HESI RN
HESI Medical Surgical Specialty Exam
1. When preparing to examine a client’s skin using a Wood light, what should the nurse do to facilitate this procedure?
- A. Darken the examining room
- B. Administer a local anesthetic
- C. Obtain a signed informed consent
- D. Shave the skin and scrub it with povidone-iodine (Betadine)
Correct answer: A
Rationale: When using a Wood light to examine the skin, the nurse should darken the examining room. This is necessary because the Wood light emits long-wavelength UV light, which is better visualized in a darkened environment. Administering a local anesthetic (Choice B) is not needed for this procedure. Obtaining a signed informed consent (Choice C) is not directly related to using a Wood light for skin examination. Shaving the skin and scrubbing it with povidone-iodine (Betadine) (Choice D) is not required and may not be appropriate for this type of skin examination.
2. A school-age child with a history of type 1 diabetes mellitus is brought to the emergency department with confusion and rapid breathing. The practical nurse (PN) suspects diabetic ketoacidosis (DKA). Which initial intervention should the PN anticipate?
- A. Administer subcutaneous insulin.
- B. Give oral glucose tablets.
- C. Start intravenous fluids.
- D. Administer oxygen therapy.
Correct answer: C
Rationale: Intravenous fluids are typically the initial intervention in diabetic ketoacidosis (DKA) to treat dehydration and stabilize the patient's condition. The fluid replacement helps correct electrolyte imbalances and improve perfusion, which are crucial in managing DKA. Insulin therapy follows after fluid resuscitation to address the underlying cause of DKA, which is the lack of insulin leading to increased ketone production. Administering subcutaneous insulin (Choice A) would be premature without first addressing the dehydration and electrolyte imbalances. Giving oral glucose tablets (Choice B) is contraindicated in DKA as the patient already has high blood glucose levels. Administering oxygen therapy (Choice D) may be necessary based on the patient's condition, but addressing dehydration with intravenous fluids is the priority intervention in DKA.
3. When caring for a child with Kawasaki disease, which symptom is the most significant for making this diagnosis?
- A. Desquamation of the palms and soles.
- B. Cervical lymphadenopathy.
- C. Erythema of the hands and feet.
- D. Strawberry tongue.
Correct answer: C
Rationale: Erythema of the hands and feet is a key diagnostic criterion for Kawasaki disease. This, along with other symptoms like fever and strawberry tongue, helps in making the diagnosis. While desquamation of the palms and soles, cervical lymphadenopathy, and strawberry tongue are associated with Kawasaki disease, the presence of erythema of the hands and feet is particularly significant in diagnosing this condition.
4. A client wants to increase her daily intake of omega-3 fatty acids. Which of the following foods should the nurse suggest the client increase?
- A. Blueberries
- B. Soybean oil
- C. Citrus fruits
- D. Green tea
Correct answer: B
Rationale: The correct answer is B: Soybean oil. Soybean oil is a good source of omega-3 fatty acids, which are beneficial for heart health. Blueberries (choice A), citrus fruits (choice C), and green tea (choice D) are not significant sources of omega-3 fatty acids. Blueberries are rich in antioxidants, citrus fruits provide vitamin C, and green tea contains polyphenols, but they do not offer a substantial amount of omega-3 fatty acids compared to soybean oil.
5. What is Diazepam used for?
- A. Management of post-partum hemorrhage.
- B. Management of pre-eclampsia.
- C. Induction of labor.
- D. Relieving anxiety.
Correct answer: D
Rationale: Diazepam is primarily used for relieving anxiety and muscle spasms. It is a benzodiazepine medication that works by enhancing the effects of a neurotransmitter in the brain to produce a calming effect. While Diazepam is not used for managing post-partum hemorrhage, pre-eclampsia, or inducing labor, it is essential in treating anxiety disorders, muscle spasms, and certain types of seizures. Therefore, option D is the correct answer as it aligns with the primary therapeutic use of Diazepam.
