Practice HESI Fundamentals Exam

Correct Answer: B

Rationale: The most appropriate initial approach to correct the behavior of improper hand washing by a staff nurse is to discuss what the nurse knows about proper hand hygiene. This approach helps in identifying any knowledge gaps the nurse may have and provides an opportunity to educate and correct the behavior. Option A is not the best choice as simply reminding the nurse about the importance of hand washing may not address the underlying issue of knowledge or technique. Option C, providing a review of the hand washing policy, may be necessary but is not the most immediate step to take. Option D, referring the nurse to the infection control nurse, is premature and may not be necessary if the issue can be resolved through education and communication first.

Correct Answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.

Correct Answer: A

Rationale: Correct Answer: Large doses of acetaminophen can cause liver damage, which is a known adverse effect of the medication. Acetaminophen is metabolized in the liver, and excessive amounts can overwhelm the liver's ability to process it, leading to hepatotoxicity. Renal failure (Choice B) is not typically associated with acetaminophen use. Gastric bleeding (Choice C) is more commonly linked to nonsteroidal anti-inflammatory drugs (NSAIDs) rather than acetaminophen. Heart attack (Choice D) is not a recognized adverse effect of acetaminophen, which primarily affects the liver when taken in large amounts.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin. Monitoring hemoglobin levels is essential to assess the effectiveness of epoetin alfa in clients with chronic kidney disease. Epoetin alfa is a medication that stimulates red blood cell production, aiming to increase hemoglobin levels and improve symptoms of anemia in these patients. Monitoring serum potassium (Choice A) is important in clients with kidney disease, but it is more related to assessing electrolyte balance rather than the direct effectiveness of epoetin alfa. Serum creatinine (Choice C) and blood urea nitrogen (Choice D) are kidney function tests that help evaluate kidney health but do not specifically reflect the effectiveness of epoetin alfa therapy.

Correct Answer: D

Rationale: The correct answer is D: 'Report any signs of infection to the healthcare provider immediately.' Methotrexate is an immunosuppressant medication commonly used to treat rheumatoid arthritis. It can lower the immune system's ability to fight infections, making it crucial for clients to promptly report any signs of infection to prevent serious complications. Choices A, B, and C are incorrect because avoiding sunlight, taking the medication with food, and increasing fluid intake are not specific to methotrexate therapy and are not primary concerns associated with this medication.
