HESI Fundamentals Study Guide

Correct Answer: A

Rationale: The correct answer is A: Hypotension. Heat stroke is characterized by elevated body temperature, which can lead to hypotension (low blood pressure) due to dehydration and vasodilation. Bradycardia (slow heart rate) and clammy skin are not typical findings in heat stroke. Bradypnea (slow breathing) is also not a common feature of heat stroke. Therefore, hypotension is the most likely cardiovascular manifestation seen in a client with heat stroke.

Correct Answer: B

Rationale: Enoxaparin is a medication that is administered subcutaneously, which means it should be injected into the fatty tissue layer beneath the skin. Administering enoxaparin at a 90-degree angle ensures proper absorption and reduces the risk of injecting the medication into muscle tissue, which could affect its effectiveness. Injecting the medication at a 45-degree angle may lead to improper absorption as it may not reach the subcutaneous tissue adequately. Injecting the medication into the muscle instead of subcutaneously can alter the absorption rate and therapeutic effects. Pinching the skin before injecting is not necessary for administering enoxaparin subcutaneously and may cause unnecessary discomfort to the client.

Correct Answer: B

Rationale: In this scenario, the LPN should continue asking the mother questions about the child. The mother's behavior of looking at the floor may be a cultural practice, such as avoiding direct eye contact, which should be respected. By maintaining the conversation with the mother, the nurse acknowledges and respects her communication style, fostering trust and open dialogue. Option A is not the best choice as it may disregard the cultural context and the importance of the mother's input. Option C is unnecessary as the LPN can effectively handle the situation. Option D could be perceived as insensitive and may disrupt the rapport between the nurse and the mother.

Correct Answer: D

Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.

Correct Answer: A

Rationale: A testicular examination is appropriate for a 20-year-old male to screen for testicular cancer, which is more common in younger age groups. Testicular cancer is most frequently diagnosed in individuals between the ages of 15 and 40. Blood glucose screening is typically recommended for older individuals or those at risk for diabetes. Fecal occult blood testing is used for colorectal cancer screening, usually starting at age 50. Prostate-specific antigen testing is commonly considered for prostate cancer screening in older males, typically around age 50. Therefore, the most appropriate screening for the 20-year-old client is the testicular examination.
