HESI Fundamental Practice Exam

Correct Answer: A

Rationale: Administering oxygen via a nasal cannula is the priority action for a client experiencing chest pain due to coronary artery disease. Oxygen therapy helps improve oxygenation, reduce myocardial workload, and relieve chest pain by increasing oxygen delivery to the heart muscle. While measuring vital signs, obtaining a 12-lead ECG, and encouraging pursed-lip breathing are important interventions, administering oxygen takes precedence in this situation to address the potential hypoxemia associated with chest pain in a client with a history of coronary artery disease.

Correct Answer: C

Rationale: Tuberculosis is transmitted through airborne particles, so airborne precautions are necessary to prevent the spread of the disease. Airborne precautions (Choice C) involve measures such as negative pressure rooms and N95 respirators to prevent the transmission of infectious agents that remain infectious over long distances when suspended in the air. Contact precautions (Choice A) are used for diseases that spread through direct contact with the patient or their environment. Droplet precautions (Choice B) are for diseases transmitted through respiratory droplets, typically over short distances. Protective environment (Choice D) is used for clients who are immunocompromised to protect them from environmental pathogens, not for diseases like tuberculosis that spread through the air.

Correct Answer: A

Rationale: In end-of-life care, providing comfort and emotional support is essential. Sitting with the client, holding their hand, and offering a compassionate presence can help the client feel supported during a difficult time. Asking why the client is crying may not always be necessary as the focus should be on providing comfort rather than probing for information. Leaving the room to provide privacy or just administering medications and leaving may neglect the client's emotional needs and miss an opportunity to provide holistic care.

Correct Answer: A

Rationale: The correct action for the nurse to take is to remove the client's stockings at least once during each shift. This is important to inspect the skin and prevent complications such as pressure injuries or impaired circulation. Rolling the top of the stockings down can compromise their effectiveness in preventing blood clots. Seating the client in a chair prior to applying stockings is not directly related to the care of anti-embolic stockings. Measuring the length of the client's leg from the heel to the gluteal fold is not necessary for the application or care of knee-length anti-embolic stockings.
