HESI Fundamentals Exam

Correct Answer: A

Rationale: The correct action for the LPN/LVN to implement is to give an around-the-clock schedule for administration of analgesics. This approach helps maintain consistent pain management by providing the medication regularly, preventing the pain from becoming severe. Choice B is incorrect because waiting for severe pain before administering the analgesic may lead to uncontrolled pain levels. Choice C is inappropriate as the goal of pain management in hospice care is to provide comfort without unnecessary sedation. Choice D is also incorrect as offering a medication-free period may result in inadequate pain control for the client.

Correct Answer: A

Rationale: Performing a bladder scan is the initial step to assess for urinary retention in a postoperative client. This non-invasive technique helps determine the volume of urine in the bladder, guiding further interventions. Encouraging the client to drink fluids (Choice B) may be beneficial but is not the priority when assessing for urinary retention. Inserting a straight catheter (Choice C) should not be the initial action without first assessing for retention. Administering a diuretic (Choice D) should not be done without confirming the need through assessment.

Correct Answer: B

Rationale: The correct way to transcribe the dosage of three tenths of a milligram of levothyroxine IV STAT is 0.3 mg. When expressing decimals less than 1, there should be a leading zero before the decimal point. Choice A is incorrect (.3 mg) because it lacks the leading zero. Choice C (0.30 mg) is incorrect as it includes a trailing zero after the decimal point, which is unnecessary. Choice D (3/10 mg) is incorrect as it presents the dosage as a fraction, which is not the standard format for transcribing medication dosages. Therefore, B (0.3 mg) is the most appropriate and accurate way to document this prescription on the client's medical record.

Correct Answer: C

Rationale: The correct technique for using a flow-oriented incentive spirometer involves breathing in slowly and deeply to raise the ball or piston. This action helps to expand the lungs and improve lung function. Option A is incorrect as coughing deeply after each use is not part of using the spirometer. Option B is incorrect as holding the breath for 10 seconds is not the correct instruction for using the spirometer. Option D is incorrect as exhaling forcefully before using the spirometer is not the appropriate step in using this device.

Correct Answer: A

Rationale: When a nurse suspects pediculosis capitis (head lice) upon noticing movement in the patient's hair, the correct action is to use gloves to inspect the hair. This protects the nurse from potential self-infestations. Applying a lindane-based shampoo immediately (Choice B) is not the first action, as diagnosis and confirmation are necessary before treatment. Shaving the patient's hair off (Choice C) is an extreme measure and is unnecessary at this stage. Ignoring the movement and continuing (Choice D) is negligent and can lead to the spread of infestation.
