HESI PN Exit Exam 2024

Correct Answer: C

Rationale: Notifying the charge nurse promptly is the priority when a bedfast client is dyspneic. Dyspnea can indicate a serious problem that requires immediate assessment and intervention. Contacting the charge nurse ensures timely assistance and appropriate actions to address the client's condition. Applying a pulse oximeter or measuring blood pressure may provide valuable data, but the priority is prompt communication with the charge nurse to ensure quick intervention. Observing pressure areas, while important for overall client care, is not the most immediate action needed when a client is experiencing dyspnea.

Correct Answer: A

Rationale: The Guthrie test is specifically designed to screen newborns for phenylketonuria (PKU), a metabolic disorder that can lead to intellectual disability if left untreated. Phenylketonuria is caused by the deficiency of an enzyme required to metabolize the amino acid phenylalanine. Screening for PKU in newborns is crucial as early diagnosis and intervention can prevent the severe consequences associated with the condition. Choices B, C, and D are incorrect as the Guthrie test is not used to screen for cystic fibrosis, Down syndrome, or sickle cell anemia.

Correct Answer: A

Rationale: A 9-year-old child typically loses their central incisors, not the lateral incisors or second molars. The central incisors are usually among the first teeth that children lose around 6 to 7 years of age, as part of the natural process of shedding primary teeth to make way for permanent teeth. The second molars and cuspids are typically lost later in the mixed dentition phase. Therefore, option A, 'Central incisor,' is the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Lyme disease. The "bull's eye" rash, or erythema migrans, is a hallmark of early Lyme disease, caused by the bacterium Borrelia burgdorferi. Choice B, Rocky Mountain spotted fever, presents with a different type of rash. Choice C, Syphilis, typically presents with a painless ulcer and rash but not a "bull's eye" rash. Choice D, Toxoplasmosis, does not typically present with a "bull's eye" rash.

Correct Answer: C

Rationale: The correct answer is C. In 90-90 traction, the weights should hang freely and not touch the foot of the bed to maintain proper traction and bone alignment. Option A is not necessarily a concern as bowel movements can be influenced by various factors, including diet changes and pain medication. Option B indicates good caregiver involvement, promoting comfort and preventing complications. Option D demonstrates neurovascular function, which is a positive finding. Therefore, the weights touching the foot of the bed is the finding that requires immediate attention to ensure the effectiveness of the traction.
