1. A nurse is caring for an infant with phenylketonuria (PKU). What diet should the nurse anticipate will be ordered by the health care provider?
- A. Fat-free
- B. Protein-enriched
- C. Phenylalanine-free
- D. Low-phenylalanine
Correct answer: D
Rationale: A low-phenylalanine diet is required for infants with PKU to prevent the buildup of phenylalanine, which can lead to brain damage.
2. A client reports new onset hearing loss bilaterally after taking a medication with known ototoxic effects. Which type of hearing loss should the nurse suspect?
- A. Conductive
- B. Sensorineural
- C. Mixed
- D. Central
Correct answer: B
Rationale: The correct answer is B: Sensorineural. Ototoxic medications can lead to sensorineural hearing loss by affecting the inner ear or auditory nerve. Conductive hearing loss is related to issues in the middle or outer ear, not typically caused by ototoxic medications. Mixed hearing loss is a combination of conductive and sensorineural components. Central hearing loss is related to the central nervous system, not commonly caused by ototoxic medications. Therefore, in this case, the nurse should suspect sensorineural hearing loss.
3. What is the most important action for the LPN/LVN to take to prevent infection in a client with an indwelling urinary catheter?
- A. Ensure the catheter tubing is free of kinks.
- B. Change the catheter every 72 hours.
- C. Clean the perineal area with an antiseptic solution daily.
- D. Irrigate the catheter with normal saline every shift.
Correct answer: A
Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This step helps prevent obstruction in the tubing, maintaining proper urine flow and reducing the risk of infection. Changing the catheter every 72 hours is not recommended unless clinically indicated, as routine changes can increase the risk of introducing pathogens. Cleaning the perineal area with an antiseptic solution is essential for general hygiene but does not directly prevent catheter-related infections. Irrigating the catheter with normal saline every shift is not a standard practice and can introduce microorganisms into the urinary tract, increasing the risk of infection.
4. The healthcare provider plans to assess a newborn and check the infant's Moro reflex. What is the healthcare provider evaluating?
- A. Neurological integrity
- B. Renal functioning
- C. Thermoregulation
- D. Respiratory adequacy
Correct answer: A
Rationale: The Moro reflex is an instinctive response observed in newborns, indicating their neurological integrity. This reflex is evaluated by eliciting a startle response in the infant, involving the sudden extension and abduction of the limbs, followed by their retraction. This assessment helps in determining the proper functioning of the infant's nervous system and brain. Choices B, C, and D are incorrect as they do not relate to the evaluation of the Moro reflex. Renal functioning pertains to kidney function, thermoregulation refers to temperature control, and respiratory adequacy involves assessing breathing and oxygenation levels, none of which are evaluated through the Moro reflex.
5. A client with schizophrenia is being treated with risperidone (Risperdal). The nurse notices that the client has a shuffling gait and tremors. What is the nurse's priority action?
- A. Administer a PRN dose of an anticholinergic medication.
- B. Document the findings and continue to monitor the client.
- C. Assess the client's blood glucose level.
- D. Notify the healthcare provider immediately.
Correct answer: A
Rationale: A shuffling gait and tremors may indicate extrapyramidal side effects (EPS) from risperidone. The nurse's priority action should be to administer an anticholinergic medication as it can help alleviate these symptoms associated with EPS. Documenting the findings and monitoring the client (Choice B) are important but addressing the immediate symptoms takes precedence. Assessing the client's blood glucose level (Choice C) is not directly related to the observed symptoms of shuffling gait and tremors. While notifying the healthcare provider (Choice D) is important, it is not the priority action when dealing with EPS symptoms.
