HESI Quizlet Fundamentals Questions
Question 1 of 5
Twenty minutes after beginning a heat application, the client states that the heating pad no longer feels warm enough. What is the best response by the nurse?
Correct Answer: D
Rationale: Choice (D) describes thermal adaptation, which occurs 20 to 30 minutes after heat application. The body's receptors adjust to the constant heat exposure, leading to a decreased sensation of warmth. Choices (A) and (B) provide inaccurate information regarding the situation, while choice (C) is not physiologically sound and could potentially harm the client by increasing the temperature unnecessarily.
Question 2 of 5
The nurse is preparing a client for surgery. What action is most important for the nurse to take?
Correct Answer: A
Rationale: Ensuring that the client signs the consent form (A) is the most crucial action before surgery. The consent form is legally and ethically necessary for the procedure to proceed. While reviewing allergies (B), confirming identity (C), and verifying the surgical site (D) are essential steps, obtaining the client's informed consent takes precedence to protect the client's rights and ensure a safe surgical experience.
Question 3 of 5
What is the most important instruction for the nurse to provide a client with a new colostomy regarding stoma care?
Correct Answer: C
Rationale: Measuring the stoma using a stoma guide (C) is crucial as it ensures that the appliance fits properly, which is essential for preventing skin irritation and leakage. Proper measurement helps in selecting the right size of the appliance, promoting comfort and optimal stoma care. In contrast, cleansing with hydrogen peroxide (A), applying a moisture barrier cream (B), and using a dry gauze pad (D) are important but not as critical as ensuring the correct fit of the stoma appliance.
Question 4 of 5
A client with a history of myocardial infarction (MI) is admitted with chest pain. Which laboratory test should the nurse expect to be ordered to determine if the client is experiencing another MI?
Correct Answer: A
Rationale: Troponin is the most specific and sensitive laboratory test for detecting myocardial infarction (MI). It is released when there is damage to the heart muscle, making it a valuable marker for diagnosing another MI. Myoglobin and CK-MB can also be elevated in MI, but troponin is preferred due to its higher specificity. C-reactive protein is a marker of inflammation and not specific to MI.
Question 5 of 5
A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dL. What type of insulin should the nurse prepare to administer to this client?
Correct Answer: A
Rationale: In a client with a blood glucose level of 600 mg/dL, which indicates severe hyperglycemia or diabetic ketoacidosis, the nurse should prepare to administer regular insulin (A). Regular insulin has a rapid onset of action and is the preferred choice for immediate correction of high blood glucose levels. NPH insulin (B), lispro insulin (C), and glargine insulin (D) are not suitable for the rapid correction of severe hyperglycemia.
