HESI Practice Test for Fundamentals

Correct Answer: A

Rationale: During auscultation of the chest, normal breath sounds are the expected findings in a client who is newly admitted without respiratory complaints. Normal breath sounds indicate proper airflow through the airways without any abnormalities. Adventitious breath sounds (Choice B) refer to abnormal lung sounds such as crackles or wheezes, which are indicative of underlying respiratory issues. Absent breath sounds (Choice C) suggest a lack of airflow to a particular lung area, which could be due to conditions like pneumothorax. Diminished breath sounds (Choice D) indicate reduced airflow or consolidation in a specific lung region, often seen in conditions like pleural effusion or pneumonia. Therefore, in a newly admitted client without respiratory complaints, the nurse should expect to hear normal breath sounds during auscultation.

Correct Answer: A

Rationale: The correct precaution for Shigella infection is to wash hands thoroughly before and after contact with the client. Shigella is transmitted through the fecal-oral route, so hand hygiene is crucial in preventing its spread. Wearing a surgical mask or face shield is not necessary for Shigella as it is not primarily transmitted through respiratory droplets. While wearing a gown and gloves is important for standard precautions, the key precaution specific to Shigella is proper hand hygiene.

Correct Answer: D

Rationale: The correct answer is D. Removing the mobile when the baby starts to push up prevents choking hazards as infants can reach and grab objects posing a risk of choking. Choice A is unsafe as setting the water heater at 130�F can scald a child. Choice B is incorrect because even when a baby can sit up, they still require close supervision in the bathtub. Choice C is unsafe as current guidelines recommend placing babies on their backs to sleep to reduce the risk of sudden infant death syndrome (SIDS). Therefore, choices A, B, and C are incorrect or unsafe practices for infant care.

Correct Answer: D

Rationale: Fever in a client with rheumatoid arthritis can indicate an underlying infection or a more serious systemic involvement, such as vasculitis or inflammation of internal organs. These conditions can lead to serious complications and require immediate medical attention. Joint deformities and morning stiffness are common manifestations of rheumatoid arthritis itself and may not be indicative of an acute issue. Weight loss can be seen in chronic inflammatory conditions like rheumatoid arthritis but is not as concerning as fever, which suggests an acute process requiring prompt evaluation and intervention.

Correct Answer: B

Rationale: When a nurse asks a client to identify a number traced on the palm of the hand with their eyes closed, it assesses the client's ability to perceive touch sensations. This test specifically evaluates the tactile discrimination of the client. The other options do not test the client's ability to identify sensations accurately with eyes closed. Option A tests auditory perception, option C tests vibratory sense, and option D tests object recognition but not tactile discrimination, making them incorrect choices.
