HESI Fundamentals Study Guide

Correct Answer: B

Rationale: Excessive moisture on the skin, as seen in a diaphoretic patient, can lead to impaired skin integrity. Diaphoresis softens epidermal cells, promotes bacterial growth, and can cause skin maceration. Afebrile status, strong pedal pulses, and adequate skin turgor are not directly associated with an increased risk of impaired skin integrity. Afebrile indicates the absence of fever, not a risk to skin integrity. Strong pedal pulses suggest good circulation, which is beneficial for skin health. Adequate skin turgor is a sign of good hydration and skin elasticity, indicating a lower risk of impaired skin integrity.

Correct Answer: C

Rationale: Contact precautions are necessary when caring for a client with a wound infection to prevent the spread of infection. Contact precautions involve practices such as wearing gloves and gowns, and ensuring proper hand hygiene. Airborne precautions are for diseases transmitted by small droplet nuclei that can remain suspended in the air, like tuberculosis. Droplet precautions are for diseases transmitted through respiratory droplets larger than 5 microns, such as influenza. Standard precautions are used for all clients to prevent the spread of infection and include practices like hand hygiene, use of personal protective equipment, and safe injection practices. In this case, since the client has a wound infection, the nurse should focus on implementing contact precautions to reduce the risk of spreading the infection to themselves or others.

Correct Answer: C

Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.

Correct Answer: A

Rationale: The most important action for the LPN/LVN to take when a client with a history of diabetes mellitus experiences symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps assess the severity of hyperglycemia and guides further interventions. Encouraging the client to increase fluid intake (Choice B) may exacerbate the symptoms by further diluting the blood glucose concentration. Administering insulin as prescribed (Choice C) should be done based on the healthcare provider's orders and after assessing the blood glucose levels. Assessing the client's urine output (Choice D) is important but not the most immediate action needed in this scenario.

Correct Answer: B

Rationale: A client with Guillain-Barre syndrome in a non-responsive state with stable vital signs and independent breathing would most accurately be described by a Glasgow Coma Scale of 8 with regular respirations. Choice A is incorrect as 'comatose' implies a deeper level of unconsciousness than described in the scenario. Choice C is incorrect as 'appears to be sleeping' is not an accurate description of a non-responsive state. Choice D is incorrect as a Glasgow Coma Scale of 13 indicates a higher level of consciousness than stated in the scenario.
