HESI Fundamentals Exam

Correct Answer: A

Rationale: Monitoring hourly urine output is crucial after successful resuscitation from a pulseless dysrhythmia to assess kidney function and perfusion. The kidneys are particularly vulnerable to injury following cardiac events due to decreased perfusion during the event. Evaluating urine output hourly allows for early detection of renal impairment or inadequate organ perfusion. Option B, monitoring white blood cell count, is not a priority in this situation as it does not directly relate to immediate post-resuscitation care. Option C, checking blood glucose every 4 hours, is important but not as critical as assessing kidney function and perfusion. Option D, measuring temperature every 2 hours, is relevant for monitoring signs of infection or inflammatory response but is not as crucial as assessing kidney function in this scenario.

Correct Answer: A

Rationale: When a nurse suspects pediculosis capitis (head lice) upon noticing movement in the patient's hair, the correct action is to use gloves to inspect the hair. This protects the nurse from potential self-infestations. Applying a lindane-based shampoo immediately (Choice B) is not the first action, as diagnosis and confirmation are necessary before treatment. Shaving the patient's hair off (Choice C) is an extreme measure and is unnecessary at this stage. Ignoring the movement and continuing (Choice D) is negligent and can lead to the spread of infestation.

Correct Answer: A

Rationale: Administering a bronchodilator as prescribed is the most appropriate initial action for managing asthma-related shortness of breath. Bronchodilators help to open up the airways quickly, providing relief for the client. Encouraging deep breathing exercises may be beneficial in some situations but should not be the first action for acute shortness of breath in asthma. Positioning the client in high Fowler's position can also help improve breathing, but administering the bronchodilator takes precedence. Obtaining a peak flow reading is important in asthma management, but it is not the initial action needed to address acute shortness of breath.

Correct Answer: B

Rationale: The nurse should address the client's lack of understanding regarding the need for surgery first. Ensuring that the client comprehends the rationale for the procedure is essential for informed consent. Choices A, C, and D, while important, do not directly impact the client's understanding of the necessity of the surgery and can be addressed after clarifying the reason for the procedure.

Correct Answer: A

Rationale: The pulse deficit is calculated by finding the difference between the apical and radial pulse rates. In this case, the difference is 84 - 68 = 16. This indicates that there is a pulse deficit of 16 beats per minute. Choices B, C, and D are incorrect as they do not accurately reflect the difference between the two pulse rates.
