Practice HESI Fundamentals Exam

Correct Answer: A

Rationale: The Romberg test is used to assess a client's balance by evaluating their ability to maintain a steady posture with eyes closed. The heel-to-toe walk is another assessment that tests balance by assessing gait and coordination. The Snellen test is used to assess visual acuity and is unrelated to balance. Testing spinal accessory function involves assessing the movement of the head and shoulders and is not directly related to balance assessment.

Correct Answer: A

Rationale: Acknowledging that the client's wife is supporting the arm correctly is the appropriate nursing action in this scenario. By doing so, the nurse reinforces correct technique and promotes confidence. Choice B is incorrect as the issue is not about maintaining warmth. Choice C is incorrect as gripping directly under the joint is not necessary in this case. Choice D is incorrect as instructing to grip directly over the joint may not provide the best support for passive range-of-motion exercises.

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: B

Rationale: Instructing the client to follow a finger through the six cardinal positions of gaze is the correct action to assess extraocular eye movements effectively. This technique evaluates the function of the six extraocular muscles and cranial nerves III, IV, and VI. Positioning the client 6.1 m away from the Snellen chart is more relevant for visual acuity testing. Asking the client to cover their right eye during the assessment is not necessary for evaluating extraocular movements. Holding a finger at a specific distance in front of the client's eye is not an appropriate method for assessing extraocular eye movements.

Correct Answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.
