HESI Fundamentals Study Guide

Correct Answer: C

Rationale: During puberty in males, the first physical change that typically occurs is the enlargement of the testes and scrotum. This change is due to increased production of testosterone, which stimulates growth and development of the genital organs. The appearance of downy hair on the upper lip (Choice A) and hair growth in the axillae (Choice B) usually follow the enlargement of the testes and scrotum. Deepening of the voice (Choice D) is a later stage change that occurs during puberty as the larynx (voice box) grows and the vocal cords lengthen and thicken.

Correct Answer: A

Rationale: Checking the client for injuries is the priority when finding them on the bathroom floor. This action ensures the client's safety as it allows for immediate assessment of any potential harm. Calling for help may be necessary, but assessing for injuries takes precedence to address any immediate threats to the client's well-being. Moving the client to a sitting position or assisting them back to bed should only be done after ensuring there are no serious injuries requiring prompt medical attention. Therefore, the correct first action is to check the client for injuries.

Correct Answer: A

Rationale: When assessing breath sounds in a client with pneumonia, the nurse should follow a systematic pattern from side-to-side moving down the client's chest. This approach ensures a comprehensive evaluation of breath sounds across different lung fields. Asking the client to breathe in deeply through their nose (Choice B) is not necessary for assessing breath sounds. Instructing the client to sit upright with their head slightly tilted backward (Choice C) is not directly related to assessing breath sounds and may not be required. Placing the diaphragm of the stethoscope on the client's chest (Choice D) is not the correct technique for auscultating breath sounds, as the diaphragm should be used for this purpose.

Correct Answer: A

Rationale: Assigning an admission with atrial fibrillation and heart failure to a PN is not appropriate. This complex case requires more advanced skills and should not be managed by a PN without adequate support. The PN may not have the necessary training or expertise to handle such a critical situation effectively. Choice B is a suitable assignment for a PN nursing student as they can handle a client who had a major stroke 6 days ago. Choice C is also appropriate as a child with burns receiving packed cells and albumin IV running can be managed by the charge nurse. Choice D is within the scope of practice for a UAP since an elderly client post-myocardial infarction a week ago may require basic care and assistance.

Correct Answer: A

Rationale: In a situation where a client is found unresponsive on the floor, the nurse's first priority is to establish an airway. This is crucial to ensure that the client can breathe adequately and receive oxygen. Without a patent airway, the client's oxygenation and ventilation may be compromised, leading to serious consequences. Calling for assistance is important, but establishing an airway takes precedence as it directly impacts the client's ability to breathe. Checking the client's pulse and blood pressure can be done after ensuring a clear airway. Performing CPR is not the immediate action needed unless the client's breathing and pulse are absent after the airway has been secured.
