Practice HESI Fundamentals Exam

Correct Answer: D

Rationale: Using surgical asepsis when performing nasal tracheal suctioning is crucial to prevent infection. Choice A is incorrect because the suction catheter should be held with the dominant hand to ensure better control and precision during the procedure. Choice B is incorrect as suctioning should be applied for no longer than 10 to 15 seconds to avoid trauma to the mucous membranes. Choice C is incorrect as the catheter should be disposed of properly after single-use to prevent cross-contamination and infection.

Correct Answer: C

Rationale: The correct answer is C. When using a two-wheeled walker, the client should stand with elbows slightly bent to maintain balance and stability. This position helps distribute weight effectively and promotes proper use of the walker. Choices A, B, and D are incorrect. Choice A does not demonstrate proper posture while using the walker. Choice B of picking up the walker with each step is not the correct technique and can lead to instability. Choice D of stooping slightly forward is also incorrect as it can affect balance and posture negatively.

Correct Answer: A

Rationale: Assessing for abdominal distention is crucial in this situation as it can indicate a complication with the shunt or fluid accumulation. Abdominal distention may suggest an issue with the shunt placement, such as obstruction or overdrainage, which requires immediate intervention. Maintaining the infant in an upright position (Choice B) is not the priority immediately postoperatively following a ventriculoperitoneal shunt placement. Beginning formula feedings when the infant is alert (Choice C) may be appropriate but is not the priority over assessing for abdominal distention. Pumping the shunt to assess for proper function (Choice D) is not a recommended nursing intervention postoperatively and should be done by a qualified healthcare provider.

Correct Answer: B

Rationale: The correct dosing schedule for the client to follow is to take the medication at 8 a.m., 4 p.m., and midnight. This timing spaces the doses evenly over the waking hours, ensuring consistent therapeutic levels of the medication. Choice A (9 a.m., 1 p.m., and 5 p.m.) does not evenly distribute the doses throughout the day. Choices C (Before breakfast, before lunch, and before dinner) and D (With breakfast, with lunch, and with dinner) do not provide the required frequency of dosing needed for optimal therapeutic effect.

Correct Answer: B

Rationale: Eating a light carbohydrate snack before bedtime is a suitable intervention for insomnia because it can help stabilize blood sugar levels and promote sleep. Exercising close to bedtime may actually disrupt sleep patterns due to increased alertness and body temperature. Drinking hot cocoa before bedtime, which contains caffeine, may interfere with falling asleep. Taking a nap during the day can make it harder to fall asleep at night and may worsen insomnia. Therefore, the best recommendation among the choices provided is to eat a light carbohydrate snack before bedtime.
