respiratory rate can be influenced by various factors other than pain, making them less reliable indicators of pain in this context.

2. A client receiving chemotherapy has severe neutropenia. Which snack is best for the nurse to recommend to the client?

A. Plain yogurt sweetened with raw honey
B. Peanuts in the shell, roasted or unroasted
C. Aged farmer’s cheese with celery sticks
D. Baked apples topped with dried raisins

Correct answer: A

Rationale: The correct answer is A: Plain yogurt sweetened with raw honey. This option is the best choice for a client with severe neutropenia undergoing chemotherapy because it is less likely to harbor harmful bacteria, which could cause infections due to the weakened immune system. Peanuts in the shell (choice B) may carry a risk of contamination, while aged farmer's cheese with celery sticks (choice C) and baked apples topped with dried raisins (choice D) may not be as safe as plain yogurt for a client with severe neutropenia.

3. After witnessing a preoperative client sign the surgical consent form, what are the legal implications of the nurse's signature on the client's form as a witness?

A. The client voluntarily grants permission for the procedure to be done
B. The surgeon has explained to the client why the surgery is necessary
C. The client is competent to sign the consent without impairment of judgment
D. The client understands the risks and benefits associated with the procedure

Correct answer: C

Rationale: The nurse's signature on the consent form signifies that the client is competent to sign the consent without impairment of judgment. This legal implication ensures that the client possesses the necessary capacity to make decisions about their healthcare. Choice A is incorrect because the nurse's signature does not imply the client's voluntary permission for the procedure. Choice B is incorrect as it pertains to the surgeon's responsibility, not the nurse's. Choice D is incorrect as the nurse's signature does not confirm the client's understanding of the risks and benefits associated with the procedure.

4. A client with chronic kidney disease has an arteriovenous (AV) fistula in the left forearm. Which observation by the nurse indicates that the fistula is patent?

A. Distended, tortuous veins in the left hand
B. The left radial pulse is 2+ bounding
C. Auscultation of a thrill on the left forearm
D. Assessment of a bruit on the left forearm

Correct answer: C

Rationale: Auscultation of a thrill on the left forearm is the correct observation indicating that the AV fistula is patent. A thrill is a palpable vibration or buzzing sensation felt over the fistula, indicating the presence of blood flow. Choices A, B, and D do not directly assess the patency of the fistula. Distended, tortuous veins in the left hand may indicate venous hypertension; a bounding radial pulse could suggest increased blood flow through an artery, but it does not confirm fistula patency; assessment of a bruit indicates turbulent blood flow, but it does not confirm patency.

5. A client presents to the healthcare provider with fatigue, poor appetite, general malaise, and vague joint pain that improves mid-morning. The client has been using over-the-counter ibuprofen for several months. The healthcare provider makes an initial diagnosis of rheumatoid arthritis (RA). Which laboratory test should the nurse report to the healthcare provider?

A. Sedimentation rate
B. White blood cell count
C. Anti–CCP antibodies
D. Activated Clotting Time

Correct answer: A

Rationale: The correct answer is A: Sedimentation rate. Sedimentation rate, Anti–CCP antibodies, and C-reactive protein are commonly used laboratory tests to indicate inflammation and help diagnose rheumatoid arthritis. An elevated sedimentation rate is a nonspecific indicator of inflammation in the body, which is often seen in RA. White blood cell count is not specific for RA and is not typically significant in the diagnosis. Anti–CCP antibodies are specific to RA and are useful in confirming the diagnosis. Activated Clotting Time is not relevant to the diagnosis of rheumatoid arthritis as it is not specific to this condition.
