HESI PN Exit Exam 2024
1. The nurse is assisting with the admission of a young adult female Korean exchange student with acute abdominal pain. Although the client has been able to easily answer questions, when asked about sexual activity, she looks away. What action should the nurse take?
- A. Omit the section of the assessment form
- B. Ask her if she would like an interpreter to help her understand the question
- C. Reword the question to make it more culturally sensitive
- D. Observe the client's response when asked a different question
Correct answer: D
Rationale: Observing the client's response to another question is the most appropriate action in this scenario. By doing so, the nurse can assess whether the client's discomfort is due to cultural sensitivity or a misunderstanding. This approach allows the nurse to proceed with sensitivity and respect, ensuring effective communication. Option A is incorrect because omitting the section of the assessment form may result in missing crucial information relevant to the client's condition. Option B jumps to assumptions about a language barrier without confirming it first. Option C focuses on rewording the question without addressing the underlying issue causing the client's discomfort, which may not necessarily be due to a lack of understanding.
2. What is the primary function of surfactant in the lungs?
- A. Reduce surface tension
- B. Enhance oxygen absorption
- C. Facilitate carbon dioxide release
- D. Increase lung volume
Correct answer: A
Rationale: The primary function of surfactant in the lungs is to reduce surface tension in the alveoli. This reduction in surface tension prevents lung collapse and allows for easier breathing. It is particularly crucial in premature infants to help with lung expansion. Choice B is incorrect because surfactant primarily affects surface tension, not oxygen absorption. Choice C is incorrect because surfactant's main role is not in facilitating carbon dioxide release. Choice D is incorrect because surfactant does not directly increase lung volume; its main role is in reducing surface tension.
3. A client has a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management during the postoperative period following a lumbar laminectomy. Which information should the PN reinforce about the action of the adjuvant pain modality?
- A. The discharge of electricity will distract the client's focus from the pain.
- B. An infusion of medication into the spinal canal will block pain perception.
- C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus.
- D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain.
Correct answer: D
Rationale: The TENS unit works by providing a mild electrical stimulus to the skin, which helps to 'close the gate' on pain signals, reducing the perception of pain. Choice A is incorrect because distraction is not the primary mechanism of action for TENS. Choice B is incorrect as it describes a different method of pain management involving medication infusion into the spinal canal. Choice C is incorrect as it inaccurately describes the location of pain perception modulation by the TENS unit.
4. A client who had a right total shoulder replacement is being prepared for discharge. What should the nurse emphasize to the client to prevent complications?
- A. Avoid lifting objects with the right arm until cleared by the surgeon.
- B. Perform shoulder exercises to regain strength.
- C. Use a sling at all times, even during sleep.
- D. Apply heat to the shoulder to reduce stiffness.
Correct answer: A
Rationale: The correct answer is to avoid lifting objects with the right arm until cleared by the surgeon. After a total shoulder replacement, it is essential to protect the new joint to prevent dislocation or injury. Lifting heavy objects prematurely can lead to complications. While performing shoulder exercises is important for strength, they should be done as per the healthcare provider's instructions to avoid strain on the new joint. Using a sling at all times, as in choice C, is not necessary once the client has regained enough strength and mobility. Applying heat, as in choice D, may not be recommended post-surgery; cold therapy is often preferred to reduce swelling and pain.
5. What is the function of the enzyme lactase in the digestive system?
- A. Breaks down lactose into glucose and galactose
- B. Breaks down proteins into amino acids
- C. Converts starch into maltose
- D. Breaks down fats into fatty acids
Correct answer: A
Rationale: The correct answer is A: 'Breaks down lactose into glucose and galactose.' Lactase is an enzyme in the small intestine that specifically breaks down lactose, the sugar found in milk, into glucose and galactose for absorption. Choice B is incorrect because proteins are broken down into amino acids by protease enzymes. Choice C is incorrect because the enzyme amylase converts starch into maltose. Choice D is incorrect as lipase enzymes break down fats into fatty acids.
