HESI Fundamentals 2023 Test Bank

Correct Answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

Correct Answer: D

Rationale: Elevated temperature is the correct finding to report immediately in a client with a history of peptic ulcer disease and abdominal pain. This could indicate a perforation or worsening of the condition, requiring prompt medical attention. Positive bowel sounds (Choice A) are a normal finding and not a cause for concern. Rebound tenderness (Choice B) is concerning but does not require immediate attention compared to an elevated temperature. Increased appetite (Choice C) is not a red flag symptom for peptic ulcer disease and can be considered a positive sign, not requiring immediate attention.

Correct Answer: D

Rationale: The correct answer is D: Contact precautions. When a client has an abdominal wound with purulent drainage, contact precautions are necessary to prevent the spread of infection through direct contact. Protective environment precautions are used for immunocompromised clients, airborne precautions are for diseases transmitted by airborne particles, and droplet precautions are for diseases transmitted by respiratory droplets. In this case, the focus is on preventing direct contact transmission, making contact precautions the most appropriate choice. Protective environment, airborne, and droplet precautions are not indicated in this scenario because the primary concern is the direct contact transmission of pathogens through the wound drainage.

Correct Answer: C

Rationale: When a nurse obtains a blood pressure reading that is elevated, the appropriate action is to recheck the client's BP and measure the other arm for comparison. This step helps ensure accuracy by ruling out errors like improper cuff size, positioning, or equipment malfunction. Repositioning the client supine is not necessary unless the client shows signs of distress or symptoms. Ensuring the appropriate cuff width is important for accurate readings but does not address the immediate need to confirm the current BP. Requesting another nurse to check the BP in 30 minutes delays immediate action and does not address the need for verification and comparison of the current reading.

Correct Answer: D

Rationale: The correct instruction for a UAP caring for a client with MRSA under contact precautions is to don a gown and gloves when entering the room. Wearing a gown and gloves is necessary to prevent the transmission of MRSA. Choice A is incorrect because visitors may be allowed with proper precautions in place. Choice B is incorrect as it assumes the client has body fluid precautions, which is not specified. Choice C is incorrect as it does not address the UAP's protective measures but rather focuses on the client wearing a mask.
